Question 620
The HPE AOS-CX switching case is: A file server's disks saturate during backup while all relevant campus uplinks show clean counters and low utilization. Select TWO: a corrective switching action and separate evidence that the correction worked. (Select TWO.)
Explanation
Correct Answers
The targeted correction for A file server's disks saturate during backup while all relevant campus uplinks show clean counters and low utilization is: Correlate the affected endpoint, switch port, upstream path and application service timing before blaming the switching fabric. It reduces the risk that local client faults and server slowness can resemble network degradation, causing disruptive configuration changes that do not help.
A separate operational validation for A file server's disks saturate during backup while all relevant campus uplinks show clean counters and low utilization is: Cross-endpoint and cross-service comparisons isolate whether the measured issue originates on one host or a shared network path. It proves intended behavior instead of accepting configuration presence alone.
Incorrect Answers
This alternative concerns control-plane resource saturation and high cpu; its associated risk is: A storm of protocol events or excessive polling can delay management and routing convergence despite sufficient data-plane bandwidth. The observed case A file server's disks saturate during backup while all relevant campus uplinks show clean counters and low utilization requires the more specific end-node and application-path performance differentiation control. The targeted action is: Correlate the affected endpoint, switch port, upstream path and application service timing before blaming the switching fabric.
This alternative concerns mtu consistency and large-packet forwarding; its associated risk is: A mismatch can create fragmentation or loss and cause application timeouts even while basic ping succeeds. The observed case A file server's disks saturate during backup while all relevant campus uplinks show clean counters and low utilization requires the more specific end-node and application-path performance differentiation control. The targeted action is: Correlate the affected endpoint, switch port, upstream path and application service timing before blaming the switching fabric.
This alternative concerns multicast flooding and igmp querier performance impact; its associated risk is: An absent querier or disabled snooping can flood video to unrelated ports and disrupt nonvideo applications. The observed case A file server's disks saturate during backup while all relevant campus uplinks show clean counters and low utilization requires the more specific end-node and application-path performance differentiation control. The targeted action is: Correlate the affected endpoint, switch port, upstream path and application service timing before blaming the switching fabric.
