SAP-C02 Question 89
Single answerA financial services company needs to implement a disaster recovery strategy for their application hosted on AWS. The application processes sensitive transactions and requires a recovery time objective (RTO) of 1 hour and a recovery point objective (RPO) of 15 minutes. The company also wants to minimize ongoing costs while ensuring a reliable recovery process. Which disaster recovery strategy should they choose?
- A
Backup and Restore
- B
Pilot Light
- C
Warm Standby
- D
Multi-Site
Show answer and explanation
Correct answer: C
Explanation
Warm Standby is the appropriate disaster recovery strategy in this scenario because it meets the company's RTO of 1 hour and RPO of 15 minutes while keeping costs lower than a fully redundant Multi-Site strategy. The scaled-down environment ensures a faster recovery compared to Pilot Light and Backup and Restore.
- A. Incorrect.
Backup and Restore is not suitable because it has a high RTO and RPO. Data restoration can take significant time, which does not meet the company's 1-hour RTO requirement.
- B. Incorrect.
Pilot Light is more cost-effective than Warm Standby, but it still requires additional time to scale the minimal environment to full production. This might not meet the RTO of 1 hour.
- C. Correct.
Warm Standby is the correct choice because it strikes a balance between cost and recovery speed. It maintains a scaled-down version of the application environment, which can be scaled up quickly to meet the RTO and RPO requirements.
- D. Incorrect.
Multi-Site is the most expensive option as it involves running fully redundant environments in multiple locations. While it provides the fastest recovery, it exceeds the company's requirement to minimize ongoing costs.
