CompTIA Cloud+ (CV0-003) — Question 125

A company recently adjusted its load-balancer encryption policies to support only TLSv1.3. Soon after the change was made, several customers began reporting they could not access their website. Which of the following is the MOST likely cause of the issue?

Answer options

• A. The certificate is expired.
• B. There is a mismatch between the key and the certificate.
• C. The customers are using an unsupported OS.
• D. The load balancer was misconfigured.

Correct answer: C

Explanation

The most likely cause of the issue is that customers are using an unsupported OS that does not support TLSv1.3. Options A and B are less plausible since they relate to certificate issues rather than protocol support, and option D suggests a configuration issue which is not indicated by the customers' reports.
