Answer : D

Question 4

Click on the exhibit.

An LDP-over-RSVP tunnel is established between routers R1 and R6. There is a VPN service running between routers R1 and R6. Which of the following is TRUE?

ARouter R4 swaps both the RSVP-TE LSP label and LDP transport label received with new labels,

BRouter R4 swaps the VPN service label received with a new label.

CRouter R4 uses the same RSVP-TE LSP label as the one received from router R3.

DRouter R4 uses the same LDP transport label as the one received from router R3.

Answer : A

Question 5

Which of the following about MPLS shortcuts for IGP on an Alcatel-Lucent 7750 SR is FALSE?

AAn IGP route takes priority over a transport tunnel.

BBoth LDP and RSVP-TE based tunnels can be used.

CMPLS tunnels can be used to resolve the prefixes learned via IGP

Question 6

Which of the following devices receives labeled packets from the MPLS domain, removes the MPLS header, and forwards unlabeled packets outside the MPLS domain?

AP router

BLSR

CeLER

DiLER

Answer : C

Question 7

All links have 1Gbps unreserved bandwidth initially and all LSPs have the least-fill feature enabled. After the two LSPs have been signaled as shown, two new LSPs are configured. LSP-3 is signaled first with 600Mbps reserved. LSP-4 is signaled after with 800Mbps reserved. All LSPs have the same setup and hold priorities. Which paths will CSPF choose for LSP-3 and LSP-4?

ALSP-3 takes R1-R3-R5-R6 and LSP-4 takes R1-R2-R4-R6.

BLSP-3 takes R1-R2-R4-R6 and LSP-4 takes R1-R3-R5-R6.

CLSP-3 takes R1-R3-R5-R6 and LSP-4 has no available path.

DLSP-3 takes R1-R2-R4-R6 and LSP-4 has no available path.
