Question 590

The HPE AOS-CX switching case is: A distribution link temporarily blocks due to a mismatched MST instance mapping and applications lose connectivity. Which TWO choices together provide the targeted remedy and independent validation? (Select TWO.)

  1. Correlate MSTP port roles, root changes and topology-change counters with periods of interrupted forwarding.
  2. A fault simulation demonstrates expected alternative path convergence with stable root priority and no recurring topology flaps.
  3. Monitor multicast membership and flooding counters to distinguish oversized replication from legitimate receiver traffic.
  4. Packet captures and class drop counters show expected markings and acceptable loss and latency with congestion reproduced.
  5. Correlate the affected endpoint, switch port, upstream path and application service timing before blaming the switching fabric.

Explanation

Correct Answers

A:

The targeted correction for A distribution link temporarily blocks due to a mismatched MST instance mapping and applications lose connectivity is: Correlate MSTP port roles, root changes and topology-change counters with periods of interrupted forwarding. It reduces the risk that repeated topology changes can interrupt latency-sensitive services even if average switch CPU and link utilization are normal.

B:

A separate operational validation for A distribution link temporarily blocks due to a mismatched MST instance mapping and applications lose connectivity is: A fault simulation demonstrates expected alternative path convergence with stable root priority and no recurring topology flaps. It proves intended behavior instead of accepting configuration presence alone.

Incorrect Answers

C:

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 distribution link temporarily blocks due to a mismatched MST instance mapping and applications lose connectivity requires the more specific spanning-tree convergence and topology-change churn control. The targeted action is: Correlate MSTP port roles, root changes and topology-change counters with periods of interrupted forwarding.

D:

This alternative concerns qos misclassification and queue starvation; its associated risk is: An incorrect high-priority class can starve the intended protected service during busy periods. The observed case A distribution link temporarily blocks due to a mismatched MST instance mapping and applications lose connectivity requires the more specific spanning-tree convergence and topology-change churn control. The targeted action is: Correlate MSTP port roles, root changes and topology-change counters with periods of interrupted forwarding.

E:

This alternative concerns end-node and application-path performance differentiation; its associated risk is: Local client faults and server slowness can resemble network degradation, causing disruptive configuration changes that do not help. The observed case A distribution link temporarily blocks due to a mismatched MST instance mapping and applications lose connectivity requires the more specific spanning-tree convergence and topology-change churn control. The targeted action is: Correlate MSTP port roles, root changes and topology-change counters with periods of interrupted forwarding.

Question 591

An HPE Aruba Networking engineer observes: A help desk blames multicast membership timers while STP port-state transitions coincide precisely with the interruptions. The corrective solution must keep intended connectivity, segmentation, and operational resilience. Which response best satisfies the technical requirement without disrupting unrelated traffic?

  1. Correlate MSTP port roles, root changes and topology-change counters with periods of interrupted forwarding.
  2. Separate physical CRC errors, output discards and sustained utilization to identify whether throughput is limited by cabling or queue congestion.
  3. Use supported CPU, process, routing and management telemetry to differentiate control-plane overload from simple forwarding congestion.
  4. Verify the supported MTU across ingress, routed uplinks and any overlay encapsulation path when small packets work but larger payloads fail.

Explanation

Correct Answer

A:

The targeted action is: Correlate MSTP port roles, root changes and topology-change counters with periods of interrupted forwarding.

C:

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 help desk blames multicast membership timers while STP port-state transitions coincide precisely with the interruptions requires the more specific spanning-tree convergence and topology-change churn control. The targeted action is: Correlate MSTP port roles, root changes and topology-change counters with periods of interrupted forwarding.

D:

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 help desk blames multicast membership timers while STP port-state transitions coincide precisely with the interruptions requires the more specific spanning-tree convergence and topology-change churn control. The targeted action is: Correlate MSTP port roles, root changes and topology-change counters with periods of interrupted forwarding.

Question 592

The switch operations team reports: A help desk blames multicast membership timers while STP port-state transitions coincide precisely with the interruptions. What is the most relevant operational exposure in this switching scenario?
