What type of queuing provides the best quality for voice applications?
- custom queuing
- FIFO queuing
- priority queuing
- weighted round robin (WRR) queuing
Explanation: Voice applications are very sensitive to bandwidth delays, latency, and jitter and would be most suited to the priority queuing method. Priority queuing (PQ) is a set of four queues (high,medium,normal and low). Because all the queues are served in strict priority order, this makes it suitable for voice applications that need high priority.
