You set Azure Blob lifecycle to move objects to the archive tier after 30 days. Customers ask for an SLA for accessing data older than 30 days. What is the minimum recovery SLA you should document for retrieving archived blobs?

The correct answer is between one and 15 hours because Azure Blob Storage's Archive tier has a typical retrieval time of 1 to 15 hours. This is a key characteristic of the Archive tier, designed for infrequently accessed data where lower cost is prioritized over immediate availability. The other options are incorrect because: "at least two days" is too long; the typical retrieval is much faster. "at least one day" is also too long, though closer, the 1-15 hour range is more precise. "between zero and 60 minutes" is too short; this retrieval time is more characteristic of the Cool or Hot tiers, not the Archive tier.
