Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
PAT (overload)
Why this is correct
Correct. PAT uses port numbers to multiplex multiple internal hosts to a single public IP.
- ✗
Identity NAT
Why it's wrong here
Identity NAT bypasses translation, does not share IPs.
- ✗
Static NAT
Why it's wrong here
Static NAT provides one-to-one mapping, not sharing.
- ✗
Dynamic NAT
Why it's wrong here
Dynamic NAT uses a pool of public IPs, but does not overload ports.
