CompTIA Cloud+ (CV0-003) — Question 332

A systems administrator is troubleshooting issues with network slowness. Traffic analysis shows that uplink bandwidth on the core switch is often sustained at
125Mbps due to a
combination of production traffic from other sources. Which of the following would BEST resolve the issue?

Answer options

• A. Turn off the servers that use the most bandwidth.
• B. Enable QoS to prioritize production traffic.
• C. Increase the buffer size on the core switch.
• D. Reboot the core switch.

Correct answer: B

Explanation

Enabling QoS allows for prioritization of production traffic, ensuring that critical data is transmitted efficiently even during peak usage, making it the best solution. Turning off servers may disrupt necessary services, increasing buffer size does not directly address traffic prioritization, and rebooting the core switch may provide temporary relief but won't solve the underlying bandwidth issue.
