NEW QUESTION # 41
A virtual server is configured to offload SSL from a pool of backend servers. When users connect to the virtual server, they successfully establish an SSL connection but no content is displayed. A packet trace performed on the server shows that the server receives and responds to the request. What should a BIG-IP Administrator do to resolve the problem? (Choose one answer)

  • A. disable Server SSL profile
  • B. disable SNAT
  • C. enable SNAT
  • D. enable Server SSL profile

Answer: C

Explanation:
This scenario describes a classic case of asymmetric routing in a "one-arm" or non-gateway deployment.
When a BIG-IP system is configured for SSL offloading, the following traffic flow occurs:
Client-Side: The client establishes a successful SSL/TLS handshake with the Virtual Server. This explains why the user can "successfully establish an SSL connection." Server-Side: The BIG-IP decrypts the traffic and forwards it as plain HTTP to the backend server. The packet trace confirms the server receives the HTTP GET request and responds with the content.
The Routing Failure: By default, the BIG-IP system preserves the client's original source IP address. If the backend server's default gateway is not the BIG-IP system (or if the server is on the same subnet as the client), the server will attempt to send the response directly back to the client's IP address, bypassing the BIG-IP.
Stateful Drop: Because the BIG-IP is a Full Proxy, it expects the response to return through its own internal state table to be encrypted and sent back to the client. Since the response bypasses the BIG-IP, the BIG-IP connection eventually times out, and the client receives no data despite the server having sent it.
Solution (SNAT): Enabling Secure Network Address Translation (SNAT), specifically SNAT Auto Map, ensures that the BIG-IP replaces the client's source IP with its own internal self-IP before sending the request to the server. This forces the server to send the response back to the BIG-IP, allowing the BIG-IP to complete the transaction and deliver the content to the user.


NEW QUESTION # 42
An organization reports slow performance accessing an Intranet website. All employees use a single proxy IP.
What should the BIG-IP Administrator do?

  • A. Change Default Persistence to cookie
  • B. Change Fallback Persistence to source_addr
  • C. Change Load Balancing to Least Connections
  • D. Change Source Address to proxy IP

Answer: A

Explanation:
When many users share one source IP, source-address persistence fails. Cookie persistence uniquely identifies clients at Layer 7.


NEW QUESTION # 43
Refer to the exhibit.

DNS queries from two internal DNS servers are being load-balanced to external DNS servers via a virtual server on a BIG-IP device. The DNS queries originate from:
192.168.10.100
192.168.10.200
and target:
192.168.2.150
All DNS queries destined for the external DNS servers fail.
Which property change should the BIG-IP Administrator make in the Virtual Server to resolve this issue?
(Choose one answer)

  • A. Source Address to 192.168.10.0/24
  • B. Type to Performance (HTTP)
  • C. Protocol to UDP
  • D. Protocol profile (Client) to DNS_OPTIMIZED

Answer: C

Explanation:
DNS traffic is primarily transported using UDP port 53. In the exhibit, the Virtual Server is configured with the Protocol set to TCP, which prevents standard DNS queries from being processed correctly. BIG-IP Virtual Servers must be configured with the correct Layer 4 protocol to match the application traffic they are handling.
According to the BIG-IP Administration: Data Plane Configuration documentation:
* The Protocol setting on a Virtual Server defines whether traffic is processed as TCP, UDP, or another supported transport protocol.
* Standard DNS queries and responses use UDP, while TCP is only required for DNS zone transfers (AXFR) or exceptionally large responses.
* When a DNS Virtual Server is incorrectly configured with TCP, UDP-based DNS queries are dropped, causing all requests to fail.
Why the other options are incorrect:
* A. Protocol profile (Client) to DNS_OPTIMIZEDA DNS profile enhances DNS functionality but does not correct an incorrect transport protocol configuration.
* B. Type to Performance (HTTP)Performance (HTTP) Virtual Servers are designed for HTTP traffic and are not suitable for DNS services.
* C. Source Address to 192.168.10.0/24The existing source IPs already fall within the allowed range, so this setting does not address the failure.
Correct Resolution:
Changing the Protocol to UDP aligns the Virtual Server with standard DNS transport requirements, allowing DNS queries to be successfully processed and load-balanced.


NEW QUESTION # 44
A virtual server is configured to offload SSL from a pool of backend servers. When users connect to the virtual server, they successfully establish an SSL connection but no content is displayed. A packet trace performed on the server shows that the server receives and responds to the request. What should a BIG-IP Administrator do to resolve the problem? (Choose one answer)

  • A. disable Server SSL profile
  • B. disable SNAT
  • C. enable SNAT
  • D. enable Server SSL profile

Answer: C

Explanation:
This scenario describes a classic case of asymmetric routing in a "one-arm" or non-gateway deployment.
When a BIG-IP system is configured for SSL offloading, the following traffic flow occurs:
* Client-Side: The client establishes a successful SSL/TLS handshake with the Virtual Server. This explains why the user can "successfully establish an SSL connection."
* Server-Side: The BIG-IP decrypts the traffic and forwards it as plain HTTP to the backend server. The packet trace confirms the server receives the HTTP GET request and responds with the content.
* The Routing Failure: By default, the BIG-IP system preserves the client's original source IP address. If the backend server's default gateway is not the BIG-IP system (or if the server is on the same subnet as the client), the server will attempt to send the response directly back to the client's IP address, bypassing the BIG-IP.

Since the response bypasses the BIG-IP, the BIG-IP connection eventually times out, and the client receives no data despite the server having sent it.
Solution (SNAT): Enabling Secure Network Address Translation (SNAT), specifically SNAT Auto Map, ensures that the BIG-IP replaces the client's source IP with its own internal self-IP before sending the request to the server. This forces the server to send the response back to the BIG-IP, allowing the BIG-IP to complete the transaction and deliver the content to the user.


NEW QUESTION # 45
A BIG-IP Administrator creates a new Virtual Server. The end user is unable to access the page. During troubleshooting, the administrator learns that the connection between the BIG-IP system and server is NOT set up correctly. What should the administrator do to solve this issue? (Choose one answer)

  • A. Set Address Translation to SNAT and have a self-IP configured in the same subnet as the servers
  • B. Set Address Translation to SNAT and configure a specific translation address
  • C. Disable Address Translation
  • D. Set Address Translation to Auto Map, configure a SNAT pool, and have pool members in the same subnet as the servers

Answer: A

Explanation:
The issue described is a classic symptom of asymmetric routing, which frequently occurs when the BIG-IP system and the back-end servers reside on the same subnet (often referred to as a "one-arm" deployment).
* The Routing Problem: By default, the BIG-IP system preserves the original client source IP address when forwarding traffic to a pool member. If the server is in the same subnet as the client or if the server's default gateway is not the BIG-IP, the server will attempt to send its response directly back to the client's IP address, bypassing the BIG-IP.
* Stateful Failure: Since the BIG-IP is a Full Proxy, it maintains a state table. Because the response packet never returns through the BIG-IP, the system cannot complete the three-way handshake or manage the application session, resulting in a connection failure for the user.
* The Solution (SNAT): Enabling Source Network Address Translation (SNAT) solves this by changing the source IP address of the request to an IP address owned by the BIG-IP (typically a self-IP).
* Requirement for Subnet Alignment: To ensure the server sends the response back to the BIG-IP, the translation address must be reachable. By using a self-IP configured in the same subnet as the servers, the BIG-IP ensures that the server sees the request coming from a local "neighbor." The server will then naturally send the response back to that self-IP, allowing the BIG-IP to translate the packet back and forward it to the client.
Why other options are incorrect:
* A: Disabling address translation would ensure the server-side traffic uses the client IP, making asymmetric routing inevitable in this scenario.
* B: This is technically contradictory; "Auto Map" specifically uses existing self-IPs and does not require or use a "SNAT pool" configuration.
* C: While using a specific translation address can work, it does not inherently guarantee the Layer 2
/Layer 3 reachability mentioned in the scenario as effectively as ensuring the self-IP is correctly placed in the server's subnet.


NEW QUESTION # 46
Due to a change in application requirements, a BIG-IP Administrator needs to modify the configuration of a Virtual Server to include a Fallback Persistence Profile.
Which persistence profile type should the BIG-IP Administrator use?

  • A. Source Address Affinity
  • B. Universal
  • C. Hash
  • D. SSL

Answer: A

Explanation:
Fallback persistence is used when the primary persistence method fails. Source Address Affinity is a Layer 4 persistence method and is fully supported as a fallback option for most virtual server types.


NEW QUESTION # 47
In a pool there are 2 pool members out of the 5 members that are older servers. The number of connections these can handle is less than the other 3 pool members. Which load balancing method would allow more traffic to be directed to the newer servers? (Choose one answer)

  • A. Global Availability
  • B. Least Connections (member)
  • C. Round Robin
  • D. Weighted Least Connections (member)

Answer: D

Explanation:
When a pool contains servers with heterogeneous hardware capabilities (differing CPU, RAM, or connection limits), a static load balancing method like Round Robin is ineffective because it distributes requests equally, regardless of the server's capacity. To optimize traffic distribution for newer, more powerful servers, a dynamic or weighted method is required.
Weighted Least Connections (member): This is the ideal method for this scenario. It combines two factors:
Least Connections: It first checks the current active connection count to ensure traffic goes to the least busy server.
Weight (Ratio): It allows the administrator to assign a "Ratio" value to each pool member. Newer servers can be assigned a higher ratio (e.g., 3) while older servers are assigned a lower ratio (e.g., 1). The BIG-IP system uses these weights to disproportionately favor the newer servers even when connection counts are similar.
Why other options are incorrect:
Global Availability: This is primarily a GSLB (Global Server Load Balancing) or specific LTM priority group concept where traffic is sent to the first available member in a list until it fails, then moves to the next. It does not load balance based on capacity.
Round Robin: This passes each new connection request to the next server in line, treating the old and new servers exactly the same.
Least Connections (member): While this sends traffic to the server with the fewest active connections, it assumes all servers are equal. If an old server and a new server both have 10 connections, they are treated as equally capable of taking the 11th, which is not true in this scenario.


NEW QUESTION # 48
A Virtual Server uses an iRule to send traffic to pool members depending on the URI. The BIG-IP Administrator needs to modify the pool member in the iRule.
Which event declaration does the BIG-IP Administrator need to change to accomplish this?

  • A. SERVER_CONNECTED
  • B. HTTP_REQUEST
  • C. CLIENT_ACCEPTED
  • D. HTTP_RESPONSE

Answer: B

Explanation:
URI-based traffic steering requires inspection of the HTTP request. BIG-IP processes HTTP headers and URIs in the HTTP_REQUEST event. Pool member selection based on URI must occur before the request is sent to the server, making HTTP_REQUEST the correct event.


NEW QUESTION # 49
In a pool there are 2 pool members (older servers) that can handle fewer connections than the other 3 newer servers.
Which load balancing method would allow more traffic to be directed to the newer servers? (Choose one answer)

  • A. Global Availability
  • B. Least Connections (member)
  • C. Round Robin
  • D. Weighted Least Connections (member)

Answer: D

Explanation:
This scenario requires unequal load distribution based on server capacity. The newer servers must receive more connections than the older ones, while still dynamically accounting for active connection counts.
According to BIG-IP Administration: Data Plane Configuration documentation:
* Weighted Least Connections (member) combines:
* Connection awareness (least connections)
* Administrator-defined weights (ratios) to reflect server capacity
* Pool members with higher weights receive proportionally more new connections than members with lower weights, even when using the same load balancing algorithm.
Why B is correct:
* Allows assigning higher weights to newer servers and lower weights to older servers
* Ensures smarter traffic distribution based on both capacity and real-time load Why the other options are incorrect:
* A. Global AvailabilityUsed for disaster recovery and site failover, not intra-pool load distribution.
* C. Round RobinDistributes connections evenly without considering server capacity.
* D. Least Connections (member)Balances only by current connection count and does not account for differences in server performance or capacity.
Correct Resolution:
Use Weighted Least Connections (member) and assign higher weights to newer servers so they receive more traffic while protecting older servers from overload.


NEW QUESTION # 50
Which Virtual Server type prevents the use of a default pool?

  • A. Performance (Layer 4)
  • B. Performance (HTTP)
  • C. Standard
  • D. Forwarding (IP)

Answer: D

Explanation:
Forwarding (IP) virtual servers forward traffic based on routing decisions and do not use pools or pool members.


NEW QUESTION # 51
All pool members are online. All other virtual server settings are at default.
What might alter the load balancing behavior? (Choose one answer)

  • A. Adding a persistence profile
  • B. Enabling a fallback host in the HTTP profile
  • C. Adding a OneConnect profile
  • D. Enabling SNAT automap

Answer: A

Explanation:
By default, BIG-IP load balancing algorithms (such as Round Robin) distribute connections evenly across all available pool members. However, persistence profiles override normal load balancing decisions by forcing subsequent connections from a client to be sent to the same pool member.
According to the BIG-IP Administration: Data Plane Configuration documentation:
Persistence creates a client-to-server mapping that is honored before load balancing algorithms are applied.
When persistence is enabled, BIG-IP may repeatedly select the same pool member even if others are available.
This directly alters load balancing behavior.
Why the other options are incorrect:
A . Adding a OneConnect profile
OneConnect optimizes server-side TCP connections but does not change which pool member is selected.
B . Enabling SNAT automap
SNAT affects source address translation, not pool member selection.
C . Enabling a fallback host in the HTTP profile
A fallback host is only used when no pool members are available.
Correct Resolution:
Adding a persistence profile alters load balancing behavior by maintaining client affinity to a specific pool member.


NEW QUESTION # 52
How will the BIG-IP system distribute the traffic based on the configuration below?
pool my_pool {
lb_mode fastest
min_active_members 2
member 10.12.10.7:80 priority 3
member 10.12.10.8:80 priority 3
member 10.12.10.9:80 priority 3
member 10.12.10.4:80 priority 2
member 10.12.10.5:80 priority 2
member 10.12.10.6:80 priority 2
member 10.12.10.1:80 priority 1
member 10.12.10.2:80 priority 1
member 10.12.10.3:80 priority 1
}
(Pick the 2 correct responses below)

  • A. Connections are distributed to all pool members with priority 2 if one pool member with priority 3 is down
  • B. Connections are first distributed to all pool members with priority 3 when all the pool members with priority 3 are available
  • C. If both the priority 1 group and the priority 2 group have fewer than two members available, traffic is directed to the priority 3 group
  • D. If both the priority 3 group and the priority 2 group have fewer than two members available, traffic is directed to the priority 1 group

Answer: B,D

Explanation:
The configuration provided utilizes Priority Group Activation in conjunction with the min_active_members setting. Priority groups allow an administrator to define primary servers and "backup" servers within the same pool. The BIG-IP prioritizes traffic based on the assigned priority number, with the highest number receiving traffic first.
In this specific configuration, the priority 3 group is the primary group. Therefore, connections are first distributed to all pool members with priority 3 as long as they are available. The system will continue to use only the priority 3 group unless the number of available members in that group falls below the min_active_members value, which is set to 2.
If the priority 3 group has fewer than two active members, the BIG-IP "activates" the next available priority group (priority 2) and distributes traffic among the remaining members of priority 3 and all members of priority 2. This cascading logic continues down the list. Consequently, if both the priority 3 group and the priority 2 group have fewer than two members available, traffic is directed to the priority 1 group. This ensures that even in a multi-server failure scenario, the system has a last-resort group of servers to handle the traffic.
Option D is incorrect because if only one member of priority 3 goes down, there are still two members active (10.12.10.8 and 10.12.10.9). Since 2 is not less than the min_active_members threshold of 2, the priority 2 group will not yet be activated. Option B is incorrect because traffic flows from high priority to low priority, not the other way around.


NEW QUESTION # 53
The BIG-IP Administrator is investigating if better TCP performance is possible for a virtual server. Which built-in profile should be tried first?

  • A. f5-tcp-progressive
  • B. f5-tcp-mobile
  • C. f5-tcp-legacy
  • D. f5-tcp-wan

Answer: A

Explanation:
F5 provides several pre-configured (built-in) TCP profiles designed to optimize traffic for different network conditions. When an administrator is looking to improve general performance but does not have a specific, narrow use case (like strictly mobile or strictly long-haul WAN), the f5-tcp-progressive profile is the recommended starting point.
The f5-tcp-progressive profile is designed as a modern, high-performance replacement for the older default TCP settings. It incorporates several advanced congestion control algorithms and buffer management techniques that allow it to adapt dynamically to varying network latencies and packet loss scenarios. Unlike f5-tcp-legacy (Option A), which uses older, less efficient stacks, the progressive profile leverages modern TMM (Traffic Management Microkernel) optimizations.
While f5-tcp-mobile (Option B) is highly effective for high-loss cellular networks and f5-tcp-wan (Option D) is optimized for high-latency long-distance links, they can sometimes be too aggressive or poorly suited for standard campus or data center environments. The f5-tcp-progressive profile acts as a "best-of-all-worlds" template that typically provides an immediate performance boost for most web applications by improving window scaling and fast-retransmit behavior. Therefore, it is the procedural "first step" in TCP performance tuning before moving to more specialized, niche profiles.


NEW QUESTION # 54
The BIG-IP Administrator has to provide encrypted communication between users and the virtual server they access. Multiple hostnames are configured in DNS with the same IP address.
Which profile type and setting in the profile should be used? (Choose one answer)

  • A. Server SSL, Server Name
  • B. Server SSL, Client Name
  • C. Client SSL, Server Name
  • D. Client SSL, Client Name

Answer: C

Explanation:
When multiple hostnames resolve to the same IP address and encrypted communication is required, the BIG-IP must be able to present the correct SSL certificate based on the hostname requested by the client. This is accomplished using Server Name Indication (SNI).
According to BIG-IP Administration: Data Plane Configuration documentation:
SNI is a client-side TLS extension, where the client includes the requested hostname during the SSL handshake.
BIG-IP evaluates this hostname using the Client SSL profile, not the Server SSL profile.
The "Server Name" setting in the Client SSL profile enables BIG-IP to select the appropriate SSL certificate for the requested hostname.
Why option C is correct:
Client SSL profile handles inbound (client-side) encryption.
Server Name enables SNI-based certificate selection when multiple DNS names share the same virtual server IP.
Why the other options are incorrect:
A . Client SSL, Client Name
There is no Client SSL setting called Client Name for SNI certificate selection.
B . Server SSL, Server Name
Server SSL is used for encryption between BIG-IP and backend servers, not for client-side hostname identification.
D . Server SSL, Client Name
Server SSL does not process client-requested hostnames during TLS negotiation.
Correct Resolution:
Configure a Client SSL profile and enable the Server Name (SNI) setting to support multiple encrypted hostnames on the same virtual server IP.


NEW QUESTION # 55
An LTM device has a virtual server mapped to www.f5.com with a pool assigned. The objects are defined as follows: Virtual server: Destination 192.168.245.100:443 netmask 255.255.255.0. Persistence: Source address persistence netmask 255.0.0.0. SNAT: Automap. Profiles: HTTP/TCP. How should the BIG-IP Administrator modify the persistence profile so that each unique IP address creates a persistence record?

  • A. netmask 255.255.255.0
  • B. netmask 0.0.0.0
  • C. netmask 255.255.0.0
  • D. netmask 255.255.255.255

Answer: D

Explanation:
Source Address Affinity (Persistence) works by tracking the source IP address of incoming packets to ensure a client stays connected to the same backend server. The "netmask" setting within the persistence profile determines the "granularity" of this tracking. A netmask tells the BIG-IP how many bits of the source IP address to ignore when creating the persistence record. For example, the current setting of 255.0.0.0 (a /8 mask) means the BIG-IP only looks at the first octet of the IP; this results in all users from the same large Class A network (e.g., everyone from 10.0.0.0 to 10.255.255.255) being persisted to the exact same server, which can lead to severe load imbalance.
To ensure that each unique IP address creates its own individual persistence record, the administrator must set the netmask to 255.255.255.255 (for IPv4). This is a "host mask" or /32, which instructs the BIG-IP to evaluate all 32 bits of the client's source IP address. With this setting, 10.1.1.1 and 10.1.1.2 will be treated as distinct entities and can be load balanced to different servers, each maintaining their own "stickiness". While Option A (255.255.255.0) would group users by their local subnet, only the full 255.255.255.255 mask satisfies the requirement for true unique-IP persistence. This configuration is standard for internet-facing applications where users arrive from diverse locations and the administrator wants to maintain the most granular and balanced distribution of traffic possible.


NEW QUESTION # 56
The BIG-IP Administrator has to provide encrypted communication between the users and the virtual server they access. Multiple hostnames are configured in DNS with the same IP address. Which profile type and setting in the profile should be used? (Choose one answer)

  • A. Server SSL, Server Name
  • B. Server SSL, Client Name
  • C. Client SSL, Server Name
  • D. Client SSL, Client Name

Answer: C

Explanation:
To provide encrypted communication between users and a virtual server, the BIG-IP system acts as a transparent SSL/TLS proxy. The administrative configuration required for this is a Client SSL profile.
When multiple hostnames (FQDNs) are associated with a single IP address, the system must determine which SSL certificate to present to the client during the initial TLS handshake. This is achieved using an extension of the TLS protocol called Server Name Indication (SNI).
The configuration logic is as follows:
* Profile Type: The Client SSL profile is responsible for terminating the SSL connection from the client (the user) to the BIG-IP system.
* The Setting: Within the Client SSL profile (under the "Advanced" view), there is a field specifically called Server Name. By entering the specific hostname (e.g., www.example.com) in this field, the BIG- IP system can match the hostname requested by the client in the ClientHello message to the correct profile.
* Implementation: The administrator typically creates multiple Client SSL profiles-one for each hostname-and assigns them all to the same virtual server. One of these profiles must be designated as the Default SSL Profile for SNI to handle requests where the client does not provide a hostname or provides one that does not match any specific profile.
By using the Client SSL profile and the Server Name setting, the BIG-IP system ensures that each user receives the correct certificate for the specific site they are trying to reach, even though all sites share a single virtual server IP.


NEW QUESTION # 57
A BIG-IP Administrator uses backend servers to host multiple services per server. There are multiple virtual servers and pools defined, referencing the same backend servers.
Which load balancing algorithm is most appropriate to have an equal number of connections on each backend server? (Choose one answer)

  • A. Least Connections (node)
  • B. Least Connections (member)
  • C. Predictive (node)
  • D. Predictive (member)

Answer: A

Explanation:
In this scenario, each backend node (server) hosts multiple services and is referenced by multiple pools and virtual servers. The goal is to ensure an equal number of total connections per backend server, regardless of how many pool members (services/ports) exist on that server.
According to the BIG-IP Administration: Data Plane Configuration documentation:
Least Connections (node) tracks the total number of active connections to a node across all pool members and services.
This algorithm ensures load distribution is balanced at the server level, not just at the individual service (member) level.
It is specifically recommended when:
Multiple pool members exist on the same backend server
Multiple virtual servers reference the same backend servers
Why the other options are incorrect:
B . Predictive (member)
Predictive algorithms are advanced and traffic-pattern based, but they operate at the member level and do not guarantee equal connections per server.
C . Least Connections (member)
This balances connections per pool member, which can overload a server hosting multiple members while still appearing "balanced" per member.
D . Predictive (node)
Although node-aware, predictive algorithms are less deterministic and not the best choice when strict equality of connections is required.
Correct Resolution:
Using Least Connections (node) ensures that each backend server carries an equal connection load across all services and pools.


NEW QUESTION # 58
A BIG-IP Administrator is setting up a new BIG-IP device. The network administrator reports that the interface has an incompatible media speed. The BIG-IP Administrator needs to change this setting manually.
From which location should the BIG-IP Administrator perform this task?

  • A. On the Front Console
  • B. In the Configuration Utility, System > Configuration
  • C. In the Configuration Utility, Network > Interface
  • D. In the TMOS Shell Command line

Answer: C

Explanation:
Standard BIG-IP administration dictates that hardware-level physical attributes are managed within the Network section of the configuration. When a network switch and a BIG-IP fail to successfully negotiate speed and duplex settings (Auto-Negotiation), it can result in CRC errors, late collisions, or a total lack of link. To resolve this manually, the administrator must navigate to the Configuration Utility (GUI) and go to Network > Interfaces.
Within the Interfaces list, the administrator can select the specific physical port (e.g., 1.1 or 1.2) and modify its properties. By default, the media speed is set to "Auto," but the drop-down menu allows for manual selection of specific speeds (e.g., 100Mb/s, 1Gb/s, 10Gb/s) and duplex settings (Full or Half). While these changes can also be made via the TMOS Shell (TMSH) (Option B) using the modify net interface command, the question asks for the standard location, which in most administrative contexts refers to the primary GUI path. System > Configuration (Option D) is used for global device settings like NTP, DNS, and licensing, not for interface-specific physical layer parameters. The Front Console (Option A), referring to the LCD panel on physical appliances, is primarily used for initial management IP setup and viewing system alerts, but does not provide the granular interface configuration required for media speed adjustments.


NEW QUESTION # 59
During a high-demand event, the BIG-IP Administrator needs to limit the number of new connections per second to a Virtual Server.
What should be applied?

  • A. OneConnect profile
  • B. HTTP Compression profile
  • C. Connection Limit
  • D. Connection Rate Limit

Answer: D

Explanation:
Connection rate limits restrict how many new connections are accepted per second, protecting application resources.


NEW QUESTION # 60
For a given Virtual Server, the BIG-IP must perform SSL Offload and negotiate secure communication over TLSv1.2 only. What should the BIG-IP Administrator do to meet this requirement?

  • A. Configure a custom SSL Profile (Client) and select no TLSv1 in the options list
  • B. Configure a custom SSL Profile (Server) and select no TLSv1 in the options list
  • C. Configure a custom SSL Profile (Server) with a custom TLSv1.2 cipher string
  • D. Configure a custom SSL Profile (Client) with a custom TLSv1.2 cipher string

Answer: D

Explanation:
To fulfill the requirement of "SSL Offload" limited to "TLSv1.2 only," the administrator must focus on the client-side of the connection. SSL Offload means the BIG-IP terminates the encrypted connection from the user, processes the traffic (often as plain text internally), and optionally sends it to the backend. The profile responsible for this termination and the initial negotiation with the client's browser is the Client SSL Profile.
A custom Client SSL Profile must be created because the default clientssl profile typically allows a broad range of protocols for compatibility (including TLS 1.0, 1.1, and 1.2). To restrict communication specifically to TLS 1.2, the administrator modifies the Ciphers string within the profile. Using a string such as DEFAULT:!SSLv3:!TLSv1:!TLSv1.1 or specifically defining TLSv1.2-only suites ensures that the BIG-IP will reject any handshake attempts from older, less secure protocols.
Server SSL Profiles (Options B and C) are used for the encryption between the BIG-IP and the backend nodes, which is not what is requested here. Simply selecting "no TLSv1" in an options list (Option D) is insufficient and often refers to older versions of the software; the modern and standard way to control protocol negotiation on a BIG-IP is through the precise application of Cipher Strings within the Client SSL profile. This ensures compliance with security standards like PCI-DSS while providing the offloading benefits to the backend infrastructure.
