NEW QUESTION # 11
Refer to the exhibit.

A gateway cluster needs to be connected to the VSX-enabled switches where MC-LAG is configured What Is a possible constraint?

A. lacp mode active needs to be configured on the gateways when usingstatic-activate" mode.
B. LLDP needs to be enabled to detect LACP-configured interfaces.
C. The command lacp fallback is missing on the interface lag level.
D. LACP is not supported during the initial provisioning and needs to be turned off.

Answer: D

Explanation:
The question asks about a possible constraint when connecting an Aruba Gateway Cluster to upstream VSX switches using an MC-LAG.
* Scenario:Gateway Cluster acts as a single logical device forming an LACP LAG. The VSX switches are configured with MC-LAG, allowing the gateway cluster to bundle links across the two physical VSX switches.
* LACP & Initial Provisioning:LACP requires negotiation (exchange of LACP PDUs) between both ends of the link bundle to activate the LAG. During initial gateway provisioning (ZTP, OTP), the gateway might be in a minimal state without its full configuration, including LACP parameters. If the VSX switch ports are configured strictly for LACP active mode, the LAG might not form until the gateway is fully provisioned and running LACP. This lack of connectivity during provisioning is a constraint.
* Analysis of Options:
* A: lacp mode active is standard, but the issue is during provisioning, not runtime mode choice.
"static-activate" is unrelated.
* B: Theabsenceof lacp fallback could be the constraint. Fallback allows connectivity if LACP doesn't establish, which is useful during provisioning.
* C: LLDP is not required for LACP.
* D: Correctly identifies the constraint: Standard LACP required by the switch might not be supported or active on the gateway during its initial provisioning phase, potentially hindering the setup process. Workarounds like disabling LACP or enabling LACP fallback on the switch ports during this phase are often necessary.
* Conclusion:LACP incompatibility during the initial provisioning phase of the gateway cluster is a common constraint when connecting to switches requiring LACP for the LAG.

NEW QUESTION # 12
Refer to the exhibit.

IGMP v3 was enabled on both VSX switches. Which switch becomes the IGMP querier forclients connected to Ace-1 switch?

A. Active gateway IP will be used as IGMP querier.
B. Agg-2
C. both Agg-1 and Agg-2
D. Agg-1

Answer: D

Explanation:
The setup has Agg-1 and Agg-2 as a VSX pair with IGMPv3 enabled. Ace-1 is a downstream switch connected to clients. The question asks which switch becomes the IGMP querier for clients connected to Ace-
1.
* IGMP Snooping & Querier:In a Layer 2 network using IGMP snooping, an IGMP querier is required on each VLAN to periodically send general queries. This prompts hosts to send membership reports, allowing snooping switches to learn which ports need which multicast streams.
* Querier Election:If multiple devices capable of querying exist on a VLAN (like routers or capable switches), an election occurs. Typically, the device with the lowest IP address on the VLAN becomes the querier.
* VSX & IGMP Querier:In an ArubaOS-CX VSX environment, the IGMP querier functionality is managed by the VSX pair. Documentation indicates that theprimary VSX switchtypically assumes the role of the IGMP querier for the VLANs it serves, including those extended via MC-LAG to downstream switches.
* Analysis of Options:
* A. Agg-2: Would only be the querier if it were the primary VSX switch.
* B. Both Agg-1 and Agg-2: Incorrect, only one active querier per VLAN is standard.
* C. Agg-1: Likely the primary VSX switch (often designated or wins election based on priority
/lower system MAC/IP) and thus becomes the querier.
* D. Active gateway IP: This is the virtual IP used for unicast routing, but the querier function runs on a physical switch, usually the primary.
* Conclusion:Assuming Agg-1 is the primary VSX switch (as is common convention or based on default election parameters if not explicitly configured), it will act as the IGMP querier for the VLAN serving clients connected to Ace-1.

NEW QUESTION # 13
Refer to the exhibit which illustrates the current configuration of Router-1.

Clients of VLAN 10 require access to services hosted in the 10.1.100.0/24subnet. This 'equites one 01 more routes to be added to Rculer-1 that do not currently exist.
Which script would install a route from 10.2.10.0/24 to 10.1.100.0/24 on Router-1? A return path is not required as part of this answer.

A. ip route 0.0.0.0/0 10.255.101.11 vrf service
ip route 10.1.100.0/24 1/1/1 vrf IoT-Medical
B. there is no solution as Core-1 is not part of VRF service
C. ip route 0.0.0.0/0 10.255.101.11 vrf service
ip route 10.255.101.0/24 1/1/1 vrf IoT-Medical
ip route 10.1.100.0/24 10.255.101.11 vrf IoT-Medical
D. ip route 0.0.0.0/0 10.255.101.11 vrf service
ip route 10.1.100.0/24 1/1/1:10.255.101.11 vrf IoT-Medical

Answer: C

Explanation:
The goal is to add a static route on Router-1 to allow clients in VLAN 10 (subnet 10.2.10.0/24, presumably in VRF 'IoT-Medical' based on options) to reach services in the 10.1.100.0/24 subnet. The exhibit indicates interface 1/1/1 (IP 10.255.101.10/24) is in VRF 'service', and the likely next hop towards the destination is Core-1 at 10.255.101.11 (also implied to be reachable via VRF 'service'). This requires adding a route in the source VRF ('IoT-Medical') pointing towards the destination via the next hop in the 'service' VRF.
* Static Route Syntax (with VRF):ip route <destination_prefix> <next-hop-ip> [vrf <source-vrf>]
* Analysis of Options:
* A: Claims Core-1 isn't in VRF 'service', contradicting the likely setup.
* B: Uses unusual interface:ip syntax (1/1/1:10.255.101.11). Defines the route in VRF 'IoT- Medical'.
* C: Uses interface 1/1/1 as the next hop. This is less specific than using the IP address and relies on the interface being point-to-point or having proxy ARP enabled. Defines the route in VRF
'IoT-Medical'.
* D: ip route 10.1.100.0/24 10.255.101.11 vrf IoT-Medical. This uses the standard syntax to define a static route for the destination 10.1.100.0/24 via the next-hop IP 10.255.101.11 within the context of the IoT-Medical VRF. The successful function of this route depends on inter-VRF routing (route leaking) being configured between 'IoT-Medical' and 'service' VRFs, but the command itself correctly defines the desired static route.
* Conclusion:Option D provides the correct and standard command syntax to configure the required static route within the specified source VRF ('IoT-Medical').

NEW QUESTION # 14
You want to use OSPF to advertise a only .\16 summary route for the SVlsbelow to a neighbor In the same area (area 0).
Which configuration will achieve this?

Answer: C

Explanation:
The goal is to configure OSPF on a router so that it advertisesonlya 10.1.0.0/16 summary route for the specific SVIs (VLAN 11, 12, 13, assumed to be within the 10.1.x.x range) to its OSPF neighborswithin the same area (Area 0).
* OSPF Intra-Area Behavior:A fundamental principle of OSPF (link-state protocols) is that all routers within the same area must have an identical Link State Database (LSDB) for that area. This means all routers learn about all the specific networks (Type-1 Router LSAs, Type-2 Network LSAs) within their area. OSPFv2 doesnotsupport summarizing routes in a way that hides specific network LSAs from other routerswithin the same area. Summarization occurs only at area boundaries (by ABRs using Type-
3 Summary LSAs via the area range command) or for external routes redistributed into OSPF (by ASBRs using Type-5 External LSAs via the summary-address command).
* Analysis of Options:
* A) area 0 range 10.1.0.0/16:This command is used on an Area Border Router (ABR) to summarize routes originatingfromArea 0 when advertising theminto another area(e.g., the backbone). It does not affect LSA floodingwithinArea 0. It also includes redistribute connected, which is unrelated here.
* B) summary-address 10.1.0.0/16:This command is used on an Autonomous System Boundary Router (ASBR) to summarizeexternalroutes being redistributed into OSPF. It is not used for summarizing internal OSPF routes like SVIs defined within an OSPF area.
* C) & D) summary-address 10.1.0.0/16:Same issue as B; incorrect command for summarizing internal OSPF routes.
* E) area 0 range 10.1.0.0/16:Similar to A, this uses the area range command. It correctly shows the SVIs configured for OSPF Area 0 first. However, like A, this command performs inter-area summarization on an ABR and does not suppress the specific LSAswithinArea 0.
* Conclusion:The question asks for something that OSPFv2 cannot do: advertiseonlya summary route within the same area while suppressing specifics. Therefore, none of the configurations will achieve the exactstated outcome. However, if the question is flawed and intends to ask which configuration uses the correct command structure for summarizinginternalOSPF routes (even if only effective between areas), then the area range command is the relevant one. Both A and E use this command. Option E is slightly better structured as it shows the interfaces being added to OSPF Area 0 first. Assuming this is the intended direction despite the impossibility of the specific request, E is the most plausible choice among the given options.

NEW QUESTION # 15
Which issue may becausing the new door locks on the APs to notwork?

A. AF power to the AP is not enough.
B. AT power to the AP is notenough.
C. AT power to the AP is too much.
D. BT power to the AP is too much.

Answer: A

Explanation:
New PoE-powered door locks, connected via the PoE passthrough port on Aruba APs, are not working. We need to find the likely cause related to PoE power.
* PoE Passthrough:An AP feature where the AP, powered by PoE from a switch, provides PoE power out to another device connected to one of its Ethernet ports.
* Power Budget:The AP must receive enough power from the switch via its PoE input (e.g., 802.3af,
802.3at, 802.3bt) to power itselfandmeet the power demand of the downstream device (the door lock).
* PoE Standards Power (Approx. Available to Device):
* 802.3af (PoE): ~13 Watts
* 802.3at (PoE+): ~25.5 Watts
* 802.3bt (PoE++): 51W (Type 3) or 71W (Type 4)
* Analysis:Modern APs (especially Wi-Fi 6/6E) can consume significant power themselves (>15W or
>25W under load). Standard 802.3af PoE (supplying only ~13W) is often insufficient to power both a modern AP and a downstream PoE device like a door lock. The AP will power up, but won't enable PoE output if its input power budget is insufficient.
* Analysis of Options:
* A, B: Too much power (AT/BT) isn't the issue; devices only draw what they need.
* C: AF power (~13W) received by the AP is very likelynot enoughto power both the AP and the door lock.
* D: AT power (~25.5W)mightbe insufficient if the combined load of the AP and lock exceeds this, but AF being insufficient (C) is a more common limitation.
* Conclusion:Insufficient input power to the AP is the most common reason for PoE passthrough failure.
802.3af (PoE) power is often inadequate.

NEW QUESTION # 16
Exhibit.

A conference venue has a requirement to secure independent network users from each other in their network.
The following configurations are created on Edge-1:

A. change the VLAN 152 type. primary-vlan 152
B. change the VLAN 152 private-vlan community
C. change the VLAN 151 primary-vlan 151
D. change the VLAN 151 private-vlan community

Answer: D

Explanation:
The requirement is to secure independent network users from each other in a conference venue using Edge-1.
This scenario typically calls for Private VLANs,specifically using the 'isolated' type to prevent communication between hosts within the same secondary VLAN.
* Analysis of Options:
* Private VLANs consist of a primary VLAN and one or more secondary VLANs (isolated or community). Isolated ports cannot communicate with other isolated ports in the same VLAN; they can only communicate with promiscuous ports (usually the router uplink). Community ports can communicate with each other and promiscuous ports.
* Option A: Configures VLAN 152 as private-vlan community.
* Option B: Configures VLAN 151 as private-vlan community.
* Option C: Defines VLAN 152 as a primary-vlan associated with itself, which isn't standard syntax
/logic.
* Option D: Defines VLAN 151 as a primary-vlan associated with itself.
* The goal isisolation. None of the options directly configure an isolated VLAN. Options A and B configure community VLANs, which allow communication between users within that VLAN, contradicting the requirement. Options C and D attempt to define primary VLANs in a potentially incorrect way.
* Caveat:There seems to be an issue with the provided options. Standard configuration to make VLAN 151 isolated would involve defining a primary VLAN (e.g., vlan 152 private-vlan primary) and then defining VLAN 151 as isolated (vlan 151 private-vlan isolated). Since none of the options correctly configure anisolatedVLAN, and the requirement is isolation, the question or options are likely flawed. However, if forced to interpret intent, questions sometimes test understanding of thetypesof private VLANs. Changing a VLANtocommunity type (Option B for VLAN 151) is a distinct action, even if it doesn't meet the statedisolationgoal. Without correct options for 'isolated', selecting the 'best' flawed option is difficult. Assuming the question intends to configure VLAN 151 assome typeof private secondary VLAN, Option B modifies VLAN 151's private VLAN characteristic.
* Conclusion:Based on the requirement for isolation, none of the provided options are correct. However, if assuming a potential error in the question or options and needing to select the closest modification related to private VLAN types for VLAN 151, Option B is chosen tentatively, despite configuring
'community' instead of the required 'isolated'.

NEW QUESTION # 17
Refer to the four numborod slops in the exhibit.

Which action is the fourthstep in applying a role-to-role ACL on thetraffic from mobile device M1 to roleH2?

A. The edge switch acts as the intermediate node and transfers the Group Policy ID over static VXLAN to dynamic VXLAN tunnel and forwards the packet to switch Al.
B. Switch A1 determines the destination role based on destination MAC or destination IP and enforces role-to-role ACLs.
C. Gateway 1 forwards thetraffic over the sialic VXLAN tunnel to the edge switch; this packet carries the Group Policy ID corresponding to the role ofM1.
D. The AP forwards the packet from M1 to gateway 1.

Answer: B

Explanation:
The question asks for the fourth step in applying a role-to-role ACL on traffic from a mobile device (M1) to a role (H2) in a network using Dynamic Segmentation with VXLAN. This follows question 17, which identified the first step as the AP forwarding the packet to the gateway.
* Analysis of Options:
* Option A:Correct. The fourth step involves the destination switch (Switch A1) determining the destination role (H2) based on the destination MAC or IP address and applying the role-to-role ACL to permit or deny the traffic.
* Option B:Describes an earlier step (likely second or third) where the gateway forwards traffic over a VXLAN tunnel.
* Option C:Describes the first step, as identified in question 17.
* Option D:Describes an intermediate step (likely third) where the edge switch transfers the Group Policy ID over VXLAN.
* Why Option A is Correct:In HPE Aruba Networking's Dynamic Segmentation architecture, the traffic flow for role-based ACLs in a VXLAN environment follows these steps:
* The AP forwards the packet from M1 to the gateway (question 17).
* The gateway assigns the source role (M1's role) and forwards the packet over a VXLAN tunnel with the Group Policy ID.
* The edge switch transfers the Group Policy ID to the destination switch (A1) via VXLAN.
* Switch A1 determines the destination role (H2) based on the destination MAC or IP address and enforces the role-to-role ACL, as defined in the Group-Based Policy (GBP).
The fourth step is critical for policy enforcement, ensuring that traffic complies with the security policies defined between the source and destination roles, providing secure network segmentation.
* Relevance to Certification Objectives:
* Security (10%):Designing and troubleshooting role-based security policies in customer networks.
* Switching (19%):Implementing Layer 2/3 interconnection technologies like VXLAN for policy enforcement.
* WLAN (9%):Troubleshooting wireless traffic flows in Dynamic Segmentation.

In the given example AGG-SW1 and AGG-SW2 use CX 8325 in VSX and Edge-1 withCX 6200F. You want toavcwl sub-optimal path.ng and ISL traffic for the VSX and upstream routers R1 and R2.
What is the HPE Aruba Networkingrecommended solution for me SVIs on the VSX switches connected to R1 and R2?

A. Configure the VSX SVI using the active-forwarding.
B. Configure the VSX SVI using the active-gateway.
C. Configure the VSX SVI using the VRRP virtual-ip.
D. Configure the VSX SVI using the uncast IP.

Answer: A

Explanation:
The scenario involves a VSX pair (AGG-SW1/SW2) connected upstream to routers R1/R2. The goal is to configure the SVIs on the VSX switches facing these upstream routers optimally to avoid suboptimal L3 paths and unnecessary traffic over the VSX Inter-Switch Link (ISL).
* VSX L3 Interface Options:
* Active Gateway:Primarily designed for downstream SVIs to provide a redundant default gateway to clients/access switches. Not typically used for upstream routed interfaces.
* Active Forwarding:Specifically designed for upstream routed interfaces (physical or SVIs) on a VSX pair. It allows both VSX members to actively route traffic arriving on that interface locally, without needing to forward L3 traffic across the ISL. This ensures optimal routing and utilizes both members effectively.
* Unicast IP (Standard IP):Without specific VSX features, standard routing applies. This could lead to suboptimal paths if, for example, return traffic prefers one VSX switch, but the optimal path requires crossing the ISL.
* VRRP:Can be run between VSX members but adds complexity and is generally superseded by Active Gateway (downstream) or Active Forwarding (upstream) in VSX designs.
* Analysis of Options:
* A. Configure active-forwarding: This enables local L3 forwarding on both VSX members for the upstream SVI, preventing unnecessary ISL traversal for routed traffic. This is the recommended best practice.
* B. Configure unicast IP: Standard configuration, potentially leading to suboptimal paths/ISL usage.
* C. Configure VRRP virtual-ip: Not the recommended approach for upstream links in VSX.
* D. Configure active-gateway: Incorrect, Active Gateway is for downstream SVIs.
* Conclusion:Using active-forwarding on the SVIs facing the upstream routers (R1/R2) is the HPE Aruba Networking recommended solution to ensure optimal routing and minimize L3 traffic across the ISL.

NEW QUESTION # 19
Refer to the exhibit and cede sample.

What is the effect when you add thestatement "neighbor 10.2.0.3 send-community both" to the ipv4 address family? (Select two.)

A. It causes R1 to negotiate the ability to send and receive standard and extended communities with R2.
B. The feature will be enabled without consequence to the R1established session with R2.
C. It will cause existing BGP peering between R1and R2 to flap.
D. Itcauses R1to allow the exchange ofcommunities with NLRI records in both inbound and outbound direction
E. It causes R1to negotiate for the ability to import and export all type-1 and lype-2 communities with R2.

Answer: A,C

Explanation:
The question asks for the effects of adding the command neighbor 10.2.0.3 send-community both to the BGP configuration under the IPv4 address family context for neighbor R2 (10.2.0.3) on router R1.
* send-community both:This command instructs R1 to send both standard (RFC 1997) and extended (RFC 4360) BGP community attributes to neighbor R2. By default, communities are not sent.
* BGP Capability Negotiation:Adding or changing features like community advertisement modifies the BGP capabilities exchanged between neighbors during session establishment. Any change to these capabilities requires the BGP session to be reset (flap) so that the peers can renegotiate using the new capabilities.
* Analysis of Options (Select Two):
* A: Correct (partially). It enables R1 tosendstandard and extended communities. The ability to receivedepends on the peer and local config. The capability isnegotiatedupon session reset.
* B: Incorrect. Changing capabilities requires the session to flap; it's not without consequence.
* C: Incorrect. It primarily enablesoutboundsending from R1. Inbound acceptance is implicit if the neighbor is activated.
* D: Correct. Modifying BGP neighbor capabilities, such as enabling send-community, necessitates a BGP session reset (flap) for the change to take effect.
* E: Incorrect terminology ("import/export", "type-1/type-2 communities").
* Conclusion:The command enables R1 to send communities (A describes the purpose/capability), and adding this command to an existing session will cause the session to flap for renegotiation (D describes the immediate consequence).

NEW QUESTION # 20
Aplying the command "ip Igmp snooping blocked VLAN 6. 6* on a port ...

A. won't allow multicast on that port in VLAN 5 and 6 and disables the port.
B. won't accept multicast Igmp joins on that port or VLAN 5 and 6.
C. won't prune multicast on that port on VLAN 5 and 6
D. won't allow multicast traffic between VLAN 5 and 6.

Answer: B

Explanation:
The question asks for the effect of applying the command ip igmp snooping blocked vlan 5,6 on a switch port.
* ip igmp snooping blocked vlan <vlan-list>:This interface configuration command instructs the IGMP snooping process on the switch to block (ignore/drop) any inbound IGMP control packets (specifically Membership Reports, i.e., "joins", and Leave messages) received on this port for the specified VLANs (5 and 6 in this case).
* Effect:By blocking IGMP join messages from hosts connected to this port, the switch will not learn about any multicast group memberships requested by those hosts in VLANs 5 and 6. Consequently, the switch will not forward multicast traffic for those groups out of this port for those VLANs (unless the port is designated as a multicast router port). It effectively prevents hosts on this port from receiving multicast streams in the specified VLANs via standard IGMP mechanisms.
* Analysis of Options:
* A: Itresultsin traffic effectively being pruned because memberships aren't learned, but the command itself blocks the IGMPcontrolpackets (joins).
* B: Correct. It stops the switch from accepting IGMP join messages on this port for VLANs 5 and
6.
* C: Incorrect. It doesn't control inter-VLAN traffic.
* D: Incorrect. It doesn't disable the entire port.
* Conclusion:The command specifically blocks the reception and processing of IGMP join messages on the configured port for the listed VLANs.

NEW QUESTION # 21
You see the output unknown the first time you in the command, but the next time you see the following information displayed.

What aresome things you could took at in the switch to troubleshootthe issue? (Select two.)

A. diag cable-diagnostic 1/1/X
B. diag 1/1/X transceiver all
C. diag interface transceiver al
D. diag cable 1/1/X
E. diag interface 1/VX transceiver all

Answer: A,B

Explanation:
The question involves troubleshooting an issue where the command output is initially unknown, but subsequent executions show diagnostic information for an interface (1/1/X). The task is to identify appropriate diagnostic commands to troubleshoot the issue.
* Analysis of Options:
* Option A (diag interface transceiver al):Incorrect syntax; "al" is not a valid parameter.
* Option B (diag interface 1/VX transceiver all):Incorrect syntax; "1/VX" is not a valid interface format.
* Option C (diag cable-diagnostic 1/1/X):Correct. This command runs a cable diagnostic test (TDR) on interface 1/1/X to check for cable faults, such as opens or shorts.
* Option D (diag cable 1/1/X):Incorrect; "diag cable" is not a valid AOS-CX command.
* Option E (diag 1/1/X transceiver all):Correct. This command displays detailed transceiver information, including status, errors, and signal quality, useful for diagnosing interface issues.
* Why C and E are Correct:The diag cable-diagnostic 1/1/X command is used to perform TDR tests to identify cable faults, which could cause connectivity issues. The diag 1/1/X transceiver all command provides detailed transceiver diagnostics, such as power levels, errors, or hardware issues, helping pinpoint problems with the interface or connected device. These commands align with AOS-CX troubleshooting workflows for physical layer issues.
* Relevance to Certification Objectives:
* Troubleshooting (10%):Involves using diagnostic commands to troubleshoot campus network issues.
* Connectivity (9%):Includes identifying problem areas in device deployment, such as cabling or transceiver issues.

NEW QUESTION # 23
Match the network technology to the customer requirement.

Answer:

Explanation:

* Establish redundant links between the aggregation and core layers:When using Layer 3 routing between network layers (like Aggregation and Core),ECMP (Equal Cost Multi-Path)allows the routing protocol (e.g., OSPF, BGP) to utilize multiple links simultaneously if they have the same routing cost. This provides both redundancy (if one link fails, traffic uses the others) and load sharing across the links.
References:AOS-CX IP Routing Guide (OSPF, BGP, ECMP). Relates to "Routing" (16%), "Network Resiliency and virtualization" (8%).
Extend layer 2 across multiple sites:VXLAN (Virtual Extensible LAN)is the overlay technology specifically designed for this purpose. It encapsulates Layer 2 Ethernet frames within UDP packets, allowing them to be tunneled across an underlying Layer 3 network infrastructure, effectively stretching Layer 2 domains (VLANs) between physically separate locations.
References:AOS-CX VXLAN Guide.Relates to "Switching" (19%), "Connectivity" (9%).
Identify individual layer 2 segments in an overlay:Inside the VXLAN header, theVNI (VXLAN Network Identifier)serves as the segment identifier. Each unique Layer 2 segment (like a specific VLAN being extended) is mapped to a unique 24-bit VNI, allowing the overlay network to differentiate between traffic belonging to different L2 domains, even when tunneled between the same VTEPs (VXLAN Tunnel Endpoints).
References:AOS-CX VXLAN Guide, RFC 7348 (VXLAN).Relates to "Switching" (19%), "Connectivity" (9%).
Minimize configuration steps to establish tunnels between sites:While VXLAN provides the data plane encapsulation,EVPN (Ethernet VPN)acts as the modern control plane for VXLAN overlays. Using MP-BGP extensions, EVPN dynamically discovers VTEPs and advertises MAC address and IP reachability information. This significantly reduces configuration complexity compared to older static VXLAN or flood- and-learn methods, as VTEP peer relationships and endpoint learning are automated by the control plane, thus minimizing manual steps to establish connectivity.

NEW QUESTION # 25
Acme is having BGP issues with its AOS-CX switch and has asked you to helptroubleshoot the issue You have access to the CLI ofthe switch. Which command can you use to begin troubleshooting?

A. show run | route destination!
B. show debug start
C. snow buffer | debug
D. show debug destinations

Answer: D

Explanation:
The question involves troubleshooting BGP issues on an AOS-CX switch, and the task is to identify the appropriate CLI command to begin the troubleshooting process.
* Analysis of Options:
* Option A (show run | route destination):Incorrect syntax; the show running-config command with a filter is not specific to BGP troubleshooting.
* Option B (show debug start):Incorrect; AOS-CX does not use show debug start for initiating debugging.
* Option C (show buffer | debug):Incorrect; this is not a valid AOS-CX command for BGP troubleshooting.
* Option D:Correct. The show debug destinations command displays the current debug settings, including whether BGP debugging is enabled, which is a critical first step in troubleshooting BGP issues.
* Why Option D is Correct:To troubleshoot BGP issues, the first step is to verify if debugging is enabled for BGP events, as this provides detailed logs of session states, messages, and errors. The show debug destinations command on AOS-CX switches shows which debug types (e.g., BGP) are active and where logs are sent (e.g., console, syslog). If BGP debugging is not enabled, the administrator can enable it using debug bgp to capture relevant information, making this the ideal starting point for BGP troubleshooting.
* Relevance to Certification Objectives:
* Troubleshooting (10%):Involves performing advanced troubleshooting of routing protocols like BGP.
* Routing (16%):Includes diagnosing BGP session and configuration issues.

NEW QUESTION # 26
Match the AOS-CX switch BGP keepalive and holddown timersto the default.

Answer:

Explanation:

Explanation:

The question requires matching the default BGP keepalive and hold-down timers on AOS-CX switches to their respective values.
* Analysis of Options:
* Keepalive Timer:The keepalive timer determines how often BGP keepalive messages are sent to maintain a session. The default value on AOS-CX switches is 60 seconds.
* Hold-down Timer:The hold-down timer specifies the maximum time a BGP session can remain active without receiving a keepalive or updatemessage before it is considered down. The default value on AOS-CX switches is 180 seconds.
* Why This Mapping is Correct:Per BGP standards (RFC 4271) and HPE Aruba Networking AOS-CX documentation, the default BGP keepalive timer is 60 seconds, and the hold-down timer is 180 seconds (three times the keepalive interval). These timers ensure BGP sessions remain stable while allowing timely detection of peer failures. The AOS-CX implementation adheres to these defaults unless explicitly configured otherwise.
* Relevance to Certification Objectives:
* Routing (16%):Involves designing and troubleshooting BGP routing topologies, including timer configurations.
* Troubleshooting (10%):Includes diagnosing BGP session issues related to timers.

NEW QUESTION # 27
A customer hassot a requirement for VLAN 151 to be an isolated VLAN. A colleague has copied and pasted a partialconfiguration, but you do not achieve the desired outcome. This is the code that was added:
What should be added to the configuration before this code to achieve the desired result?

Answer: A

Explanation:
The customer requires VLAN 151 to be configured as an isolated Private VLAN. A partial configuration was added, but the desired outcome wasn't achieved. We need to determine which configuration snippet should be addedbeforethe (unspecified) partial configuration to correctly set up the Private VLAN structure.
* Private VLAN Configuration Fundamentals:
* APrimary VLANmust be defined. This VLAN carries traffic between promiscuous ports and ports in associated secondary VLANs.
* Secondary VLANs(either isolated or community) are associated with the primary VLAN.
* Ports are then mapped to either the primary VLAN (promiscuous ports, typically router/firewall connections) or a secondary VLAN (host ports). Isolated ports within thesameisolated VLAN cannot communicate with each other.
* Analyzing the Options (Assuming VLAN 15 is the intended Primary):
* A)
vlan 15
private-vlan primary
vsx-sync
This correctly defines VLAN 15 as the Primary Private VLAN. The vsx-sync command ensures this configuration is synchronized across a VSX pair (relevant if applicable). This is the necessary prerequisite before defining VLAN 151 as an isolated secondary VLAN and associating it with VLAN 15.
* B)isolated-vlan primary is incorrect syntax. The command is private-vlan primary.
* C)primary-vlan isolated 151 is incorrect syntax for defining either the primary or secondary VLAN type/association within the primary VLAN context.
* D)private-vlan isolated 151 within the vlan 15 context is incorrect syntax. The private-vlan isolated command belongs under the configuration of the secondary VLAN (VLAN 151 in this case).
* Conclusion:Before configuring VLAN 151 as private-vlan isolated and associating it, the primary VLAN must be defined. Option A correctly shows the command (private-vlan primary) under the intended primary VLAN's configuration (vlan 15) to establish it as the primary VLAN.

NEW QUESTION # 28
What is the correct sequence of events that occurs when a user device connects to a network using Dynamic Segmentation?

Answer:

Explanation:

Explanation:

This question asks for the sequence of events when a user device connects to a network utilizing Dynamic Segmentation, which typically involves authentication via ClearPass and role-based policy assignment.
* Authentication:When a device connects (wired or wireless), the first step in gaining secure access is authentication. The switch or AP (authenticator) facilitates this process, usually communicating via RADIUS with ClearPass Policy Manager (RADIUS server). The device provides credentials or uses certificates (e.g., 802.1X, MAC Auth).
* Role Assignment:Upon successful authentication, ClearPass evaluates policies based on the device
/user context (identity, posture, time of day, etc.) and sends back RADIUS attributes to the authenticator. A crucial attribute is the assigned User Role. This role encapsulates the access privileges and network configuration for the device.
* Network Placement/Segmentation:The authenticator (switch/AP) uses the assigned role information received from ClearPass to place the device into the appropriate network segment. This might involve assigning a specific VLAN ID to the port/client or, in User-Based Tunneling (UBT) scenarios, establishing a tunnel to an Aruba Gateway associated with that role. The step "placed on a VLAN based on its role" describes one common method of segmentation based on the assigned role.
* Access Granted:Once the device is authenticated, assigned a role, and placed in the correct network segment (VLAN or tunnel), access is granted according to the firewall rules, QoS settings, and other policies defined within that assigned role. Traffic can now flow subject to these enforced policies.

NEW QUESTION # 29
Exhibit.

The customer has VSX clusters intwo locations interconnected over an MC-LAG interface.
If active-gateway configuration uses the same virtual IP address and vMAC on each of the VSX nodes, what must you take into consideration0

A. The configuration would end up in an async setup.
B. Each ARP request will result in four responses.
C. Outbound traffic will be load-balancedover all VSX members for each session.
D. Transit traffic will Increase over the VSX interconnect MC-LAG.

Answer: A

Explanation:
The scenario describes two separate VSX clusters interconnected via MC-LAG, where both clusters are configured to use theexact samevirtual IP address and virtual MAC address for their respective Active Gateway SVIs.
* Active Gateway Scope & Conflict:Active Gateway provides a highly available default gatewaywithina single VSX cluster (L2 domain). The vIP/vMAC combination should be unique within its L2 broadcast domain.
* Interconnecting Clusters with Same vIP/vMAC:When two VSX clusters using the identical Active Gateway vIP/vMAC are interconnected at Layer 2 (even via MC-LAG), this creates a situation where the same active L2 (vMAC) and L3 (vIP) address exists in multiple places within the extended broadcast domain.
* Consequences:This leads to MAC address conflicts and L3 ambiguity. ARP resolution becomes unreliable, potentially causing ARP tables to flap on connected devices. Traffic forwarding becomes unpredictable, as packets destined for the vIP/vMAC might be delivered to the "wrong" cluster. This unstable and unpredictable state is sometimes referred to as an asymmetric or "async" setup.
* Analysis of Options:
* A: ISL traffic might change, but it's a symptom, not the root problem.
* B: Multiple ARP replies would occur, contributing to the confusion.
* C: The configuration results in an "async setup," accurately describing the unstable state caused by duplicate active L2/L3 addresses across the interconnected L2 domain.
* D: Load-balancing happens within a cluster; this setup causes conflict, not predictable load balancing across clusters.
* Conclusion:Reusing the same Active Gateway vIP and vMAC across interconnected VSX clusters is not a valid design and leads to an unstable, asymmetric ("async") environment due to address duplication within the extended L2 domain. Option C best describes this problematic outcome.

NEW QUESTION # 30
With the configuration oftwo CX 8325 switches in the VSX cluster, how would you prepare a link- aggregation for a 7000 gateway for a zero-touch provision to support protocol-based port redundancy?

Answer: A

Explanation:
The goal is to configure a Link Aggregation Group (LAG) on a VSX cluster (pair of CX 8325 switches) that connects to an Aruba 7000 series gateway undergoing Zero Touch Provisioning (ZTP). The LAG needs to support "protocol-based port redundancy" (LACP) and allow connectivity during ZTP.
* VSX Requirement:Since the LAG connects to two separate physical switches operating as a VSX pair, the LAG must be configured as a Multi-Chassis LAG (MC-LAG) on the switches. This allows the gateway to form a single LAG across both upstream devices. The command multi-chassis under the interface lag <id> context enables this.
* Protocol Redundancy Requirement:"Protocol-based port redundancy" indicates that Link Aggregation Control Protocol (LACP) should be used to dynamically negotiate and manage the LAG bundle between the switches and the gateway. The command lacp mode active enables LACP in active negotiation mode.
* ZTP Requirement:During ZTP, the gateway might not have its full configuration, including LACP settings, enabled immediately. To ensure the gateway can establish basic IP connectivity for ZTP (e.g., reach Activate/Central via DHCP/DNS), the switch ports should allow traffic even if LACP negotiation hasn't completed. The lacp fallback feature enables this, allowing individual LAG member ports to become active if LACP PDUs are not received from the peer.
* Analyzing the Options:
* A)Configures lacp mode active and lacp fallback butlacksthe multi-chassis command required for VSX.
* B)Correctly configures the LAG as multi-chassis, enables lacp mode active, and enables lacp fallback. This meets all requirements.
* C)Configures multi-chassis but uses potentially older or less standard syntax lacp enable and lacp fail-over instead of lacp mode active and lacp fallback.
* D)Lacks the multi-chassis command and uses potentially older/less standard syntax.
* Conclusion:Option B provides the complete and correct configuration using standard AOS-CX syntax to create an MC-LAG on the VSX pair with LACP enabled for redundancy and LACP fallback enabled to support gateway connectivity during ZTP.

After an initial setup of CX 8325 VSX configuration, the active gateway is set up for SVI 10. For testing purposes. SVI 10 on sw-aggi is shut down while traffic from the client connected to Edge-1 is initiated towards the default route.
What is the expected behavior white performing this test?

A. Traffic is dropped and vsx-sync will disable SVI10 on agg-sw2 automatically.
B. Traffic is potentially dropped between the client and the destination.
C. Traffic Is unaffected and a 50nsfailover time is expected for agg-sw2 to start traffic forwarding.
D. Traffic is forwarded over the ISL without the risk of dropped packets.

Answer: C

Explanation:
The question involves a VSX configuration with CX 8325 switches (agg-sw1 and agg-sw2) where SVI 10's active-gateway is set up. For testing, SVI 10 on agg-sw1 is shutdown, and traffic from a client connected to Edge-1 is initiated toward the default route. The task is to determine the expected behavior.
* Analysis of Options:
* Option A:Incorrect. Traffic is not dropped, as VSX ensures redundancy via the active-gateway on agg-sw2.
* Option B:Incorrect. Traffic does not traverse the ISL unnecessarily; agg-sw2 takes over directly.
* Option C:Correct. Traffic continues unaffected, with a 50ms failover time for agg-sw2 to assume forwarding responsibilities for SVI 10.
* Option D:Incorrect. Traffic is not dropped, and vsx-sync does not disable SVI 10 on agg-sw2; it ensures consistency.
* Why Option C is Correct:In a VSX cluster with active-gateway, both switches (agg-sw1 and agg- sw2) share a virtual IP and vMAC for SVI 10, allowing either to respond to ARP requests and forward traffic. Shutting down SVI 10 on agg-sw1 triggers agg-sw2 to take over Layer 3 forwarding, leveraging the active-gateway configuration. VSX's fast failover mechanism ensures a typical failover time of approximately 50ms, making the transition seamless for clients on Edge-1. The vsx-sync feature ensures SVI configurations remain consistent, preventing traffic disruption. This behavior aligns with HPE Aruba Networking's VSX high-availability design.

NEW QUESTION # 32
You arc about lo deploy a gateway that is on factory default. ZTP cannot be used for different reasons, but you are searching forvalid alternatives. What are two valid alternatives for ZTP? (Select two.)

A. Use OTP by connecting lo the console port, and use terminal software to complete provisioning. *Static- Activate" should be used.
B. Use OTP by connecting to the console port, and use terminal software to complete provisioning. "Full- Setup" should be used.
C. Use OTP by connecting to port 0/0/0. and use a Web browser to complete provisioning.
D. UseOTP by connecting to port 0/0/1. and use a Web browser to completeprovisioning.
E. Use OTP by connecting to port 0/0/1 with a static IP. and use a Web browser to complete provisioning.

Answer: B,D

Explanation:
The question asks for valid alternatives to Zero Touch Provisioning (ZTP) for initially configuring a factory default Aruba gateway when ZTP cannot be used.
* Aruba Gateway Initial Provisioning Methods:
* ZTP:Automated provisioning using Activate/Central.
* One-Touch Provisioning (OTP) / Manual Setup:Involves direct connection for initial configuration.
* Web UI:Connecting a laptop to a specific management or designated setup port (often GE0
/0/1 on many gateway models) allows access to a web-based setup wizard.
* Console Port:Connecting via the serial console port allows CLI access, which includes guided setup scripts or manual configuration.
* Analysis of Options:
* A: Port 0/0/0 is typically the OOBM port, not the standard OTP web UI port.
* B: Port 0/0/1 is commonly used for OTP via Web browser on many Aruba gateway models.
* C: Using the console port with terminal software for initial setup (potentially using a "Full-Setup" wizard or script) is a standard manual method.
* D: "Static-Activate" refers to manual registration with the Activate service, not a console setup mode.
* E: Requires setting a static IP, adding complexity beyond the basic OTP connection method described in B.
* Conclusion:Using the designated OTP Ethernet port (commonly GE0/0/1) with a web browser (Option B) and using the console port with terminal software (Option C) are the standard, valid alternatives to ZTP for initial gateway setup.

NEW QUESTION # 33
What is the best practice for using Dynamic Segmentation?

A. Use a combination of role-based access and overlay technologies to create a layered security approach.
B. Use UBT to create isolated networks foe specific typos of devices.
C. Use Dynamic Segmentation only on devices thatare connected to the network via Wi-Fi.
D. Use LUR to assign roles to devices based on their location and DUR to assign roles to devices based on their user identity.

Answer: A

Explanation:
The question asks for the best practice for using Dynamic Segmentation.
* Dynamic Segmentation Overview:It's an architecture that provides unified policy and segmentation for wired and wireless clients by combining role-based access control, traffic tunneling (like UBT), and overlay technologies (like VXLAN/GRE). Policies are enforced centrally, typically at an Aruba Gateway.
* Analysis of Options:
* A: UBT is a component, but Dynamic Segmentation encompasses more than just creating isolated networks with UBT.
* B: Correctly describes the core principle: using a combination of role-based access (for defining whogetswhatpolicy) and overlay technologies (for transporting traffic to the policy enforcement point and providing segmentation). This creates a layered security approach.
* C: Incorrect. A key benefit isunifiedpolicy across both wired and wireless access.
* D: LUR and DUR are role types, but how they are assigned isn't the fundamental description of Dynamic Segmentation itself.
* Conclusion:Option B accurately captures the essence of Dynamic Segmentation as a best practice approach, integrating role-based policies with overlay networking for secure, unified access control.

NEW QUESTION # 34
The customer is experiencing periodic uplink congestion between campus-1's AGG-1 and core. This has boon negativelyaffecting voice communications.The VOIP phones edge mark their packets with DSCP EF. The uplink from AGG-1 to core is LAG1.
The customer has already configured the following class and policy on AGG-1:

Based on this policy, which scrip), when deployed on AGG-1. will improve the reliable forwarding of voice trafficbetween AGG-1 and its uplink to the core?

Answer: C

Explanation:
The problem describes uplink congestion affecting VoIP traffic (marked with DSCP EF, value 46) on AGG-
1's LAG1 uplink. The existing configuration classifies this traffic into voip_class and applies voip_policy inbound, setting local-priority 6. To improve reliable forwarding during congestion, VoIP traffic needs strict priority queuing on the egress interface (LAG1).
* Analysis of Options:
* Option A applies a QoS schedule profile globally but doesn't modify the policy's local-priority or apply the schedule profile specifically to the congested LAG.
* Option B modifies voip_policy to set local-priority 7 (mapping DSCP 46 traffic to queue 7) and applies the 8qDwrStrict schedule profile to the egress interface lag 1. In the 8qDwrStrict profile, queue 7 is configured for strict priority, ensuring voice traffic gets precedence over lower-priority traffic during congestion. This aligns with best practices for QoS for VoIP.
* Option C also sets local-priority 7 and applies the schedule profile to lag 1, but the profile itself configures queue 7 with DWRR (Deficit Weighted Round Robin) instead of strict priority, which is less suitable for delay-sensitive voice traffic.
* Option D applies a schedule profile globally and uses DWRR for queue 7.
* Conclusion:Option B is the correct solution because it maps the DSCP EF traffic to the highest local priority (7) and applies a QoS schedule profile to the specific congested uplink (lag 1) that treats queue
7 with strict priority. This ensures voice traffic is prioritized reliably.

NEW QUESTION # 35
You haverecently configured a switch for 802.IX authentication with HPE Aruba Networking ClearPass. A security admin is seeing events withthe following description in ClearPass Event Viewer.
RADIUS authentication attempt from unknown NAD (10.10.1.10:1812)'
Which command should you us to identify theconfiguration issue?

A. show ip source-interfaceradius
B. show radius-server shared-secret
C. show radius-server detail
D. show aaa authentication-server radius

Answer: A

Explanation:
The ClearPass Event Viewer message "RADIUS authentication attempt from unknown NAD (10.10.1.10:
1812)" indicates that ClearPass received a RADIUS request from the IP address 10.10.1.10, but this IP is not configured as a trusted Network Access Device (NAD) in ClearPass's network device list, or the shared secret doesn't match. The first step in troubleshooting on the switch side is to verify which source IP address the switch is actually using to send these RADIUS requests.
* RADIUS Source IP:AOS-CX switches can be configured to use a specific source IP address for RADIUS packets, often using the ip source-interface radius [vrf <vrf-name>] command. This is important if the switch has multiple IP interfaces or uses VRFs.
* Analysis of Commands:
* A. show ip source-interface radius: This command directly displays the configured source interface and IP address used for RADIUS communications, allowing comparison with the IP configured in ClearPass.
* B. show aaa authentication-server radius: Shows server group configuration, not the source IP used by the switch.
* C. show radius-server shared-secret: Not a standard command; secrets are usually masked in other commands.
* D. show radius-server detail: Shows configured RADIUS server details but doesn't explicitly show the source IP the switch is using to originate packets.
* Conclusion:To identify why ClearPass sees requests from an "unknown NAD" IP (10.10.1.10), the first step on the switch is to confirm which source IP it's using. show ip source-interface radius provides this crucial information.
