   A company uses a nightly integration to synchronize its external CRM with Dataverse. The integration currently queries all records in the Contact table each night and compares timestamps to detect changes. The company wants to reduce the amount of data transferred and the processing time. You need to configure Dataverse to support an incremental synchronization approach. What should you do?

   • AAdd a new DateTime column to the Contact table and index it to speed up the timestamp comparison query.
   • BSchedule the integration to run more frequently so that fewer records change between runs.
   • CCreate an alternate key on the Contact table and use the UpsertRequest message in the integration.
   • DEnable change tracking for the Contact table and modify the integration to use the RetrieveEntityChanges message.

   A developer is using change tracking to sync Dataverse 'opportunity' records to an external system. The developer notices that the change tracking response includes records that were not actually changed, but were updated by a system job that touches the record's 'ModifiedOn' field. What is the best way to handle this?

   • AUse the 'ModifiedOn' field as the alternate key to identify only meaningful changes.
   • BDisable change tracking and use a custom audit log to track actual changes.
   • CFilter the changes by comparing the 'ModifiedOn' value to the last sync time and ignore records with no meaningful changes.
   • DAccept the extra records and process them idempotently, since the external system can handle duplicates.
