Zorluk: OrtaData Lifecycle Management and Retention

An enterprise deploys an application that uploads telemetry data to a General-purpose v2 (GPv2) storage account. The telemetry files must be managed according to the following requirements:

- Telemetry files are actively analyzed for the first 30 days and require sub-second access.
- Between 30 and 90 days, the files are accessed occasionally for reporting. Sub-second access is still required, but storage costs must be minimized.
- After 90 days, the files are retained solely for compliance auditing. Retrieval latency can be up to 15 hours.
- All telemetry files must be permanently deleted after 365 days.

You need to design an Azure Blob Storage lifecycle management policy to meet these requirements while minimizing costs.

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

  1. Transition blobs to the Cool tier 30 days after creation.Cevap
  2. Transition blobs to the Archive tier 90 days after creation.Cevap
  3. C
    Transition blobs to the Archive tier 30 days after creation.
  4. D
    Transition blobs to the Archive tier immediately upon creation, and use high-priority rehydration for sub-second read requests.

Cevap

Include the actions to transition blobs to the Cool tier 30 days after creation, and transition blobs to the Archive tier 90 days after creation.
Transitioning to the Cool tier after 30 days reduces storage costs while maintaining sub-second latency for occasional reports. Transitioning to the Archive tier after 90 days offers the lowest cost for long-term audit logs that can tolerate hours of retrieval latency.

Adım Adım Çözüm

1
Analyze the active analysis phase requirements.
Telemetry files require Hot tier placement initially to support active analysis with sub-second latency for the first 30 days.
Hot tier provides the lowest access cost and sub-second latency, ideal for active analysis.
2
Evaluate the 30-to-90-day reporting phase requirements.
Transition the files to the Cool tier after 30 days.
Cool tier offers lower storage costs than Hot tier while maintaining sub-second retrieval latency, which is required for reporting.
3
Evaluate the post-90-day compliance auditing phase requirements.
Transition the files to the Archive tier after 90 days.
The Archive tier offers the lowest storage costs. The retrieval latency of up to 15 hours is acceptable for compliance audits that do not require immediate access.
