QUESTION
Refer to the exhibit.

The customer has reported an issue about eBGP loading. Currently the AS 100 eBGP links have an average outbound load of 65% and 20% respectively. On further investigation, traffic from 10.10.24.0 accounts for 45%, and 10.10.25.0 and 10.10.32.0 accounts for 20% each of the outbound load. The customer wants to spread the load between the two eBGP links more evenly. The BGP attributes are currently set at their default values. If you are located at AS 100 and want to influence how AS 100 sends traffic to AS 200, what BGP attribute would you configure to cause AS 100 outbound traffic to load the eBGP links more evenly?

A. On router A, set the default local-preference to 50.
B. On router B, set the default metric to 150.
C. On router B, configure a route map for 10.10.25.0/24 that sets the local preference to 150.
D. On router B, set the default local-preference to 150.

Correct Answer: C

QUESTION 177
Refer to the exhibit.

There are two eBGP links between AS100 and AS200. Currently the router A to router E link has an average inbound load of 65% and the router B to router F link has an average inbound load of 20%. After further investigation, it is found that traffic to the 10.10.1.16/28 subnet is using 45% of the bandwidth on the A to router E link and traffic to the 10.10.1.32/28 subnet is using 20% of the bandwidth on the A to router E link. Traffic to the 10.10.1.48/28 subnet is using 20% of the bandwidth on the B to router F link. If you want to influence how AS200 sends traffic to AS100, which two commands would you configure in AS100 to influence AS200 to use the eBGP links more evenly? (Choose two.)

A. neighbor 192.168.30.2 route-map as_50 out

B. neighbor 192.168.20.2 route-map as_50 out

C. route-map as_50 permit 10
match ip address 50
set metric 150
access-list 50 permit 10.10.1.16 0.0.0.240

D. route-map as_50 permit 10
match ip address 50
set metric 150
access-list 50 permit 10.10.1.32 0.0.0.240

Correct Answer: BC

QUESTION 178
Refer to the exhibit.

AS 65500 is running OSPF as its IGP and has two eBGP connections to the Internet provider AS 65501. The provider requires that you advertise all of the prefixes in AS 65500 to the provider as a single 192.168.12.0/22 route. Currently only Routers A and B are able to reach the Internet. Which of the following additions to the configuration will solve this issue?

A. RouterA(config)#ip cef
B. RouterA(config)# ip route 192.168.12.0 255.255.252.0 null 0
C. RouterA(config-router)#ebgp multihop 1
D. RouterA(config-router)#redistribute ospf 1
E. RouterA(config-router)#neighbor 192.168.14.253 next-hop-self
F. RouterA(config-router)#neighbor 192.168.14.253 local-as 65500

Correct Answer: B

QUESTION 179
Which BGP command provides the router ID, local preference, next hop, and BGP path in its output?

A. show ip route bgp
B. show ip bgp
C. show ip bgp neighbors
D. show ip bgp summary

Correct Answer: B

QUESTION 180
Refer to the exhibit.

For the accompanying router output, which of the following statements describes the state that neighbor 172.16.254.3 is in?

A. BGP can exchange routing information in this state.
B. The router will not accept connections from the peer.
C. The router is listening on its server port for connection requests from the peer.
D. The router has sent out an active TCP connection request to the peer.
