Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 234 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 234
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

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?

  • A. 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.
  • B. 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.
  • C. 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.
  • D. 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.

Selected Answer: D
