B. not-so stubby area

C. virtual link

D. Type 10 LSA

With which two elements is a VRF table populated? (Choose two.)

Referring to the exhibit, what must be added to the existing configuration to ensure that per-prefix load balancing occurs?

A. multihop

B. keep all

C. multipath

D. family inet unicast

You are asked to deploy VPLS in your network as a new service for several customers, and you must identify the configuration and provisioning requirements for your customers. Which two statements are correct in this scenario? (Choose two.)

A. CE interfaces facing the service prowler must be Ethernet interfaces.

B. VLAN IDs defined on CE interfaces must be the same on both ends unless otherwise negotiated.

C. CE interfaces facing the service provider must be Layer 3 interfaces.

D. PE interfaces facing the core must have VPLS encapsulation enabled.

You want to reject routes from any BGP peers that have prepended their AS path.

What is the correct as-path regex that would allow you to accomplish this task?

A. 65001.*

B. .{2,}

C. (65001|65001|65001)

D. .{0,1}

The route shown in the exhibit is being advertised to the EBGP peer and displays a next hop of itself. However, you do not have a next-hop self policy configured. What would cause this behavior?

A. The IBGP peers have a next-hop self policy, which the router is exporting to the EBGP neighbors.

B. The set protocols bgp path-selection as-path-ignore is not set and must be added so the next-hop attribute will propagate from the peer.

C. The set protocols bgp accept-remote-next hop is not set and must be added so the next- hop attribute will propagate from the peer.

D. The next-hop attribute was modified by default when it was advertised to the EBGP peer, without applying a policy.

How is a BGP Layer 2 VPN prefix formed by a PE?

A. by combining the route distinguisher and vrf-target, in that order

B. by combining the route distinguisher, remote site identifier, and site identifier, in that order

C. by combining the route distinguisher, site identifier, and remote site identifier, in that order

D. by combining the vrf-target and route distinguisher, in that order

You have the multi-area OSPF network design shown in the exhibit.

Which path will traffic from R1 transit to reach R4 if the R2-R4 link fails?

A. R1-R2-R5-R3-R4

B. R1-R2-R3-R5-R4

C. R1-R2-R3-R4

D. R1-R2-R5-R4

Routers R1, R2, and R3 have set protocols isis interface all configured and no other set protocols isis configuration.

Referring to the exhibit, which two statements are true? (Choose two.)

A. The R2-R3 link will form a Level 1 and Level 2 adjacency.

B. The R1-to-R2 link will only form a Level 2 adjacency.

C. The R1-to-R2 link will form a Level 1 and Level 2 adjacency.

D. The R2-R3 link will only form a Level 1 adjacency.

Which two statements are correct regarding site IDs and circuit IDs in a VPLS routing instance? (Choose two.)

B. In an LDP VPLS routing instance, the vpls-id parameters must match in all locations.

C. In a BGP VPLS routing instance, the site-id parameters must be different in each location.

D. In a BGP VPLS routing instance, the site-id parameters must match in all locations.

You are asked to configure PIM-SM in your network. Your implementation must allow for load sharing between redundant RPs and, should an RP failure occur, the RP failover time should be minimized.

Which two configuration tasks are required in this scenario? (Choose two.)

A. Configure MSDP peering sessions between the routers designated as RPs.

B. Configure the shared anycast address on the RPs as the primary address on the loopback interface.

C. On the routers designated as RPs, configure the shared anycast address on the loopback interface.

D. Configure at least two static RPs and bundle them in an RP redundancy group under [edit protocols pim].
