HP HPE7-A08 Practice Test 69

Question 680

An HPE Aruba Networking engineer faces this wired-network scenario: A compliance tool needs read-only AOS-CX configuration inventory across firmware editions. Which implementation action BEST addresses the requirement?

  1. Use idempotent desired-state changes with explicit device targeting and prechange diffs
  2. Use version-aware AOS-CX REST API requests with least-privileged authenticated access
  3. Compare authenticated API reads to the approved policy baseline and handle errors explicitly
  4. Use a versioned golden configuration template and record approved deviations

Explanation

Correct Answer

B:

REST API routes and fields are versioned and depend on switch support. The targeted implementation is to use version-aware AOS-CX REST API requests with least-privileged authenticated access. The deployment succeeds when the audit retrieves the intended properties on each supported target without writes.

Incorrect Answers

A:

This implementation choice fits a different situation: An automation job must update access VLANs on a subset of managed switches. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to use version-aware AOS-CX REST API requests with least-privileged authenticated access.

C:

This implementation choice fits a different situation: An API-based audit reports success yet some switches have divergent security settings. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to use version-aware AOS-CX REST API requests with least-privileged authenticated access.

D:

This implementation 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 implementation choice is to use version-aware AOS-CX REST API requests with least-privileged authenticated access.

Question 681

After implementing the approved change — Use version-aware AOS-CX REST API requests with least-privileged authenticated access — for this scenario: A compliance tool needs read-only AOS-CX configuration inventory across firmware editions. Which observed result BEST verifies the outcome?

  1. The report flags each true deviation with device, version and expected value
  2. Repeated jobs converge on the approved state without duplicate modifications
  3. The event record identifies a reproducible transition and candidate cause
  4. The audit retrieves the intended properties on each supported target without writes

Explanation

Correct Answer

D:

The audit retrieves the intended properties on each supported target without writes. This is the observable acceptance evidence for the decision to use version-aware AOS-CX REST API requests with least-privileged authenticated access. It demonstrates the principle that rEST API routes and fields are versioned and depend on switch support.

Incorrect Answers

A:

This verification choice fits a different situation: An API-based audit reports success yet some switches have divergent security settings. It does not resolve the stated failure mode. For this case, the decisive verification choice is to the audit retrieves the intended properties on each supported target without writes.

B:

This verification choice fits a different situation: An automation job must update access VLANs on a subset of managed switches. It does not resolve the stated failure mode. For this case, the decisive verification choice is to the audit retrieves the intended properties on each supported target without writes.

C:

For this case, the decisive verification choice is to the audit retrieves the intended properties on each supported target without writes.

Question 682

An HPE Aruba Networking design review examines: A compliance tool needs read-only AOS-CX configuration inventory across firmware editions. Which technical principle BEST explains the required approach?

  1. Automated compliance checks need evidence of both successful retrieval and comparison
  2. REST API routes and fields are versioned and depend on switch support
  3. Idempotent configuration automation reduces drift and unexpected retries
  4. Automation templates should be tested and limited in scope

Explanation

Correct Answer

B:

REST API routes and fields are versioned and depend on switch support. The case therefore calls for this specifically controlled action: use version-aware AOS-CX REST API requests with least-privileged authenticated access. The acceptance evidence is that the audit retrieves the intended properties on each supported target without writes.

Incorrect Answers

A:

This principle choice fits a different situation: An API-based audit reports success yet some switches have divergent security settings. It does not resolve the stated failure mode. For this case, the decisive principle choice is to rEST API routes and fields are versioned and depend on switch support.

C:

This principle choice fits a different situation: An automation job must update access VLANs on a subset of managed switches. It does not resolve the stated failure mode. For this case, the decisive principle choice is to rEST API routes and fields are versioned and depend on switch support.

D:

This principle 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 principle choice is to rEST API routes and fields are versioned and depend on switch support.

Question 683

A risk review for the following wired-network case asks what should be avoided: A compliance tool needs read-only AOS-CX configuration inventory across firmware editions. Which assumption creates the GREATEST implementation risk?

  1. Marking every HTTP success response as proof the policy is compliant
  2. Pushing a broad write to every device because one switch needs repair
  3. Treating a stack with no standby as fully redundant
  4. Hard-coding a deprecated API version for every firmware release

Explanation

Correct Answer

D:

Hard-coding a deprecated API version for every firmware release. That shortcut fails because rEST API routes and fields are versioned and depend on switch support. Instead, the appropriate approach is to use version-aware AOS-CX REST API requests with least-privileged authenticated access.

Incorrect Answers

A:

This misconception choice fits a different situation: An API-based audit reports success yet some switches have divergent security settings. It does not resolve the stated failure mode. For this case, the decisive misconception choice is to hard-coding a deprecated API version for every firmware release.

B:

This misconception choice fits a different situation: An automation job must update access VLANs on a subset of managed switches. It does not resolve the stated failure mode. For this case, the decisive misconception choice is to hard-coding a deprecated API version for every firmware release.

C:

This misconception 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 misconception choice is to hard-coding a deprecated API version for every firmware release.

Question 684

Before changing switch configuration, an engineer investigates: A compliance tool needs read-only AOS-CX configuration inventory across firmware editions. Which FIRST check is most useful for isolating the cause?

  1. Compare rendered desired state, target inventory and current device config
  2. Inspect the switch REST supported versions and authorization response
  3. Inspect response status, missing fields, parsing and policy diff details
  4. Audit active local accounts, secrets storage and AAA fallback policy

Explanation

Correct Answer

B:

Inspect the switch REST supported versions and authorization response. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that rEST API routes and fields are versioned and depend on switch support.

Incorrect Answers

A:

This diagnostic choice fits a different situation: An automation job must update access VLANs on a subset of managed switches. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to inspect the switch REST supported versions and authorization response.

C:

This diagnostic choice fits a different situation: An API-based audit reports success yet some switches have divergent security settings. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to inspect the switch REST supported versions and authorization response.

D:

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 inspect the switch REST supported versions and authorization response.

Question 685

An implementation change is planned for: A compliance tool needs read-only AOS-CX configuration inventory across firmware editions. Which preventive control BEST reduces unnecessary outage and security risk?

  1. Require narrow scope and approval before automation writes
  2. Log per-device evidence and fail closed on incomplete API responses
  3. Pilot a sample port and require diff approval for wider use
  4. Test API compatibility in a lab and store credentials securely

Explanation

Correct Answer

D:

Test API compatibility in a lab and store credentials securely. This safeguard is appropriate before the change to use version-aware AOS-CX REST API requests with least-privileged authenticated access; it reduces exposure to the mistake of hard-coding a deprecated API version for every firmware release.

Incorrect Answers

A:

This prevention choice fits a different situation: An automation job must update access VLANs on a subset of managed switches. It does not resolve the stated failure mode. For this case, the decisive prevention choice is to test API compatibility in a lab and store credentials securely.

B:

This prevention choice fits a different situation: An API-based audit reports success yet some switches have divergent security settings. It does not resolve the stated failure mode. For this case, the decisive prevention choice is to test API compatibility in a lab and store credentials securely.

C:

This prevention 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 prevention choice is to test API compatibility in a lab and store credentials securely.

Question 686

A first repair attempt for this situation failed: A compliance tool needs read-only AOS-CX configuration inventory across firmware editions. The review found the mistaken approach of hard-coding a deprecated API version for every firmware release. Which targeted recovery action BEST restores the intended design?

  1. Fix the parser or authorization scope and rerun the targeted compliance comparison
  2. Revert unintended modifications and rerun with validated target selection
  3. Select the advertised compatible API path and rerun the read-only audit
  4. Correct collector connectivity and sample parameters then rerun analysis

Explanation

Correct Answer

C:

Select the advertised compatible API path and rerun the read-only audit. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when the audit retrieves the intended properties on each supported target without writes.

Incorrect Answers

A:

This remediation choice fits a different situation: An API-based audit reports success yet some switches have divergent security settings. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to select the advertised compatible API path and rerun the read-only audit.

B:

This remediation choice fits a different situation: An automation job must update access VLANs on a subset of managed switches. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to select the advertised compatible API path and rerun the read-only audit.

D:

This remediation choice fits a different situation: An engineering group needs visibility into traffic mixes rather than only aggregate port utilization. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to select the advertised compatible API path and rerun the read-only audit.

Question 687

An HPE Aruba Networking engineer faces this wired-network scenario: An automation job must update access VLANs on a subset of managed switches. Which implementation action BEST addresses the requirement?
