CompTIA Network+ (N10-009) — Question 437

A government entity wants to implement technology that can block websites based on country code. Which of the following will best enable this requirement?

Answer options

• A. URL filtering
• B. Content filtering
• C. DNS poisoning
• D. MAC filtering

Correct answer: A

Explanation

URL filtering is the most appropriate method for blocking websites based on their country code, as it allows the specification of rules to permit or deny access to specific URLs. Content filtering focuses on the content of the websites rather than their origin, while DNS poisoning involves corrupting DNS data, which is not a reliable method for blocking websites. MAC filtering restricts access based on device MAC addresses, which is not relevant to website blocking.
