Refer to the exhibit. What will Router1 do when it receives the data frame shown? (Choose three.)
 

A. Router1 will strip off the source MAC address and replace it with the MAC address 0000.0c36.6965.

B. Router1 will strip off the source IP address and replace it with the IP address 192.168.40.1.

C. Router1 will strip off the destination MAC address and replace it with the MAC address 0000.0c07.4320.

D. Router1 will strip off the destination IP address and replace it with the IP address of 192.168.40.1.

E. Router1 will forward the data packet out interface FastEthernet0/1.

F. Router1 will forward the data packet out interface FastEthernet0/2.




 

Suggested Answer: ACF

The router will decapsulate the frame, thus removing the source and destination MAC addresses. It will consult its routing table to work out on which interface to send the packet which is going to 192.168.40.5: interface FastEthernet0/2. The router will then encapsulate the packet into a new frame with its own MAC address as the source MAC address and the MAC address of 192.168.40.5 as the destination MAC address.
Looking at the ARP table, the MAC address for 192.168.40.5 is 0000.0c07.4320 (the one which has been dynamically learned and has age 9 minutes). So what is the routers MAC address on this link? The ARP table shows a static entry (no age) for 192.168.40.1 which is 0000.0c36.6965. As it is static, we can conclude that these are the routers IP and MAC address.
