Zorluk: KolayPerform Blob and Container Operations using Azure Storage SDKs

You are developing a C# application that uses the Azure.Storage.Blobs SDK (v12) to manage files in Azure Blob Storage. You need to delete a blob that currently has an active, exclusive-write lease. Which two actions can you perform to successfully delete the blob? (Select two.)

  1. Call the DeleteAsync method on the BlobClient and pass the active lease ID in a BlobRequestConditions object.Cevap
  2. Instantiate a BlobLeaseClient for the blob, call BreakAsync to release the lease lock, and then call DeleteAsync on the BlobClient.Cevap
  3. C
    Call the DeleteAsync method on the BlobClient directly without specifying a lease ID, as leases only block write operations.
  4. D
    Instantiate a BlobLeaseClient for the blob, call AcquireAsync to acquire a new lease, and then call DeleteAsync on the BlobClient without specifying a lease ID.

Cevap

To delete a leased blob, you must either provide the active lease ID using a BlobRequestConditions object when calling DeleteAsync, or break the active lease using a BlobLeaseClient before calling DeleteAsync.
To delete a blob that has an active lease, you can either provide the lease ID in the request conditions using a BlobRequestConditions object, or release/break the lease lock on the blob using a BlobLeaseClient prior to deletion. Both methods satisfy the requirements for modifying or deleting a leased resource in Azure Storage.

Adım Adım Çözüm

1
Determine if the lease needs to be kept active during the operation or if it can be terminated.
If the lease can be terminated, it can be broken. If it must remain active, the delete request must include the lease ID.
This determines which API call sequence to use.
2
Implement the deletion using request conditions with the lease ID, or break the lease first.
Passing the lease ID in BlobRequestConditions allows the delete to proceed, while breaking the lease removes the lock so that a standard delete call works.
Both methods are valid ways to bypass the write/delete lock imposed by the lease.
