   A mining company operates in a remote area with limited power and no reliable internet. They plan to deploy EdgeX Foundry on a ruggedized gateway to collect vibration data from equipment. The gateway has 1 GB RAM and a dual-core CPU. The team must ensure the system can run continuously with minimal maintenance. Which deployment consideration is most critical for this environment?

   • AEnsure the gateway has a high-speed internet connection for real-time cloud backup
   • BOptimize the number of EdgeX services to fit within the memory and CPU limits
   • CDeploy all EdgeX services to ensure complete functionality
   • DUse a full desktop operating system to support all EdgeX features

   A smart parking system uses EdgeX Foundry to collect occupancy data from ultrasonic sensors. The data must be processed locally to detect free spots and then sent to a mobile app backend. Which EdgeX components should be used to achieve this?

   • ADevice service for sensor ingestion, application service for storage, and core data for export
   • BApplication service for sensor ingestion, core data for storage, and device service for export
   • CCore data service for sensor ingestion, device service for storage, and application service for export
   • DDevice service for ultrasonic sensors, core data for storage, and an application service to process and export to the backend

   A field deployment runs EdgeX Foundry on a small industrial PC with 2 GB RAM and a single-core CPU. The system must ingest data from 200 sensors and forward it to a cloud dashboard. The team is concerned about memory usage and wants to minimize the number of running services. Which approach best addresses this constraint?

   • AUse a single monolithic EdgeX service that includes all layers to reduce overhead
   • BReplace EdgeX with a cloud-based IoT hub to offload processing
   • CDeploy all default EdgeX services to ensure full functionality and future scalability
   • DRun only the required EdgeX microservices (core data, metadata, command, and the necessary device service) and disable unused supporting services
