   A company synchronizes product data from an external ERP into Dataverse. The ERP sends a 'ProductCode' that is unique, but sometimes the same ProductCode appears in multiple records due to a data quality issue. The developer has defined an alternate key on ProductCode. What is the expected behavior when the developer uses UpsertRequest with a ProductCode that matches multiple existing records?

   • AThe UpsertRequest will update the first record it finds with that ProductCode.
   • BThe UpsertRequest will update all records that match the ProductCode.
   • CThe UpsertRequest will create a new record because the alternate key is not recognized.
   • DThe UpsertRequest will fail with an error because the alternate key is not unique.

   A developer is using the Dataverse Web API to synchronize changes for the 'lead' entity. The first request returns a deltaLink. After processing the changes, the developer saves the deltaLink. On the next run, the developer uses the saved deltaLink and receives a 410 Gone error. What is the most likely cause?

   • AThe deltaLink has expired because the retention period for change tracking has passed.
   • BThe deltaLink was saved incorrectly because it contains a URL-encoded character.
   • CThe entity has been disabled for change tracking.
   • DThe developer used the wrong HTTP method for the request.
