   A hospital is deploying Mist vBLE to track infusion pumps. The pumps move between floors, and the staff need to locate a specific pump within a few meters. The BLE tags have been onboarded and assigned to the pumps. However, the location shown in the Mist dashboard is consistently off by 10–15 meters, and the error is worse on the second floor, which has a large open atrium. Which action should the administrator take FIRST to improve accuracy?

   • ARun the calibration routine in the Mist portal to collect radio frequency (RF) fingerprints for the environment, especially the atrium area.
   • BDisable the Mist cloud's location engine and use the raw RSSI values from the nearest AP for manual triangulation.
   • CReplace the BLE tags with a different vendor's tags that transmit at a higher power level.
   • DIncrease the BLE advertisement interval on all tags to the maximum supported value.

   A manufacturing plant wants to use Mist vBLE to track the location of safety equipment, such as fire extinguishers and first-aid kits, across a large facility. The administrator has installed the APs and onboarded the tags. What is the primary benefit of using Mist vBLE for this use case compared to a manual inventory check?

   • AIt guarantees the equipment will never be moved without authorization.
   • BIt provides real-time visibility of the equipment's location without requiring a physical search.
   • CIt allows the equipment to be tracked even when it is outside the facility's coverage area.
   • DIt eliminates the need for any ongoing maintenance of the tracking system.
