• Question 591:

  Click on the exhibit button below. Assume the following:

  

  -The protected path is R1-R2-R3-R6.

  -Fast reroute one-to-one protection is enabled.

  If the original LSP already has two labels, and router R2 has failed, how many labels will there be in packets on the detour path?

  A. 1
  B. 2
  C. 3
  D. 4
  B. 2

• Question 592:

  What can you deduce from the show command on router R6?

  A. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment. The DR for this segment would be the router with router ID 10.10.10.5.
  B. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment; however, this command does not indicate whether 10.10.10.3 or 10.10.10.5 is the DR or BDR.
  C. The router R6 interface is in a multi-access segment. It is the BDR, which is why it is not adjacent to the other routers.
  D. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment. The DR for this segment would be the router with router ID 10.10.10.3.
  B. The router R6 interface is in a multi-access segment. It is neither the DR nor the BDR for the segment; however, this command does not indicate whether 10.10.10.3 or 10.10.10.5 is the DR or BDR.

• Question 593:

  Consider a network that has four PE routers. If a customer wants a VPLS that has sites on only three of the PEs, how many mesh SDPs need to be configured for this service?

  A. 3
  B. 4
  C. 6
  D. 12
  C. 6

  B. The value of the E bit in the options field does not have to match.
  C. The value of the Hello interval does not have to match.
  D. The value of the network mask does not have to match.
  E. The area ID, the E bit value, the Hello interval and network mask must all match.
  E. The area ID, the E bit value, the Hello interval and network mask must all match.

  B. An export policy is required on CE1 to advertise local routes to PEL
  C. An export policy is required to advertise routes between the PE routers.
  D. No export policy is required on PE2 or CE2 due to the static routes.

• Question 598:

  What labels are encapsulated in the tunnels used by a 6PE deployment?

  A. The inner label is the IPv4 Explicit Null. The outer label is the MPLS transport label.
  B. The inner label is an MPLS transport label. The outer label is the IPv4 Explicit Null.
  C. The inner label is the IPv6 Explicit Null. The outer label is an MPLS transport label.
