   A water treatment plant uses EdgeX Foundry to monitor chemical levels. The plant has a strict requirement that if the EdgeX system fails, the pumps must continue operating safely. The team is considering the microservices architecture. Which aspect of EdgeX's microservices model is most relevant to this requirement?

   • AIndividual services can be restarted or replaced without stopping the entire system, but safety-critical actuation should not depend solely on EdgeX
   • BThe microservices model guarantees zero downtime for all services
   • CThe core data service automatically takes over all device control if other services fail
   • DAll services run in a single process, making failure recovery simple

   What is the primary purpose of EdgeX Foundry in an edge computing environment?

   • ATo replace the need for any cloud services by storing all IoT data indefinitely on edge devices.
   • BTo act as a device driver that directly controls sensors and actuators without any abstraction layer.
   • CTo provide a vendor-neutral, open-source middleware platform that collects data from IoT devices and distributes it to applications and cloud systems.
   • DTo provide a proprietary hardware platform for deploying IoT devices at the edge.
