Which of the following statements regarding the queuing scheme of IP Real Time Transport Protocol (RTP) prioritization is valid?
A.
It is capable ofsupporting TCP traffic.
B.
It is used mainly for interactive traffic.
C.
It is responsible for providing low latency queuing by providing a high priority queue.
D.
Packets that exceed the queue’s configured rate are placed into the default queue.
Explanation:
IP RTP Prioritization is an add-on to WFQ to support low-delay propagation of packets.
It can be used for UDP traffic only.
IP RTP Prioritization also polices the high priority traffic to prevent starvation of other queues.
IP RTP Prioritization supports one high priority queue. Packets from this queue are scheduled ahead of other packets as long as they are within the configured rate.
Excess packets are dropped.
