Correct Answer: B

Question 7

An Alcatel-Lucent 7750 SR receives a route via an IS-IS LSP with internal reach ability, and receives the same route via an OSPF type 5 LSA. If al protocol preferences are default, which route will be installed in the route table?

A. The route learned via the OSPF type 5 LSA will be installed.

Question 11

Click on the exhibit.

An OSPFv3 router is attached to a non-OSPF domain that includes networks 2001:DB8:8::/64.2001 .DB8:9::/64 and 2001 :DB8:A::/64. Other routers in the OSPF domain see the prefix 2001,DB8:8::/64, but not the other two prefixes.
What could cause this?

A. The router is not configured as an asbr.

B. The prefix list should be 2001:DB8:8::/46

C. The export policy is not applied to OSPFv3.

D. The router is not configured as an NSSA.

Correct Answer: B

Question 12

Which of the following is correct?

A. A reference-bandwidth is configured on the router but wide-metrics is not.

B. Neither a reference-bandwidth nor wide-metrics is configured on the router.

C. The router is correctly configured.

D. Wide-metrics is configured on the router but a reference-bandwidth is not.

Correct Answer: A

Question 13

Click on the exhibit.

A. It's not possible to say how many broadcast or point-to-point links there are.

B. There are five broadcast links and there are five point-to-point links.

C. There are five broadcast links and there are no point-to-point links.

D. There are five broadcast links. It's not possible to say how many point-to-point links there are.

Correct Answer: D

Question 14

Which of the following best describes the actions taken by an IS-IS router after it receives an LSP on a broadcast interface that is newer than the one in its database?

A. The router sends a copy of the LSP from its database to its neighbor.

B. The router updates its database with the LSP and acknowledges it with a PSNP.

C. The router updates its database with the LSP, acknowledges the LSP with a PSNP and floods a copy to its other neighbors.

D. The router updates its database with the LSP and floods a copy to its other neighbors.

Correct Answer: D

Question 15

Which of the following statements regarding OSPF routing updates on a multi-access network segment is true?

A. In multi-access networks, a DR and BDR are elected only if the subnet masks on the router interfaces are less than /30

B. In multi-access networks, a DR and BDR are elected only if there are more than two routers connected to the network segment.

C. In multi-access networks, a DR and BDR are elected. The DR sends link-state advertisements describing the network.

D. In multi-access networks, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.
