A company is migrating an IBM Informix database to a Multi-AZ deployment of Amazon RDS for SQL Server with Always On Availability Groups (AGs). SQL Server Agent jobs on the Always On AG listener run at 5-minute intervals to synchronize data between the Informix database and the SQL Server database.
Users experience hours of stale data after a successful failover to the secondary node with minimal latency.
What should a database specialist do to ensure that users see recent data after a failover?
A. Set TTL to less than 30 seconds for cached DNS values on the Always On AG listener.
B. Break up large transactions into multiple smaller transactions that complete in less than 5 minutes.
C. Set the databases on the secondary node to read-only mode.
D. Create the SQL Server Agent jobs on the secondary node from a script when the secondary node takes over after a failure.
