Question 640

The HPE AOS-CX switching case is: A Central group reports compliant while two devices retain documented overrides that were never reviewed after the last change. Select TWO: a corrective switching action and separate evidence that the correction worked. (Select TWO.)

  1. Archive approved AOS-CX running and startup configurations with device identity, version, date and access controls so changes remain traceable.
  2. A group inventory reports the expected installed version for each reachable switch and the configured services pass smoke tests.
  3. Compare switch running state with an approved intended configuration on a controlled schedule and investigate meaningful policy drift.
  4. Validate supported hardware images, relevant feature behavior, VSF/VSX upgrade sequences and maintenance windows before switching firmware.
  5. A comparison report identifies all unauthorized changes and confirms approved exceptions remain documented without false matches.

Explanation

Correct Answers

C:

The targeted correction for A Central group reports compliant while two devices retain documented overrides that were never reviewed after the last change is: Compare switch running state with an approved intended configuration on a controlled schedule and investigate meaningful policy drift. It reduces the risk that undetected local overrides and drift can accumulate across branches and weaken segmentation or network reliability.

E:

A separate operational validation for A Central group reports compliant while two devices retain documented overrides that were never reviewed after the last change is: A comparison report identifies all unauthorized changes and confirms approved exceptions remain documented without false matches. It proves intended behavior instead of accepting configuration presence alone.

Incorrect Answers

A:

This alternative concerns switch configuration archive and baseline governance; its associated risk is: A configuration backup with no device/version identity can restore an incorrect VLAN or security baseline during a major outage. The observed case A Central group reports compliant while two devices retain documented overrides that were never reviewed after the last change requires the more specific scheduled configuration audit and desired-state compliance control. The targeted action is: Compare switch running state with an approved intended configuration on a controlled schedule and investigate meaningful policy drift.

B:

This alternative concerns central firmware and group compliance rollouts; its associated risk is: A queued or blocked Central operation can leave some switches on old software while dashboards imply the deployment finished. The observed case A Central group reports compliant while two devices retain documented overrides that were never reviewed after the last change requires the more specific scheduled configuration audit and desired-state compliance control. The targeted action is: Compare switch running state with an approved intended configuration on a controlled schedule and investigate meaningful policy drift.

D:

This alternative concerns safe firmware release and feature compatibility planning; its associated risk is: Upgrading incompatible software across peer switches can create avoidable outages and leave routing or stacking features unavailable. The observed case A Central group reports compliant while two devices retain documented overrides that were never reviewed after the last change requires the more specific scheduled configuration audit and desired-state compliance control. The targeted action is: Compare switch running state with an approved intended configuration on a controlled schedule and investigate meaningful policy drift.

Question 641

An HPE Aruba Networking engineer observes: A VSX distribution pair is upgraded simultaneously despite a change plan that requires maintaining one forwarding peer. The corrective solution must keep intended connectivity, segmentation, and operational resilience. Which change best addresses the observed switching requirement?

  1. Compare switch running state with an approved intended configuration on a controlled schedule and investigate meaningful policy drift.
  2. Verify that approved configuration was saved to startup, back up the previous state and test recovery before restarting a switch.
  3. Validate supported hardware images, relevant feature behavior, VSF/VSX upgrade sequences and maintenance windows before switching firmware.
  4. Archive approved AOS-CX running and startup configurations with device identity, version, date and access controls so changes remain traceable.

Explanation

Correct Answer

C:

The decisive observed condition is: A VSX distribution pair is upgraded simultaneously despite a change plan that requires maintaining one forwarding peer. The appropriate switching action is: Validate supported hardware images, relevant feature behavior, VSF/VSX upgrade sequences and maintenance windows before switching firmware. It addresses the risk that upgrading incompatible software across peer switches can create avoidable outages and leave routing or stacking features unavailable. Confirm with: A staged representative upgrade retains management, topology and intended forwarding with a tested rollback image.

Incorrect Answers

A:

This alternative concerns scheduled configuration audit and desired-state compliance; its associated risk is: Undetected local overrides and drift can accumulate across branches and weaken segmentation or network reliability.

The targeted action is: Validate supported hardware images, relevant feature behavior, VSF/VSX upgrade sequences and maintenance windows before switching firmware.

B:

This alternative concerns config restore and startup persistence protection; its associated risk is: An unsaved edit disappears on reboot while a mistakenly persisted temporary setting survives beyond its intended scope. The observed case A VSX distribution pair is upgraded simultaneously despite a change plan that requires maintaining one forwarding peer requires the more specific safe firmware release and feature compatibility planning control.

Question 642

An engineer investigates: A VSX distribution pair is upgraded simultaneously despite a change plan that requires maintaining one forwarding peer. What acceptance evidence most directly demonstrates the correction succeeded?

  1. After a controlled reboot the expected interface, VLAN and management state persists and a previous baseline can be restored.
  2. A restore rehearsal applies the right archived configuration to a matching test device and passes a diff against approved policy.
  3. A staged representative upgrade retains management, topology and intended forwarding with a tested rollback image.
  4. A comparison report identifies all unauthorized changes and confirms approved exceptions remain documented without false matches.

Explanation

Correct Answer

C:

The independent acceptance evidence for A VSX distribution pair is upgraded simultaneously despite a change plan that requires maintaining one forwarding peer is: A staged representative upgrade retains management, topology and intended forwarding with a tested rollback image. It tests whether the team has actually implemented: Validate supported hardware images, relevant feature behavior, VSF/VSX upgrade sequences and maintenance windows before switching firmware. An enabled interface or saved configuration by itself is not evidence of complete service recovery.

Question 643

An HPE Aruba Networking engineer observes: A stack controller receives an image without confirming the members' hardware support and software compatibility. The corrective solution must keep intended connectivity, segmentation, and operational resilience. What is the most defensible operational action before closing the network change?

  1. Archive approved AOS-CX running and startup configurations with device identity, version, date and access controls so changes remain traceable.
  2. Verify that approved configuration was saved to startup, back up the previous state and test recovery before restarting a switch.
  3. Use a controlled switching change ticket with owner, impacted VLANs, business window, acceptance tests and rollback trigger.
  4. Validate supported hardware images, relevant feature behavior, VSF/VSX upgrade sequences and maintenance windows before switching firmware.
