A network engineer is asked to configure a “site-to-site” IPsec VPN tunnel. One of the last things that the
engineer does is to configure an access list (access-list 1 permit any) along with the command ip nat inside
source list 1 int s0/0 overload. Which functions do the two commands serve in this scenario?
A. The command access-list 1 defines interesting traffic that is allowed through the tunnel.
B. The command ip nat inside source list 1 int s0/0 overload disables “many-to-one” access for all devices on a defined segment to share a single IP address upon exiting the external interface.
C. The command access-list 1 permit any defines only one machine that is allowed through the tunnel.
D. The command ip nat inside source list 1 int s0/0 overload provides “many-to-one” access for all devices on a defined segment to share a single IP address upon exiting the external interface.

Correct Answer: D
