CompTIA Network+ (N10-008) — Question 821

A company streams video to multiple devices across a campus. When this happens, several users report a degradation of network performance. Which of the following would MOST likely address this issue?

Answer options

• A. Enable IGMP snooping on the switches.
• B. Implement another DHCP server.
• C. Reconfigure port tagging for the video traffic.
• D. Change the SSID of the APs.

Correct answer: A

Explanation

Enabling IGMP snooping on the switches helps manage multicast traffic efficiently, reducing network congestion caused by video streaming. The other options do not directly address the multicast traffic issue; adding a DHCP server does not affect multicast, reconfiguring port tagging may not solve the performance problem, and changing the SSID is unrelated to network traffic management.
