CompTIA Network+ (N10-007) — Question 316

A systems administrator has recently purchased and installed a large electronic signage screen for the company's parking garage. The screen's management software was installed on a server with a public IP address to allow remote management. The systems administrator is now troubleshooting an issue with the screen displaying unknown, random, and inappropriate messages. Which of the following is MOST effective in resolving this issue?

Answer options

• A. Changing the management software's default credentials
• B. Disabling unnecessary services from the server and management software
• C. Changing the management software's default port
• D. Replacing the management software's self-signed certificate with a valid certificate

Correct answer: A

Explanation

The correct answer is A, as changing the management software's default credentials helps prevent unauthorized access that could lead to inappropriate messages being displayed. The other options, while they may enhance security or improve performance, do not directly address the root cause of the inappropriate content being shown on the screen.
