4A0-116 Exam Training Practice Tests (Nokia Segment Routing)]

Question 1

Based on the exhibit, which of the following is a viable option for the Path Computation Element (PCE) to obtain all the necessary topology and traffic-engineering information from the network, so that it can calculate LSP paths on behalf of the PE routers?

A. Establishing a BGP session using the BGP-LS address family with router R3 B. Establishing an IGP adjacency with router R2 C. Establishing IGP adjacencies with routers R1 and R2 D. Establishing BGP sessions using the BGP-LS address family with routers R3 and R4

Correct Answer: D

Question 2

Question 3

Based upon the exhibit, which of the following statements regarding the configuration is FALSE?

A. Traffic engineering information will only be advertised for the interfaces that have both MPLS and RSVP enabled. B. Adjacency-SID labels will not be advertised as they have not been defined under the physical interfaces. C. The Node-SID assigned to this router is the second label in the defined range. D. Traffic engineering has been enabled on this router.

Correct Answer: A

Question 4

Which of the following statements about a Segment Routing SID is FALSE?

Question 5

Which of the following statements about Segment Routing tunnels is FALSE?

A. For a Segment Routing tunnel, an intermediate router will always forward the packet based on the best IGP path. B. A Segment Routing tunnel can be defined by a combination of Node-SIDs and Adjacency-SIDs. C. A Segment Routing tunnel can be defined by multiple Node-SIDs. D. A Segment Routing tunnel defined by a Node-SID uses the shortest IGP Path.
