  A. It tests the IGP reachability of the far-end IP address of an SDP.

  B. It tests that the MTU settings of a service are correct.

  C. It tests in-band, uni-directional or round-trip connectivity of SDPs.

  A. 0

  B. 1

  C. 2

  D. 3

  Correct Answer: B

• Question 18:

  Which of the following best describes the flooding of traffic on a PE when unknown traffic is received on a mesh SDP?

  A. Traffic is flooded to all SAPs in the service.

  B. Traffic is flooded to all SAPs and spoke SDPs in the service.

  C. Traffic is flooded to all SAPs and mesh SDPs in the service.

  D. Traffic is flooded to all SAPs, spoke SDPs, and mesh SDPs in the service.

  E. The traffic is not flooded.

  Correct Answer: B

• Question 19:

  FRF.5 is a standard that describes which of the following requirements?

  A. ATM to Frame Relay translation.

  B. Frame Relay to Ethernet translation.

  C. ATM tunneling over a Frame Relay core network.

  D. Frame Relay tunneling over an ATM core network.

  Correct Answer: D

• Question 20:

  Assuming CE1 exports its system address using BGP, is a routing policy required on PE1 to advertise CE1's system address to PE2?

  

  A. Yes. A routing policy is required to advertise routes between PE routers in a VPRN regardless of the CE-PE routing.

  B. Yes. A routing policy is required in this case because BGP is used as the PE-CE routing protocol.

  C. No, a routing policy is not required: By default, the Nokia 7750 SR will advertise all VPRN routes between PE routers.

  D. No, a routing policy is not required on PE1, but an import policy is required on PE2.

  Correct Answer: C
