A company plans to store archival data in Azure Blob Storage. The data will be accessed less than once a year, and a retrieval latency of several hours is acceptable. The company wants to minimize storage costs. Which storage access tier should they use?
- The Archive tier, which offers the lowest storage cost but requires data rehydration before it can be read.Answer
- BThe Cool tier, because data placed in the Archive tier is permanently locked and can never be retrieved.
- CThe Archive tier, with the expectation that Microsoft will manage and patch the operating system of the storage account host to enable direct reads.
- DThe Archive tier, but they must apply a ReadOnly resource lock to the storage account to authorize user read access.
Answer
The Archive tier, which offers the lowest storage cost but requires data rehydration before it can be read.
The Archive tier is designed for data that is rarely accessed and can tolerate retrieval latency. It offers the lowest storage costs among all Azure Blob Storage tiers, but the data must be rehydrated to a Hot or Cool tier before it can be read.
