SAP-C02 Question 90
Single answerA company runs critical workloads on-premises and wants to implement a disaster recovery strategy using AWS. They require minimal downtime in case of a disaster and need the recovery environment to be ready to handle production traffic within minutes. Cost is a secondary concern compared to recovery speed. Which disaster recovery strategy is most appropriate for this requirement?
- A
Backup and Restore
- B
Pilot Light
- C
Warm Standby
- D
Multi-Site
Show answer and explanation
Correct answer: C
Explanation
The Warm Standby disaster recovery strategy is the best fit for the given scenario because it provides a balance between cost and recovery speed. In a Warm Standby setup, a scaled-down version of the environment is always running in AWS, which can be quickly scaled up to handle production traffic in case of a disaster. This ensures minimal downtime while keeping costs lower than a fully active Multi-Site setup.
- A. Incorrect.
Backup and Restore is the most cost-effective option but has the slowest recovery time, as it requires setting up infrastructure and restoring data before workloads can be operational. This does not meet the company's requirement for minimal downtime.
- B. Incorrect.
Pilot Light maintains a minimal version of the production environment in AWS, but it requires additional time to scale up the environment and make it production-ready. This may not meet the requirement for recovery within minutes.
- C. Correct.
Warm Standby is a scaled-down version of a fully functional environment that can be quickly scaled up to handle production traffic. This strategy balances cost and recovery speed, making it suitable for the requirement of minimal downtime.
- D. Incorrect.
Multi-Site involves running fully active environments in both on-premises and AWS simultaneously. While this strategy offers the fastest recovery time, it is the most expensive, and the scenario states that cost is a secondary concern, not the primary driver.
