Q2 Single choice

A company runs critical workloads in an on-premises data center. The company wants to implement an AWS based disaster recovery (DR) solution that will achieve an RTO of less than 1 hour. The company needs to continuously replicate physical and virtual servers. The company must optimize costs for data storage and bandwidth usage. The DR solution must be automated.

Which solution will meet these requirements?

A
Use AWS Backup to directly replicate the on-premises servers to AWS. Enable cross-Region backup copying and data vaulting. Configure recovery points to match the defined RTO. Use AWS Step Functions to automate recovery steps.
B
Configure an AWS Storage Gateway Volume Gateway to use Amazon Elastic Block Store (Amazon EBS) snapshots for recovery. Configure AWS Backup to manage the snapshots. Create automated recovery procedures.
C
Enable AWS Elastic Disaster Recovery. Configure replication agents to continuously replicate each on-premises server. Enable the default staging area subnet configuration.
D
Create an AWS Direct Connect connection between the on-premises data center and AWS. Configure Amazon EventBridge to monitor for failures and to invoke AWS Lambda functions that launch preconfigured Amazon EC2 instances from AMIs in the event of an incident.
