Throughout the day, a sales team experiences videoconference performance issues when the accounting department runs reports. Which of the following is the best solution?

Question

Options

• ARunning the accounting department's reports outside of business hours
• BUsing a load balancer to split the video traffic evenly
• CConfiguring QoS on the corporate network switches
• DIncreasing the throughput on the network by purchasing high-end switches

• A
  9% (3)
• B
  3% (1)
• C
  81% (26)
• D
  6% (2)

Explanation

Quality of Service (QoS) allows the network to prioritize time-sensitive, latency-sensitive traffic - like video conferencing - over bulk, best-effort traffic like database reports. By assigning higher priority queues to video traffic (e.g., via DSCP marking), QoS ensures the sales team's videoconferences receive adequate bandwidth and low latency even when accounting's report queries consume significant bandwidth. Running reports after hours (A) is an operational workaround, not a technical solution. A load balancer (B) distributes traffic across servers, not across time-sensitive vs. bulk flows. Upgrading switches (D) adds capacity but does not solve the prioritization problem - higher throughput switches won't inherently prefer video over bulk traffic.
