HP HPE7-A08 Practice Test 61

Question 600

Before changing switch configuration, an engineer investigates: An operations team wants to optimize maintenance without losing baseline network behavior. Which FIRST check is most useful for isolating the cause?

Audit active local accounts, secrets storage and AAA fallback policy
Review historical diffs, approved changes and open exception tickets
Compare switch configs against role-specific baseline
Inspect audit logs, commit records and change tickets

Explanation

Correct Answer

Review historical diffs, approved changes and open exception tickets. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that continuous configuration assurance is a lifecycle process.

Incorrect Answers

This diagnostic choice fits a different situation: A multi-site deployment retains unused local administrative credentials after automation onboarding. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to review historical diffs, approved changes and open exception tickets.

This diagnostic choice fits a different situation: A security audit detects configuration differences among supposedly identical branch switches. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to review historical diffs, approved changes and open exception tickets.

This diagnostic choice fits a different situation: An engineer updates access policies but no one can identify who changed the configuration. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to review historical diffs, approved changes and open exception tickets.

Question 601

An implementation change is planned for: An operations team wants to optimize maintenance without losing baseline network behavior. Which preventive control BEST reduces unnecessary outage and security risk?

Test recovery of a representative switch before approving the backup process
Use secret vaulting and rotation with a tested emergency access procedure
Use separate identities and centralized authorization for configuration writes
Schedule recurring policy comparisons and maintenance owner review

Explanation

Correct Answer

Schedule recurring policy comparisons and maintenance owner review. This safeguard is appropriate before the change to define periodic configuration compliance checks and an exception-remediation cycle; it reduces exposure to the mistake of assuming a one-time installation acceptance prevents later configuration drift.

Incorrect Answers

This prevention choice fits a different situation: An operations team cannot restore a replaced switch after an unexpected failure. It does not resolve the stated failure mode. For this case, the decisive prevention choice is to schedule recurring policy comparisons and maintenance owner review.

Question 602

A first repair attempt for this situation failed: An operations team wants to optimize maintenance without losing baseline network behavior. The review found the mistaken approach of assuming a one-time installation acceptance prevents later configuration drift. Which targeted recovery action BEST restores the intended design?

Revert the unintended generated change and rerender with corrected scope
Restore approved differences while retaining documented site exceptions
Apply the least disruptive approved fix and confirm baseline reconciliation
Restore the supported previous image or peer sequence if acceptance fails

Explanation

Correct Answer

Apply the least disruptive approved fix and confirm baseline reconciliation. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when drift findings close only after a validated correction and follow-up check.

Incorrect Answers

This remediation choice fits a different situation: Network teams need a safe process for repeated port provisioning. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to apply the least disruptive approved fix and confirm baseline reconciliation.

Question 603

An HPE Aruba Networking engineer faces this wired-network scenario: A central operations dashboard lacks alerts when a core link goes down. Which implementation action BEST addresses the requirement?

Correlate route-neighbor state changes with logging, interface health and planned jobs
Inspect per-class queue drops and microburst evidence instead of relying solely on averages
Use sampled flow telemetry such as supported sFlow reporting to an approved collector
Collect appropriate interface state events and route them through the notification system

Explanation

Correct Answer

Link-state telemetry needs alerting and correct ownership to be operationally useful. The targeted implementation is to collect appropriate interface state events and route them through the notification system. The deployment succeeds when an intentional interface-down test produces one correct actionable alert.

Incorrect Answers

It does not resolve the stated failure mode. For this case, the decisive implementation choice is to collect appropriate interface state events and route them through the notification system.

Question 604

After implementing the approved change — Collect appropriate interface state events and route them through the notification system — for this scenario: A central operations dashboard lacks alerts when a core link goes down. Which observed result BEST verifies the outcome?

Congestion events align with queue depth even when five-minute rates look normal
An intentional interface-down test produces one correct actionable alert
The event record identifies a reproducible transition and candidate cause
The collector identifies key traffic sources while respecting sampling limitations

Explanation

Correct Answer

An intentional interface-down test produces one correct actionable alert. This is the observable acceptance evidence for the decision to collect appropriate interface state events and route them through the notification system. It demonstrates the principle that link-state telemetry needs alerting and correct ownership to be operationally useful.

Incorrect Answers

Question 605

An HPE Aruba Networking design review examines: A central operations dashboard lacks alerts when a core link goes down. Which technical principle BEST explains the required approach?

Client authorization health requires protocol and role telemetry
Routing stability requires time-correlated evidence rather than a single snapshot
Hardware environmental telemetry is relevant to switch reliability
Link-state telemetry needs alerting and correct ownership to be operationally useful

Explanation

Correct Answer

Link-state telemetry needs alerting and correct ownership to be operationally useful. The case therefore calls for this specifically controlled action: collect appropriate interface state events and route them through the notification system. The acceptance evidence is that an intentional interface-down test produces one correct actionable alert.

Incorrect Answers

Question 606

A risk review for the following wired-network case asks what should be avoided: A central operations dashboard lacks alerts when a core link goes down. Which assumption creates the GREATEST implementation risk?

Calling both switches healthy simply because both respond to SSH
Treating the absence of a helpdesk ticket as proof no link fault occurred
Reporting only link state while ignoring port authentication failure events
Clearing counters repeatedly so long-term faults vanish from reports

Explanation

Correct Answer

Treating the absence of a helpdesk ticket as proof no link fault occurred. That shortcut fails because link-state telemetry needs alerting and correct ownership to be operationally useful. Instead, the appropriate approach is to collect appropriate interface state events and route them through the notification system.

Incorrect Answers

Set alert severity and suppression according to service impact
Set alert granularity and preserve burst-focused diagnostics
Set temperature thresholds and plan cooling maintenance

Explanation

Correct Answer
