CompTIA A+ Core 1 (220-1101) — Question 205

A SOHO customer would like to purchase network hardware to enhance security. The hardware should perform stateful packet inspection. Which of the following would BEST address the customer's need?

Answer options

• A. Switch
• B. Firewall
• C. Router
• D. Proxy

Correct answer: B

Explanation

The correct answer is B, Firewall, as it is specifically designed to perform stateful packet inspection, enhancing security by monitoring active connections. A Switch (A) primarily manages data traffic within a local network and does not provide security features. A Router (C) directs traffic between networks but lacks the depth of security inspection. A Proxy (D) serves as an intermediary for requests but does not perform stateful packet inspection.
