DP-300 Configure and manage automation of tasks Practice Question
You are managing an Azure SQL Managed Instance that hosts a critical database. You need to automate the export of daily backups to a storage account for long-term retention. The solution must minimize administrative overhead and support point-in-time restore within the retention period. What should you use?
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
✓
Configure a long-term retention (LTR) backup policy for the Managed Instance.
Azure SQL Managed Instance supports configuring a long-term retention (LTR) backup policy that automatically stores backups in a geo-redundant storage account for up to 10 years, minimizing administrative overhead while supporting point-in-time restore within the retention period. Option B is incorrect because Azure Backup is designed for IaaS VMs and other workloads, not for SQL Managed Instance native backups. Option C is incorrect because scheduling BACPAC exports is not a backup solution — it does not support point-in-time restore and requires manual setup. Option D is incorrect because using SQL Agent jobs with BACKUP DATABASE TO URL adds complexity and does not integrate with Azure's automated backup management.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Configure a long-term retention (LTR) backup policy for the Managed Instance.
Why this is correct
LTR policies automate backup exports to storage accounts and support point-in-time restore.
- ✗
Configure an Azure Backup policy for the Managed Instance.
Why it's wrong here
Azure Backup is not the native backup solution for Managed Instance and adds complexity.
- ✗
Schedule a BACPAC export of the database to the storage account.
Why it's wrong here
BACPAC is for schema and data export, not for backup and point-in-time restore.
- ✗
Create a SQL Agent job to perform backups using BACKUP DATABASE TO URL.
Why it's wrong here
SQL Agent jobs require manual creation and maintenance, increasing overhead.
