A fully loose LSP MtoR6" is enabled with FRR protection. All links have the same cost. After the link between R2 and R4 goes down, FRR protection repairs the LSP and traffic traverses on R1-R2-R7-R8-R4-R6. By default, which of the following about this LSP on an Alcatel-Lucent 7750 SR is FALSE?

A.

The LSP will switch to R1-R3-R5-R6 after the resignal timer expires.

B.

The old primary path and its detours are torn down after the new primary path is established.

C.

CSPF must be enabled to find a more optimal path.

D.

The traffic is switched to R1-R3-R5-R6 in an MBB fashion.

Which of the following best describes an IES?

A.

Layer 3 direct Internet access service.

Layer 2 point-to-point service.

C.

Layer 2 multipoint-to-multipoint service.

D.

Layer 3 IP multipoint-to-multipoint VPN service.

Which of the following about label modes on the Alcatel-Lucent 7750 SR is FALSE?

A.

RSVP uses downstream on demand label distribution mode.

B.

LDP uses conservative label retention mode.

C.

LDP advertises label mappings to all peers for which it might be a next-hop for a given FEC.

D.

RSVP distributes a label mapping for a FEC when it has been requested to do so.

The time router R2 takes to find out a number of RSVP Hello messages have been missed.

C.

The time router R2 takes to send a PATH Tear message to the head-end router.
