An administrator is configuring backups for resources in a multi-region Azure environment. The resources are deployed as shown in the following table:
| Subscription | Resource Group | Resource Name | Resource Type | Azure Region |
|---|---|---|---|---|
| Sub-Core-Prod | rg-compute-east | vm-prod-east | Virtual machine | East US |
| Sub-Core-Prod | rg-compute-west | vm-prod-west | Virtual machine | West US |
| Sub-Core-Prod | rg-storage-west | sa-data-west | Storage account (blobs) | West US |
| Sub-Mgmt-Backup | rg-backups-east | rsv-backup-east | Recovery Services Vault | East US |
| Sub-Mgmt-Backup | rg-backups-west | bv-backup-west | Backup Vault | West US |
Which backup or restore configuration can be successfully implemented for these resources?
- Back up vm-prod-east to rsv-backup-east.Answer
- BBack up vm-prod-west to rsv-backup-east.
- CBack up the blob containers in sa-data-west to bv-backup-west by relying on the administrator's Owner role at the subscription level, without assigning roles to the Backup Vault's managed identity.
- DRestore vm-prod-east using the 'Create new' restore option to overwrite the existing virtual machine disks while preserving its private IP address.
Answer
Back up vm-prod-east to rsv-backup-east.
The configuration to back up the virtual machine in the East US region to the Recovery Services Vault in the East US region is valid because Azure Backup supports cross-subscription virtual machine backups as long as the source virtual machine and the target vault reside in the same Azure region.
Step-by-Step Solution
Key Concept
Recovery Services Vaults require virtual machines to be in the same region to configure backups, but support cross-subscription configurations under the same tenant.
