A retail organization stores daily transaction logs in an Azure Blob storage container. These logs must be retained for five years to meet regulatory compliance standards. While the logs are rarely accessed, any retrieval request must be processed immediately to resolve customer disputes. To minimize storage costs, an IT administrator proposes modifying the lifecycle management policy to transition the logs to the Archive access tier immediately after creation. Which of the following statements correctly evaluates the administrator's proposal?
- The proposal is invalid because data in the Archive tier is stored offline and cannot be read immediately, as it requires several hours to rehydrate to the Hot or Cool tier.Answer
- BThe proposal is valid because the Archive tier offers the lowest storage costs and supports immediate, low-latency read access for individual blobs under 10 MB.
- CThe proposal is invalid because managing storage tiers is an IaaS responsibility, meaning the organization must deploy and maintain virtual machines to host the storage servers.
- DThe proposal is valid because Azure Lifecycle Management automatically and instantly rehydrates archived blobs to the Hot tier when a read request is initiated.
Answer
The proposal is invalid because data in the Archive tier is stored offline and cannot be read immediately, as it requires several hours to rehydrate to the Hot or Cool tier.
The correct option is that the proposal is invalid because data in the Archive tier is offline and requires several hours to rehydrate. The Archive access tier offers the lowest storage costs but does not support direct or immediate read operations. To read data, it must first be rehydrated to an online tier (Hot or Cool), which takes hours.
