You are trying to establish an IS-IS Level 1 adjacency over ge-1/0/1 between R1 and R7 without impacting the
other IS-IS adjacencies on R1.
Which configuration change would satisfy this requirement?

What are two characteristics of L2 circuits? (Choose two.)

The exhibit shows the partial configurations of PE1 and PE2. PE2 is unable to forward VPN data to PE1.
What should be configured to solve this problem?

An L2VPN (draft-kompella-mpls-l2vpn) is established between two PE routers to provide connectivity between
two customer sites.
Which two statements related to this deployment are true? (Choose two.)

Referring to the exhibit, you control AS 24652. You are asked to ensure that traffic destined to the
23.56.83.0/24 network from ISP 4 takes the most optimum path through ISP 3. ISP 1 should be used as a
backup for this traffic flow.
Which two actions would accomplish this task? (Choose two.)

To reduce the size of OSPF Area 100, you configure the area with the no-summaries parameter. After
committing this configuration change, you notice that an OSPF router in a remote area is no longer receiving
Type 5 LSAs from an ASBR in Area 100.
Which statement is true in this scenario?

In a carrier-of-carrier VPN model, which type of network layer reachability information is used for the MP-BGP
signaling between CE and PE routers?

Which two statements are associated with any-source multicast? (Choose two.)

You have configured an OSPF stub area. The routes in the stub area require external reachability.
Which statement explains how OSPF meets this requirement?
