CompTIA Network+ (N10-006) — Question 46

A technician is configuring a computer lab at a school. The computers need to be able to communicate with each other, but students using the computers should not be able to access the internet.
Which of the following rules on the firewall should the technician configure for the lab computers?

Answer options

Correct answer: C

Explanation

The correct answer is C, as blocking WAN to LAN traffic prevents any outside internet access to the lab computers while allowing them to communicate internally. Option A would prevent communication between the computers, and option B would not allow them to access the internet, but it doesn't address the incoming traffic from the internet. Option D is irrelevant as it pertains to wireless LANs, which are not mentioned in the scenario.
