Server Migration Service Overview

Correct Answer: Windows Server 2003

AWS Server Migration Service (SMS) relies on EC2-supported operating systems and the underlying VM Import/Export compatibility. Windows Server 2003 is end-of-life and not supported for import or migration to EC2 via SMS. In contrast, Windows Server 2008, 2012, and 2019 are supported versions for migration, making Windows Server 2003 the only unsupported option listed.

Correct Answer: It facilitates incremental replication of live server volumes.

AWS Server Migration Service (SMS) is an agentless service which facilitates the migration of on-premises server workloads to AWS. One of the key features of AWS SMS is that it supports incremental replication. This means that after the initial baseline replication of a server's volumes, only the changed blocks are replicated. This minimizes network bandwidth usage and speeds up the replication process, hence making the incremental replication method extremely efficient for migrating live server volumes. Other answers are incorrect because AWS SMS does not require physical hardware appliances to be installed on-site; it operates agentlessly. Moreover, AWS SMS is not limited to one-time full server volume replications; it is specifically designed to handle ongoing, incremental replications. Lastly, it is not restricted to replicating servers running within AWS regions; in fact, its primary purpose is to migrate on-premises servers into AWS.

Correct Answer: Replication jobs

The feature of AWS Server Migration Service that aids in automating, scheduling, and tracking incremental replications of live server volumes is known as 'Replication jobs'. Replication jobs are pivotal when it comes to large-scale server migrations as they allow for incremental synchronization of server volumes to AWS. This capability is essential to ensure that the server migration process is efficient and minimizes downtime and data transfer costs. The option 'Persistent snapshots' isn't the best answer because, although AWS SMS does use snapshots as a part of the replication process, the snapshots themselves are not used to automate, schedule, and track replications. 'Dedicated host deployments' is incorrect because this term is related to allocating a physical EC2 server for your use, and does not relate to the incremental replication feature of the server migration service. 'AMI generation blueprints' does not accurately describe a feature of the AWS Server Migration Service and therefore does not address the question about automating, scheduling, and tracking incremental replications.
