Question 16

Refer to the exhibit. A network operator wants to expand the segment routing global block in upcoming maintenance. The operator must ensure that the changes to the segment routing global block have no adverse impacts on the prefix-sid associated with the loopback0 interface used within the OSPF domain. Which command can the operator use to enforce R2 to have a strict prefix-sid assignment to loopback0? A. B. C. D.

Question 17

Refer to the exhibit. Router 1 is a core ABR in a Cisco Unified MPLS environment. All of the router 1 BGP peers are established, but traffic between customers is failing. Which BGP configuration must be added to the configuration?

  1. It must be configured for graceful restart
  2. It must be configured with a route reflector
  3. It must be configured with send labels
  4. It must be configured with PIC edge

Question 18

What can be used to determine a path from the head-end to a tail-end router when implementing SR-TE with a head-end, with little information on the network topology?

  1. traffic controller
  2. path computation engine
  3. tail-end router
  4. SNMP server

Question 19

Refer to the exhibit. R1 is directly connected to R2 and R3. R1 is in BGP AS 123, R2 is in BGP AS 2, and R3 is in BGP AS 3. Assume that there is no connectivity issue between R1, R2 and R1, R3. Which result between BGP peers R1, R2 and R1, R3 is true?

  1. The BGP session does not come up between R1 and R2 and between R1 and R3.
  2. The BGP session comes up between R1 and R2 and between R1 and R3.
  3. The BGP session comes up between R1 and R3, but not between R1 and R2.
  4. The BGP session comes up between R1 and R2, but not between R1 and R3.

Question 20

Refer to the exhibit. Router 1 has established an SR-TE tunnel with router 2. Which statement describes this configuration?

  1. Router 1 has a list of labels used to explicitly lay out a path to router 2.
  2. Router 1 and router 2 have a bidirectional tunnel set up with dynamic path selection.
  3. Router 1 is the head-end tunnel and has dynamically chosen a path to router 2.
  4. Router 2 is the head-end tunnel and has explicitly set a path to router 1.
