  A. They allow a VPLS to scale more easily.

  B. They use mesh SDPs to connect smaller VPLSes together.

  C. They allow a service to span multiple metro networks.

  D. They simplify the configuration required when adding new PEs.

  Correct Answer: B

• Question 285:

  By default, what does the Nokia 7750 SR do when a frame with an unknown destination address is received in a VPLS?

  A. It drops the frame.

  B. It floods the frame to all PEs participating in the service.

  C. It sends a destination unreachable message back to the originating host.

  D. It sends the frame to the closest neighbor.

  Correct Answer: B

• Question 286:

  A customer has sites on three different Nokia 7750 SRs. The customer requires a fully-meshed VPLS. Which of the following is TRUE?

  A. Each router requires 1 SDP.

  B. Each router requires 2 SDPs.

  C. Each router requires 3 SDPs.

• Question 287:

  Click the exhibit. This output is from router R4. Service 333 is a VPLS. Why might the peer 10.10.10.1 have the same value for IngLbl and EgrLbl?

  A. The labels are of local significance only, so other routers can use the same value.

  B. 10.10.10.1 has yet to send its own unique label.

  C. Router R4 is using the same tunnel to send and receive to 10.10.10.1.

  D. The service on 10.10.10.1 is down, so it is rejecting packets.

  Correct Answer: A

• Question 288:

  A. The frame is dropped.

  B. The frame's outer tag is changed to match the SAP, and it is accepted.

  C. The frames outer tag is dropped, and the frame is accepted.

  A. sap 1/1/1

  B. sap 1/1/1:*

  C. sap 1/1/1:0 D. sap 1/1/1:1

  Correct Answer: D

• Question 290:

  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).

  B. To the customer, the PE appears as a native Frame Relay UNI (User Network Interface).

  C. Multiple Frame Relay circuits can be mapped to a single F-pipe service on the Nokia 7750 SR.

  D. The MPLS control word is required because the Frame Relay header is not encapsulated in the frame.

  Correct Answer: C
