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
✓
Azure SQL Database long-term retention (LTR) backup policy
Only Azure SQL Database long-term retention (LTR) backup policy provides automated long-term backup retention for Azure SQL Database (PaaS), allowing retention beyond the default 7-35 days up to 10 years. Option C (Azure Backup for SQL Server in Azure VMs) is for SQL Server on Azure VMs (IaaS), not for Azure SQL Database, so it does not apply. The other options (A, B, D) do not provide automated backup with long-term retention for Azure SQL Database.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Azure Site Recovery
Why it's wrong here
Azure Site Recovery is a disaster recovery solution, not a backup service for long-term retention of Azure SQL Database.
- ✗
Azure Blob Storage snapshots
Why it's wrong here
Azure Blob Storage snapshots can provide point-in-time copies, but they are not an automated backup service for Azure SQL Database and do not offer long-term retention policies.
- ✗
Azure Backup for SQL Server in Azure VMs
Why it's wrong here
Azure Backup for SQL Server in Azure VMs is designed for SQL Server running on Azure Virtual Machines (IaaS), not for Azure SQL Database (PaaS). It does not apply here.

Azure Storage lifecycle management
Why it's wrong here
Azure Storage lifecycle management manages blob storage tiers, not automated backups of Azure SQL Database with long-term retention.
- ✓
Azure SQL Database long-term retention (LTR) backup policy
Why this is correct
Azure SQL Database long-term retention (LTR) backup policy is the built-in feature that allows configuring retention up to 10 years, beyond the default 7-35 days.
