CompTIA Security+ (SY0-501) — Question 778

A network technician needs to monitor and view the websites that are visited by an employee. The employee is connected to a network switch. Which of the following would allow the technician to monitor the employee's web traffic?

Answer options

• A. Implement promiscuous mode on the NIC of the employee's computer.
• B. Install and configured a transparent proxy server.
• C. Run a vulnerability scanner to capture DNS packets on the router.
• D. Configure a VPN to forward packets to the technician's computer.

Correct answer: B

Explanation

The correct answer is B, as a transparent proxy server can intercept and log web traffic without requiring any configuration on the client's device. Option A is incorrect because promiscuous mode would only allow monitoring on the local network, not through a switch. Option C does not provide a method to monitor web traffic specifically, as it focuses on DNS packets. Option D suggests using a VPN, which would not inherently allow monitoring of web traffic in this context.
