Answer: A

Explanation:

This is a one-to-one permanent mapping. If you have 100 internal users and 100 global addresses, a one- to-one mapping can be done for every user, and every user would have a dedicated global address associated with his inside address. We do not usually have enough global addresses for each user. A typical use of a static mapping is this: We have a server on the inside of our network, or perhaps on a demilitarized zone (DMZ) interface off of our firewall, and we want to allow devices on the Internet access to that specific device. When you create a static mapping for that one server to a global IP address, that global IP address can be used in the Domain Name System (DNS) tables, and users on the Internet can reach our server by name (for example, XXwww.Xserver.XcomX).
