Question 360
The HPE AOS-CX switching case is: A video conference appears healthy when links are empty but voice jitter spikes when large transfers start. Select TWO: a corrective switching action and separate evidence that the correction worked. (Select TWO.)
Explanation
Correct Answers
The targeted correction for A video conference appears healthy when links are empty but voice jitter spikes when large transfers start is: Apply supported classification and DSCP or CoS trust policies at appropriate access boundaries instead of trusting every endpoint marking. It reduces the risk that untrusted hosts can mark bulk flows as high priority and starve real-time applications during congestion.
A separate operational validation for A video conference appears healthy when links are empty but voice jitter spikes when large transfers start is: Traffic capture and queue statistics demonstrate intended priority treatment for voice while untrusted markings are normalized. It proves intended behavior instead of accepting configuration presence alone.
Incorrect Answers
This alternative concerns egress scheduling queue mapping and congestion control; its associated risk is: Incorrect queue assignment and strict-priority overuse can cause starvation, loss and unstable latency under load. The observed case A video conference appears healthy when links are empty but voice jitter spikes when large transfers start requires the more specific dscp and cos classification trust boundaries control. The targeted action is: Apply supported classification and DSCP or CoS trust policies at appropriate access boundaries instead of trusting every endpoint marking.
This alternative concerns interface and route operational show-command discipline; its associated risk is: An administratively up interface does not establish that tagging, adjacency or end-to-end forwarding works correctly. The observed case A video conference appears healthy when links are empty but voice jitter spikes when large transfers start requires the more specific dscp and cos classification trust boundaries control. The targeted action is: Apply supported classification and DSCP or CoS trust policies at appropriate access boundaries instead of trusting every endpoint marking.
This alternative concerns qos policing shaping and trust verification; its associated risk is: A policer applied in the wrong direction can drop desired traffic, while shaping on the wrong interface does not alleviate the bottleneck. The observed case A video conference appears healthy when links are empty but voice jitter spikes when large transfers start requires the more specific dscp and cos classification trust boundaries control. The targeted action is: Apply supported classification and DSCP or CoS trust policies at appropriate access boundaries instead of trusting every endpoint marking.
