Question 690
The HPE AOS-CX switching case is: An interface reports up but has a rapidly growing receive error count after a fiber patch replacement. Which TWO choices together provide the targeted remedy and independent validation? (Select TWO.)
Explanation
Correct Answers
The targeted correction for An interface reports up but has a rapidly growing receive error count after a fiber patch replacement is: Interpret interface administrative and operational state, negotiated speed, error counters and trend direction in context before taking action. It reduces the risk that a single green link status can conceal elevated errors, mismatched speed or an emerging optical failure.
A separate operational validation for An interface reports up but has a rapidly growing receive error count after a fiber patch replacement is: A measured trend and cross-check distinguish an actionable fault from normal transient changes and verify remediation. It proves intended behavior instead of accepting configuration presence alone.
Incorrect Answers
This alternative concerns syslog severity timestamps and event context; its associated risk is: Incorrect device time or unfiltered log noise can hide the precise moment of a route failure or security incident. The observed case An interface reports up but has a rapidly growing receive error count after a fiber patch replacement requires the more specific switch interface telemetry and threshold interpretation control. The targeted action is: Interpret interface administrative and operational state, negotiated speed, error counters and trend direction in context before taking action.
This alternative concerns multicast group and receiver telemetry interpretation; its associated risk is: Excess replication can degrade other applications while loss of membership state can silently stop authorized streams. The observed case An interface reports up but has a rapidly growing receive error count after a fiber patch replacement requires the more specific switch interface telemetry and threshold interpretation control. The targeted action is: Interpret interface administrative and operational state, negotiated speed, error counters and trend direction in context before taking action.
This alternative concerns vsf member and stack topology observability; its associated risk is: A surviving logical stack address can conceal a missing member and hundreds of failed physical user ports. The observed case An interface reports up but has a rapidly growing receive error count after a fiber patch replacement requires the more specific switch interface telemetry and threshold interpretation control. The targeted action is: Interpret interface administrative and operational state, negotiated speed, error counters and trend direction in context before taking action.
