SAP-C02 Question 205
Single answerA financial services company operates a critical payment processing application that must meet a Recovery Time Objective (RTO) of 15 minutes and a Recovery Point Objective (RPO) of 5 minutes. The company wants to implement a disaster recovery (DR) strategy that ensures minimal downtime and data loss in the event of a region-wide failure. Which DR strategy should the company choose?
- A
Backup and Restore with scheduled backups to Amazon S3
- B
Pilot Light with a scaled-down version of the application running in a secondary region
- C
Warm Standby with a scaled-down but fully functional environment in a secondary region
- D
Multi-Site with fully active environments in multiple regions
Show answer and explanation
Correct answer: D
Explanation
Given the strict RTO of 15 minutes and RPO of 5 minutes, the company needs a disaster recovery strategy that minimizes downtime and data loss. Multi-Site is the only option that ensures fully active environments in multiple regions, allowing for immediate failover with negligible disruption. Other strategies like Backup and Restore, Pilot Light, and Warm Standby are less suitable due to their longer recovery times or additional scaling requirements.
- A. Incorrect.
Backup and Restore is a cost-effective strategy but has a high RTO and RPO, making it unsuitable for meeting the strict RTO and RPO requirements of 15 minutes and 5 minutes, respectively.
- B. Incorrect.
Pilot Light provides faster recovery than Backup and Restore but still requires scaling up and configuring the secondary environment during a failover, which makes it difficult to meet the 15-minute RTO requirement.
- C. Incorrect.
Warm Standby provides a functional secondary environment, but scaling up to full capacity during a failover might exceed the 15-minute RTO requirement, especially for a critical application like payment processing.
- D. Correct.
Multi-Site operates fully active environments in multiple regions, ensuring near-zero downtime and minimal data loss. This strategy easily meets the RTO of 15 minutes and RPO of 5 minutes, making it the most appropriate choice for the scenario.
