Running a RAC cluster on EC2 doesn't meet the solution required.

A Data Pump export would work, but it will not meet the 5 minutes outage allowed.

Using DMS in CDC mode will allow the application to take only a minimal outage and is the correct answer.

SCT is typically used for changing a database engine and is not required in this scenario.

2. 3

You can use S3 cross-region replication and restore, but there will be a long downtime, so this is not the best solution.

Using DMS will allow a migration with minimal downtime, so this is the best solution.

There is no cross-region replication for RDS SQL Server.

This is a method to reduce storage allocated but it will involve downtime.

Using CDC will allow the storage to be reduced with minimal downtime and is the best solution.

Using a backup and restore method may reduce storage needs but it...
