NEW QUESTION 34
Refer to the exhibit.
An engineer is trying to generate a summary route in OSPF for network 10.0.0.0/8, but the summary route does not show up in the routing table. Why is the summary route missing?
- A. There is no route for a subnet inside 10.0.0.0/8, so the summary route is not generated.
- B. The summary route is not visible on this router, but it is visible on other OSPF routers in the same area.
- C. The summary route is visible only in the OSPF database, not in the routing table.
- D. The summary-address command is used only for summarizing prefixes between areas.
Answer: A
Explanation:
Explanation
The summary-address is only used to create aggregate addresses for OSPF at an autonomous system boundary.
It means this command should only be used on the ASBR when you are trying to summarize externally redistributed routes from another protocol domain or you have a NSSA area. But a requirement to create a summarized route is:
The ASBR compares the summary route's range of addresses with all routes redistributed into OSPF on that ASBR to find any subordinate subnets (subnets that sit inside the summary route range). If at least one subordinate subnet exists, the ASBR advertises the summary route.
NEW QUESTION 35
Refer to Exhibit:
AS 111 wanted to use AS 200 as the preferred path for 172.20.5.0/24 and AS 100 as the backup. After the configuration, AS 100 is not used for any other routes. Whichconfiguration resolves the issue?
- A. route-map SETLP permit 10
match ip address prefix-list PLIST1
set local-preference 110
route-map SETLP permit 20 - B. router bgp 111
no neighbor 192.168.10.1 route-map SETLP in
neighbor 192.168.20.2 route-map SETLP in - C. router bgp 111
no neighbor 192.169.10.1 route-map SETLP in
neighbor 192.168.10.1 route-map SETLP out - D. route-map SETLP permit 10
match ip address prefix-list PLIST1
set local-preference 99
route-map SETLP permit 20
Answer: D
Explanation:
There is an implicit deny all at the end of any route-map so all other traffic that does not match 172.20.5.0/24 would be dropped. Therefore we have to add a permitsequence at the end of the route-map to allow other traffic.
The default value of Local Preference is 100 and higher value is preferred so we have to set the local preference of AS100 lower than that of AS200.
NEW QUESTION 36

Same Answer is already updated below:
HTTP and HTTPs run on TCP port 80 and 443, respectively and we have to remember them.
Syslog runs on UDP port 514 while NTP runs on UDP port 123 so if we remember them we can find out the matching answers easily. But maybe there is some typos in this question as 2001:d88:800:200c::c/126 only ranges from 2001:d88:800:200c:0:0:0:c to 2001:d88:800:200c:0:0:0:f (4 hosts in total). It does not cover host 2001:0D88:0800:200c::1f. Same for 2001:D88:800:200c::e/126, which also ranges from
2001:d88:800:200c:0:0:0:c to 2001:d88:800:200c:0:0:0:f and does not cover host 2001:0D88:0800:200c::1c

Refer to the exhibit.
The administrator can see the traps for the failed login attempts, but cannot see the traps of successful login attempts. What command is needed to resolve the issue?
- A. Configure logging history 3
- B. Configure logging history 5
- C. Configure logging history 4
- D. Configure logging history 2
Answer: B
Explanation:
Explanation
By default, the maximum severity sent as a syslog trap is warning. That is why you see syslog traps for login failures. Since a login success is severity 5 (notifications), those syslog messages will not be converted to traps. To fix this, configure:
Note:
The syntax of login block is:
login block-for seconds attempts tries within seconds

NEW QUESTION 45
Drag and drop the packet types from the left onto the correct descriptions on the right.
Answer:
Explanation:
Explanation
Unlike legacy network technologies such as ISDN, Frame Relay, and ATM that defined separate data and control channels, IP carries all packets within a single pipe. Thus, IP network devices such as routers and switches must be able to distinguish between data plane, control plane, and management plane packets to treat each packet appropriately.From an IP traffic plane perspective, packets may be divided into four distinct, logical groups:1. Data plane packets - End-station, user-generated packets that are always forwarded by network devices to other end-station devices. From the perspective of the network device, data plane packets always have a transit destination IP address and can be handled by normal, destination IP address-based forwarding processes.2. Control plane packets - Network device generated or received packets that are used for the creation and operation of the network itself. From the perspective of the network device, control plane packets always have a receive destination IP address and are handled by the CPU in the network device route processor. Examples include protocols such as ARP, BGP, OSPF, and other protocols that glue the network together.3. Management plane packets - Network device generated or received packets, or management station generated or received packets that are used to manage the network. From the perspective of the network device, management plane packets always have a receive destination IP address and are handled by the CPU in the network device route processor. Examples include protocols such as Telnet, Secure Shell (SSH), TFTP, SNMP, FTP, NTP, and other protocols used to manage the device and/or network.4. Services plane packets - A special case of data plane packets, services plane packets are also user-generated packets that are also forwarded by network devices to other end-station devices, but that require high-touch handling by the network device (above and beyond normal, destination IP address-based forwarding) to forward the packet. Examples of high-touch handling include such functions as GRE encapsulation, QoS, MPLS VPNs, and SSL/IPsec encryption/decryption, etc. From the perspective of the network device, services plane packets may have a transit destination IP address, or may have a receive destination IP address (for example, in the case of a VPN tunnel endpoint).

Refer to Exhibit.
A network administrator has successfully configured DMVPN topology between a hub and two spoke routers. Which two configuration commands should establish direct communications between spoke 1 and spoke 2 without going through the hub? (Choose two).
- A. At the hub router, configure the ip nhrp shortcut command.
- B. At the spoke routers, configure the ip nhrp spoke-tunnel command.
- C. At the hub router, configure ip nhrp redirect the command
- D. At the spoke routers, configure the ip nhrp shortcut command.
- E. At the hub router, configure tne Ip nhrp spoke-tunnel command
Answer: C,D
Explanation:
To configure Spoke to Spoke communication we can configure DMVPN Phase II or Phase III. But in Phase II, the first few packets would go through Hub. In order tototally ignore the hub, we have to use DMVPN Phase III:
DMVPN Phase III is same as Phase 2 but removes some restrictions and complexities of Phase 2. Also allows greater variety of DMVPN network designs we use:+ ip nhrp redirect in hub: tells the initiator spoke to look for a better path to the destination spoke than through the Hub. Upon receiving the NHRP redirect message thespokes communicate with each other over the hub and they have their NHRP replies for the NHRP Resolution Requests that they sent out.+ ip nhrp shortcut in spokes: overwrite the CEF table on the spoke. It basically overrides the next-hop value for a remote spoke network from the default initial hubtunnel IP address to the NHRP resolved remote spoke tunnel IP address)
