Question 640

An HPE Aruba Networking design review examines: A VSX core pair appears online but one peer reports an unhealthy ISL. Which technical principle BEST explains the required approach?

Management connectivity and client-visibility instrumentation are separate
VSX operational state comprises multiple peer communication channels
Link-state telemetry needs alerting and correct ownership to be operationally useful
Client authorization health requires protocol and role telemetry

Explanation

Correct Answer

VSX operational state comprises multiple peer communication channels. The case therefore calls for this specifically controlled action: monitor peer consistency, ISL status and keepalive independently. The acceptance evidence is that the health report distinguishes the affected peer link from the keepalive channel.

Incorrect Answers

Question 641

A risk review for the following wired-network case asks what should be avoided: A VSX core pair appears online but one peer reports an unhealthy ISL. Which assumption creates the GREATEST implementation risk?

Reporting only link state while ignoring port authentication failure events
Declaring no congestion based only on a low five-minute utilization mean
Using a script alert that fires on every minor event with no suppression
Calling both switches healthy simply because both respond to SSH

Explanation

Correct Answer

Calling both switches healthy simply because both respond to SSH. That shortcut fails because vSX operational state comprises multiple peer communication channels. Instead, the appropriate approach is to monitor peer consistency, ISL status and keepalive independently.

Question 642

Before changing switch configuration, an engineer investigates: A VSX core pair appears online but one peer reports an unhealthy ISL. Which FIRST check is most useful for isolating the cause?

Inspect component status, airflow and room temperature history
Inspect VSX brief state, ISL interface and keepalive reachability
Check counter deltas, timestamps and transceiver diagnostics
Inspect Central device context, client-tracking setting and reported endpoints

Explanation

Correct Answer

Inspect VSX brief state, ISL interface and keepalive reachability. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that vSX operational state comprises multiple peer communication channels.

Question 643

An implementation change is planned for: A VSX core pair appears online but one peer reports an unhealthy ISL. Which preventive control BEST reduces unnecessary outage and security risk?

Set thresholds and retain historical baselines
Alert on role loss and rehearse member replacement
Set temperature thresholds and plan cooling maintenance
Alert separately on ISL synchronization and keepalive degradation

Explanation

Correct Answer

Alert separately on ISL synchronization and keepalive degradation. This safeguard is appropriate before the change to monitor peer consistency, ISL status and keepalive independently; it reduces exposure to the mistake of calling both switches healthy simply because both respond to SSH.

Question 644

A first repair attempt for this situation failed: A VSX core pair appears online but one peer reports an unhealthy ISL. The review found the mistaken approach of calling both switches healthy simply because both respond to SSH. Which targeted recovery action BEST restores the intended design?

Adjust queue or capacity policy based on verified microburst measurements
Repair event forwarding and confirm a controlled link-down alert
Repair the indicated peer channel before clearing the VSX incident
Repair the faulty link and confirm error rate remains low

Explanation

Correct Answer

Repair the indicated peer channel before clearing the VSX incident. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when the health report distinguishes the affected peer link from the keepalive channel.

Question 645

An HPE Aruba Networking engineer faces this wired-network scenario: A 6300 VSF stack has a missing standby member after a replacement. Which implementation action BEST addresses the requirement?

Inspect per-class queue drops and microburst evidence instead of relying solely on averages
Monitor fan, temperature and power-supply health with environmental thresholds
Use sampled flow telemetry such as supported sFlow reporting to an approved collector
Review stack member roles, link topology and software version in operational telemetry

Explanation

Correct Answer

Stack resiliency depends on known roles and healthy fabric links. The targeted implementation is to review stack member roles, link topology and software version in operational telemetry. The deployment succeeds when the stack reports an approved conductor and standby with all intended members present.
