CompTIA Network+ (N10-006) — Question 47

Which of the following is an advantage of utilizing a Layer 2 switch rather than a hub?

Answer options

• A. A switch avoids broadcast storms
• B. A switch detects frame collisions
• C. A switch increases broadcast domains
• D. A switch increases collision domains

Correct answer: B

Explanation

The correct answer is B because a Layer 2 switch can identify and manage frame collisions within its own collision domain, enhancing network efficiency. Options A, C, and D are incorrect; while a switch can help reduce broadcast storms, it does not increase broadcast domains and actually reduces collision domains compared to a hub.
