CompTIA CASP+ (CAS-004) — Question 247

A company hosts a large amount of data in blob storage for its customers. The company recently had a number of issues with this data being prematurely deleted before the scheduled backup processes could be completed. The management team has asked the security architect for a recommendation that allows blobs to be deleted occasionally, but only after a successful backup. Which of the following solutions will BEST meet this requirement?

Answer options

• A. Mirror the blobs at a local data center.
• B. Enable fast recovery on the storage account.
• C. Implement soft delete for blobs.
• D. Make the blob immutable.

Correct answer: C

Explanation

The correct answer is C, as implementing soft delete for blobs allows blobs to be recoverable even after deletion, ensuring that they can be restored if a backup was completed. Option A does not prevent premature deletions, while option B focuses on recovery speed rather than deletion control. Option D makes blobs immutable, which does not allow for any deletions at all, contradicting the requirement for occasional deletions.
