Zorluk: Çok zorConfigure Blob Storage Lifecycle and Replication

An administrator is configuring storage replication and blob lifecycle management policies for several standard General Purpose v2 (GPv2) storage accounts in an Azure subscription.

Which two of the following statements correctly describe the behavior or requirements of these configurations? (Select two.)

  1. A live migration from Locally Redundant Storage (LRS) to Zone-Redundant Storage (ZRS) cannot begin if the storage account contains any blobs currently in the Archive tier.Cevap
  2. A lifecycle policy rule designed to transition base blobs to the Archive tier will fail to transition a blob if the blob has associated snapshots that are not also transitioned to the Archive tier.Cevap
  3. C
    Changing the replication setting of a storage account from Locally Redundant Storage (LRS) to Geo-Redundant Storage (GRS) automatically creates a new storage account with a unique name, requiring all client application connection strings to be updated.
  4. D
    After a customer-managed failover of a Geo-Redundant Storage (GRS) account to the secondary region, the replication configuration automatically remains GRS, and data replication to the original primary region resumes immediately.
  5. E
    To execute a lifecycle policy rule that deletes blobs, you must assign the Storage Blob Data Owner Role-Based Access Control (RBAC) role to the storage account's system-assigned managed identity.

Cevap

A live migration from Locally Redundant Storage (LRS) to Zone-Redundant Storage (ZRS) cannot begin if the storage account contains any blobs currently in the Archive tier, and a lifecycle policy rule designed to transition base blobs to the Archive tier will fail to transition a blob if the blob has associated snapshots that are not also transitioned to the Archive tier.
The statement about LRS to ZRS live migration is correct because Azure prohibits ZRS migration while blobs remain in the Archive tier. The statement about lifecycle policy rules is correct because a base blob cannot be transitioned to the Archive tier if its associated snapshots are in Hot or Cool; both the base blob and its snapshots must be transitioned together using the rule actions.

Adım Adım Çözüm

1
Evaluate ZRS migration prerequisites.
Identify that the presence of archived blobs blocks live migration from LRS to ZRS until they are rehydrated.
Azure requires all data to be in an online tier (Hot or Cool) to perform the live replication migration to ZRS.
2
Examine lifecycle management rule mechanics with snapshots.
Recognize that a base blob cannot be archived while its snapshots remain in an online tier.
Azure Storage policy enforcement requires consistency between base blobs and snapshots when moving to the offline Archive tier.
3
Analyze the impact of modifying replication configuration.
Determine that updating LRS to GRS changes replication in-place without generating a new storage account or changing primary connection strings.
Azure handles replication transitions at the service level, preserving existing endpoints.
4
Review failover behavior.
Verify that a geo-failover converts the replication type to LRS in the secondary region.
Re-protecting the account to configure geo-redundancy back to the primary region is a manual post-failover administrative step.
5
Evaluate lifecycle policy execution permissions.
Confirm that lifecycle rules run natively without requiring RBAC roles or managed identities.
Lifecycle management is a native control-plane feature that executes actions internally.
