Computer Networks - IP Addressing

AUse static NAT to map each private IP to a fixed public IP

BEnable NAT overload on the router interface

CConfigure DHCP to assign public IPs to devices

DUse dynamic NAT without port translation

Step-by-Step Solution

Solution:

Step 1: Understand static NAT purpose
Static NAT creates a fixed one-to-one mapping between a private IP and a public IP, allowing specific assignments.
Step 2: Differentiate from other NAT types
NAT overload shares one IP; DHCP does not assign public IPs; dynamic NAT assigns public IPs from a pool but not fixed.
Final Answer:
Use static NAT to map each private IP to a fixed public IP -> Option A
Quick Check:
Static NAT = fixed IP mapping [OK]

Quick Trick: Static NAT fixes private to public IP mapping [OK]

Common Mistakes:

MISTAKES

Confusing static NAT with dynamic NAT
Thinking DHCP assigns public IPs inside NAT
Using NAT overload for fixed IP assignments
