Microsoft Azure Developer Associate AZ-204 Practice Question

You are developing a console application that runs each night to move unprocessed blobs in the "images" container from the hot tier to the archive tier. Every blob is assigned the index tag processed="false" until it is handled. The solution must retrieve only the blobs that are still unprocessed and avoid enumerating the entire container client-side. Which approach should you use?

  • List blobs with BlobTraits.Metadata and filter the results where the metadata key processed equals "false".

  • Organize blobs under a virtual directory named "unprocessed/" and enumerate blobs with that prefix.

  • Use BlobChangeFeedClient.GetChanges to obtain blobs that have not yet been processed.

  • Call BlobContainerClient.FindBlobsByTagsAsync with the query "processed = 'false'".
