CompTIA Network+ (N10-009) — Question 164

Which of the following allows an organization to map multiple internal devices to a single external-facing IP address?

Answer options

• A. NAT
• B. BGP
• C. OSPF
• D. FHRP

Correct answer: A

Explanation

NAT (Network Address Translation) is designed to allow multiple internal devices to share a single external IP address, making it essential for conserving IP addresses. BGP (Border Gateway Protocol), OSPF (Open Shortest Path First), and FHRP (First Hop Redundancy Protocol) serve different networking purposes and do not perform this specific function.
