CompTIA Security+ (SY0-701) — Question 400

When trying to access an internal website, an employee reports that a prompt displays, stating that the site is insecure. Which of the following certificate types is the site most likely using?

Answer options

• A. Wildcard
• B. Root of trust
• C. Third-party
• D. Self-signed

Correct answer: D

Explanation

The correct answer is D, as self-signed certificates are often used in internal environments and do not provide the same level of trust as certificates signed by a recognized certificate authority. Options A, B, and C, while valid types of certificates, typically do not lead to security prompts indicating an insecure site.
