Which combination of steps should a solutions architect take to migrate the application with the LEAST amount of downtime?
(Choose two.)
Use an AWS Server Migration Service (AWS SMS) replication job to migrate the database server VM to AWS.
Use VM Import/Export to import the application server VM.
Export the VM images to an AWS Snowball Edge Storage Optimized device.
Use an AWS Server Migration Service (AWS SMS) replication job to migrate the application server VM to AWS.
Use an AWS Database Migration Service (AWS DMS) replication instance to migrate the database to an Amazon RDS DB instance.
Explanations:
AWS SMS is used for migrating servers, but it does not support large data migrations like 500 TB efficiently. It is better suited for smaller workloads.
VM Import/Export is useful for migrating smaller VMs, but handling 500 TB of data using this method would not be efficient for minimal downtime.
Using AWS Snowball Edge for 500 TB of data would involve significant time and manual steps, increasing downtime. It’s not ideal for this scenario.
AWS SMS supports live migration of VMs, which can minimize downtime during the application server migration. It is suitable for this use case.
AWS DMS allows for near-zero downtime migrations of databases and can replicate data from SQL Server to Amazon RDS, which is appropriate for this task.
