Microsoft Azure Developer Associate AZ-204 Practice Question

A container named Transactions already contains several years of data. A background .NET service must forward only new inserts and updates to Azure Service Bus. The solution must 1) ignore existing items, 2) resume from the last processed change after restarts, and 3) allow multiple service instances without duplicate processing. Which implementation meets the requirements?

  • Configure a 1-second TTL on the container and process deleted documents from the change feed.

  • Use the Azure Cosmos DB Change Feed Processor SDK, set ChangeFeedStartFrom.Now, and store leases in a dedicated lease container.

  • Create a change-feed iterator with ChangeFeedStartFrom.Beginning and keep continuation tokens in memory.

  • Enable full-fidelity change feed mode and poll the container every minute for the latest _lsn values.
