Zorluk: OrtaConfigure Blob Storage Lifecycle and Replication

An administrator manages an Azure storage account named `storage1` that is configured to use Geo-Redundant Storage (GRS). Due to a severe regional outage in the primary region, the administrator decides to initiate a customer-managed failover for `storage1`. Which replication configuration will `storage1` have immediately after the failover completes?

  1. A
    Geo-Redundant Storage (GRS) in the secondary region, with replication automatically established back to the primary region
  2. B
    Zone-Redundant Storage (ZRS) in the secondary region
  3. Locally Redundant Storage (LRS) in the secondary regionCevap
  4. D
    Read-Access Geo-Redundant Storage (RA-GRS) in the secondary region

Cevap

Locally Redundant Storage (LRS) in the secondary region.
When you initiate a failover for a Geo-Redundant Storage (GRS) account, the secondary region becomes the new primary region. During this process, the storage account is automatically converted to Locally Redundant Storage (LRS) in the new primary region. If you want to restore geo-redundancy, you must manually reconfigure the replication settings to GRS or RA-GRS after the failover completes.

Adım Adım Çözüm

1
Analyze the starting replication configuration and the triggered event.
The storage account is configured as Geo-Redundant Storage (GRS) and a customer-managed failover is initiated due to a regional outage.
Determining the initial configuration is essential to predict the post-failover state of the storage account.
2
Determine the automatic replication state transition that occurs during failover.
During the failover process, the secondary region becomes the new primary region, and the replication type is downgraded to Locally Redundant Storage (LRS).
Azure automatically converts GRS and RA-GRS storage accounts to LRS in the target region to complete the failover.
3
Verify if manual intervention is required to restore high availability.
To restore geo-redundant replication, the administrator must manually reconfigure the storage account back to GRS or RA-GRS once the original region is available.
This confirms that the immediate post-failover state is non-redundant (LRS).

Anahtar Kavram

When a customer-managed failover is initiated for an Azure storage account configured with Geo-Redundant Storage (GRS), the secondary region becomes the new primary region, and the storage account's replication configuration is automatically converted to Locally Redundant Storage (LRS).
