SAP-C02 Question 88
Single answerA global e-commerce company wants to implement a disaster recovery strategy for their order processing system, which has a strict SLA of 5 minutes for Recovery Time Objective (RTO) and near-zero Recovery Point Objective (RPO). The company also aims to minimize costs during normal operations but is willing to spend more during disaster recovery situations. Which disaster recovery strategy should they choose?
- A
Pilot Light
- B
Warm Standby
- C
Backup and Restore
- D
Multi-Site
Show answer and explanation
Correct answer: B
Explanation
Warm Standby is the most appropriate strategy for this scenario because it meets the company's strict RTO and RPO requirements while balancing costs during normal operations. Pilot Light and Backup and Restore do not meet the 5-minute RTO requirement, and Multi-Site, while effective, is unnecessarily expensive given the company's cost-minimization goal during normal operations.
- A. Incorrect.
Pilot Light is a cost-effective strategy where only the critical core components of the system are running at all times. However, it does not meet the strict RTO of 5 minutes because spinning up the remaining infrastructure would take longer.
- B. Correct.
Warm Standby keeps a scaled-down version of the system running in another region. This approach balances cost and recovery speed, making it suitable for a 5-minute RTO and near-zero RPO.
- C. Incorrect.
Backup and Restore is the cheapest option but involves restoring data from backups during a disaster, which typically results in a much longer RTO than 5 minutes.
- D. Incorrect.
Multi-Site keeps the system fully operational in multiple regions at all times, providing the best RTO and RPO. However, it is significantly more expensive during normal operations, which does not align with the company's requirement to minimize costs.
