CompTIA Network+ (N10-007) — Question 235

Users report that the network is slow. Upon investigation, the technician notices all users are on one large subnet. Which of the following devices should be used to break up broadcast domains?

Answer options

• A. Layer 2 switch
• B. Layer 3 switch
• C. Signal repeater
• D. Bridge
• E. Domain server

Correct answer: B

Explanation

A Layer 3 switch is capable of routing traffic between different VLANs or subnets, effectively breaking up broadcast domains. In contrast, a Layer 2 switch does not perform routing, a signal repeater merely amplifies signals, a bridge connects multiple network segments without breaking up broadcast domains, and a domain server is unrelated to managing network traffic.
