Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Identity NAT
Why it's wrong here
Identity NAT bypasses translation; not suitable for providing a public IP.
- ✗
Dynamic NAT
Why it's wrong here
Dynamic NAT assigns from a pool and is not fixed.
- ✗
Dynamic PAT (overload)
Why it's wrong here
PAT uses port translation and does not guarantee a fixed public IP.
- ✓
Static NAT
Why this is correct
Correct; static NAT creates a permanent one-to-one mapping.
