• Question 174:

  An incoming frame is received by a transparent bridge. If the destination address of the frame is not present in the database, the bridge:

  A. Discard the frame
  B. Send out the frame on all interfaces, except on the interface where the frame originate
  C. Put the destination MAC address in the table
  D. Broadcast the frame on all interfaces

• Question 175:

  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. Any Pingable IP address from Telnet session in Site Bravo SWT 1, No static route needed to allow access to other nodes.
  B. 192.168.1.101/24, Yes in Node E, local subnet pointed to 192.168.1.254.
  C. 192.168.1.152/24, No Static route needed to allow access to other nodes.
  D. 192.168.1.14/24, No Static route needed to allow access to other nodes.
  C. 192.168.1.152/24, No Static route needed to allow access to other nodes.

• Question 177:
