Question

Difficulty: MediumConfigure Blob Storage Lifecycle and Replication

An administrator is managing a standard General Purpose v2 (GPv2) storage account named `strecords2026` in the West Europe region. The storage account currently uses locally-redundant storage (LRS) replication. The administrator needs to configure the storage account to use zone-redundant storage (ZRS) to protect against datacenter failures within the region. The configuration must be performed with no downtime and without migrating data to a new storage account. Which of the following actions should the administrator perform?

  1. A
    In the Configuration blade of the storage account, change the replication setting to Zone-redundant storage (ZRS) and save the changes.
  2. B
    Configure a lifecycle management policy with a rule to transition the blobs to a new container configured for ZRS.
  3. Submit a support request to Microsoft to perform a live migration of the storage account.Answer
  4. D
    Create a new GPv2 storage account with ZRS enabled in the West Europe region and use AzCopy to replicate the blobs.

Answer

Submit a support request to Microsoft to perform a live migration of the storage account.
To migrate a storage account from locally-redundant storage (LRS) to zone-redundant storage (ZRS) without downtime and keeping the same storage account, you must submit a support request to Microsoft to perform a live migration. Microsoft handles the data replication in the background while the storage account remains fully accessible.

Step-by-Step Solution

1
Identify the current replication configuration and the target redundancy requirement.
The storage account is currently configured with locally-redundant storage (LRS), and the target is zone-redundant storage (ZRS).
This determines the migration path and identifies standard support paths in Azure.
2
Evaluate the direct conversion options in the Azure portal.
Direct configuration changes from LRS to ZRS are not available in the storage account configuration blade.
Azure limits self-service replication changes primarily to upgrading to geo-redundant options like GRS.
3
Determine the method that avoids downtime and retains the same storage account.
Submitting a support request for a live migration meets these criteria.
Microsoft Support can perform a background copy to ZRS, which keeps the existing account active and preserves the endpoints.
