CompTIA Network+ (N10-007) — Question 487
A company has hundreds of nodes on a single subnet and has decided to implement VLANs. Which of the following BEST describes the benefit of this approach?
Answer options
- A. It segments broadcast domains in the network infrastructure
- B. It provides a faster port to all servers
- C. It provides multiple collision domains on one switchport
- D. It provides multiple broadcast domains within a single collision domain
Correct answer: A
Explanation
The correct answer is A, as VLANs effectively segment broadcast domains, reducing unnecessary traffic and improving network efficiency. Option B is incorrect because VLANs do not inherently provide faster ports. Option C is misleading since VLANs create logical segmentation rather than physical collision domains on a switch port. Option D is also incorrect because VLANs create separate broadcast domains, not multiple within a single collision domain.
