• Question 818:

  5. Which of the following is TRUE?

  A. The matching outer tag is removed, and the frame is forwarded.
  B. The inner tag is removed, and the frame is forwarded.

• Question 819:

  Click the exhibit button A. The route policy should be applied as in import policy

  

  The 192 168 3.0/24 network is learned on router R1 via IS-IS Given the OSPF configuration shown, and assuming that the OSPF adjacency between routers R1 and R3 is up, why is the 192 168.3.0/24 route not in router R3's route table? (Choose two)

  B. The no-redistribute-external command is used on router R1
  C. The route policy is incorrect. It should say "from protocol ISIS" rather than "from protocol direct".
  D. It is not possible to be an ASBR and an NSSA. The ASBR configuration should be removed.
  E. The interface between routers R1 and R3 needs to be in OSPF area 0 rather than OSPF area 1 because a backbone area must always exist.
  B. The no-redistribute-external command is used on router R1
  C. The route policy is incorrect. It should say "from protocol ISIS" rather than "from protocol direct".

• Question 820:

  How does an IS-IS router acknowledge the receipt of an IS-IS LSP on a point-to-point link?

  A. They are explicitly acknowledged by sending a CSNP to the sender identifying the LSP.
  B. They are implicitly acknowledged as a part of the link-state database synchronization and maintenance procedures.
  C. They are explicitly acknowledged by sending a PSNP to the sender identifying the LSP.
  D. They are implicitly acknowledged by the DIS multicast of CSNPs.
  C. They are explicitly acknowledged by sending a PSNP to the sender identifying the LSP.
