AZ-305 Question 124
Select 2Fabrikam stores thousands of transaction log files in Azure Blob Storage. The data must be retained for up to 7 years to meet compliance requirements, but it is rarely accessed. The company is concerned about accidental deletion or tampering and wants a cost-effective solution that can quickly restore data or recover older versions if needed. Which two capabilities should you recommend to meet these requirements?
- A
Enable Azure Storage soft delete to allow recovery of recently deleted data.
- B
Enable versioning for Azure Blobs to maintain older versions and revert changes.
- C
Configure Azure Site Recovery to replicate your blob data to a secondary region.
- D
Use geo-redundant storage (GRS) for automatic replication of data across regions.
Show answer and explanation
Correct answers: A, B
Explanation
For unstructured data in Azure Blob Storage, soft delete and blob versioning offer a targeted, cost-effective method to recover from accidental deletions and data corruption. Soft delete provides the ability to restore recently deleted blobs, while versioning maintains past object states. Together, these features address compliance retention, accidental deletion, and tampering concerns. Refer to Microsoft’s documentation for more details: https://learn.microsoft.com/azure/storage/blobs/versioning-overview and https://learn.microsoft.com/azure/storage/blobs/soft-delete-overview.
- A. Correct.
Option 1: Correct. Enabling soft delete for Azure Blob Storage or the entire storage account lets you recover data that has been accidentally or maliciously deleted within the retention window you configure.
- B. Correct.
Option 2: Correct. Blob versioning maintains historical versions of your blobs. If data is overwritten or corrupted, you can roll back to a previous version, which meets the requirement for quick restore in case of tampering or accidental changes.
- C. Incorrect.
Option 3: Incorrect. Azure Site Recovery is primarily designed for disaster recovery of virtual machines or entire applications, not for granular backup and restore of unstructured data in Blob Storage. It doesn’t address versioning or deleted object recovery scenarios directly.
- D. Incorrect.
Option 4: Incorrect. Geo-redundant storage (GRS) protects against regional outages by replicating data to another region, but it does not preserve previous versions of objects or enable recovery of deleted data. If an object is deleted or overwritten, that change replicates to the secondary region as well.
