CompTIA CySA+ (CS0-001) — Question 118

A security analyst received several service tickets reporting that a company storefront website is not accessible by internal domain users. However, external users are accessing the website without issue. Which of the following is the MOST likely reason for this behavior?

Answer options

• A. The FQDN is incorrect.
• B. The DNS server is corrupted.
• C. The time synchronization server is corrupted.
• D. The certificate is expired.

Correct answer: B

Explanation

The most likely reason for internal users being unable to access the website while external users can is a corrupted DNS server, which may prevent internal domain name resolution. If the DNS server is malfunctioning, internal users would not be able to resolve the website's address correctly. The other options, such as the FQDN being incorrect, time synchronization issues, or an expired certificate, would not typically result in the described accessibility issue for internal users.
