AWS Certified Solutions Architect – Associate (SAA-C02) — Question 66

A company has been storing analytics data in an Amazon RDS instance for the past few years. The company asked a solutions architect to find a solution that allows users to access this data using an API. The expectation is that the application will experience periods of inactivity but could receive bursts of traffic within seconds.
Which solution should the solutions architect suggest?

Answer options

• A. Set up an Amazon API Gateway and use Amazon ECS.
• B. Set up an Amazon API Gateway and use AWS Elastic Beanstalk.
• C. Set up an Amazon API Gateway and use AWS Lambda functions.
• D. Set up an Amazon API Gateway and use Amazon EC2 with Auto Scaling.

Correct answer: C

Explanation

The correct option is C because AWS Lambda functions can automatically scale to handle sudden bursts of traffic without the need for pre-provisioning resources. The other options involve services that require more management and scaling configurations, which may not efficiently handle the application's bursty traffic pattern.
