SAP-C02 Question 204
Single answerYour company operates a critical e-commerce platform hosted on AWS. To ensure high availability and quick recovery in the event of a regional disaster, you are tasked with designing a disaster recovery strategy that minimizes downtime and data loss while keeping costs under control. The platform uses multiple EC2 instances, an RDS database, and an S3 bucket to store static assets. Which disaster recovery strategy would be MOST suitable for this requirement?
- A
Backup and Restore
- B
Pilot Light
- C
Warm Standby
- D
Multi-Site
Show answer and explanation
Correct answer: C
Explanation
Warm Standby is the best fit for this scenario because it balances the need for quick recovery and minimized downtime with cost considerations. It ensures that a scaled-down version of the production environment is always running in a secondary region, allowing for faster recovery than Backup and Restore or Pilot Light without the high costs associated with Multi-Site.
- A. Incorrect.
Backup and Restore is the least expensive option but involves the longest recovery time. In this scenario, minimizing downtime is critical, so this is not the best choice.
- B. Incorrect.
Pilot Light provides a minimal version of the environment in the secondary region, but scaling up from the pilot light to full production takes additional time. While it reduces costs compared to Warm Standby, it doesn't meet the requirement for quick recovery.
- C. Correct.
Warm Standby keeps a scaled-down version of the production environment running in the secondary region. This approach balances cost and recovery time, making it the most suitable choice for minimizing downtime and data loss.
- D. Incorrect.
Multi-Site involves running fully redundant environments in multiple regions simultaneously. While it provides the fastest recovery time, it is also the most expensive option and is unnecessary for the cost-controlled scenario described.
