Question 670

An office's digital experience sensor tests internet reachability but fails to detect that an internal business application is inaccessible. After the root cause is confirmed, which narrowly scoped configuration action should be selected?

  1. Activate the appropriate supported client insight and alerting scope for the target site without expanding unrelated log collection.
  2. Set up approved UXI synthetic tests for the affected wireless or wired access journey and application target.
  3. Choose the supported API method with minimum necessary permission and safe request or retry semantics.
  4. Reinstate secure SNMPv3 or syslog delivery to the authorized collector with correct routing and bounded permissions.

Explanation

Correct Answer

B:

Set up approved UXI synthetic tests for the affected wireless or wired access journey and application target. UXI observations depend on the sensor location and explicit test journey; a successful generic ping does not validate application experience. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described uxi sensor internal and external testing situation.

Incorrect Answers

A:

Activate the appropriate supported client insight and alerting scope for the target site without expanding unrelated log collection. This instead concerns aruba central client health and event timeline. AP availability and end-user session continuity are different measures; per-client event correlation identifies the actual access phase. It would not implement the specifically required change. The immediate problem concerns uxi sensor internal and external testing.

C:

Choose the supported API method with minimum necessary permission and safe request or retry semantics. 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 implement the specifically required change. The immediate problem concerns uxi sensor internal and external testing.

D:

Reinstate 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 uxi sensor internal and external testing.

Question 671

An office's digital experience sensor tests internet reachability but fails to detect that an internal business application is inaccessible. A deployment job reports success. Which observed result would actually validate the affected service?

  1. Confirm scheduled synthetic results distinguish successful authentication from failed internal or external service tests.
  2. Verify a reproduction produces a timestamped client event chain that identifies the failure stage.
  3. Confirm a test request applies only the authorized change and produces the expected response and device state.
  4. Confirm a controlled test event appears at the collector while live interface metrics can still be queried.

Explanation

Correct Answer

A:

Confirm scheduled synthetic results distinguish successful authentication from failed internal or external service tests. UXI observations depend on the sensor location and explicit test journey; a successful generic ping does not validate application experience. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described uxi sensor internal and external testing situation.

Incorrect Answers

B:

Verify a reproduction produces a timestamped client event chain that identifies the failure stage. This instead concerns aruba central client health and event timeline. AP availability and end-user session continuity are different measures; per-client event correlation identifies the actual access phase. It would not establish that this function actually works. The immediate problem concerns uxi sensor internal and external testing.

C:

Confirm a test request applies only the authorized change and produces the expected response and device state. 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 establish that this function actually works. The immediate problem concerns uxi sensor internal and external testing.

D:

Confirm 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 uxi sensor internal and external testing.

Question 672

An office's digital experience sensor tests internet reachability but fails to detect that an internal business application is inaccessible. 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 previous stable test plan and relocate or reprovision an unhealthy UXI sensor without mislabeling failures.

Explanation

Correct Answer

D:

Reinstate the previous stable test plan and relocate or reprovision an unhealthy UXI sensor without mislabeling failures. UXI observations depend on the sensor location and explicit test journey; a successful generic ping does not validate application experience. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described uxi sensor internal and external testing situation.

Incorrect Answers

A:

Return the client-monitoring settings to the approved baseline while collecting bounded device logs for the incident. This instead concerns aruba central client health and event timeline. AP availability and end-user session continuity are different measures; per-client event correlation identifies the actual access phase. It would not safely roll back the relevant failed change. The immediate problem concerns uxi sensor internal and external testing. For the incident in this item: An office's digital experience sensor tests internet reachability but fails to detect that an internal business application is inaccessible.

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 uxi sensor internal and external testing.

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 uxi sensor internal and external testing. For the incident in this item: An office's digital experience sensor tests internet reachability but fails to detect that an internal business application is inaccessible.

Question 673

A WLAN client drops every hour but the operator looks only at the aggregate AP uptime dashboard. 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 per-client association, authentication, roaming and disconnect events correlated to the user's timeline.

Explanation

Correct Answer

D:

Inspect per-client association, authentication, roaming and disconnect events correlated to the user's timeline. AP availability and end-user session continuity are different measures; per-client event correlation identifies the actual access phase. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described aruba central client health and event timeline situation.

Incorrect Answers

A:

Inspect REST API response codes, token scope, requested resource URI and change idempotency. 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 does not isolate the cause of the stated incident. The immediate problem concerns aruba central client health and event timeline.

The immediate problem concerns aruba central client health and event timeline.

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 aruba central client health and event timeline.

Question 674

A WLAN client drops every hour but the operator looks only at the aggregate AP uptime dashboard. Which specific corrective design step best meets the stated campus requirement?

  1. Use the supported API method with minimum necessary permission and safe request or retry semantics.
  2. Restore secure SNMPv3 or syslog delivery to the authorized collector with correct routing and bounded permissions.
  3. Enable the appropriate supported client insight and alerting scope for the target site without expanding unrelated log collection.
  4. Configure a supported port-mirroring session targeting the right source and capture interface without loops or oversubscription.

Explanation

Correct Answer

C:

Enable the appropriate supported client insight and alerting scope for the target site without expanding unrelated log collection. AP availability and end-user session continuity are different measures; per-client event correlation identifies the actual access phase.

Question 675

A WLAN client drops every hour but the operator looks only at the aggregate AP uptime dashboard. Following a targeted change, which acceptance test would most directly demonstrate success?

  1. Verify a test request applies only the authorized change and produces the expected response and device state.
  2. Confirm a reproduction produces a timestamped client event chain that identifies the failure stage.
  3. Verify a controlled test event appears at the collector while live interface metrics can still be queried.
  4. Verify the capture shows expected packet directions and timestamps from a known test client.

Question 676

A WLAN client drops every hour but the operator looks only at the aggregate AP uptime dashboard. The change fails acceptance. What is the safest targeted restoration action?

  1. Return the client-monitoring settings to the approved baseline while collecting bounded device logs for the incident.
  2. Revoke 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. Restore the last working mirror session and remove unsafe temporary mirroring if the destination becomes congested.
