• Question 333:

  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

  A. It is necessary to configure a NSAP address.
  B. It is not possible to perform both IP and CLNS routing with the same process.
  C. IP address and subnet information is carried in the TLVfield on the L-1/L-1 LSPs.
  D. Dual IS-IS does not support VLSM information.
  A. It is necessary to configure a NSAP address.
  C. IP address and subnet information is carried in the TLVfield on the L-1/L-1 LSPs.

• Question 336:

  A. An over-subscribed Frame Relay switch will cause some packet loss.
  B. There are problems in the use of OSPF Authentication.
  C. There is an incorrect selection of the Designated Router.
  D. There is an incorrect DLCI assigned on a point-to-point sub-interface.
  C. There is an incorrect selection of the Designated Router.
