The FastEthernet interface fa0/0 of router 1 is wrongly configured.

Refer to the exhibit. Which list refers only to end devices? D,E,F,G

Refer to the exhibit. Host A sends a frame with the destination MAC address as FFFF.FFFF.FFFF. What action will the switch take for this frame? It will drop the frame.
It will send the frame back to host A.
It will send the frame to all hosts except host A. 
It will forward the frame to the default gateway.

Refer to the exhibit. RouterB is configured properly. The Ethernet interface Fa0/0 of RouterA is configured with the use of the commands that are shown. However, a ping from the Fa0/0 interface of RouterA to the Fa0/0 interface of RouterB is unsuccessful. What action should be taken on RouterA to solve this problem? Use the description command on the FastEthernet interface Fa0/0. Configure the clock rate of the FastEthernet interface Fa0/0. Use the no shutdown command on the FastEthernet interface Fa0/0.  Reboot the router.
