CompTIA Network+ (N10-009) — Question 181

A security analyst wants to control internet access based on site reputation and categorization. The analyst needs a solution that does not require traffic flow changes. Which of the following solutions would most likely meet these requirements?

Answer options

• A. Proxy
• B. DNS filtering
• C. Router ACL
• D. Load balancer

Correct answer: B

Explanation

DNS filtering is an effective method for controlling internet access based on site reputation and categorization without needing to alter how traffic flows. In contrast, a Proxy requires routing traffic through it, Router ACLs apply rules at the network layer which may require traffic modifications, and Load balancers are primarily focused on distributing traffic rather than filtering access.
