HOTSPOT (Drag and Drop is not supported)
You are developing a web application by using the Azure SDK. The web application accesses data in a zone-redundant BlockBlobStorage storage account.
The application must determine whether the data has changed since the application last read the data. Update operations must use the latest data changes when writing data to the storage account.
You need to implement the update operations.
Which values should you use? To answer, select the appropriate option in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:


Box 1: Last Modified
The Last-Modified response HTTP header contains a date and time when the origin server believes the resource was last modified. It is used as a validator to determine if the resource is the same as the previously stored one. Less accurate than an ETag header, it is a fallback mechanism.
Box 2: If-Modified-Since
Conditional Header If-Modified-Since:
A DateTime value. Specify this header to perform the operation only if the resource has been modified since the specified time.
Incorrect:
Not ETag/If-Match
Conditional Header If-Match:
An ETag value. Specify this header to perform the operation only if the resource's ETag matches the value specified. For versions 2011-08-18 and newer, the
ETag can be specified in quotes.

An organization deploys a blob storage account. Users take multiple snapshots of the blob storage account over time.
You need to delete all snapshots of the blob storage account. You must not delete the blob storage account itself.
How should you complete the code segment? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:


Box 1: DeleteSnapshotsOption
Sample code in powershell:
//dont forget to add the include snapshots :)
await batchClient.DeleteBlobsAsync(listofURIforBlobs,
Azure.Storage.Blobs.Models.DeleteSnapshotsOption.IncludeSnapshots);
Sample code in .Net:
// Create a batch with three deletes
BlobBatchClient batchClient = service.GetBlobBatchClient();
BlobBatch batch = batchClient.CreateBatch();
batch.DeleteBlob(foo.Uri, DeleteSnapshotsOption.IncludeSnapshots); batch.DeleteBlob(bar.Uri, DeleteSnapshotsOption.OnlySnapshots); batch.DeleteBlob(baz.Uri);
// Submit the batch
batchClient.SubmitBatch(batch);
Box 2: OnlySnapshots
