Question 51

Click on the exhibit button below. If CE1 and PE1 use BGP to exchange routing information and CE2 and PE2 use static routing to forward traffic to and from the VPRN, which of the following statements is considered TRUE?

  1. An export policy is required on PE1 to advertise routes to CE1.
  2. An export policy is not required on PE2 to advertise routes to CE2.
  3. An export policy is not required to advertise routes between PE routers
  4. All of the above statements are true
  5. All of the above statements are false

Question 52

Which of the following statements is TRUE concerning a VPRN data plane flow?

  1. A data packet will receive a service label at the CE and a transport label at the ingress PE.
  2. A data packet intended for a remote CE will have its service label swapped at each P router along the path towards the egress PE.
  3. At the egress PE, the transport label will be popped and the data packet forwarded with the service label.
  4. The service label is popped by the remote CE. The unlabeled packet is forwarded based on the longest match lookup algorithm in the VRF.
  5. All of the above statements are false.
  6. All of the above statements are true.
