• Question 263:

  Click the Exhibit button to view the topology.

  

  Host 1 and Host 2 are on Ethernet LANs in different buildings. A serial line is installed between two Cisco routers using Cisco HDLC serial line encapsulation. Routers A and B are configured to route IP traffic. Host 1 sends a packet to Host 2. A line hit on the serial line causes an error in the packet. When this is detected, the retransmission is sent by:

  A. Host 1
  B. Host2
  C. Router A
  D. RouterB
  E. Protocol analyzer
  A. Host 1

• Question 264:

  BGP can implement a policy of 'Route Dampening' to control route instability. What statement about route dampening is NOT correct?

  A. A numeric penalty is applied to a route each time it flaps.
  B. The penalty is exponentially decayed according to parameters, such as halF. life-time.
  C. The history of unstable routes is forwarded back to the sender to control future updates.
  D. The route is eventually suppressed based on a configurable 'suppress limit'.
  C. The history of unstable routes is forwarded back to the sender to control future updates.

• Question 265:

  A. The router will not forward this packet, since it is destined for the 0 subnet.
  B. The router will forward the packet through 172.31.116.65, since it has the lowest metric.
  C. The router will forward the packet through 10.1.1.1.
  D. The router will forward the packet through 172.31.116.65, since it has the lowest administrative distance.
  E. The router will forward the packet through 192.168.1.4.
  C. The router will forward the packet through 10.1.1.1.

  D. The source address is at or near the beginning of the frame.
  E. The data is compressed in the middle of the frame.
  A. The destination address is at or near the beginning of the frame.

• Question 268:

  Every time a typing mistake is made at the exec prompt of a router, the message from the router indicates a lookup is being performed. Also, there is a waiting period of several seconds before the next command can be typed. Can this behavior be changed?
