HP HPE7-A08 Practice Test 50

Question 490

A first repair attempt for this situation failed: Video traffic suffers delay only when backups saturate an interbuilding uplink. The review found the mistaken approach of assuming a reachable gateway proves every class has adequate bandwidth. Which targeted recovery action BEST restores the intended design?

Reduce PoE load or upgrade supported supply capacity and retest
Tune the offending script or control-plane process then monitor stability
Adjust class mapping or shaping after measuring the congested queue
Disconnect the unintended loop then restore tested spanning-tree controls

Explanation

Correct Answer

Adjust class mapping or shaping after measuring the congested queue. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when queue drops correlate with backups and improve after controlled QoS adjustment.

Incorrect Answers

This remediation choice fits a different situation: Some PoE cameras reboot during heavy utilization although data ports stay up. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to adjust class mapping or shaping after measuring the congested queue.

This remediation choice fits a different situation: Switch CPU usage spikes periodically while network links remain otherwise stable. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to adjust class mapping or shaping after measuring the congested queue.

Question 491

An HPE Aruba Networking engineer faces this wired-network scenario: A network interface experiences high frame errors at peak load but no routing alarms. Which implementation action BEST addresses the requirement?

Investigate spanning-tree reconvergence and redundancy path selection
Investigate total PoE budget and allocation events at the switch
Diagnose queue congestion and class scheduling before adding more routing changes
Diagnose physical layer errors using CRC counters, optic levels and patch tests

Explanation

Correct Answer

Frame integrity errors often reveal physical problems rather than route policy. The targeted implementation is to diagnose physical layer errors using CRC counters, optic levels and patch tests. The deployment succeeds when replacing faulty media reduces CRC errors under repeatable traffic load.

Incorrect Answers

This implementation choice fits a different situation: Voice calls drop briefly whenever a distribution link flaps. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to diagnose physical layer errors using CRC counters, optic levels and patch tests.

Question 492

After implementing the approved change — Diagnose physical layer errors using CRC counters, optic levels and patch tests — for this scenario: A network interface experiences high frame errors at peak load but no routing alarms. Which observed result BEST verifies the outcome?

The link transition no longer causes long user outages under test
Replacing faulty media reduces CRC errors under repeatable traffic load
Broadcast rate drops after the redundant uncontrolled path is removed
Camera power remains stable after proper budgeting under full load

Explanation

Correct Answer

Replacing faulty media reduces CRC errors under repeatable traffic load. This is the observable acceptance evidence for the decision to diagnose physical layer errors using CRC counters, optic levels and patch tests. It demonstrates the principle that frame integrity errors often reveal physical problems rather than route policy.

Question 493

An HPE Aruba Networking design review examines: A network interface experiences high frame errors at peak load but no routing alarms. Which technical principle BEST explains the required approach?

ECMP load sharing is flow-based and may not evenly split every single flow
QoS congestion can degrade selected traffic even while physical links stay up
MTU mismatch can break selected flows while basic pings still work
Frame integrity errors often reveal physical problems rather than route policy

Explanation

Correct Answer

Frame integrity errors often reveal physical problems rather than route policy. The case therefore calls for this specifically controlled action: diagnose physical layer errors using CRC counters, optic levels and patch tests. The acceptance evidence is that replacing faulty media reduces CRC errors under repeatable traffic load.

Incorrect Answers

Question 494

A risk review for the following wired-network case asks what should be avoided: A network interface experiences high frame errors at peak load but no routing alarms. Which assumption creates the GREATEST implementation risk?

Turning off all multicast routing to stop one flooded VLAN
Increasing QoS priority to hide a damaged fiber link
Claiming a single large flow must always divide evenly across all paths
Assuming small successful pings prove every packet size will pass

Explanation

Correct Answer

Increasing QoS priority to hide a damaged fiber link. That shortcut fails because frame integrity errors often reveal physical problems rather than route policy. Instead, the appropriate approach is to diagnose physical layer errors using CRC counters, optic levels and patch tests.

Incorrect Answers

This misconception choice fits a different situation: A multicast feed overwhelms user ports that did not subscribe to its group. It does not resolve the stated failure mode. For this case, the decisive misconception choice is to increasing QoS priority to hide a damaged fiber link.

Question 495

Before changing switch configuration, an engineer investigates: A network interface experiences high frame errors at peak load but no routing alarms. Which FIRST check is most useful for isolating the cause?

Inspect queue counters, DSCP classes and utilization timelines
Review CPU telemetry, process logs and NAE agent event times
Test representative packet sizes and inspect interface MTU values
Review interface FCS counters, optics power and cable plant results

Explanation

Correct Answer

Review interface FCS counters, optics power and cable plant results. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that frame integrity errors often reveal physical problems rather than route policy.

Question 496

An implementation change is planned for: A network interface experiences high frame errors at peak load but no routing alarms. Which preventive control BEST reduces unnecessary outage and security risk?

Set capacity and drop thresholds for priority applications
Retain historical error baselines and test optical paths
Capacity-plan using measured traffic mix rather than theoretical link sum
Plan querier reachability and membership aging tests

Explanation

Correct Answer

Retain historical error baselines and test optical paths. This safeguard is appropriate before the change to diagnose physical layer errors using CRC counters, optic levels and patch tests; it reduces exposure to the mistake of increasing QoS priority to hide a damaged fiber link.

Incorrect Answers

This prevention choice fits a different situation: Video traffic suffers delay only when backups saturate an interbuilding uplink. It does not resolve the stated failure mode. For this case, the decisive prevention choice is to retain historical error baselines and test optical paths.
