SAP-C02 Question 380
Single answerA financial institution is designing a disaster recovery (DR) strategy for its critical workloads hosted on AWS. The institution requires a solution that minimizes downtime and data loss while also being cost-efficient. Which disaster recovery strategy should the institution implement?
- 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 appropriate disaster recovery strategy in this scenario. It ensures a scaled-down version of the production environment is always running in the DR region, allowing for quick scaling during a disaster. This approach minimizes downtime and data loss while being more cost-efficient than an Active-Active setup. Pilot Light and Backup and Restore do not meet the downtime and RPO requirements, while Multi-Region Active-Active is not cost-efficient.
- A. Incorrect.
Backup and Restore is the most cost-effective option but has the highest downtime and Recovery Point Objective (RPO). This does not meet the requirement to minimize downtime and data loss.
- B. Incorrect.
Pilot Light maintains a minimal environment in the DR region. While it is cost-efficient, it involves longer recovery times compared to Warm Standby, which violates the requirement to minimize downtime.
- C. Correct.
Warm Standby keeps a scaled-down version of the environment running in the DR region. It strikes a balance between cost and recovery time, making it a suitable choice for minimizing downtime and data loss.
- D. Incorrect.
Multi-Region Active-Active provides the lowest downtime and RPO but is the most expensive option. The question explicitly requires a cost-efficient solution, so this option does not meet the requirement.
