SAP-C02 Question #694: Real Exam Question with Answer & Explanation

Question

A company has developed an application that is running Windows Server on VMware vSphere VMs that the company hosts on premises. The application data is stored in a proprietary format that must be read through the application. The company manually provisioned the servers and the application. As part of its disaster recovery plan, the company wants the ability to host its application on AWS temporarily if the company's on-premises environment becomes unavailable. The company wants the application to return to on-premises hosting after a disaster recovery event is complete. The RPO is 5 minutes. Which solution meets these requirements with the LEAST amount of operational overhead?

Options

• AConfigure AWS DataSync. Replicate the data to Amazon Elastic Block Store (Amazon EBS)
• BConfigure AWS Elastic Disaster Recovery. Replicate the data to replication Amazon EC2
• CProvision an AWS Storage Gateway file gateway. Replicate the data to an Amazon S3 bucket.
• DProvision an Amazon FSx for Windows File Server file system on AWS. Replicate the data to the

Explanation

AWS Elastic Disaster Recovery (DRS) is purpose-built for exactly this scenario - it continuously replicates on-premises servers (including VMware VMs running Windows) to AWS with sub-5-minute RPO, handles automated failover to EC2 instances, and crucially supports failback to on-premises once the disaster event ends, all with minimal manual configuration.

Why the distractors fail:

• A (DataSync + EBS): DataSync is a data migration/transfer service, not a DR orchestration tool - it replicates data but doesn't provision or manage running application servers, requiring significant manual work to restore service.
• C (Storage Gateway + S3): Storage Gateway provides hybrid storage access, not application-level DR; it also doesn't address server failover or failback.
• D (FSx for Windows): FSx is a managed file system, not a DR platform - it could store files but can't replicate or orchestrate the full application stack across environments.

Memory tip: The phrase "return to on-premises after a disaster recovery event" is a strong signal for Elastic Disaster Recovery - it's the only AWS service with built-in failback capability baked in. If you see VMware + Windows + failback + low RPO, DRS is almost always the answer.
