Question 630

A first repair attempt for this situation failed: An engineering group needs visibility into traffic mixes rather than only aggregate port utilization. The review found the mistaken approach of treating a sampled flow report as an exhaustive legal record of every packet. Which targeted recovery action BEST restores the intended design?

Replace or reconfigure the absent standby and validate failover
Adjust queue or capacity policy based on verified microburst measurements
Correct collector connectivity and sample parameters then rerun analysis
Tune the NAE condition and validate a controlled event sequence

Explanation

Correct Answer

Correct collector connectivity and sample parameters then rerun analysis. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when the collector identifies key traffic sources while respecting sampling limitations.

Incorrect Answers

This remediation choice fits a different situation: A 6300 VSF stack has a missing standby member after a replacement. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to correct collector connectivity and sample parameters then rerun analysis.

Question 631

An HPE Aruba Networking engineer faces this wired-network scenario: An application reports congestion but the aggregate uplink bandwidth chart is low. Which implementation action BEST addresses the requirement?

Monitor peer consistency, ISL status and keepalive independently
Use an AOS-CX NAE monitoring agent or suitable telemetry to watch correlated events
Trend authentication events, RADIUS responses and assigned roles across affected ports
Inspect per-class queue drops and microburst evidence instead of relying solely on averages

Explanation

Correct Answer

Averages can hide microbursts and egress queue drops. The targeted implementation is to inspect per-class queue drops and microburst evidence instead of relying solely on averages. The deployment succeeds when congestion events align with queue depth even when five-minute rates look normal.

Incorrect Answers

Explanation

Correct Answer

Stack resiliency depends on known roles and healthy fabric links
Hardware environmental telemetry is relevant to switch reliability
Client authorization health requires protocol and role telemetry
Averages can hide microbursts and egress queue drops

Explanation

Correct Answer

Averages can hide microbursts and egress queue drops. The case therefore calls for this specifically controlled action: inspect per-class queue drops and microburst evidence instead of relying solely on averages. The acceptance evidence is that congestion events align with queue depth even when five-minute rates look normal.

Question 634

A risk review for the following wired-network case asks what should be avoided: An application reports congestion but the aggregate uplink bandwidth chart is low. 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
Clearing counters repeatedly so long-term faults vanish from reports
Treating a sampled flow report as an exhaustive legal record of every packet

Explanation

Correct Answer

Declaring no congestion based only on a low five-minute utilization mean. That shortcut fails because averages can hide microbursts and egress queue drops. Instead, the appropriate approach is to inspect per-class queue drops and microburst evidence instead of relying solely on averages.

Incorrect Answers

Question 635

Before changing switch configuration, an engineer investigates: An application reports congestion but the aggregate uplink bandwidth chart is low. Which FIRST check is most useful for isolating the cause?

Inspect VSX brief state, ISL interface and keepalive reachability
Inspect exporter configuration, sample rates and collector ingestion
Check counter deltas, timestamps and transceiver diagnostics
Check queue statistics, burst windows and class mapping

Explanation

Correct Answer

Check queue statistics, burst windows and class mapping. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that averages can hide microbursts and egress queue drops.

Question 636

An implementation change is planned for: An application reports congestion but the aggregate uplink bandwidth chart is low. Which preventive control BEST reduces unnecessary outage and security risk?

Preserve routing state telemetry across known maintenance windows
Set alert granularity and preserve burst-focused diagnostics
Document sampling bias and scope before using reports for sizing
Set baseline failure rates and monitor policy rollout cohorts

Explanation

Correct Answer

Set alert granularity and preserve burst-focused diagnostics. This safeguard is appropriate before the change to inspect per-class queue drops and microburst evidence instead of relying solely on averages; it reduces exposure to the mistake of declaring no congestion based only on a low five-minute utilization mean.

Incorrect Answers

This prevention choice fits a different situation: An OSPF core reports adjacency oscillation at the same time daily. It does not resolve the stated failure mode. For this case, the decisive prevention choice is to set alert granularity and preserve burst-focused diagnostics.
