DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
Exhibit
Refer to the exhibit. ```powershell Get-AzSqlDatabaseGeoBackup -ResourceGroupName "rg1" -ServerName "sqlserver1" -DatabaseName "db1" | Restore-AzSqlDatabase -FromGeoBackup -TargetResourceGroupName "rg2" -TargetServerName "sqlserver2" -TargetDatabaseName "db1-restored" ```
You are preparing a disaster recovery runbook. You plan to use the PowerShell command shown in the exhibit to restore a database to a different region. What must be true for this command to succeed?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The source database must have geo-redundant backup storage configured.
The Restore-AzSqlDatabase cmdlet with the -FromGeoBackup parameter requires the source database to have geo-redundant backup storage (also known as geo-redundant storage) enabled. This allows restoration from geographically replicated backups. Option B is incorrect because point-in-time restore is not required for a geo-restore; geo-restore uses the geo-redundant backup independently. Option C is incorrect because the source database does not need to be online at the time of restoration; geo-backups are stored in Azure storage and are available even if the source database is offline. Option D is incorrect because the purpose of geo-restore is to restore to a different region; therefore, the target server can be in a different region than the source.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The source database must have geo-redundant backup storage configured.
Why this is correct
Geo-restore to a different Azure region requires the source database's backup storage redundancy to be geo-redundant; locally redundant or zone-redundant backups exist only in the primary region, so no copy is available to restore elsewhere.
- ✗
The source database must have point-in-time restore enabled.
Why it's wrong here
Point-in-time restore governs recovery to a specific moment within the retention window, not cross-region capability. It is tempting because PITR is a prerequisite for many restore operations, but the command's success depends on geo-replication or geo-restore configuration, not on PITR being enabled on the source.
- ✗
The source database must be online at the time of restoration.
Why it's wrong here
A restore is precisely the operation performed when the source is unavailable, so requiring it to be online defeats disaster recovery. It is tempting because most restores run against live sources, but cross-region restore relies on replicated backups that persist independently of source availability.
- ✗
The target server must be in the same region as the source server.
Why it's wrong here
Cross-region restore explicitly targets a different region, so requiring the target server to share the source's region contradicts the scenario's goal. It is tempting because same-region restores are the common default, and geo-replication pairs servers regionally, but the command's purpose is regional failover.
