AWS Certified Solutions Architect – Professional — Question 812
A company is using a lift-and-shift strategy to migrate applications from several on-premises Windows servers to AWS. The Windows servers will be hosted on
Amazon EC2 instances in the us-east-1 Region.
The company's security policy allows the installation of migration tools on servers. The migration data must be encrypted in transit and encrypted at rest. The applications are business critical. The company needs to minimize the cutover window and minimize the downtime that results from the migration. The company wants to use Amazon CloudWatch and AWS CloudTrail for monitoring.
Which solution will meet these requirements?
Answer options
- A. Use AWS Application Migration Service (CloudEndure Migration) to migrate the Windows servers to AWS. Create a Replication Settings template. Install the AWS Replication Agent on the source servers.
- B. Use AWS DataSync to migrate the Windows servers to AWS. Install the DataSync agent on the source servers. Configure a blueprint for the target servers. Begin the replication process.
- C. Use AWS Server Migration Service (AWS SMS) to migrate the Windows servers to AWS. Install the SMS Connector on the source servers. Replicate the source servers to AWS. Convert the replicated volumes to AMIs to launch EC2 instances.
- D. Use AWS Migration Hub to migrate the Windows servers to AWS. Create a project in Migration Hub. Track the progress of server migration by using the built- in dashboard.
Correct answer: A
Explanation
AWS Application Migration Service (MGN) is the primary AWS service for lift-and-shift server migrations, utilizing continuous block-level replication via an agent installed on the source servers to minimize downtime and the cutover window. It natively supports encryption in transit and at rest, and integrates fully with Amazon CloudWatch and AWS CloudTrail for monitoring. Other options like AWS DataSync are intended for data transfer rather than OS-level migrations, while AWS SMS is a legacy agentless tool that does not meet the low-downtime requirements as effectively as MGN.
