Question 730

An engineer says service analytics are not available for a locally bridged WLAN because no user packets are sent to the public cloud. What should the engineer investigate or configure next?

  1. Verify AP management-plane connectivity and WLAN client forwarding independently
  2. Design tenant-level organization isolation with explicit administrator and API identity boundaries
  3. Validate the supported AP telemetry path separately from client user-data forwarding
  4. Assess end-to-end WLAN service availability including wired uplinks, address servers and access identity systems

Explanation

Correct Answer

C:

Mist cloud control and observability are distinct from selected local or tunneled WLAN user-data forwarding paths. In the described case, validate the supported AP telemetry path separately from client user-data forwarding resolves the identified control gap. Confirm with: Mist monitoring receives permissible connection metrics while client traffic remains on the local network.

Incorrect Answers

A:

This is relevant to a separate cloud-managed wlan architecture and traffic paths problem: A site engineer equates AP cloud registration with proof that its physical uplink supports the intended client VLANs. It does not directly address this incident, which instead calls for: Validate the supported AP telemetry path separately from client user-data forwarding.

B:

This is relevant to a separate cloud-managed wlan architecture and traffic paths problem: A retail site uses a Mist organization for all regional customers despite contractual separation of configuration and user records. It does not directly address this incident, which instead calls for: Validate the supported AP telemetry path separately from client user-data forwarding.

D:

It does not directly address this incident, which instead calls for: Validate the supported AP telemetry path separately from client user-data forwarding.

Question 731

A warehouse 2.4 GHz scanner loses packets whenever a nearby microwave operates during lunch. Which response best follows from the observed evidence?

  1. Remove conflicting static channel constraints and verify the supported radio-management policy
  2. Distinguish spectrum selection from 6 GHz security prerequisites when diagnosing client admission
  3. Measure non-Wi-Fi interference in the affected band and adjust coverage or device placement
  4. Apply frequency-specific regulatory EIRP limits including antenna gain and installation conditions

Explanation

Correct Answer

C:

Channel planning depends on supported frequency bands, local regulatory rules, widths and actual interference. In the described case, measure non-Wi-Fi interference in the affected band and adjust coverage or device placement resolves the identified control gap. Confirm with: Time-aligned spectrum observations identify the interferer and scanner retries decline after mitigation.

Incorrect Answers

A:

This is relevant to a separate frequency bands and channel plans problem: A school plans automatic RF selection but locks every AP to the same static 5 GHz channel anyway. It does not directly address this incident, which instead calls for: Measure non-Wi-Fi interference in the affected band and adjust coverage or device placement.

B:

This is relevant to a separate frequency bands and channel plans problem: A dense apartment building changes 6 GHz channels but new clients continue failing due to unsupported WPA3 security settings.
