In Active/Standby pseudowires a failed pseudowire has recovered. Under what circumstances will the active pseudowire revert to the previously failed link?

  1. It will always revert to the previously failed link.
  2. It will never revert to the previously failed link.
  3. It will revert if the precedence of the previously failed link is set to 0 or "primary".
  4. It will revert if the precedence of the previously failed link is lower than the currently active link

Answer(s): C

Assume there are two VPLS services configured on the MDU. How could load-balancing be achieved when using Active/Standby pseudowires?

  1. This cannot be done.
  2. Each VPLS will use the same pair of SDP's with the same endpoint configured with the option "load-balancing 2".
  3. Each VPLS will need their own pair of spoke-SDP's configured. The spoke-sdp's that are to be active should be configured with the option "precedence primary".
  4. Under the end-point configuration, enable load-balancing 2 and the MDU will load balance automatically.

Answer(s): C

Assume PE-1 has a mesh-sdp configured to every PE node in both Metro networks. What could be done to prevent the bandwidth replication between Metro 1 and Metro 2?

  1. PE-1 must be configured with mesh-SDPs to every node receiving the multicast traffic. There is no way to reduce the replication or bandwidth.
  2. PE nodes in Metro 1 could be configured with mesh-SDPs. PE nodes in Metro 2 would be configured with mesh-SDPs. However, the connection between Metro networks (PE-2 to PE-6) can be configured with a spoke-sdp. This would reduce the replication and bandwidth used on the link between Metro networks. This also reduces the replication required by PE-1.
  3. PE-1 can be configured with spoke-SDPs to every PE node in both Metro networks. This will reduce the bandwidth and replication within the network.
  4. PE nodes in Metro 1 could be configured with spoke-SDPs. PE nodes in Metro 2 would be configured with spoke-SDPs. However, the connection between Metro networks (PE-2 to PE-6) can be configured with a mesh-sdp. This would reduce the replication and bandwidth used on the link between Metro networks. This also reduces the replication required by PE-1.

Answer(s): B



Why are provisioning requirements a factor that influence VPLS design? (Choose 2)

  1. Adding or removing a node may require several network touches.
  2. Adding or removing a SAP may require several network touches.
  3. Adding or removing a service may require several network touches.
  4. Adding or removing an Epipe may require several network touches.
  5. Provisioning is a factor for all Ethernet services.

Answer(s): A,C
