   A hospital is deploying IoT infusion pumps that must be remotely monitored and updated. The hospital's security team requires that all device communication be encrypted and that the pumps be isolated from the general IT network. The pumps are battery-powered and have limited processing capacity. Which approach best meets both security and operational requirements?

   • AUse the hospital's general Wi-Fi network and install antivirus software on each pump.
   • BConnect the pumps directly to the internet and rely on the cloud platform for security.
   • CPlace the pumps on a separate IoT network with a gateway that encrypts traffic and manages updates.
   • DDisable remote monitoring and updates to avoid security risks.

   A company is deploying IoT sensors in a factory to monitor equipment vibration. The sensors are battery-powered and located in areas with no Wi-Fi coverage. The company wants to minimize battery replacement costs while ensuring data is available for predictive maintenance. Which communication technology is most appropriate?

   • AWi-Fi, because it is already available in the factory.
   • BCellular 5G, because it provides high bandwidth and low latency.
   • CBluetooth Low Energy (BLE), because it has low power consumption.
   • DLow-Power Wide-Area Network (LPWAN), because it offers long range and low power consumption.

   A manufacturer is adding IoT sensors to its production line to predict equipment failures before they occur. The sensors generate a large volume of time-series data. The company wants to minimize the cost of transmitting and storing all raw data in the cloud. Which approach best addresses this challenge?

   • APerform edge analytics on the gateway to send only anomaly summaries to the cloud.
   • BSend all raw sensor data directly to the cloud for maximum fidelity.
   • CUse a higher-frequency sampling rate to capture more detailed data.
   • DStore all data locally on each sensor's memory and never transmit it.

   A farming cooperative is considering IoT soil-moisture sensors to optimize irrigation. The sensors would transmit data to a cloud platform that sends watering recommendations to farmers' smartphones. The cooperative's main goal is to reduce water usage, but it also wants to minimize the upfront investment in network infrastructure. Which deployment approach best meets both goals?

   • ADeploy a mesh network of sensors where each sensor relays data from others, eliminating the need for a gateway.
   • BConnect sensors directly to the cloud via satellite links, which are available everywhere.
   • CUse cellular IoT modules in each sensor, avoiding the need to build a private network.
   • DInstall Wi-Fi repeaters across the entire farm to ensure every sensor has strong connectivity.
