AZ-305 · Question 23 · Domain 2.3: Recommend a data storage solution
A media company stores 500 TB of video files in an Azure Storage account.
Data access patterns show that videos are accessed frequently during the first 30 days after upload. From day 31 to 180, they are accessed rarely but must be available immediately if requested. After 180 days, they are kept only for compliance and are almost never accessed, but must be retained for 5 years.
You need to design a cost-optimized storage solution. What should you configure?
Answer options:
An Azure Automation runbook that runs a PowerShell script daily to change the access tier of blobs based on their creation date.
A Blob Lifecycle Management policy to move blobs to Cool tier after 30 days, and to Archive tier after 180 days.
Set the default account access tier to Cool, and use a Lifecycle Management policy to move blobs to Archive after 180 days.
Use Azure Data Factory to copy blobs older than 180 days to a separate Archive storage account.
