Zorluk: OrtaData Lifecycle Management and Retention

A retail company stores customer invoice PDF documents in a General-purpose v2 (GPv2) Azure Blob storage account. The documents must be managed according to the following requirements:

* Invoices must be immediately available for active customer support queries during the first 30 days after creation.
* Between 31 and 180 days after creation, invoices are rarely accessed but must still support immediate, sub-second retrieval.
* After 180 days, invoices must be retained for an additional 1,095 days to meet regulatory compliance audits. Retrieval latency of several hours is acceptable during this period.
* After the retention period, the invoices must be permanently deleted to minimize storage costs.

You need to design a 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 the blobs to the Cool tier 30 days after creation.Cevap
  2. Transition the blobs to the Archive tier 180 days after creation.Cevap
  3. C
    Transition the blobs to the Archive tier 30 days after creation.
  4. D
    Delete the blobs 1,095 days after creation.
  5. E
    Delete the blobs 180 days after creation.

Cevap

Transition the blobs to the Cool tier 30 days after creation, and transition the blobs to the Archive tier 180 days after creation.
The correct configurations are transitioning the blobs to the Cool tier after 30 days and transitioning them to the Archive tier after 180 days. The Cool tier allows sub-second retrieval which satisfies the requirement for the 31-180 days period. The Archive tier is the most cost-effective tier for the subsequent 1,095-day compliance period since retrieval latency of several hours is acceptable.

Adım Adım Çözüm

1
Analyze the access and retrieval latency requirements for each phase of the data lifecycle.
The first 30 days require Hot storage. Days 31 to 180 require storage that supports sub-second latency (Cool storage is appropriate). Days 181 to 1,275 require cost-optimized storage where high latency is acceptable (Archive storage).
To map requirements to the correct Azure Storage tiers without violating performance or latency SLA constraints.
2
Calculate the timing for the lifecycle rule transitions based on days elapsed since creation.
Transition to Cool tier occurs 30 days after creation. Transition to Archive tier occurs 180 days after creation. Deletion occurs after 180+1095=1275180 + 1095 = 1275 days.
Lifecycle policy rules evaluate conditions based on elapsed days since creation or modification.
3
Identify the incorrect actions by evaluating against latency constraints and duration calculations.
Transitioning to Archive at 30 days violates the sub-second retrieval latency between 31 and 180 days. Deletion at 180 or 1,095 days violates the required retention duration.
To filter out distractors that introduce retrieval latency issues or fail compliance retention times.
