Cisco CCNA mock exam questions sample test – Question 65

.Which of the following NAT terms refers to a registered address that represents an inside host to an outside network?

A. inside global
B. outside global
C. inside local
D. outside local

Correct Answer: A

Explanation:
An inside global address is the registered or public address assigned by the NAT server to an inside host. To the outside world it is only address seen for the host. The real (private)
address, called the inside local, remains hidden.
The outside global address is the public address of a host that is outside the network connecting to the network. It the NAT server is also translating incoming addresses as well as
outgoing addresses the address it assigns to the external host is called the outside local address.
The inside local address is the private IP address assigned to a host inside the network. The outside local is the address of a host outside the network as seen by hosts inside the
network.
For example, in the diagram below, PC1 is sending a packet to the Web server. R1 is operating in NAT overload mode, which means that it maps all internal private IP addresses to a
single public IP address.
Below is a listing of the names assigned to certain addresses in the diagram:
Inside local 192.168.5.6
Inside global 58.59.6.3
Outside local 192.168.5.1
Outside global 25.67.5.7
