AZ-104 Question 75
Single answerYou are managing an Azure Storage account that receives large amounts of data each day. After 30 days, the data is rarely accessed and needs to be retained cost-effectively for compliance. You want to automatically move the data to the archive tier after it remains inactive for 30 days. Which of the following configurations should you use?
- A
Create a scheduled runbook in Azure Automation to move the data to the archive tier periodically
- B
Use Azure Blob Lifecycle Management policies to automatically transition the data after 30 days
- C
Enable read-access geo-redundant storage (RA-GRS) to offload older data to a secondary region
- D
Implement an Azure Monitor alert to trigger manual archiving when data is older than 30 days
Show answer and explanation
Correct answer: B
Explanation
Azure Blob Lifecycle Management offers a built-in mechanism to move data between storage tiers based on rules you define, such as age or last access time. This is the most efficient and scalable way to automatically transition data to the archive tier after 30 days.
- A. Incorrect.
While you could manually automate transitions with Azure Automation, this approach would require ongoing script maintenance and is less efficient than a built-in policy feature.
- B. Correct.
Blob Lifecycle Management policies are designed to automate tier transitions based on rules, making them the recommended solution for automatically moving data to lower-cost tiers.
- C. Incorrect.
RA-GRS provides redundancy for read access in a secondary region but does not automatically transition data between hot, cool, or archive tiers based on access patterns or age.
- D. Incorrect.
Using Azure Monitor alerts to trigger manual actions can be helpful for notifications, but it does not automate tier transitions. You would still need to perform the archiving steps manually.
