DP-300 Configure and manage automation of tasks Practice Question
You are designing an automated backup strategy for Azure SQL Managed Instance. The solution must ensure point-in-time restore (PITR) within 2 hours for the last 7 days and long-term retention (LTR) for 5 years. Which configuration should you use?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set PITR retention to 7 days (default) and configure LTR backup policy with yearly backups for 5 years.
Azure SQL Managed Instance supports point-in-time restore (PITR) with a configurable retention period from 1 to 35 days; the default is 7 days, which satisfies the requirement to restore within 2 hours for the last 7 days (the 2-hour target is a recovery point objective, not retention). For long-term retention (LTR) of 5 years, Managed Instance supports LTR backup policies with yearly backups that can retain backups for up to 10 years. Therefore, setting PITR retention to 7 days (default) and configuring an LTR policy with yearly backups for 5 years meets both requirements. Option A is wrong because Azure Backup for SQL Server in Azure VM is for SQL Server on Azure VMs, not for Managed Instance. Option B is wrong because "geo-redundant backup storage for LTR" is a storage redundancy option, not an LTR retention policy; LTR requires explicit backup frequency and retention configuration. Option C is wrong because PITR retention cannot be set to 2 hours (minimum is 1 day) and custom backup jobs using Elastic Database Jobs are unnecessary; Managed Instance automates backups natively.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use Azure Backup for SQL Server in Azure VM to back up the managed instance.
Why it's wrong here
Managed Instance is PaaS; Azure Backup is for IaaS.
- ✗
Set PITR retention to 7 days and use geo-redundant backup storage for LTR.
Why it's wrong here
Backup storage redundancy does not provide LTR.
- ✗
Set PITR retention to 2 hours and configure a custom backup job using Elastic Database Jobs.
Why it's wrong here
PITR retention cannot be set to 2 hours; minimum is 1 day.
- ✓
Set PITR retention to 7 days (default) and configure LTR backup policy with yearly backups for 5 years.
Why this is correct
Managed Instance supports both PITR and LTR.
