Question 270
A team migrates a database from an on-premises SQL instance to Azure SQL Database and discovers after cutover that an essential SQL Agent job never moved. Which diagnostic evidence should the database administrator check FIRST?
Explanation
Correct Answer
Collect source version, compatibility level, blockers, logins, SQL Agent jobs, linked servers, TDE key dependencies, storage size and application integration map. This is the discriminating system or configuration evidence for the case. Successful schema import does not prove that instance-level jobs, security identities and linked dependencies survive a migration. Corresponding approach: Use a current migration assessment to inventory database dependencies, unsupported features, downtime constraints and target platform compatibility before moving data.
Incorrect Answers
Inventory SQL Agent, cross-database dependencies, instance features, latency, licensing, OS access and application connection requirements before choosing a target. These checks primarily test Choosing Azure SQL Database versus Managed Instance versus SQL VM instead of the critical system behavior in this case. Examine: Collect source version, compatibility level, blockers, logins, SQL Agent jobs, linked servers, TDE key dependencies, storage size and application integration map.
Compare database offering capabilities, deployment parameters, identity, networking, Fabric integration support, source control and tenant governance before provisioning. These checks primarily test Azure SQL deployment automation and Fabric SQL integration boundary instead of the critical system behavior in this case. Examine: Collect source version, compatibility level, blockers, logins, SQL Agent jobs, linked servers, TDE key dependencies, storage size and application integration map.
Inspect migration replication health, source change rate, lag, database compatibility, authentication, connection-string cutover and residual transaction state. These checks primarily test Online migration with controlled cutover and validation instead of the critical system behavior in this case. Examine: Collect source version, compatibility level, blockers, logins, SQL Agent jobs, linked servers, TDE key dependencies, storage size and application integration map.
