Refer to the topology and router configuration shown in the graphic.

A host on the LAN is accessing an FTP server across the Internet.
Which of the following addresses could appear as a source address for the packets forwarded by the router to the destination server?

A.
10.10.0.1

B.
10.10.0.2

C.
199.99.9.33

D.
199.99.9.57

E.
200.2.2.17

F.
200.2.2.18

Explanation:
Using NAT we can translate the Source or Destination Address. In our example all source address from the 10.10.00 0.0.0.255 network will be translated to an IP address form the 199.99.9.40-62 pool, making 199.99.9.57 correct.
