Selected Answer: B

The issue here is buffer overflows and packet drops, which are causing audio lag during phone conferences. Since the budget does not allow for new hardware, the best solution is to prioritize VoIP traffic using Quality of Service (QoS) rules. QoS helps by: ✔ Prioritizing VoIP packets over less time-sensitive data (e.g., web browsing, file downloads). ✔ Reducing jitter and latency, ensuring smooth real-time communication. ✔ Preventing packet loss by ensuring voice traffic gets priority through network bottlenecks.
