Which of the following would BEST resolve the issue?

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?
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.

Answer: B

Explanation:

The best solution to resolve the issue of network slowness caused by high uplink bandwidth utilization on the core switch is to enable quality of service (QoS) to prioritize production traffic over other types of traffic. QoS is a mechanism that allows network administrators to classify and manage network traffic according to its importance, latency, bandwidth, and reliability requirements. By enabling QoS, the core switch can allocate more resources and guarantee better performance for production traffic, while limiting or dropping less critical traffic.
