Question

Difficulty: EasyData Lifecycle Management and Retention

A financial services provider stores daily transaction receipts in an Azure Blob Storage container. The receipts are frequently accessed for auditing within the first 7 days and must support immediate, sub-second retrieval at any time. After 7 days, the receipts are rarely accessed but must be retained for 365 days to meet regulatory compliance requirements. The provider wants to configure an Azure Blob Storage lifecycle management policy to minimize storage costs.

Which lifecycle management policy rule should you recommend?

  1. Transition the blobs to the Cool tier 7 days after creation, and delete the blobs 365 days after creation.Answer
  2. B
    Transition the blobs to the Archive tier 7 days after creation, and delete the blobs 365 days after creation.
  3. C
    Transition the blobs to the Archive tier 7 days after creation, and transition the blobs to the Cool tier 30 days after creation.
  4. D
    Transition the blobs to the Cool tier 365 days after creation, and delete the blobs 7 days after creation.

Answer

Transition the blobs to the Cool tier 7 days after creation, and delete the blobs 365 days after creation.
The correct option transitions the blobs to the Cool tier 7 days after creation and deletes them after 365 days. The Cool tier is the most cost-effective tier that still provides immediate, sub-second retrieval, which satisfies the requirement that transaction receipts must be accessible immediately. Deleting the blobs after 365 days aligns with the compliance requirement to retain data for that period.

Step-by-Step Solution

1
Analyze retrieval latency requirements.
Since sub-second retrieval is required at any time, the Archive tier cannot be used because it has a rehydration latency of several hours.
Ensures that the selected storage tier meets the performance constraints specified in the scenario.
2
Identify the optimal cost-effective tier for infrequently accessed data.
The Cool tier is selected for receipts older than 7 days, as they are rarely accessed but still require immediate retrieval.
Minimizes storage costs while adhering to the latency requirement.
3
Apply the retention period rule.
Configure the lifecycle policy to delete blobs 365 days after creation.
Fulfills the compliance mandate to keep the records for exactly 365 days.
