   An edge deployment uses EdgeX Foundry to ingest data from IP cameras via RTSP. The operations team wants to ensure that only processed and filtered data is sent to the corporate data lake, while raw video frames remain at the edge. Which sequence of EdgeX components should be used to achieve this?

   • ADevice service → Core data → Application service with filter → Export to data lake
   • BDevice service → Application service → Core data → Export to data lake
   • CCore data → Device service → Application service → Export to data lake
   • DApplication service → Core data → Device service → Export to data lake

   A retail chain wants to process in-store footfall data locally to provide real-time alerts without relying on a stable internet connection. They are evaluating EdgeX Foundry as a potential solution. Which primary benefit of EdgeX Foundry makes it suitable for this scenario?

   • AIt provides a built-in data lake for long-term storage of all sensor data
   • BIt replaces the need for any local hardware by processing data entirely in the cloud
   • CIt runs at the edge, enabling local data processing and analytics even when connectivity to the cloud is intermittent
   • DIt automatically synchronizes all data to the cloud in real time

   A smart-building solution uses EdgeX Foundry to manage sensors from multiple vendors. The team wants to add a new type of BACnet thermostat without disrupting the existing running services. Which characteristic of EdgeX Foundry's microservices model makes this possible?

   • AEach device service runs as an independent microservice that can be added or updated without affecting other services
   • BThe application services layer must be restarted to register a new device service
   • CAll device services are compiled into a single binary that must be rebuilt to add new protocols
   • DThe core services automatically discover and load new device drivers from a shared library at runtime
