問題2
Based upon the exhibit, which of the following statements regarding the configuration is FALSE?

A. Traffic engineering has been enabled on this router.

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 information will only be advertised for the interfaces that have both MPLS and RSVP enabled.

正確答案: D

問題3
In the context of a network that includes a Path Computation Element (PCE), what is a PCC-initiated LSP?

A. An LSP that needs to be explicitly configured on the head-end router.

B. An LSP for which the initial path is calculated by the head-end router.

C. An LSP whose existence and state are reported to the PCE.

D. An LSP for which the path repairs and re-optimizations must be triggered by the head-end router.

問題4
Which of the following is NOT an advantage of using a PCE for the computation of TE-constrained LSP paths, as compared to using CSPF locally on the PE router?

A. The ability to create cross-area TE-constrained LSP paths

B. The ability to create LSP paths with bandwidth reservation

C. The ability to create LSPs with primary and secondary paths

D. The ability to ensure that some LSP paths are disjoint

正確答案: B

問題5
The exhibit presents packets being transmitted inside an LSP's multi-segment primary path going from router R1 to router R8. The LSP also has a standby secondary path, and Seamless-BFD has been enabled on the primary path. The link between routers R1 and R2 fails, and fast re-route (FRR) is triggered. As a result, router R1 forwards the packets to router R3 and adds the proper FRR encapsulation to reach which router?

A. To reach router R8, which is the tail-end of the LSP.

B. To reach router R4, which is the tail-end of the active segment.

C. To reach router R5, which is the shortest way to go back to the original path.

D. To reach router R2, which is the LSP's intended next-hop.

正確答案: C
