You are working as a senior network technician at Certkiller .com. A trainee asks you in what way
Network Address Translation (NAT) provides additional security for users behind a gateway router.
What will your answer be?

A.
NAT blocks users on the public Internet from initiating connections to computers on a local
network.

B.
NAT blocks users on a local network from initiating connections to computers on the public
Internet.

C.
NAT prevents access to the Internet during non-working hours.

D.
NAT limits users from accessing web sites on a blocked site list.

Explanation:
As NAT uses private, non-routable addresses you are unable to target the client from another
subnet than the one being NATed. The only way to reach a client behind a NATing device is by
setting up port forwarding or address forwarding to the inside network.
