  C. The router updates the information in its LSDB with the information received from its neighbor.
  D. The router sends a link-state request to its neighbor.
  E. The router takes no action.
  A. The router sends a link-state update to its neighbor.

• Question 233:

  On an Alcatel-Lucent 7750 SR, what is the recommended approach for making sure that MTUs between a VPLS and its spoke IES termination match?

  A. Set the service MTU of the VPLS to match the IES MTU.
  B. Set the ip-mtu of the IES to match the service MTU of the VPLS.
  C. Set the SDP MTU of the IES to match the SDP MTU of the VPLS.
  D. Set the MTU of the IES's network port to match the service MTU of the VPLS.
  B. Set the ip-mtu of the IES to match the service MTU of the VPLS.

• Question 235:

  Click on the exhibit.

  

  All links are of equal cost. A CSPF-enabled LSP is configured on R1 to R6. Its fully loose primary path is configured with an "include green" statement and the fully loose secondary path is configured with an "include red" statement. Which paths will be taken by this LSP?

  A. No primary path is established. The secondary path will take R1-R2-R4-R6.
  B. The primary path will take R1-R3-R5-R6. The secondary path will take R1-R2-R4-R6.
  C. The primary path will take R1-R2-R4-R6. No secondary path is established.
  D. The primary path will take R1-R2-R4-R6. The secondary path will take R1-R3-R5-R6.
  C. The primary path will take R1-R2-R4-R6. No secondary path is established.

• Question 236:

  Which of the following about F-pipes is FALSE?

  A. F-pipes use SAPs in the form of port: DLCI (e.g. 1/2/3:65).

  C. Multiple Frame Relay circuits can be mapped to a single F-pipe service on the Alcatel- Lucent 7750 SR.
  D. The MPLS control word is required because the Frame Relay header is not encapsulated in the frame.
  C. Multiple Frame Relay circuits can be mapped to a single F-pipe service on the Alcatel- Lucent 7750 SR.
