The two QoS guidelines that are recommended for provisioning interactive video traffic are:
D. Interactive video should be marked to DSCP CS4. E. Jitter should be no more than 30 ms.
Explanation:
DSCP (Differentiated Services Code Point) is a protocol used to prioritize traffic on a network. It is important to mark interactive video traffic with a DSCP value that reflects its importance so that it can be given higher priority in the network. CS4 is a commonly used DSCP value for interactive video traffic, and it should be used to mark this traffic.
Jitter is the variation in the delay between packets arriving at the destination. It is important to keep jitter low for interactive video traffic to ensure that the video is delivered smoothly and without interruptions. A jitter value of no more than 30 ms is recommended for interactive video traffic.
The other answer options are not correct or not relevant to the question.
A. Latency should be no more than 4-5 seconds: This answer option is incorrect because latency is the delay in the transmission of data and it is not specific to interactive video traffic.
B. Overprovision interactive video queues by 20% to accommodate bursts: This answer option is not recommended because overprovisioning queues can lead to network congestion and negatively impact other traffic.
C. Loss should be no more than 5%: This answer option is not specific to interactive video traffic and is not a recommended guideline for provisioning this type of traffic.
