CompTIA Network+ (N10-007) — Question 45

An employee reports an error when visiting a website using SSL, and a message is displayed warning of an invalid certificate. Which of the following could be occurring?

Answer options

• A. Phishing
• B. DDoS
• C. Evil twin
• D. MITM
• E. OCSP stapling

Correct answer: C

Explanation

The correct answer is C, Evil twin, which refers to a rogue access point that mimics a legitimate one, potentially leading to SSL certificate warnings. A, Phishing, is related to deceptive attempts to obtain sensitive information, but does not pertain to SSL errors directly. B, DDoS, involves overwhelming a server with traffic, not certificate issues. D, MITM, is a man-in-the-middle attack that can cause such warnings but is not the most appropriate answer in this context. E, OCSP stapling, is a method to check the validity of certificates and not a cause for an invalid certificate warning.
