Topic 1 Question 234
A company wants to use AWS for disaster recovery for an on-premises application. The company has hundreds of Windows-based servers that run the application. All the servers mount a common share.
The company has an RTO of 15 minutes and an RPO of 5 minutes. The solution must support native failover and fallback capabilities.
Which solution will meet these requirements MOST cost-effectively?
Create an AWS Storage Gateway File Gateway. Schedule daily Windows server backups. Save the data to Amazon S3. During a disaster, recover the on-premises servers from the backup. During tailback, run the on-premises servers on Amazon EC2 instances.
Create a set of AWS CloudFormation templates to create infrastructure. Replicate all data to Amazon Elastic File System (Amazon EFS) by using AWS DataSync. During a disaster, use AWS CodePipeline to deploy the templates to restore the on-premises servers. Fail back the data by using DataSync.
Create an AWS Cloud Development Kit (AWS CDK) pipeline to stand up a multi-site active-active environment on AWS. Replicate data into Amazon S3 by using the s3 sync command. During a disaster, swap DNS endpoints to point to AWS. Fail back the data by using the s3 sync command.
Use AWS Elastic Disaster Recovery to replicate the on-premises servers. Replicate data to an Amazon FSx for Windows File Server file system by using AWS DataSync. Mount the file system to AWS servers. During a disaster, fail over the on-premises servers to AWS. Fail back to new or existing servers by using Elastic Disaster Recovery.

Considering RTO and RPO, D is correct answer A is incorrect because, thought backups are in s3, its not possible to recover ec2 within 15-minute RTO and a 5-minute RPO

You need FSx, not EFS and def not S3.

FSX for Windows and Elastic Disaster Recovery
