HP HPE7-A08 Practice Test 36

Question 350

A first repair attempt for this situation failed: A network management tool needs to read interface status from AOS-CX switches. The review found the mistaken approach of embedding administrator credentials in the collector's source code. Which targeted recovery action BEST restores the intended design?

  1. Fix RADIUS-to-switch role mapping and force controlled reauthentication
  2. Repair the telemetry policy and reassign alert routing to the right team
  3. Correct the API path or token scope then rerun read-only telemetry tests
  4. Fix duplicate event correlation and verify incident suppression logic

Explanation

Correct Answer

C:

Correct the API path or token scope then rerun read-only telemetry tests. This addresses the observed risk rather than hiding its symptoms. Confirm the repair when the integration returns accurate link and counters without granting configuration writes.

Incorrect Answers

A:

This remediation choice fits a different situation: A campus uses ClearPass to assign different roles to employees and contractors. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to correct the API path or token scope then rerun read-only telemetry tests.

B:

This remediation choice fits a different situation: A switch inventory in Central lacks useful health alerts for a regional operations team. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to correct the API path or token scope then rerun read-only telemetry tests.

D:

This remediation choice fits a different situation: An operations team wants a switch event to trigger external incident handling. It does not resolve the stated failure mode. For this case, the decisive remediation choice is to correct the API path or token scope then rerun read-only telemetry tests.

Question 351

An HPE Aruba Networking engineer faces this wired-network scenario: An operations team wants a switch event to trigger external incident handling. Which implementation action BEST addresses the requirement?

  1. Integrate Central switch monitoring with the approved site and alert workflow
  2. Integrate port-access RADIUS attributes and role enforcement with tested ClearPass policy
  3. Use authorized AOS-CX REST API access with supported firmware API version and endpoint permissions
  4. Integrate supported NAE events, logs or alert webhooks into a controlled ticket workflow

Explanation

Correct Answer

D:

Event-driven integrations should minimize duplicates and preserve auditability. The targeted implementation is to integrate supported NAE events, logs or alert webhooks into a controlled ticket workflow. The deployment succeeds when a known interface-failure alert creates one correlated incident with device details.

Incorrect Answers

A:

This implementation choice fits a different situation: A switch inventory in Central lacks useful health alerts for a regional operations team. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to integrate supported NAE events, logs or alert webhooks into a controlled ticket workflow.

B:

This implementation choice fits a different situation: A campus uses ClearPass to assign different roles to employees and contractors. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to integrate supported NAE events, logs or alert webhooks into a controlled ticket workflow.

C:

This implementation choice fits a different situation: A network management tool needs to read interface status from AOS-CX switches. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to integrate supported NAE events, logs or alert webhooks into a controlled ticket workflow.

Question 352

After implementing the approved change — Integrate supported NAE events, logs or alert webhooks into a controlled ticket workflow — for this scenario: An operations team wants a switch event to trigger external incident handling. Which observed result BEST verifies the outcome?

  1. The integration returns accurate link and counters without granting configuration writes
  2. A known interface-failure alert creates one correlated incident with device details
  3. Employees and contractors receive distinct authorized access on the same physical port
  4. The operations team receives device-state changes with correct switch identity

Explanation

Correct Answer

B:

A known interface-failure alert creates one correlated incident with device details. This is the observable acceptance evidence for the decision to integrate supported NAE events, logs or alert webhooks into a controlled ticket workflow. It demonstrates the principle that event-driven integrations should minimize duplicates and preserve auditability.

Incorrect Answers

A:

This verification choice fits a different situation: A network management tool needs to read interface status from AOS-CX switches. It does not resolve the stated failure mode. For this case, the decisive verification choice is to a known interface-failure alert creates one correlated incident with device details.

C:

This verification choice fits a different situation: A campus uses ClearPass to assign different roles to employees and contractors. It does not resolve the stated failure mode. For this case, the decisive verification choice is to a known interface-failure alert creates one correlated incident with device details.

D:

For this case, the decisive verification choice is to a known interface-failure alert creates one correlated incident with device details.

Question 353

An HPE Aruba Networking design review examines: An operations team wants a switch event to trigger external incident handling. Which technical principle BEST explains the required approach?

  1. Programmatic integration requires explicit authentication and least privilege
  2. Management integration should preserve source identity and alert ownership
  3. Identity decisions and switch enforcement must agree on role attributes
  4. Event-driven integrations should minimize duplicates and preserve auditability

Explanation

Correct Answer

D:

Event-driven integrations should minimize duplicates and preserve auditability. The case therefore calls for this specifically controlled action: integrate supported NAE events, logs or alert webhooks into a controlled ticket workflow. The acceptance evidence is that a known interface-failure alert creates one correlated incident with device details.

Incorrect Answers

A:

This principle choice fits a different situation: A network management tool needs to read interface status from AOS-CX switches. It does not resolve the stated failure mode. For this case, the decisive principle choice is to event-driven integrations should minimize duplicates and preserve auditability.

B:

This principle choice fits a different situation: A switch inventory in Central lacks useful health alerts for a regional operations team. It does not resolve the stated failure mode. For this case, the decisive principle choice is to event-driven integrations should minimize duplicates and preserve auditability.

C:

This principle choice fits a different situation: A campus uses ClearPass to assign different roles to employees and contractors. It does not resolve the stated failure mode. For this case, the decisive principle choice is to event-driven integrations should minimize duplicates and preserve auditability.

Question 354

A risk review for the following wired-network case asks what should be avoided: An operations team wants a switch event to trigger external incident handling. Which assumption creates the GREATEST implementation risk?

  1. Assuming a successful RADIUS accept always assigns the intended policy
  2. Treating every transient link flap as a new unrelated major incident
  3. Assuming device onboarding alone configures all needed operations notifications
  4. Embedding administrator credentials in the collector's source code

Explanation

Correct Answer

B:

Treating every transient link flap as a new unrelated major incident. That shortcut fails because event-driven integrations should minimize duplicates and preserve auditability. Instead, the appropriate approach is to integrate supported NAE events, logs or alert webhooks into a controlled ticket workflow.

Incorrect Answers

A:

This misconception choice fits a different situation: A campus uses ClearPass to assign different roles to employees and contractors. It does not resolve the stated failure mode. For this case, the decisive misconception choice is to treating every transient link flap as a new unrelated major incident.

C:

This misconception choice fits a different situation: A switch inventory in Central lacks useful health alerts for a regional operations team. It does not resolve the stated failure mode. For this case, the decisive misconception choice is to treating every transient link flap as a new unrelated major incident.

D:

This misconception choice fits a different situation: A network management tool needs to read interface status from AOS-CX switches. It does not resolve the stated failure mode. For this case, the decisive misconception choice is to treating every transient link flap as a new unrelated major incident.

Question 355

Before changing switch configuration, an engineer investigates: An operations team wants a switch event to trigger external incident handling. Which FIRST check is most useful for isolating the cause?

  1. Inspect HTTPS access, REST version and authorization scope
  2. Inspect Central group, telemetry reachability and alert settings
  3. Inspect returned attributes, switch role mapping and authorization logs
  4. Inspect NAE agent conditions, event IDs and message delivery

Explanation

Correct Answer

D:

Inspect NAE agent conditions, event IDs and message delivery. This first check isolates the relevant mechanism without an untested configuration change. It tests the rule that event-driven integrations should minimize duplicates and preserve auditability.

Incorrect Answers

A:

This diagnostic choice fits a different situation: A network management tool needs to read interface status from AOS-CX switches. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to inspect NAE agent conditions, event IDs and message delivery.

B:

This diagnostic choice fits a different situation: A switch inventory in Central lacks useful health alerts for a regional operations team. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to inspect NAE agent conditions, event IDs and message delivery.

C:

This diagnostic choice fits a different situation: A campus uses ClearPass to assign different roles to employees and contractors. It does not resolve the stated failure mode. For this case, the decisive diagnostic choice is to inspect NAE agent conditions, event IDs and message delivery.

Question 356

An implementation change is planned for: An operations team wants a switch event to trigger external incident handling. Which preventive control BEST reduces unnecessary outage and security risk?

  1. Store secrets securely and pin a tested compatible API route
  2. Use debounce and correlation rules in the alert workflow
  3. Validate representative endpoint identities before full roll-out
  4. Test an alert on a staging device and document its recipient

Explanation

Correct Answer

B:

Use debounce and correlation rules in the alert workflow. This safeguard is appropriate before the change to integrate supported NAE events, logs or alert webhooks into a controlled ticket workflow; it reduces exposure to the mistake of treating every transient link flap as a new unrelated major incident.

Question 358

An HPE Aruba Networking engineer faces this wired-network scenario: A user host has an IP address in the wrong subnet and cannot reach its gateway. Which implementation action BEST addresses the requirement?

  1. Identify the relevant ACL or role policy drop on the forwarding path
  2. Identify the host mask and gateway mismatch before changing switch routing
  3. Identify likely optic or fiber-layer faults using counters and optical diagnostics
  4. Identify ISL and keepalive states before modifying the peer's forwarding behavior

Explanation

Correct Answer

B:

Endpoint addressing must match its VLAN and gateway network. The targeted implementation is to identify the host mask and gateway mismatch before changing switch routing. The deployment succeeds when correcting the endpoint subnet restores gateway reachability.

Incorrect Answers

A:

This implementation choice fits a different situation: Only a restricted subnet is unreachable while all ordinary traffic passes. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to identify the host mask and gateway mismatch before changing switch routing.

C:

This implementation choice fits a different situation: A fiber connection logs high FCS errors and periodically loses carrier. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to identify the host mask and gateway mismatch before changing switch routing.

D:

This implementation choice fits a different situation: A VSX pair loses downstream LAG forwarding after an ISL interruption. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to identify the host mask and gateway mismatch before changing switch routing.

Question 359

After implementing the approved change — Identify the host mask and gateway mismatch before changing switch routing — for this scenario: A user host has an IP address in the wrong subnet and cannot reach its gateway. Which observed result BEST verifies the outcome?

  1. OSPF neighbors reach the intended state and routes appear after repair
  2. The port state changes when deliberately enabled and passes traffic
  3. The matched members become active after peer settings are aligned
  4. Correcting the endpoint subnet restores gateway reachability

Explanation

Correct Answer

D:

Correcting the endpoint subnet restores gateway reachability. This is the observable acceptance evidence for the decision to identify the host mask and gateway mismatch before changing switch routing. It demonstrates the principle that endpoint addressing must match its VLAN and gateway network.

C:

This verification choice fits a different situation: A bundle reports suspended members while each individual port appears link-up. It does not resolve the stated failure mode. For this case, the decisive verification choice is to correcting the endpoint subnet restores gateway reachability.

Question 360

An HPE Aruba Networking design review examines: A user host has an IP address in the wrong subnet and cannot reach its gateway. Which technical principle BEST explains the required approach?

  1. OSPF control-plane compatibility differs from simple IP reachability
  2. Endpoint addressing must match its VLAN and gateway network
  3. CRC and physical alarms provide stronger link-health evidence than a lit LED
  4. An operational LAG depends on compatible partner identity and settings

Explanation

Correct Answer
