CompTIA Network+ (N10-007) — Question 206

A network engineer is designing a new network for a remote site. The remote site consists of ten desktop computers, ten VoIP phones, and two network printers.
In addition, two of the desktop computers at the remote site will be used by managers who should be on a separate network from the other eight computers.
Which of the following represents the BEST configuration for the remote site?

Answer options

• A. One router connected to one 24-port switch configured with three VLANS: one for the manager's computers and printer, one for the other computers and printer, and one for the VoIP phones
• B. Two routers with each router connected to a 12-port switch, with a firewall connected to the switch connected to the manager's desktop computers, VoIP phones, and printer
• C. One router connected to one 12-port switch configured for the manager's computers, phones, and printer, and one 12-port switch configured for the other computers, VoIP phones, and printer
• D. One router connected to one 24-port switch configured with two VLANS: one for the manager's computers, VoIP phones, and printer, and one for the other computers, VoIP phones, and printer

Correct answer: A

Explanation

Option A is the best choice because it effectively uses three VLANs to separate the managers' computers, the other computers, and the VoIP phones, ensuring proper segmentation. Option B is less efficient as it requires two routers, which complicates the setup. Option C does not provide sufficient VLAN separation for the managers and other users. Option D only has two VLANs, which does not meet the requirement for separation of the managers from the other PCs.
