CompTIA Network+ (N10-007) — Question 154

Which of the following devices should a network administrator configure on the outermost part of the network?

Answer options

• A. Media converter
• B. Switch
• C. Modem
• D. Firewall

Correct answer: D

Explanation

The correct answer is D, as a firewall is essential for protecting the network from external threats and controlling incoming and outgoing traffic. The other devices like media converters, switches, and modems serve different purposes within the network but do not primarily provide the security functions that a firewall does.
