CompTIA CASP+ (CAS-004) — Question 595

A user experiences an HTTPS connection error when trying to access an Internet banking website from a corporate laptop. The user then opens a browser on a mobile phone and is able to access the same Internet banking website without issue. Which of the following security configurations is MOST likely the cause of the error?

Answer options

• A. HSTS
• B. TLS 1.2
• C. Certificate pinning
• D. Client authentication

Correct answer: C

Explanation

The correct answer is C, Certificate pinning, because it restricts which certificates the browser will accept for a specific site, potentially causing access issues if the corporate laptop does not recognize the pinned certificate. The other options, like HSTS, TLS 1.2, and Client authentication, are less likely to cause a connection error in this scenario.
