Q: Which method applies when a router and a client both utilize the same source port for Network Address Translation (NAT)?
- Preservation
- Forwarding
- Masquerading
- Translation
Explanation: PAT, which stands for “Port Address Translation,” is the term used to describe the method that is used in Network Address Translation (NAT), in which a source port that is selected by a client is the same port that is utilized by a router. A sort of network address translation (NAT) known as PAT transfers numerous private IP addresses to a single public IP address. However, to differentiate between the connections, it makes use of distinct source ports. Additionally, it is referred to as “NAT overload” since it causes the use of a single public IP address to be overloaded with many private IP addresses and source port combinations.
