Zorluk: OrtaConfigure Blob Storage Lifecycle and Replication

An administrator is designing a lifecycle management policy for a standard General Purpose v2 (GPv2) storage account named stdata2026. The policy must transition blobs to the Cool tier if they have not been read or written to for more than 30 days. Which of the following actions must the administrator perform first to ensure the lifecycle policy executes correctly based on this requirement?

  1. A
    Convert the storage account replication from Locally-redundant storage (LRS) to Read-access geo-redundant storage (RA-GRS).
  2. B
    Assign the Storage Blob Data Reader role to the Azure Lifecycle Management system-assigned managed identity.
  3. Enable blob last access time tracking on the storage account.Cevap
  4. D
    Configure a storage account firewall rule to allow the Azure Lifecycle Management service bypass.

Cevap

Enable blob last access time tracking on the storage account.
The correct option is to enable blob last access time tracking on the storage account. For a lifecycle policy to transition blobs based on when they were last read or written to, the policy uses the last accessed metric. On a standard GPv2 storage account, this tracking is disabled by default and must be explicitly enabled for the rules to function correctly.

Adım Adım Çözüm

1
Analyze the requirement to transition blobs based on when they were last read or written (not just modified).
This requires using the 'last accessed' property in the lifecycle management policy rules.
Standard lifecycle rules default to using the last modified or creation times unless last access time tracking is active.
2
Identify the configuration needed to support last access time tracking on a GPv2 storage account.
Blob last access time tracking must be enabled on the storage account.
Access time tracking is disabled by default to optimize performance and metadata overhead, so it must be explicitly enabled before the lifecycle policy can evaluate this criteria.

Configuring access-time-based lifecycle management rules in Azure Blob Storage requires enabling last access time tracking.
