   A building management company operates IoT sensors for HVAC control in multiple office buildings. The sensors are reaching end-of-life, and the company needs to replace them without disrupting building operations. What is the best lifecycle management approach?

   • APhase the replacement by zone, testing new sensors before decommissioning old ones.
   • BContinue using the old sensors until they fail completely.
   • CReplace all sensors at once during a weekend shutdown.
   • DUpgrade the firmware of the old sensors to extend their life indefinitely.

   A transportation authority operates IoT sensors on bridges to monitor structural health. The sensors are connected via a private LTE network. The operations team needs to ensure that firmware updates do not disrupt data collection during peak traffic hours. What is the most appropriate update strategy?

   • AUpdate all sensors simultaneously during peak traffic hours to get it done quickly.
   • BDo not update the sensors unless a critical vulnerability is found.
   • CSchedule updates during low-traffic periods and use a rolling update that updates a subset of sensors at a time.
   • DUpdate the sensors manually one by one over several weeks.

   A retail chain deploys IoT temperature sensors in refrigerators at 50 stores. The sensors connect to a central cloud platform via the store's internet connection. During deployment, the team must ensure that sensor data is not exposed to other devices on the store network. What should they configure?

   • AAssign the sensors public IP addresses so they can communicate directly with the cloud.
   • BDisable the store's firewall to ensure the sensors can reach the cloud.
   • CUse the same SSID as the store's guest Wi-Fi for simplicity.
   • DPlace the sensors on a separate VLAN or isolated network segment dedicated to IoT devices.
