HP HPE7-A08 Practice Test 70

Question 690

A risk review for the following wired-network case asks what should be avoided: An automation job must update access VLANs on a subset of managed switches. Which assumption creates the GREATEST implementation risk?

Marking every HTTP success response as proof the policy is compliant
Pushing a broad write to every device because one switch needs repair
Hard-coding a deprecated API version for every firmware release
Assuming a one-time installation acceptance prevents later configuration drift

Explanation

Correct Answer

Pushing a broad write to every device because one switch needs repair. That shortcut fails because idempotent configuration automation reduces drift and unexpected retries. Instead, the appropriate approach is to use idempotent desired-state changes with explicit device targeting and prechange diffs.

Incorrect Answers

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 pushing a broad write to every device because one switch needs repair.

Question 691

Before changing switch configuration, an engineer investigates: An automation job must update access VLANs on a subset of managed switches. Which FIRST check is most useful for isolating the cause?

Inspect the switch REST supported versions and authorization response
Inspect response status, missing fields, parsing and policy diff details
Inspect VSX brief state, ISL interface and keepalive reachability
Compare rendered desired state, target inventory and current device config

Explanation

Correct Answer

Compare rendered desired state, target inventory and current device config. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that idempotent configuration automation reduces drift and unexpected retries.

Question 692

An implementation change is planned for: An automation job must update access VLANs on a subset of managed switches. Which preventive control BEST reduces unnecessary outage and security risk?

Log per-device evidence and fail closed on incomplete API responses
Require narrow scope and approval before automation writes
Test API compatibility in a lab and store credentials securely
Verify required telemetry data fields in a staged group

Explanation

Correct Answer

Require narrow scope and approval before automation writes. This safeguard is appropriate before the change to use idempotent desired-state changes with explicit device targeting and prechange diffs; it reduces exposure to the mistake of pushing a broad write to every device because one switch needs repair.

Question 693

A first repair attempt for this situation failed: An automation job must update access VLANs on a subset of managed switches. The review found the mistaken approach of pushing a broad write to every device because one switch needs repair. Which targeted recovery action BEST restores the intended design?

Revert unintended modifications and rerun with validated target selection
Select the advertised compatible API path and rerun the read-only audit
Fix the parser or authorization scope and rerun the targeted compliance comparison
Repair the indicated peer channel before clearing the VSX incident

Explanation

Correct Answer

Revert unintended modifications and rerun with validated target selection. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when repeated jobs converge on the approved state without duplicate modifications.

Question 694

An HPE Aruba Networking engineer faces this wired-network scenario: An API-based audit reports success yet some switches have divergent security settings. Which implementation action BEST addresses the requirement?

Use idempotent desired-state changes with explicit device targeting and prechange diffs
Compare authenticated API reads to the approved policy baseline and handle errors explicitly
Use version-aware AOS-CX REST API requests with least-privileged authenticated access
Use an AOS-CX NAE monitoring agent or suitable telemetry to watch correlated events

Explanation

Correct Answer

Automated compliance checks need evidence of both successful retrieval and comparison. The targeted implementation is to compare authenticated API reads to the approved policy baseline and handle errors explicitly. The deployment succeeds when the report flags each true deviation with device, version and expected value.

Question 695

After implementing the approved change — Compare authenticated API reads to the approved policy baseline and handle errors explicitly — for this scenario: An API-based audit reports success yet some switches have divergent security settings. Which observed result BEST verifies the outcome?

The audit retrieves the intended properties on each supported target without writes
Repeated jobs converge on the approved state without duplicate modifications
An intentional interface-down test produces one correct actionable alert
The report flags each true deviation with device, version and expected value

Explanation

The report flags each true deviation with device, version and expected value. This is the observable acceptance evidence for the decision to compare authenticated API reads to the approved policy baseline and handle errors explicitly. It demonstrates the principle that automated compliance checks need evidence of both successful retrieval and comparison.

Question 696

An HPE Aruba Networking design review examines: An API-based audit reports success yet some switches have divergent security settings. Which technical principle BEST explains the required approach?

REST API routes and fields are versioned and depend on switch support
Automated compliance checks need evidence of both successful retrieval and comparison
Idempotent configuration automation reduces drift and unexpected retries
Routing stability requires time-correlated evidence rather than a single snapshot

Explanation

Correct Answer

Automated compliance checks need evidence of both successful retrieval and comparison. The case therefore calls for this specifically controlled action: compare authenticated API reads to the approved policy baseline and handle errors explicitly. The acceptance evidence is that the report flags each true deviation with device, version and expected value.
