A media company keeps raw footage that editors revisit about twice a year, but editors need it retrievable immediately when requested. Which Blob Storage access tier gives the best balance of storage cost and instant access here?
Show answer and explanation
Answer: D
The Cool tier has lower storage prices than Hot and is designed for data accessed infrequently, with a minimum retention of 30 days, while still serving reads immediately. Archive is cheaper still, but archived blobs must be rehydrated first, which can take hours, so it fails the immediate-access need. Hot is priced for frequent access and costs more to store idle data, and Premium block blob targets low-latency workloads at a higher price.
Why the other options are wrong
- A. Hot tier suits frequently accessed data and charges more per gigabyte to store, which wastes money on footage that is only needed about twice a year.
- B. Premium block blob storage is aimed at low-latency, high-transaction workloads and costs considerably more to store, so it overspends for infrequently used footage.
- C. Archive blobs are offline and need rehydration that can take hours, so editors could not get the footage immediately, which breaks the stated requirement.
