QUESTION 1
Network Address Translator (NAT) parses the IP packet header and automatically replaces the source or destination address in the packet header so that users can access the public network using private IP addresses.

A. NAPT
B. No-PAT
C. Destination NAT
D. NAT Server
Correct Answer: ABCD
QUESTION 2
On a data communication network, the network layer header of a packet sent by the source node carries the network layer addresses of both the source and destination nodes of the packet.

After one is found, the packet is forwarded accordingly.
A. Source IP
B. Destination MAC
C. Source MAC
D. Destination IP
Correct Answer: D
