SAP-C02 Question 501
Single answerA financial services company wants to implement a disaster recovery (DR) strategy for their critical applications hosted in AWS. They require minimal downtime in the event of a disaster, but they also want to optimize costs by not running a fully duplicated production environment continuously. Which DR strategy should they choose?
- A
Pilot Light
- B
Warm Standby
- C
Backup and Restore
- D
Multi-Region Active-Active
Show answer and explanation
Correct answer: B
Explanation
Warm Standby is the most appropriate DR strategy for the scenario because it strikes a balance between minimizing downtime and optimizing costs. By maintaining a scaled-down version of the production environment in the DR region, the company can achieve faster recovery times compared to Pilot Light or Backup and Restore, while avoiding the high costs associated with Multi-Region Active-Active.
- A. Incorrect.
Pilot Light is a cost-effective DR strategy where only the critical core components of the application are running in the DR region. However, it involves more downtime than Warm Standby, as additional infrastructure needs to be scaled up during a disaster.
- B. Correct.
Warm Standby maintains a scaled-down version of the production environment in the DR region, allowing for faster recovery while optimizing costs by not running a fully active setup. This meets the company's need for minimal downtime and cost efficiency.
- C. Incorrect.
Backup and Restore is the most cost-efficient option, as it involves storing backups and restoring them during a disaster. However, it has the longest recovery time and does not meet the requirement for minimal downtime.
- D. Incorrect.
Multi-Region Active-Active involves running fully duplicated production environments across multiple regions, ensuring zero downtime. However, it is the most expensive option and does not align with the company's cost optimization goal.
