BPE-1 requires a full mesh of RSVP-TE LSPs to all routers in area 1.

CABR-1 requires T-LDP sessions to all ABRs in area 0.

DPE-1 requires fast reroute enabled on all RSVP-TE LSPs.

Answer : B

Question 2

Answer : B

Question 6

An LSP is configured with one-to-one FRR and node protection on a Alcatel-Lucent 7750 SR. Which of the following is FALSE?

AEach PLR signals a protection tunnel that avoids the downstream node.

BA single protection tunnel can protect all LSPs that go through the same hop.

CA link protection tunnel is signaled if a node protection tunnel cannot be established.

DProtection tunnels used in this LSP are also detour tunnels.

Answer : B

Question 7

Which of the following about Fast Reroute link protection tunnels is FALSE?

ALink protection tunnels are established if a router is unable to establish node protection tunnels.

BLink protection tunnels are only requested for a primary LSP path.

CLink protection tunnels can be created for both one-to-one or facility Fast Reroute.

DLink protection tunnels detour around a failed next downstream router.
