CompTIA Security+ (SY0-501) — Question 937

A company is deploying a new VoIP phone system. They require 99.999% uptime for their phone service and are concerned about their existing data network interfering with the VoIP phone system. The core switches in the existing data network are almost fully saturated.
Which of the following options will pro-vide the best performance and availability for both the VoIP traffic, as well as the traffic on the existing data network?

Answer options

• A. Put the VoIP network into a different VLAN than the existing data network.
• B. Upgrade the edge switches from 10/100/1000 to improve network speed
• C. Physically separate the VoIP phones from the data network
• D. Implement flood guards on the data network

Correct answer: A

Explanation

The correct answer is A, as placing the VoIP network in a separate VLAN will help to segment the traffic, reducing interference and ensuring better performance and availability for VoIP. Option B, while it might improve speed, does not address the saturation issue directly. Option C could be impractical and expensive, and option D would not effectively resolve the underlying saturation problem.
