Question 290

An engineer deletes a network profile in use by several production access points, causing unexpected service loss. Which configuration or control should the operator select?

  1. Bind the WLAN configuration to the correct deployment scope and verify effective AP settings
  2. Inspect the supported configuration precedence and the resulting device configuration
  3. Inventory active object references before retiring the shared configuration item
  4. Preserve or explicitly reconcile dependent WLAN and policy objects during template migration

Explanation

Correct Answer

C:

Reusable Mist configuration objects require correct references, inheritance, target membership and verified device delivery. In the described case, inventory active object references before retiring the shared configuration item resolves the identified control gap. Confirm with: All dependent APs have migrated to a supported replacement before the object is removed.

Incorrect Answers
