CompTIA Cloud+ (CV0-003) — Question 291

A systems administrator is troubleshooting issues with audio lag during phone conferences. When looking at the core switch, the administrator notices its buffers are consistently full, and packets are being dropped due to the large number being sent and received. There is no room in the budget for new hardware, but it is critical that the audio lag be fixed immediately. Which of the following will most likely resolve the issue?

Answer options

• A. Enable compression of audio traffic.
• B. Configure QoS rules for VoIP traffic.
• C. Verify that the gateway uplink is not saturated
• D. Add an exception to IPS for voice traffic.

Correct answer: B

Explanation

The correct answer is B, as configuring QoS rules for VoIP traffic prioritizes audio packets over other types of traffic, reducing lag. Option A may help in reducing bandwidth usage but does not address packet prioritization. Option C is important but does not directly solve the issue of audio lag. Option D does not provide a solution to the underlying congestion problem.
