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 the maintenance window for the Managed Instance.
Azure SQL Managed Instance automatically applies OS and SQL Server engine updates during the user-configured maintenance window, minimizing downtime by performing patching during off-peak hours. Option B is wrong because Elastic Job agents are used for scheduling T-SQL jobs across multiple databases, not for patching the instance or OS. Option C is wrong because manual patching via the Azure portal is not an automated solution and would require manual effort and cause downtime. Option D is wrong because Azure Update Manager is designed for Azure VMs and Arc-enabled servers, not for Azure SQL Managed Instance, which has its own built-in patching mechanism.
