CompTIA Network+ (N10-007) — Question 460

A senior technician is reconfiguring the company's firewall because a number of additional devices have been added to the network. The company has acquired a new VoIP phone system, and a group of junior technicians has set up an experimental lab with access to the Internet. Management has given the team latitude for research and development, but would like the company network to be secure and the performance to remain consistent with existing baselines. Which of the following would be the BEST method to reconfigure the network?

Answer options

• A. The technician should put the junior team's lab in a VLAN and the phone system in the DMZ.
• B. The technician should put the junior team's lab in a DMZ and the phone system in a VLAN.
• C. The technician should put the junior team's lab in the LAN and the phone system in the WAN.
• D. The technician should put the junior team's lab in the WAN and the phone system in a WLAN

Correct answer: B

Explanation

Option B is correct because placing the junior team's lab in a DMZ allows them to access the Internet while isolating them from the main network, enhancing security. Meanwhile, placing the VoIP phone system in a VLAN ensures it has a secure network segment, optimizing performance and protecting it from potential threats from the experimental lab. The other options do not adequately separate the experimental lab from the main network, which could compromise security and performance.
