Question 410

A network team changes device ownership during an acquisition without checking whether licensed WLAN features remain available under the receiving organization. How should the team correct this specific WLAN problem?

  1. Plan entitlement and device-claim reconciliation as part of the organization migration
  2. Scope the management role to intended sites and test inherited organization permissions
  3. Assign a role with the minimum required site and monitoring privileges
  4. Inspect the service entitlement and renewal status before diagnosing an unrelated wireless hardware failure

Explanation

Correct Answer

A:

Mist organization scope, least-privilege identities and active subscriptions must match the responsible tenant and deployed services. In the described case, plan entitlement and device-claim reconciliation as part of the organization migration resolves the identified control gap. Confirm with: The transferred AP has the approved organization owner and its required Wireless Assurance license works.

Incorrect Answers

B:

This is relevant to a separate account organization and subscriptions problem: A global WLAN uses site-specific administrators yet a template editor is inadvertently allowed to change every international location. It does not directly address this incident, which instead calls for: Plan entitlement and device-claim reconciliation as part of the organization migration.

C:

This is relevant to a separate account organization and subscriptions problem: A regional operations manager needs read-only SLE access but receives the full organization owner role. It does not directly address this incident, which instead calls for: Plan entitlement and device-claim reconciliation as part of the organization migration.

D:

This is relevant to a separate account organization and subscriptions problem: An AP fleet subscription expires during finals week, and the manager assumes the resulting analytics restrictions are a broken RF radio. It does not directly address this incident, which instead calls for: Plan entitlement and device-claim reconciliation as part of the organization migration.

Question 411

A branch uses wrong time synchronization and Mist event logs show a TLS onboarding certificate error. Which action should the specialist recommend FIRST?

  1. Validate AP uplink VLAN tagging and switch-path reachability as part of the acceptance checklist
  2. Survey actual access point locations and update mapping before enabling location-dependent features
  3. Check the device clock and approved NTP reachability alongside certificate validity
  4. Validate required client authentication and portal trust dependencies before enabling users

Explanation

Correct Answer

C:

Mist AP onboarding depends on local addressing, power, DNS, time, outbound management reachability and intended WLAN policy. In the described case, check the device clock and approved NTP reachability alongside certificate validity resolves the identified control gap. Confirm with: A corrected time source supports trusted cloud TLS and consistent incident timestamps.

Incorrect Answers

A:

This is relevant to a separate initial wireless setup and onboarding problem: An AP setup team assigns WLANs to a site before confirming the wired switch trunk carries the intended client VLANs.
