Question

Difficulty: HardConfigure Blob Storage Lifecycle and Replication

You manage two General Purpose v2 (GPv2) storage accounts in the East US region:

* `storage1`: Configured with Locally Redundant Storage (LRS).
* `storage2`: Configured with Zone-Redundant Storage (ZRS).

You need to update the replication configuration of both storage accounts to meet the following requirements:

* Replicate all data to a secondary region (West US).
* Maintain zone redundancy in the primary region.
* Ensure there is no downtime or data loss during the configuration change.
* Avoid manual data replication.

Which two actions should you perform?

  1. For storage2, change the replication setting to Geo-zone-redundant storage (GZRS) in the Azure portal.Answer
  2. For storage1, submit a support request to Microsoft to perform a live migration to Geo-zone-redundant storage (GZRS).Answer
  3. C
    For storage1, change the replication setting to Geo-zone-redundant storage (GZRS) in the Azure portal.
  4. D
    For storage2, submit a support request to Microsoft to perform a live migration to Geo-zone-redundant storage (GZRS).

Answer

To meet the requirements, you should change the replication setting of storage2 to Geo-zone-redundant storage (GZRS) in the Azure portal, and submit a support request to Microsoft to perform a live migration to Geo-zone-redundant storage (GZRS) for storage1.
To maintain zone redundancy in the primary region and replicate to a secondary region, the storage accounts must use Geo-zone-redundant storage (GZRS). For the storage account configured with ZRS (storage2), converting to GZRS is a self-service operation that can be performed directly in the Azure portal. For the storage account configured with LRS (storage1), converting to GZRS cannot be done via self-service and requires submitting a support request to Microsoft to perform a live migration, which avoids downtime and data copying.

Step-by-Step Solution

1
Determine the required replication type.
Both storage accounts must be zone-redundant in East US and geo-replicated to West US, which requires Geo-zone-redundant storage (GZRS).
GZRS replicates data synchronously across three Azure availability zones in the primary region and asynchronously to a secondary region.
2
Evaluate the migration path for storage2.
Changing from Zone-Redundant Storage (ZRS) to Geo-zone-redundant storage (GZRS) is supported as a direct self-service conversion.
Azure allows self-service changes from ZRS to GZRS directly from the Azure portal, PowerShell, or Azure CLI.
3
Evaluate the migration path for storage1.
Changing from Locally Redundant Storage (LRS) to Geo-zone-redundant storage (GZRS) requires a live migration.
Self-service conversion from LRS directly to GZRS is not supported. To avoid downtime and manual copy, a support ticket must be submitted for a Microsoft-managed live migration.
