R1 and R2 have a Level 1 IS-IS adjacency. R2 participates in both Level 1 and Level 2, and is receiving routes from a Level 2 neighbor. A policy on R2 has been created to leak routes to Level 1, but R1 is not receiving the routes.

Referring to the exhibit, what is the solution on R2?

A. The policy must be applied as an export policy at the interface level.

B. The policy must be changed to include from protocol isis.

C. The policy must be changed to specify from level 2 and to level 1.

D. The policy must be applied as an import policy.

A. For Level 1 adjacencies, area IDs must be the same

B. For Level 2 adjacencies area IDs must be the same

C. The IS-IS levels configured on the interfaces must be the same

D. The IS-IS levels on the interfaces can be different

Your area border router (ABR) receives type 1.2 and 5 link-state advertisements (LSAs) from a non-backbone area.

What would the ABR do with the information learned from the non-backbone area?

A. The ABR will generate type 2 and 3 LSAs and flood type 5 LSAs to the backbone area

B. The ABR will generate only type 3 LSAs and flood only type 5 LSAs to the backbone area

C. The ABR will generate type 3 and 4 LSAs. And flood type 5 LSAs to the backbone area

D. The ABR will generate only type 4 LSAs and flood only type 5 LSAs to the backbone area

Which two problems occur when increasing numbers of users are added to an Ethernet LAN with no switches present? (Choose two.)

A. There is a greater chance for collisions to occur

B. The MAC table sizes increase

C. Some devices will not see certain traffic

D. There is unnecessary consumption of network bandwidth

You have just configured IPv6 in your network. A packet arrives on your router that exceeds the MTU size. How will an IPv6 router respond?

B. The packet is kept intact and not fragmented.

C. The packet is dropped.

D. The packet is fragmented based on extension headers.

Your network runs RSTP and includes a LAN segment shared by two MX Series devices. The two MX Series devices sharing this LAN segment each have two connections on the shared segment.

B. The MX Series device with the highest-cost path to the root bridge is selected as a designated bridge for the shared segment.

C. The port on the selected MX Series device with the highest port ID is selected as the designated port.

D. The MX Series device with the least-cost path to the root bridge is selected as the designated bridge for the shared segment.

Your area boarder router (ABR) receives type 1, 2, and 5 link-state advertisements (LSAs) from a nonbackbone area. What would the ABR do with the information learned from the nonbackbone area?
