• Question 293:

  How does a VPRN service avoid the problem of overlapping IP addresses from different customers?

  A. You cannot have overlapping IP addresses. Customers must change their IP address assignment.
  B. Each VPRN service maintains a separate VPN routing and forwarding instance to separate customer routing information. This allows for overlapping addresses.
  C. A VPRN ignores IP addressing information and uses MAC addressing instead, which are always unique.
  D. A VPRN translates customer IP addresses to a private addressing scheme administered by the service provider.
  B. Each VPRN service maintains a separate VPN routing and forwarding instance to separate customer routing information. This allows for overlapping addresses.

• Question 294:

  Which of the MPLS routers is responsible for pushing new labels for LSP A and LSP B?

  

  A. Router R1 pushes labels for both LSP A and LSP B.
  B. Router R4 pushes labels for both LSP A and LSP B.
  C. Router R1 pushes labels for LSP A, while router R4 pushes labels for LSP B.
  D. Router R4 pushes labels for LSP A, while router R1 pushes labels for LSP B.
  C. Router R1 pushes labels for LSP A, while router R4 pushes labels for LSP B.

• Question 295:

  C. The router ID is used to uniquely identify every OSPF router.
  D. On the Nokia 7750 SR, the router ID is set to the highest logical IP address if router-id is not explicitly set.
  B. The system address is used as the router ID if router-id is not set.
  C. The router ID is used to uniquely identify every OSPF router.

• Question 298:

  Choose two true statements that characterize Distance Vector Routing?
