CompTIA Network+ (N10-006) — Question 42

A technician needs to limit the amount of broadcast traffic on a network and allow different segments to communicate with each other.
Which of the following options would satisfy these requirements?

Answer options

• A. Add a router and enable OSPF.
• B. Add a layer 3 switch and create a VLAN.
• C. Add a bridge between two switches.
• D. Add a firewall and implement proper ACL.

Correct answer: B

Explanation

The correct answer is B because a layer 3 switch can create VLANs, which effectively segment the network and reduce broadcast traffic while still allowing inter-VLAN communication. Option A is incorrect as adding a router and enabling OSPF does not directly limit broadcast traffic on the same network segment. Option C is also incorrect because a bridge does not provide the level of segmentation needed to control broadcast traffic effectively. Option D, while it involves controlling traffic, does not specifically address the need to limit broadcast traffic across different segments.
