CompTIA Network+ (N10-007) — Question 191

A switch has detected duplicate broadcast messages sourced from a second port. The broadcasts continue to be transmitted and duplicated until the amount of traffic causes severe performance issues. Which of the following should be configured to prevent this behavior?

Answer options

• A. BPDU guard
• B. DHCP snooping
• C. ARP protection
• D. Spanning tree

Correct answer: D

Explanation

The correct answer is D, Spanning tree, as it helps prevent loops in the network that can cause broadcast storms. The other options, such as BPDU guard, DHCP snooping, and ARP protection, serve specific security functions but do not address the broadcast duplication issue directly.
