  LSP "toR8-5" requests fast reroute protection on the primary loose path. What could be done to remove the Failure Code shown?

  A. CSPF must be enabled at head-end on fast reroute protected loose path LSPs

  B. Fast reroute must first be enabled on the downstream routers.

  C. CSPF must be enabled on all downstream loose hop routers.

  D. Global revertive path optimization must be enabled so the path will be re-optimized around a failed node.

  Correct Answer: A

• Question 192:

  Router R4 originates 500 RSVP signaled LSPs with default hello and refresh timer settings If the only downstream communication fails (link is operationally UP), how long will RSVP wait before it declares the RSVP sessions down?

  A. 3000ms

  B. 9000ms

  C. 30000ms

  D. 120000ms

  Correct Answer: B

• Question 193:

  A targeted-LDP session may exist between directly connected or non-directly connected devices

  A. TRUE

  B. FALSE

  Correct Answer: A

• Question 194:

  On a point-to-point link, two directly connected routers set different interface hello timeout values. Router R1 uses 15 seconds, while router R2 uses 30 seconds. What happens to the LDP adjacency?

  A. The adjacency forms with the lower timeout value

  B. The "show router Idp session" command output displays the adjacency in state "init"

  C. The adjacency forms with the higher timeout value

  D. The adjacency times out after 30 seconds

  Correct Answer: A

• Question 195:

  How many bits of the MPLS header are used for the label field?

  C. 24

  D. 25

  E. 32

  Correct Answer: B

• Question 196:

  Which of the following best describes constraint-based routing?

  A. A mechanism that implements opaque LSAs.

  B. A mechanism that computes routes based on defined user requirements.

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

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

  Correct Answer: B

• Question 197:

  Which fields in this output uniquely identify the RSVP session belonging to a single LSP? (Choose three)

  A. Tunnel ID

• Question 198:

  Which of the following statements is true of an established LDP session?

  A. It uses a UDP connection with an arbitrary port number.

  B. It uses a UDP connection with well known port number 646.

  C. It uses a TCP connection with an arbitrary port number.

  D. It uses a TCP connection with well known port number 646.

  Correct Answer: D

• Question 199:

  Click on the exhibit button below.

  

  Given the configuration shown, how much of a link's 100Mbps reservable bandwidth can an LSP access when configured for class-type 0 and priority 1?

  A. 10Mbps

  B. 20Mbps

  C. 30Mpbs

  D. 60Mbps

  E. 70Mbps

  Correct Answer: E

• Question 200:

  Which of the following statements regarding LDP-over-RSVP are true? (Choose two)

  A. Targeted sessions must exist between all routers in the tunnel's path.

  B. Each LDP interface must be configured to support LDP tunneling.

  C. LDP prefixes resolve to an RSVP LSP, rather than to a physical egress interface.

  D. RSVP LSPs must exist between each PE-ABR pair, or ABR-ABR pair in each area.

  Correct Answer: CD
