CompTIA Network+ (N10-009) — Question 362

Which of the following should a company implement in order to share a single IP address among all the employees in the office?

Answer options

• A. STP
• B. BGP
• C. PAT
• D. VXLAN

Correct answer: C

Explanation

The correct answer is PAT (Port Address Translation), which allows multiple devices on a local network to share a single public IP address by differentiating their connections through port numbers. STP (Spanning Tree Protocol) is unrelated to IP address sharing, BGP (Border Gateway Protocol) is used for routing between autonomous systems, and VXLAN (Virtual Extensible LAN) is a network virtualization technology, not specifically for IP sharing.
