CompTIA Network+ (N10-009) N10-009 — Question 531

The correct answer is A. Option A: Use RFC1918 addresses internally and the public address block externally on the firewall with NAT.

Explanation

A firewall enforces traffic policy by permitting or blocking connections based on configured rules. Network address translation maps addresses between networks and commonly lets private hosts share public connectivity. This option keeps traffic private / properly secured as required.
