   A logistics company uses EdgeX Foundry to track containers with GPS devices that communicate via MQTT. They also have legacy RFID readers that use HTTP. The team wants to unify the data from both sources into a single stream for a central tracking application. How should they configure EdgeX Foundry?

   • AUse a single HTTP device service for both GPS and RFID
   • BUse an application service to ingest both MQTT and HTTP data directly
   • CDeploy an MQTT device service for GPS and an HTTP device service for RFID, both feeding into core data
   • DConvert all devices to use a proprietary protocol and use a custom device service

   A logistics company uses EdgeX Foundry to collect GPS data from trackers that publish messages over MQTT. They also need to integrate with a legacy system that uses REST APIs. Which EdgeX components should they use to support both MQTT and REST device connectivity?

   • AUse the application services layer to directly connect to both MQTT and REST devices
   • BUse a single generic device service that automatically detects the protocol
   • CUse an MQTT device service for the trackers and a REST device service for the legacy system
   • DConvert all devices to MQTT and use only an MQTT device service
