Question 650

A security analyst cannot determine whether a campus switch forwards DHCP offers because a span capture on the wrong interface is empty. Which specific corrective design step best meets the stated campus requirement?

  1. Deploy a supported NAE monitor and rule with the right threshold and bounded diagnostic action for that AOS-CX model.
  2. Configure approved UXI synthetic tests for the affected wireless or wired access journey and application target.
  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

D:

Configure a supported port-mirroring session targeting the right source and capture interface without loops or oversubscription. Mirroring copies selected traffic to an analyzer; selecting the wrong port or direction can create a misleading empty capture. The proposed configuration targets the stated dependency without broadening unrelated access. The decision applies to the described port mirroring and pcap capture situation.

Incorrect Answers

A:

Deploy a supported NAE monitor and rule with the right threshold and bounded diagnostic action for that AOS-CX model. 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 would not implement the specifically required change. The immediate problem concerns port mirroring and pcap capture.

B:

Configure approved UXI synthetic tests for the affected wireless or wired access journey and application target. This instead concerns uxi sensor internal and external testing. UXI observations depend on the sensor location and explicit test journey; a successful generic ping does not validate application experience. It would not implement the specifically required change. The immediate problem concerns port mirroring and pcap capture.

C:

Enable 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 port mirroring and pcap capture.

Question 651

A security analyst cannot determine whether a campus switch forwards DHCP offers because a span capture on the wrong interface is empty. Following a targeted change, which acceptance test would most directly demonstrate success?

  1. Verify a controlled test condition produces the expected agent observation and alert evidence.
  2. Verify scheduled synthetic results distinguish successful authentication from failed internal or external service tests.
  3. Verify the capture shows expected packet directions and timestamps from a known test client.
  4. Confirm a reproduction produces a timestamped client event chain that identifies the failure stage.

Explanation

Correct Answer

C:

Verify the capture shows expected packet directions and timestamps from a known test client. Mirroring copies selected traffic to an analyzer; selecting the wrong port or direction can create a misleading empty capture. The result tests actual working behavior, not merely a saved configuration. The decision applies to the described port mirroring and pcap capture situation.

Incorrect Answers

A:

Verify a controlled test condition produces the expected agent observation and alert evidence. 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 would not establish that this function actually works. The immediate problem concerns port mirroring and pcap capture.

B:

Verify scheduled synthetic results distinguish successful authentication from failed internal or external service tests. This instead concerns uxi sensor internal and external testing. UXI observations depend on the sensor location and explicit test journey; a successful generic ping does not validate application experience. It would not establish that this function actually works. The immediate problem concerns port mirroring and pcap capture.

D:

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 port mirroring and pcap capture.

Question 652

A security analyst cannot determine whether a campus switch forwards DHCP offers because a span capture on the wrong interface is empty. The change fails acceptance. What is the safest targeted restoration action?

  1. Revert the faulty NAE agent and restore a known-good monitor while tuning its trigger safely.
  2. Restore the last working mirror session and remove unsafe temporary mirroring if the destination becomes congested.
  3. Restore the previous stable test plan and relocate or reprovision an unhealthy UXI sensor without mislabeling failures.
  4. Return the client-monitoring settings to the approved baseline while collecting bounded device logs for the incident.

Explanation

Correct Answer

B:

Restore the last working mirror session and remove unsafe temporary mirroring if the destination becomes congested. Mirroring copies selected traffic to an analyzer; selecting the wrong port or direction can create a misleading empty capture. The focused rollback restores a known safe baseline before another change attempt. The decision applies to the described port mirroring and pcap capture situation.

Incorrect Answers

A:

Revert the faulty NAE agent and restore a known-good monitor while tuning its trigger safely. 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 would not safely roll back the relevant failed change. The immediate problem concerns port mirroring and pcap capture.

C:

Restore the previous stable test plan and relocate or reprovision an unhealthy UXI sensor without mislabeling failures. This instead concerns uxi sensor internal and external testing. UXI observations depend on the sensor location and explicit test journey; a successful generic ping does not validate application experience. It would not safely roll back the relevant failed change. The immediate problem concerns port mirroring and pcap capture.

D:

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 port mirroring and pcap capture.

Question 653

A NOC engineer uses a packet analyzer attached to a mirror port but sees only ingress traffic from an AP uplink. Before implementing a remedy, what should the engineer check first?

  1. Review the mirror session source, selected direction and destination interface capacity for the affected flow.
  2. Review the installed NAE script, monitored resource, condition and action history for the target metric.
  3. Review UXI sensor connectivity and the configured internal, external and authentication test definitions.
  4. Review per-client association, authentication, roaming and disconnect events correlated to the user's timeline.

Explanation

Correct Answer

A:

Review the mirror session source, selected direction and destination interface capacity for the affected flow. Mirroring copies selected traffic to an analyzer; selecting the wrong port or direction can create a misleading empty capture. The evidence check isolates the relevant prerequisite before a disruptive change. The decision applies to the described port mirroring and pcap capture situation.

Incorrect Answers

B:

Review the installed NAE script, monitored resource, condition and action history for the target metric. This instead concerns network analytics engine monitor rules.

The immediate problem concerns port mirroring and pcap capture.

Question 654

A NOC engineer uses a packet analyzer attached to a mirror port but sees only ingress traffic from an AP uplink. After the root cause is confirmed, which narrowly scoped configuration action should be selected?

  1. Roll out a supported NAE monitor and rule with the right threshold and bounded diagnostic action for that AOS-CX model.
  2. Set up approved UXI synthetic tests for the affected wireless or wired access journey and application target.
  3. Activate the appropriate supported client insight and alerting scope for the target site without expanding unrelated log collection.
  4. Set up a supported port-mirroring session targeting the right source and capture interface without loops or oversubscription.

Question 655

A NOC engineer uses a packet analyzer attached to a mirror port but sees only ingress traffic from an AP uplink. A deployment job reports success. Which observed result would actually validate the affected service?

  1. Confirm a controlled test condition produces the expected agent observation and alert evidence.
  2. Confirm scheduled synthetic results distinguish successful authentication from failed internal or external service tests.
  3. Confirm the capture shows expected packet directions and timestamps from a known test client.
  4. Verify a reproduction produces a timestamped client event chain that identifies the failure stage.

Question 656

A NOC engineer uses a packet analyzer attached to a mirror port but sees only ingress traffic from an AP uplink. If the revised setting disrupts users, which controlled rollback would be most relevant?

  1. Undo the faulty NAE agent and restore a known-good monitor while tuning its trigger safely.
  2. Reinstate the last working mirror session and remove unsafe temporary mirroring if the destination becomes congested.
  3. Reinstate the previous stable test plan and relocate or reprovision an unhealthy UXI sensor without mislabeling failures.
  4. Return the client-monitoring settings to the approved baseline while collecting bounded device logs for the incident.
