CompTIA A+ Core 1 (220-1101) — Question 261

Which of the following network devices should a technician install in order to isolate voice traffic on the network?

Answer options

• A. Network tap
• B. Managed switch
• C. Hub
• D. DSL filter

Correct answer: B

Explanation

A Managed switch is capable of configuring VLANs to separate voice traffic from data traffic, making it the correct choice. A Network tap is used for monitoring, a Hub broadcasts traffic to all ports which does not isolate traffic, and a DSL filter is used to separate voice and data signals over telephone lines, not within a network.
