   A rural healthcare clinic is setting up a telemedicine system with wearable devices that monitor patients' vital signs. The clinic has unreliable power and internet connectivity. The devices must operate for at least 24 hours on battery and transmit data to a central server when connectivity is available. The clinic also needs to ensure that data is not lost during connectivity outages. Which network architecture and protocol combination is most appropriate?

   • AHybrid network with LoRaWAN and store-and-forward using MQTT
   • BMesh network with Bluetooth Low Energy and store-and-forward using MQTT
   • CStar network with Wi-Fi and store-and-forward using CoAP
   • DStar network with Zigbee and store-and-forward using HTTP

   A logistics company is deploying sensors to track containers in a port. The port has a dense network of Wi-Fi access points, but the containers are stacked in a way that blocks line-of-sight. The sensors must transmit location and temperature data every 5 minutes. The company wants to minimize power consumption and ensure that data can be routed around obstacles. Which wireless technology and topology should they use?

   • ABluetooth Low Energy mesh
   • BZigbee mesh network
   • CWi-Fi star topology
   • DLoRaWAN star-of-stars topology
