A company needs to store quarterly compliance reports in Azure. The reports are accessed only once every few months, but must be readable immediately when requested. The system administrator plans to store the reports in the Archive access tier of Azure Blob Storage to minimize storage costs. Why is this plan inappropriate for the company's requirement?
- Data in the Archive tier is stored offline and must be rehydrated to a warmer tier before it can be read, which introduces a delay of several hours.Answer
- BData stored in the Archive tier is not managed by Microsoft, requiring the customer to perform manual operating system updates on the underlying storage servers.
- CRetrieving data from the Archive tier requires the customer to deploy and maintain a virtual machine to process the read operations.
- DStoring data in the Archive tier shifts the Azure subscription billing model from an Operational Expenditure (OpEx) to a Capital Expenditure (CapEx).
Answer
Data in the Archive tier is stored offline and must be rehydrated to a warmer tier before it can be read, which introduces a delay of several hours.
The correct answer is correct because the Archive access tier stores data offline. While it offers the lowest storage cost, the data cannot be read directly. To retrieve the data, it must first be rehydrated to the Hot or Cool tier, which introduces a retrieval latency of several hours. This makes the Archive tier inappropriate for data that must be readable immediately.
