Question # 12

Which of the following best describes constraint-based routing?

A mechanism that implements opaque LSAs.

A mechanism that computes routes based on defined user requirements.

A mechanism that allows the IGP shortest path to be used.

A mechanism that allows RSVP or LDP signaling to use a route other than the IGP best route to establish a LSP.

Question # 13

If an LSP's loose primary path includes the statement "include green" and "exclude red;" how does CSPF choose the LSP's path?

CSPF chooses a link that is a member of both administrative groups

CSPF chooses only those links that are NOT members of the green admin group

CSPF prunes the green links and uses these links for the secondary path

CSPF signals the LSP path over the green links only, and prunes all other links

Question # 14

Router R3 signals an LSP, reserving 1Gbps bandwidth on a 10Gbps link. RSVP configuration limits reservable bandwidth to 20 percent on the egress interface. Which of the following statements is true?

The egress RSVP interface has 80 percent bandwidth unreserved.

LSPs can reserve an additional 9.9 Gbps bandwidth on this RSVP interface.

The head end reserves 100Mbps for the LSP

The egress RSVP interface has 1 Gbps bandwidth unreserved.
