Zorluk: KolayData Lifecycle Management and Retention

An organization stores application log files in an Azure Blob Storage container. The logs are frequently accessed for the first 30 days. After 30 days, the logs are rarely accessed but must be available for immediate, sub-second retrieval to support troubleshooting. The logs must be retained for a total of 365 days and then removed to minimize storage costs. Which two actions should you include in the Azure Blob Storage lifecycle management policy to meet these requirements at the lowest cost? (Select TWO.)

  1. Transition the blobs to the Cool tier 30 days after creationCevap
  2. Delete the blobs 365 days after creationCevap
  3. C
    Transition the blobs to the Archive tier 30 days after creation
  4. D
    Transition the blobs to the Archive tier 30 days after creation and configure priority rehydration

Cevap

Transitioning the blobs to the Cool tier after 30 days and deleting the blobs after 365 days.
Transitioning the blobs to the Cool tier 30 days after creation meets the requirement for lower-cost storage of rarely accessed data while maintaining sub-second retrieval times. Deleting the blobs 365 days after creation satisfies the regulatory requirement to keep logs for 365 days and then remove them to minimize storage costs.

Adım Adım Çözüm

1
Analyze the access frequency and retrieval latency requirements for the first stage.
The logs are frequently accessed for the first 30 days (Hot tier) and then rarely accessed but require immediate, sub-second retrieval. This matches the Cool tier characteristics.
The Cool tier offers lower storage costs than the Hot tier while maintaining sub-second retrieval times.
2
Evaluate the suitability of the Archive tier for the 30-day transition.
The Archive tier has retrieval latencies of several hours, which violates the requirement for immediate, sub-second troubleshooting access.
Data in the Archive tier is offline and must be rehydrated before it can be read.
3
Determine the action required at the end of the retention period.
The logs must be retained for a total of 365 days and then removed.
A delete action in the lifecycle policy 365 days after creation will remove the blobs to minimize costs.
