SAA-C03 Question 210
Select 3You are designing a disaster recovery (DR) architecture for a business-critical application. The application is deployed in a primary AWS Region and has a standby environment in a secondary Region. During DR drills, you notice that the standby environment fails to scale appropriately because of service quota limits in the secondary Region. How can you ensure the standby environment can handle production workloads during a failover while adhering to AWS best practices?
- A
Request quota increases in the secondary Region for the required services and resources to match the primary Region's quotas.
- B
Use AWS Service Quotas to monitor and adjust quotas in the secondary Region proactively.
- C
Configure Auto Scaling groups in the standby environment to automatically request quota increases during failover.
- D
Deploy service resources in the secondary Region with quotas already scaled to match expected failover demand.
- E
Enable AWS Trusted Advisor to automatically increase service quotas in the secondary Region during failover.
Show answer and explanation
Correct answers: A, B, D
Explanation
To ensure the standby environment can handle production workloads during failover, you must proactively manage service quotas in the secondary Region. This includes requesting quota increases, monitoring quotas using AWS Service Quotas, and pre-deploying resources with sufficient quotas. Auto Scaling groups and AWS Trusted Advisor cannot automatically adjust quotas, so they are not viable options in this scenario.
- A. Correct.
Correct: Requesting quota increases in the secondary Region ensures that resources are available to handle production workloads during failover.
- B. Correct.
Correct: AWS Service Quotas allows you to monitor and manage quotas, helping you proactively adjust them before a failover scenario.
- C. Incorrect.
Incorrect: Auto Scaling groups cannot automatically request quota increases. Quota increases must be requested manually or programmatically via AWS APIs.
- D. Correct.
Correct: Pre-deploying resources with appropriate quotas in the secondary Region ensures readiness for failover without delays.
- E. Incorrect.
Incorrect: AWS Trusted Advisor provides recommendations but does not automatically increase service quotas. Quota increases require manual or programmatic action.
