SAP-C02 Question 209
Single answerA financial services company operates its critical applications in an on-premises data center and is looking to implement a disaster recovery (DR) solution on AWS. The company requires minimal downtime and data loss during a disaster while keeping costs optimized. Which disaster recovery strategy on AWS is the most suitable for their requirements?
- A
Backup and Restore
- B
Pilot Light
- C
Warm Standby
- D
Multi-Region Active-Active
Show answer and explanation
Correct answer: C
Explanation
Warm Standby is the most suitable disaster recovery strategy for this scenario because it provides a balance between cost and recovery time. It involves keeping a scaled-down version of the workload running in the disaster recovery region, enabling quick scaling to full capacity in the event of a disaster. This approach ensures compliance with the company’s requirements for minimal downtime and data loss while remaining cost-effective compared to more expensive options like Multi-Region Active-Active.
- A. Incorrect.
Backup and Restore is a cost-effective solution but involves significant downtime and data loss during recovery, which does not meet the company’s requirements for minimal downtime.
- B. Incorrect.
Pilot Light is a low-cost option where only the critical core components are always running. However, scaling it up to full production during a disaster can cause delays, which may not meet the company's minimal downtime requirement.
- C. Correct.
Warm Standby maintains a scaled-down version of the application in the disaster recovery region, offering a balance between cost and downtime. It ensures faster recovery with minimal data loss, making it suitable for the company's requirements.
- D. Incorrect.
Multi-Region Active-Active provides the highest availability and minimal downtime by running identical workloads in multiple regions simultaneously. However, this approach is significantly more expensive and may exceed the company’s cost optimization goals.
