  D. The device will detect the port change and revert to discovery mode.

  Correct Answer: D

• Question 64:

  What option is available when using PBB to reduce the amount of required VPLS services?

  A. The Alcatel-Lucent 7750 SR supports 1:1 mapping of I-VPLS services to B-VPLS services.

  B. The Alcatel-Lucent 7750 SR supports 1:1 andM:1 mapping of l-VPLS services to B- VPLS services.

  C. The Alcatel-Lucent 7750 SR supports the mapping of multiple, standard VPLS services to B- VPLS services.

  D. The Alcatel-Lucent 7750 SR supports the mapping of multiple, standard VPLS services to l- VPLS services.

  Correct Answer: B

• Question 65:

  What type of SDP cannot be configured in an l-VPLS?

  A. Mesh-sdp

  B. Spoke-sdp

  C. MPLS

  D. GRE

  Correct Answer: A

• Question 66:

  Which of the following describes the setting of the l-SID on the Alcatel-Lucent 7750 SR?

  A. The I-SID is set to 0 by default and is only used for interop purposes. The receiving PE uses the service label to determine the I-VPLS.

  B. There is no default value. The I-SID must always be explicitly configured

  C. The I-SID is set to the service-id, unless the service-id is larger than a 24 bit value. In this case the ISID must be explicitly configured.

  D. The I-SID is always set to the service-id by default.

  Correct Answer: C

  A. PE-A must replicate the frame to all devices participating in the VPLS

  B. PE-A must replicate the frame to all PEs within Metro A

  C. PE-A must replicate the frame to all devices in the Metro A

  D. All of the above

  Correct Answer: B
