HOTSPOT
You are designing a solution to store flat files.
You need to recommend a storage solution that meets the following requirements:
– Supports automatically moving files that have a modified date that is older than one year to an archive in the data store
– Minimizes costs
A higher latency is acceptable for the archived files.
Which storage location and archiving method should you recommend? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
Answer: 
Explanation:
Storage location: Azure Blob Storage
Archiving method: A lifecycle management policy
Azure Blob storage lifecycle management offers a rich, rule-based policy for GPv2 and Blob storage accounts. Use the policy to transition your data to the appropriate access tiers or expire at the end of the data’s lifecycle.
The lifecycle management policy lets you:
– Transition blobs to a cooler storage tier (hot to cool, hot to archive, or cool to archive) to optimize for performance and cost
– Delete blobs at the end of their lifecycles
– Define rules to be run once per day at the storage account level
– Apply rules to containers or a subset of blobs
