Question 1110

At Research Hub, a campus gateway never receives employee SSID packets because the WLAN is set to bridge locally. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Preserve management-plane isolation and avoid moving monitoring to an unrestricted production VRF.
  2. Choose approved bridge or tunneled forwarding mode and correctly map AP VLAN or gateway cluster.
  3. Demonstrate subscription device identity Central assignment and management reachability in the authorized tenant.
  4. Assess roaming and segmentation impacts before changing WLAN forwarding mode.

Explanation

Correct Answers

B:

This is the implementation element for the Research Hub case: Bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy. The specific action Choose approved bridge or tunneled forwarding mode and correctly map AP VLAN or gateway cluster addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Research Hub. Assess roaming and segmentation impacts before changing WLAN forwarding mode prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

A:

This may be an ongoing precaution for Management VRF reachability: AOS-CX management VRF and default forwarding VRF may have separate reachability. It does not resolve the Bridge versus tunneled WLAN traffic requirement in Research Hub and is not one of the two controls requested. The direct mechanism here is bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy

C:

This may be a configuration step for Central device onboarding: Cloud inventory association and device management connectivity are separate onboarding requirements. It does not resolve the Bridge versus tunneled WLAN traffic requirement in Research Hub and is not one of the two controls requested. The direct mechanism here is bridge SSIDs forward locally; tunneled SSIDs use the gateway data path for policy

Question 1111

At Learning Commons, an access controller sends requests from an address omitted from ClearPass NAD definitions. What should the engineer implement first to correct the stated condition?

  1. Bind the device to its approved group and review group-level settings and local overrides.
  2. Define reachable RADIUS servers shared secrets and correct NAS source addresses.
  3. Demonstrate subscription device identity Central assignment and management reachability in the authorized tenant.
  4. Add an authorized management-VRF route and correct source reachability for the target service.

Explanation

Correct Answer

B:

For Learning Commons, the decisive mechanism is RADIUS server connectivity. NAD identity and transport reachability must be correct before policy results matter. Define reachable RADIUS servers shared secrets and correct NAS source addresses establishes the needed configuration in the case rather than merely measuring a symptom.

Incorrect Answers

A:

This is relevant to Central group assignment, where central groups govern configuration inheritance while sites mainly aid location and operations In the Learning Commons case, Changing that neighboring feature does not implement the missing function. The specific mechanism is nAD identity and transport reachability must be correct before policy results matter

C:

This is relevant to Central device onboarding, where cloud inventory association and device management connectivity are separate onboarding requirements In the Learning Commons case, Changing that neighboring feature does not implement the missing function.

D:

This is relevant to Management VRF reachability, where aOS-CX management VRF and default forwarding VRF may have separate reachability In the Learning Commons case, Changing that neighboring feature does not implement the missing function. The specific mechanism is nAD identity and transport reachability must be correct before policy results matter

Question 1112

At East Student Center, a new SSID prompts users to trust an unknown RADIUS server certificate because the chain changed. What measured or witnessed result should be required before signoff?

  1. Check approved administrators connect while ordinary user subnets cannot.
  2. Check clients securely verify the intended RADIUS server before joining.
  3. Correlate a test session and termination with the intended accounting records.
  4. Test allowed application connectivity and rejected unauthorized east-west traffic.

Explanation

Correct Answer

B:

For East Student Center, the decisive mechanism is EAP-TLS RADIUS server certificate. Mutual TLS requires client-side confidence in the EAP server identity. Confirm clients securely verify the intended RADIUS server before joining supplies measurable, case-relevant evidence that the intended behavior actually occurs.

Incorrect Answers

A:

This is relevant to Management plane protection, where data-plane forwarding policy does not automatically secure device management services In the East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mutual TLS requires client-side confidence in the EAP server identity

C:

This is relevant to RADIUS accounting traceability, where authentication and accounting provide different information and require separate configuration In the East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mutual TLS requires client-side confidence in the EAP server identity

D:

This is relevant to Campus microsegmentation, where role-based segmentation can limit lateral flows beyond simple VLAN separation In the East Student Center case, That test could pass while the actual user-facing requirement still fails. The specific mechanism is mutual TLS requires client-side confidence in the EAP server identity

Question 1113

At Lakeside Classroom, a switch CPU spikes during peak hours but Central shows only current readings. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.

  1. Install a supported Network Analytics Engine script/agent with relevant resource monitors and alerts.
  2. Treat cumulative counters as rates over time rather than interpreting raw lifetime totals.
  3. Configure complementary UXI internal service and external Internet tests.
  4. Use tested scripts with supported permissions and avoid uncontrolled remediation actions.

Explanation

Correct Answers

A:

This is the implementation element for the Lakeside Classroom case: NAE agents monitor local switch state and can correlate rule conditions over time. The specific action Install a supported Network Analytics Engine script/agent with relevant resource monitors and alerts addresses the stated fault; the question also requires a persistent risk control.

D:

This is the continuing risk-control element for Lakeside Classroom. Use tested scripts with supported permissions and avoid uncontrolled remediation actions prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.

Incorrect Answers

B:

This may be an ongoing precaution for Switch telemetry counters: Interface counters help distinguish physical corruption from congestion drops. It does not resolve the NAE monitor rule requirement in Lakeside Classroom and is not one of the two controls requested. The direct mechanism here is nAE agents monitor local switch state and can correlate rule conditions over time

C:

This may be a configuration step for UXI internal and external tests: Internal and external synthetic tests isolate distinct service paths and failure domains. It does not resolve the NAE monitor rule requirement in Lakeside Classroom and is not one of the two controls requested. The direct mechanism here is nAE agents monitor local switch state and can correlate rule conditions over time
