Microsoft Azure Developer Associate AZ-204 Practice Question

You are developing a .NET 6 worker service that uploads log files to an Azure Blob Storage container by using the Azure.Storage.Blobs SDK (v12). Every uploaded blob must meet these requirements:

  • The Content-Type header must be set to "text/plain" so that browsers render the file correctly when it is downloaded.
  • A custom metadata key named "department" must store the originating department code so that you can later filter blobs by that value. You also want to minimize the number of write transactions that are billed. Which code approach should you use to meet all the requirements?

  • Call BlobClient.UploadAsync(stream, new BlobUploadOptions { HttpHeaders = new BlobHttpHeaders , Metadata = new Dictionary<string,string> { ["department"] = deptCode } });

  • Upload the blob with overwrite set to true, then call BlobClient.SetTagsAsync(new Dictionary<string,string> { ["department"] = deptCode, ["Content-Type"] = "text/plain" });

  • Upload the blob, then call BlobClient.SetHttpHeadersAsync(new BlobHttpHeaders ) followed by BlobClient.SetMetadataAsync(new Dictionary<string,string> { ["department"] = deptCode });

  • Open a writable stream by using BlobClient.OpenWrite(overwrite:true, new BlobOpenWriteOptions { HttpHeaders = new BlobHttpHeaders }) and write the content; metadata is added automatically.
