Amazon Exam SAP-C02 Topic 3 Question 51 Discussion

Actual exam question for Amazon's SAP-C02 exam

Question #: 51
Topic #: 3

A company is running a serverless ecommerce application on AWS. The application uses Amazon API Gateway to invoke AWS Lambda Java functions. The Lambda functions connect to an Amazon RDS for MySQL database to store data.

During a recent sale event, a sudden increase in web traffic resulted in poor API performance and database connection failures. The company needs to implement a solution to minimize the latency for the Lambda functions and to support bursts in traffic.

Which solution will meet these requirements with the LEAST amount of change to the application?

AUpdate the code of the Lambda functions so that the Lambda functions open the database connection outside of the function handler. Increase the provisioned concurrency for the Lambda functions.

BCreate an RDS Proxy endpoint for the database. Store database secrets in AWS Secrets Manager. Set up the required 1AM permissions. Update the Lambda functions to connect to the RDS Proxy endpoint. Increase the provisioned concurrency for the Lambda functions.

CCreate a custom parameter group. Increase the value of the max_connections parameter. Associate the custom parameter group with the RDS DB instance and schedule a reboot. Increase the reserved concurrency for the Lambda functions.

DCreate an RDS Proxy endpoint for the database. Store database secrets in AWS Secrets Manager. Set up the required 1AM permissions. Update the Lambda functions to connect to the RDS Proxy endpoint. Increase the reserved concurrency for the Lambda functions.

Gotta love those sudden 'sale events' that bring down the whole system. Wish I could get a bonus for that kind of performance.

Haha, 'reserved concurrency' for Lambda? Sounds like a fancy way of saying 'put a cap on it'.

Hold up, why not just increase the max_connections on the RDS instance? Seems like a quick fix to me.

Hmm, I see your point. Maybe we should consider all the options before making a decision.
