CompTIA Security+ (SY0-701) — Question 591

An administrator implements web-filtering products but still sees that users are visiting malicious links. Which of the following configuration items does the security administrator need to review?

Answer options

• A. Intrusion prevention system
• B. Content categorization
• C. Encryption
• D. DNS service

Correct answer: B

Explanation

The correct answer is B, as content categorization directly influences the effectiveness of web-filtering by determining how websites are classified and blocked. If the categorization is inaccurate or not comprehensive, users may still access malicious sites. The other options, such as the Intrusion Prevention System, Encryption, and DNS service, do not specifically address the issue of web-filtering efficacy.
