QUESTION 38
Click the exhibit button.

Which of the following would correctly configure routers R2, R3, and R4?

Option A

Option B

Option C

Option D

QUESTION 39
Click the exhibit button.

Router R2 advertises the network 192.168.3.0/24 to router R1 via OSPF. A route policy has been constructed to discard the route on router R1; however, it is not working. What is the problem?

The prefix list reject should be “192.168.3.0/16 exact”.

Router R1 should be configured as an OSPF “asbr”.

The policy “reject” should be set for import rather than export.

The policy was likely not “committed” after creation.

This is not possible because OSPF cannot use import policies.

QUESTION 40

A static route is created using the command “static-route 2.3.4.0/24 next-hop 1.2.3.4”. What is the correct traceroute command to test this static route on a Nokia 7750 SR?

traceroute 2.3.4.1

traceroute 2.3.4.0/24 next-hop 1.2.3.4

traceroute next-hop 1.2.3.4
