Question 670

The HPE AOS-CX switching case is: A large group receives a new image but no one validates the actual routing and authentication state afterward. Which TWO choices together provide the targeted remedy and independent validation? (Select TWO.)

  1. Use supported Central scheduling, device groups, firmware compliance and post-upgrade validation instead of treating a portal job as proof of healthy operation.
  2. A separate engineer follows the updated runbook to locate, inspect and safely restore an affected switch service.
  3. Use a controlled switching change ticket with owner, impacted VLANs, business window, acceptance tests and rollback trigger.
  4. Compare switch running state with an approved intended configuration on a controlled schedule and investigate meaningful policy drift.
  5. A group inventory reports the expected installed version for each reachable switch and the configured services pass smoke tests.

Explanation

Correct Answers

A:

The targeted correction for A large group receives a new image but no one validates the actual routing and authentication state afterward is: Use supported Central scheduling, device groups, firmware compliance and post-upgrade validation instead of treating a portal job as proof of healthy operation. It reduces the risk that a queued or blocked Central operation can leave some switches on old software while dashboards imply the deployment finished.

E:

A separate operational validation for A large group receives a new image but no one validates the actual routing and authentication state afterward is: A group inventory reports the expected installed version for each reachable switch and the configured services pass smoke tests. It proves intended behavior instead of accepting configuration presence alone.

Incorrect Answers

B:

This alternative concerns handoff documentation and operational runbook maintenance; its associated risk is: Unrecorded VLAN or peer-role changes can turn routine incidents into extended outages and make compliance review unreliable. The observed case A large group receives a new image but no one validates the actual routing and authentication state afterward requires the more specific central firmware and group compliance rollouts control. The targeted action is: Use supported Central scheduling, device groups, firmware compliance and post-upgrade validation instead of treating a portal job as proof of healthy operation.

C:

This alternative concerns maintenance window communication and change approval; its associated risk is: A technically correct change performed without coordination can interrupt critical services and prevent recovery within the approved outage allowance. The observed case A large group receives a new image but no one validates the actual routing and authentication state afterward requires the more specific central firmware and group compliance rollouts control. The targeted action is: Use supported Central scheduling, device groups, firmware compliance and post-upgrade validation instead of treating a portal job as proof of healthy operation.

D:

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 observed case A large group receives a new image but no one validates the actual routing and authentication state afterward requires the more specific central firmware and group compliance rollouts control. The targeted action is: Use supported Central scheduling, device groups, firmware compliance and post-upgrade validation instead of treating a portal job as proof of healthy operation.

Question 671

An HPE Aruba Networking engineer observes: An automation schedule restarts every access switch simultaneously despite planned staged client availability. The corrective solution must keep intended connectivity, segmentation, and operational resilience. Which response best satisfies the technical requirement without disrupting unrelated traffic?

  1. Maintain switch inventory, topology, configuration standards, service owners and recovery checks after every approved network change.
  2. Use a controlled switching change ticket with owner, impacted VLANs, business window, acceptance tests and rollback trigger.
  3. Verify that approved configuration was saved to startup, back up the previous state and test recovery before restarting a switch.
  4. Use supported Central scheduling, device groups, firmware compliance and post-upgrade validation instead of treating a portal job as proof of healthy operation.

Explanation

Correct Answer

D:

The decisive observed condition is: An automation schedule restarts every access switch simultaneously despite planned staged client availability. The appropriate switching action is: Use supported Central scheduling, device groups, firmware compliance and post-upgrade validation instead of treating a portal job as proof of healthy operation.

The observed case An automation schedule restarts every access switch simultaneously despite planned staged client availability requires the more specific central firmware and group compliance rollouts control. The targeted action is: Use supported Central scheduling, device groups, firmware compliance and post-upgrade validation instead of treating a portal job as proof of healthy operation.

Question 672

The switch operations team reports: An automation schedule restarts every access switch simultaneously despite planned staged client availability. What adverse switching behavior should the engineer anticipate?

  1. A queued or blocked Central operation can leave some switches on old software while dashboards imply the deployment finished.
  2. A technically correct change performed without coordination can interrupt critical services and prevent recovery within the approved outage allowance.
  3. An unsaved edit disappears on reboot while a mistakenly persisted temporary setting survives beyond its intended scope.
  4. Unrecorded VLAN or peer-role changes can turn routine incidents into extended outages and make compliance review unreliable.

Explanation

Correct Answer

A:

The direct operational failure mode is: A queued or blocked Central operation can leave some switches on old software while dashboards imply the deployment finished. It applies to the condition An automation schedule restarts every access switch simultaneously despite planned staged client availability. The suitable corrective action is: Use supported Central scheduling, device groups, firmware compliance and post-upgrade validation instead of treating a portal job as proof of healthy operation.

Question 673

An HPE Aruba Networking engineer observes: A branch LAG edit disconnects the only management path and no out-of-band route exists for recovery. 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. Maintain an approved OOB or alternate management access path and safe rollback instructions for switches whose in-band uplinks may fail.
  3. Verify that approved configuration was saved to startup, back up the previous state and test recovery before restarting a switch.
  4. Maintain switch inventory, topology, configuration standards, service owners and recovery checks after every approved network change.

Explanation

Correct Answer

B:

The decisive observed condition is: A branch LAG edit disconnects the only management path and no out-of-band route exists for recovery. The appropriate switching action is: Maintain an approved OOB or alternate management access path and safe rollback instructions for switches whose in-band uplinks may fail. It addresses the risk that a remote switch with only the affected in-band route can become unreachable precisely when rollback is needed. Confirm with: An isolated test site restores console or OOB management and rolls back a failed uplink change without physical improvisation.

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 observed case A branch LAG edit disconnects the only management path and no out-of-band route exists for recovery requires the more specific remote management emergency rollback and recovery access control. The targeted action is: Maintain an approved OOB or alternate management access path and safe rollback instructions for switches whose in-band uplinks may fail.

C:

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 targeted action is: Maintain an approved OOB or alternate management access path and safe rollback instructions for switches whose in-band uplinks may fail.

Question 674

An engineer investigates: A branch LAG edit disconnects the only management path and no out-of-band route exists for recovery. 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 comparison report identifies all unauthorized changes and confirms approved exceptions remain documented without false matches.
  3. A separate engineer follows the updated runbook to locate, inspect and safely restore an affected switch service.
  4. An isolated test site restores console or OOB management and rolls back a failed uplink change without physical improvisation.

Explanation

Correct Answer

D:

The independent acceptance evidence for A branch LAG edit disconnects the only management path and no out-of-band route exists for recovery is: An isolated test site restores console or OOB management and rolls back a failed uplink change without physical improvisation. It tests whether the team has actually implemented: Maintain an approved OOB or alternate management access path and safe rollback instructions for switches whose in-band uplinks may fail. An enabled interface or saved configuration by itself is not evidence of complete service recovery.
