• Question 258:

  -- Exhibit ?

  

  -- Exhibit -

  A packet with a source MAC address of 00:26:88:02:74:23 enters your EX Series switch on port ge-0/0/2.

  Assuming the filter in the exhibit has been applied to interface ge-0/0/2, which action will apply?

  A. It discards and counts the packet.

  B. It rejects and counts the packet.

  C. It accepts the packet.

  D. It discards the packet.

  Correct Answer: A

• Question 259:

  What are two characteristics of an OSPF link-state update? (Choose two.)

  A. A link-state update can be sent directly after an adjacency is formed.

  B. A link-state update can only contain a single link-state advertisement (LSA).

  C. A link-state update is sent in response to a link-state request.

  D. A link-state update is used to determine which router is in charge of the database exchange.

  Correct Answer: AC

• Question 260:

  A company has four routers connected as follows:

  PEER ----- (A -- B -- C -- D)

  Router A has an external BGP peer. IBGP peering sessions exist between A-B, B-C, C-D, and A-D. The company is running an IGP for all internal segments and does not use static routes. Router D cannot use BGP paths from Router A in its

  routing table.

  What are two reasons why this is occurring? (Choose two.)

  A. The routes have an unreachable next-hop address.

  B. BGP synchronization is disabled by default.

  C. Router A is not configured to use next-hop self.

  D. The TTL exceeds 1, preventing BGP routing updates from being sent between Router A and Router D.

  Correct Answer: AC
