Configure the nexthop core router as a BGP peer.

Questions # 49:

Which of the following about CSPF is TRUE?

Options:

The tail-end router performs the CSPF calculation for an LSP.

CSPF calculations are always performed on RSVP-TE based LSPs.

The head-end router performs the CSPF calculation for an LSP.

Each downstream router performs its own CSPF calculation for an LSP.

Questions # 50:

The outer label will be exchanged for a new label.

All labels will be exchanged for one new label.

All labels will be exchanged for an equal number of new labels.

Questions # 52:

Which of the following statements is FALSE regarding SAPs?

Options:

VPWS: SAPs can be defined on Ethernet, POS, Sonet/SDH, or TDM channels.

VPWS: Two SAPs are defined for a service that originates and terminates on the same Alcatel-Lucent 7750 SR

VPLS: More than two SAPs can be defined in a service.

VPWS: SAPs are associated with an IP interface.

Questions # 53:

Facility fast reroute with node protection is enabled for an LSP, which of the following is FALSE?

Options:

Each PLR signals a bypass tunnel that avoids the next-hop downstream router.

When a failure occurs, the PLR pushs an additional label onto the label stack.

No bypass tunnel is established if the PLR cannot provide node protection.

The head-end router sets the local protection desired flag in the session attribute object.
