Cisco 200-120 Practice Questions

200-120 Question 15


Refer to exhibit:



Which destination addresses will be used by Host A to send data to Host C? (Choose two.)


A.  the IP address of Switch 1
B.  the MAC address of Switch 1
C.  the IP address of Host C
D.  the MAC address of Host C
E.  the IP address of the router's E0 interface
F.  the MAC address of the router's E0 interface


Correct Answer: C,F
Explanation/Reference:

While transferring data through many different networks, the source and destination IP addresses are not changed. Only the sour ce and destination MAC addresses are changed. So in this case Host A will use the IP address of Host C and the MAC address of E0 interface to send dat a. When the router receives this data, it replaces the source MAC address with it own E1 interface's MAC address and replaces the destination MAC address with H ost C's MAC address before sending to Host C.
