• Question 411:

  Which of the following statements regarding LDP reliability is false?

  A. By default, the policy for manually configuring LDP FRR specifies that backup routes with 32-bit addresses should trigger the setup of a backup LDP L5P.
  B. Synchronization between LDP and IGP requires suppression of IGP route advertisement to achieve consistent LDP and IGP.
  C. LDP FRR can generate an LSP as the backup of the primary L5P based on Label Mapping messages that are not from the optimal next hop. LDP FRR establishes forwarding entries for the backup LSP.
  D. LDP Graceful Restart (GR) leverages the separation of the forwarding plane and control plane by MPLS to ensure uninterrupted traffic transmission during a protocol restart or active/standby switchover.
  D. LDP Graceful Restart (GR) leverages the separation of the forwarding plane and control plane by MPLS to ensure uninterrupted traffic transmission during a protocol restart or active/standby switchover.

• Question 412:

  Router HW1 functions as an MPLS LSR router on the carrier's network. The router receives a labelled packet, but the label entry does not exist in the router's LFIB. Given this information, how will the router process the packet?

  A. Router HW1 discards the packet.
  B. Router HW1 uses the default label to forward the packet.
  C. Router HW1 removes the label, searches the FIB, and uses the destination IP address to forward the packet.
  D. Router HW1 uses LDP to create an LSP and creates a path in its LFIB for the label carried in the packet.
  A. Router HW1 discards the packet.

• Question 413:
