Why would a hacker be disappointed once she figured out that the network she is wanting to attack is using NAT?

A.
Internal addresses are hidden.

B.
Internal computers have another layer of firewall protection.

C.
There is only one entry to the network.

D.
NAT is harder to compromise than most firewalls.

Explanation:
NAT is not a firewall technology. And just because NAT is being used
does not mean that there is only one entry point to a network. NAT maps private
address to public addresses. All packets leaving the network will have the address
of the NAT device, so a hacker cannot see the internal addresses.
