CompTIA Network+ (N10-009) — Question 148

A network engineer receives a vendor alert regarding a vulnerability in a router CPU. Which of the following should the engineer do to resolve the issue?

Answer options

• A. Update the firmware.
• B. Replace the system board.
• C. Patch the OS.
• D. Isolate the system.

Correct answer: A

Explanation

Updating the firmware is the correct response as it often includes fixes for known vulnerabilities, specifically for hardware components like the CPU. Replacing the system board (B) is unnecessary and more costly, while patching the OS (C) may not directly address CPU vulnerabilities. Isolating the system (D) is a temporary measure and does not resolve the underlying issue.
