SAP-C02 Question 505
Select 3An e-commerce company is setting up a new application in AWS that uses Amazon RDS, Amazon S3, and Application Load Balancers (ALBs). During testing, the application encounters errors due to reaching service limits. As a Solutions Architect, you need to ensure that the application scales smoothly. What steps should you take to address potential service quota issues proactively?
- A
Use Service Quotas to request quota increases for RDS, S3, and ALBs as needed.
- B
Enable Amazon CloudWatch to monitor service usage against quotas and set alarms for threshold breaches.
- C
Implement an Auto Scaling policy to automatically scale resources beyond service quotas when needed.
- D
Use AWS Trusted Advisor to identify and review service limits for your account.
- E
Create a custom CloudFormation template to override default service quotas for required resources.
Show answer and explanation
Correct answers: A, B, D
Explanation
Proactively managing service quotas is critical to ensuring application scalability and availability. Using Service Quotas, CloudWatch, and AWS Trusted Advisor allows you to monitor usage, identify limits, and request increases as necessary. Auto Scaling and CloudFormation do not bypass hard service limits and cannot be used for quota management.
- A. Correct.
Correct. Service Quotas provides a centralized console to view and request quota increases for AWS services, making it easier to proactively manage limits.
- B. Correct.
Correct. CloudWatch can monitor resource usage and alert you when you're nearing a quota limit, allowing you to take action before hitting a hard limit.
- C. Incorrect.
Incorrect. Auto Scaling adjusts resource capacity but cannot exceed service quotas. Limits still apply unless you request an increase.
- D. Correct.
Correct. AWS Trusted Advisor provides a Service Limits check to help identify resource limits that might affect your application.
- E. Incorrect.
Incorrect. CloudFormation cannot override or increase AWS service quotas. These must be managed using Service Quotas or through a manual request.
