Question 680

A branch user reports repeated wireless disconnects while the central dashboard shows the AP online and healthy. If the revised setting disrupts users, which controlled rollback would be most relevant?

  1. Return the client-monitoring settings to the approved baseline while collecting bounded device logs for the incident.
  2. Withdraw the overprivileged token and restore the previous device configuration if the automation affects unrelated settings.
  3. Return to the previously working secure telemetry destination and route until the new collector path is repaired.
  4. Reinstate the last working mirror session and remove unsafe temporary mirroring if the destination becomes congested.

Explanation

Correct Answer

A:

Return the client-monitoring settings to the approved baseline while collecting bounded device logs for the incident. AP availability and end-user session continuity are different measures; per-client event correlation identifies the actual access phase. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described aruba central client health and event timeline situation. For the incident in this item: A branch user reports repeated wireless disconnects while the central dashboard shows the AP online and healthy.

Incorrect Answers

B:

Withdraw the overprivileged token and restore the previous device configuration if the automation affects unrelated settings. This instead concerns rest api and role-scoped automation. API management must honor resource method, authentication and response semantics; automation without scope and idempotent retry design risks unwanted changes. It would not safely roll back the relevant failed change. The immediate problem concerns aruba central client health and event timeline.

C:

Return to the previously working secure telemetry destination and route until the new collector path is repaired. This instead concerns snmp and syslog observability paths. Polling, traps and syslog are different observability flows; enabling one does not imply other event transports are correctly configured. It would not safely roll back the relevant failed change. The immediate problem concerns aruba central client health and event timeline. For the incident in this item: A branch user reports repeated wireless disconnects while the central dashboard shows the AP online and healthy.

D:

Reinstate the last working mirror session and remove unsafe temporary mirroring if the destination becomes congested. This instead concerns port mirroring and pcap capture. Mirroring copies selected traffic to an analyzer; selecting the wrong port or direction can create a misleading empty capture. It would not safely roll back the relevant failed change. The immediate problem concerns aruba central client health and event timeline.

Question 681

A network automation job can read AOS-CX status but gets authorization errors when attempting a supported configuration PATCH. Which investigation would best isolate the immediate network dependency?

  1. Inspect REST API response codes, token scope, requested resource URI and change idempotency.
  2. Inspect polling credentials, trap or syslog destination configuration, source VRF and transport reachability.
  3. Inspect the mirror session source, selected direction and destination interface capacity for the affected flow.
  4. Inspect the installed NAE script, monitored resource, condition and action history for the target metric.

Explanation

Correct Answer

A:

Inspect REST API response codes, token scope, requested resource URI and change idempotency. API management must honor resource method, authentication and response semantics; automation without scope and idempotent retry design risks unwanted changes. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described rest api and role-scoped automation situation.

Incorrect Answers

B:

Inspect polling credentials, trap or syslog destination configuration, source VRF and transport reachability. This instead concerns snmp and syslog observability paths. Polling, traps and syslog are different observability flows; enabling one does not imply other event transports are correctly configured. It does not isolate the cause of the stated incident. The immediate problem concerns rest api and role-scoped automation.

C:

Inspect the mirror session source, selected direction and destination interface capacity for the affected flow. This instead concerns port mirroring and pcap capture. Mirroring copies selected traffic to an analyzer; selecting the wrong port or direction can create a misleading empty capture. It does not isolate the cause of the stated incident. The immediate problem concerns rest api and role-scoped automation.

D:

Inspect the installed NAE script, monitored resource, condition and action history for the target metric. This instead concerns network analytics engine monitor rules. NAE scripts link monitors, rules, conditions and actions; the existence of a script does not prove its trigger or collection path works. It does not isolate the cause of the stated incident. The immediate problem concerns rest api and role-scoped automation.

Question 682

A network automation job can read AOS-CX status but gets authorization errors when attempting a supported configuration PATCH. Which specific corrective design step best meets the stated campus requirement?

  1. Restore secure SNMPv3 or syslog delivery to the authorized collector with correct routing and bounded permissions.
  2. Configure a supported port-mirroring session targeting the right source and capture interface without loops or oversubscription.
  3. Deploy a supported NAE monitor and rule with the right threshold and bounded diagnostic action for that AOS-CX model.
  4. Use the supported API method with minimum necessary permission and safe request or retry semantics.

Explanation

Correct Answer

D:

Use the supported API method with minimum necessary permission and safe request or retry semantics. API management must honor resource method, authentication and response semantics; automation without scope and idempotent retry design risks unwanted changes. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described rest api and role-scoped automation situation.

Incorrect Answers

A:

Restore secure SNMPv3 or syslog delivery to the authorized collector with correct routing and bounded permissions. This instead concerns snmp and syslog observability paths. Polling, traps and syslog are different observability flows; enabling one does not imply other event transports are correctly configured. It would not implement the specifically required change. The immediate problem concerns rest api and role-scoped automation.

B:

Configure a supported port-mirroring session targeting the right source and capture interface without loops or oversubscription. This instead concerns port mirroring and pcap capture. Mirroring copies selected traffic to an analyzer; selecting the wrong port or direction can create a misleading empty capture. It would not implement the specifically required change.

The immediate problem concerns rest api and role-scoped automation.

Question 683

A network automation job can read AOS-CX status but gets authorization errors when attempting a supported configuration PATCH. Following a targeted change, which acceptance test would most directly demonstrate success?

  1. Verify a controlled test event appears at the collector while live interface metrics can still be queried.
  2. Verify the capture shows expected packet directions and timestamps from a known test client.
  3. Verify a test request applies only the authorized change and produces the expected response and device state.
  4. Verify a controlled test condition produces the expected agent observation and alert evidence.

Explanation

Correct Answer

C:

Verify a test request applies only the authorized change and produces the expected response and device state. API management must honor resource method, authentication and response semantics; automation without scope and idempotent retry design risks unwanted changes. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described rest api and role-scoped automation situation.

Incorrect Answers

A:

Verify a controlled test event appears at the collector while live interface metrics can still be queried. This instead concerns snmp and syslog observability paths. Polling, traps and syslog are different observability flows; enabling one does not imply other event transports are correctly configured. It would not establish that this function actually works. The immediate problem concerns rest api and role-scoped automation.

B:

Verify the capture shows expected packet directions and timestamps from a known test client. This instead concerns port mirroring and pcap capture. Mirroring copies selected traffic to an analyzer; selecting the wrong port or direction can create a misleading empty capture. It would not establish that this function actually works. The immediate problem concerns rest api and role-scoped automation.

The immediate problem concerns rest api and role-scoped automation.

Question 684

A network automation job can read AOS-CX status but gets authorization errors when attempting a supported configuration PATCH. The change fails acceptance. What is the safest targeted restoration action?

  1. Return to the previously working secure telemetry destination and route until the new collector path is repaired.
  2. Revoke the overprivileged token and restore the previous device configuration if the automation affects unrelated settings.
  3. Restore the last working mirror session and remove unsafe temporary mirroring if the destination becomes congested.
  4. Revert the faulty NAE agent and restore a known-good monitor while tuning its trigger safely.

Explanation

Correct Answer

B:

Revoke the overprivileged token and restore the previous device configuration if the automation affects unrelated settings. API management must honor resource method, authentication and response semantics; automation without scope and idempotent retry design risks unwanted changes. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described rest api and role-scoped automation situation.

Question 685

A campus operations script accidentally runs repeated configuration updates because its API retry logic treats a successful response as a failure. Before implementing a remedy, what should the engineer check first?

  1. Review REST API response codes, token scope, requested resource URI and change idempotency.
  2. Review polling credentials, trap or syslog destination configuration, source VRF and transport reachability.
  3. Review the mirror session source, selected direction and destination interface capacity for the affected flow.

Question 686

A campus operations script accidentally runs repeated configuration updates because its API retry logic treats a successful response as a failure. After the root cause is confirmed, which narrowly scoped configuration action should be selected?

  1. Reinstate secure SNMPv3 or syslog delivery to the authorized collector with correct routing and bounded permissions.
  2. Set up a supported port-mirroring session targeting the right source and capture interface without loops or oversubscription.
  3. Roll out a supported NAE monitor and rule with the right threshold and bounded diagnostic action for that AOS-CX model.
  4. Choose the supported API method with minimum necessary permission and safe request or retry semantics.
