CompTIA Network+ (N10-007) — Question 248

Which of the following is the number of broadcast domain that are created when using an unmanaged 12-port switch?

Answer options

• A. 0
• B. 1
• C. 2
• D. 6
• E. 12

Correct answer: B

Explanation

An unmanaged switch operates at Layer 2 and does not segment the network into multiple broadcast domains, thus creating only one broadcast domain for all ports. The other options incorrectly suggest multiple broadcast domains, which would require routers or managed switches for segmentation.
