CompTIA Network+ (N10-007) — Question 688

An administrator recently implemented new SOHO routers for a company's teleworking employees. Before deploying the routers, the administrator changed the default credentials and disabled unnecessary services. Within a few days of deployment, hackers gained access to the routers. Which of the following is the
MOST important thing the administrator forgot to do?

Answer options

• A. Disable unused physical router ports.
• B. Generate new encryption keys.
• C. Upgrade the router firmware.
• D. Create a database of file hashes on the router.

Correct answer: A

Explanation

The correct answer is A, as disabling unused physical router ports helps to prevent unauthorized access through those ports. Generating new encryption keys (B) and upgrading the router firmware (C) are important security measures, but they do not address physical access vulnerabilities as directly as disabling ports. Creating a database of file hashes (D) is not a primary security measure for preventing unauthorized access to the router itself.
