AZ-305 Question 125
Select 2A retail organization stores large volumes of unstructured data (transaction logs, images, and documents) in Azure Blob Storage. They need to retain daily restore points for 30 days to recover from accidental deletions or corruption. The organization wants a minimal-maintenance backup solution that can be easily scaled. Which TWO recommendations should you include in your backup and recovery strategy?
- A
Use read-access geo-redundant storage (RA-GRS) to provide daily backup and restore capabilities.
- B
Enable Blob Versioning and Soft Delete at the container level.
- C
Create an automated AzCopy script to move data to a separate storage account daily.
- D
Configure Azure Backup to protect Blob Storage data on a scheduled basis.
Show answer and explanation
Correct answers: B, D
Explanation
For a low-maintenance, scalable approach, you should combine native Azure capabilities specifically designed for Blob data protection. Enabling Blob Versioning and Soft Delete helps you recover from accidental changes on the same storage account, while Azure Backup provides scheduled recovery points with policy management. Refer to Microsoft’s documentation on Azure Blob Storage backup (https://docs.microsoft.com/azure/storage/blobs/storage-blob-backup-restore) and Azure Backup (https://docs.microsoft.com/azure/backup/) for best practices and implementation details.
- A. Incorrect.
Option 1: RA-GRS replicates your data to a secondary region for disaster recovery purposes, but it does NOT provide point-in-time backups or versioning for accidental deletions or corruption. It ensures availability if the primary region fails, but it won’t allow reverting to a previous object version.
- B. Correct.
Option 2: Enabling Blob Versioning and Soft Delete allows you to maintain older versions of the objects and to recover previously deleted items. This is a proven approach to protect against accidental deletions or overwrites while staying within the same storage account.
- C. Incorrect.
Option 3: Manually copying data with AzCopy could achieve your goal, but it is more error-prone and requires additional overhead. It doesn’t integrate as seamlessly into the Azure ecosystem for scheduling and automated recovery as a first-class solution.
- D. Correct.
Option 4: Using Azure Backup for Blob Storage schedules backups automatically and offers a more straightforward management experience. It also provides centralized monitoring and policy-based retention, simplifying long-term backup needs and recovery scenarios.
