Security Fundamentals — Question 76

You create a web server for your school. When users visit your site, they get a certificate error that says your site is not trusted.
What should you do to fix this problem?

Answer options

• A. Install a certificate from a trusted Certificate Authority (CA).
• B. Use a digital signature.
• C. Generate a certificate request.
• D. Enable Public Keys on your website.

Correct answer: A

Explanation

The correct answer is A, as obtaining a certificate from a trusted Certificate Authority (CA) will ensure that users' browsers recognize and trust your site's certificate. Options B, C, and D do not directly address the issue of trust; a digital signature does not replace a trusted certificate, generating a certificate request is part of the process but does not solve the problem, and enabling Public Keys is unrelated to certificate trust validation.
