Zorluk: OrtaData Lifecycle Management and Retention

A research institution stores daily climate simulation datasets in a General-purpose v2 (GPv2) Azure Blob Storage account. The datasets are initially written to the Hot storage tier. You are designing a lifecycle management policy to meet the following requirements:

* The datasets are frequently and actively analyzed for the first 60 days after they are generated.
* After 60 days, the datasets are rarely accessed but must be retained for exactly 7 years (2,555 days) to comply with data retention regulations.
* Any rare data retrieval after 60 days must be completed within a maximum of 15 hours.
* Storage costs must be minimized.

Which two actions should you include in the lifecycle management policy? (Select two.)

  1. Transition the datasets to the Archive tier 60 days after creation.Cevap
  2. Delete the datasets 2,555 days after creation.Cevap
  3. C
    Transition the datasets to the Archive tier 30 days after creation.
  4. D
    Transition the datasets to the Archive tier immediately upon creation.

Cevap

To satisfy the requirements, the lifecycle policy must transition the datasets to the Archive tier 60 days after creation, and delete the datasets 2,555 days after creation.
Transitioning the datasets to the Archive tier 60 days after creation ensures they remain in the Hot tier during the active analysis period while minimizing long-term storage costs. Since the latency tolerance after 60 days is 15 hours, the Archive tier's standard rehydration time is acceptable. Deleting the datasets 2,555 days (7 years) after creation ensures compliance is met without paying for storage indefinitely.

Adım Adım Çözüm

1
Analyze the active usage window and tier requirements.
The datasets are actively analyzed for the first 60 days, requiring them to remain in the Hot tier to avoid retrieval latency and transaction costs.
Ensures immediate access performance is maintained for the active 60-day analysis period.
2
Evaluate the archival transition point and latency constraints.
Transition the datasets to the Archive tier after 60 days.
Since standard rehydration takes up to 15 hours and matches the 15-hour retrieval tolerance, transitioning directly to the Archive tier after 60 days minimizes storage costs without violating latency limits.
3
Determine the lifecycle deletion schedule.
Configure a deletion action to execute 2,555 days after creation.
Ensures the 7-year retention rule is precisely met, avoiding any ongoing storage charges once the retention period ends.
