CompTIA A+ Core 1 (220-1001) — Question 388

Which of the following devices is used to implement network security policies for an environment?

Answer options

• A. Firewall
• B. Managed switch
• C. Repeater
• D. Gateway

Correct answer: A

Explanation

The correct answer is A, Firewall, as it is specifically designed to control and enforce network security policies by monitoring and regulating incoming and outgoing network traffic. The other options do not serve this primary purpose; a Managed switch primarily handles data traffic management, a Repeater amplifies signals to extend range, and a Gateway acts as a point of entry to connect different networks.
