SAA-C03 Question 184
Single answerA gaming company needs to implement a disaster recovery strategy for their multiplayer game platform hosted in AWS. The platform experiences consistent global traffic and requires minimal downtime in case of a regional failure. The company has a strict Recovery Time Objective (RTO) of under 5 minutes and a Recovery Point Objective (RPO) of under 1 minute. Which disaster recovery strategy best meets these requirements?
- A
Backup and Restore
- B
Pilot Light
- C
Warm Standby
- D
Active-Active Failover
Show answer and explanation
Correct answer: D
Explanation
Active-Active Failover is the most appropriate disaster recovery strategy for scenarios requiring extremely low RTO and RPO values. By maintaining fully operational environments in multiple regions, the system can instantly route traffic to another region in case of a failure, ensuring minimal downtime and data loss. Other strategies like Backup and Restore, Pilot Light, and Warm Standby involve delays in scaling or restoring, making them unsuitable for such strict requirements.
- A. Incorrect.
Backup and Restore is not suitable for the strict RTO and RPO requirements, as restoring systems and data from backups can take significant time, exceeding both the 5-minute RTO and 1-minute RPO.
- B. Incorrect.
Pilot Light involves keeping critical systems running at minimal capacity, but scaling up to full capacity may take more than 5 minutes, failing to meet the RTO requirement.
- C. Incorrect.
Warm Standby involves running a scaled-down version of the full environment, which can be scaled up more quickly than Pilot Light but may still exceed the strict RTO of under 5 minutes.
- D. Correct.
Active-Active Failover is the best fit for this scenario as it keeps multiple regions fully operational, enabling immediate failover with minimal downtime and data loss, meeting both the RTO and RPO requirements.
