CompTIA A+ Core 1 (220-1101) — Question 181

A home user has purchased a subscription for a service that blocks malicious sites by preventing them from resolving correctly. Which of the following settings MOST likely needs to be changed on the user's router to enable this functionality?

Answer options

Correct answer: A

Explanation

The correct answer is A, as changing the DNS server settings on the router allows the user to direct their web traffic through the service that blocks malicious sites. The other options, such as Port forwarding, Perimeter network, Universal PnP, and DHCP server, do not directly affect how DNS queries are resolved and thus are not relevant to enabling the blocking of malicious sites.
