AWS Certified Developer – Associate (DVA-C02) — Question 239

A company recently deployed an AWS Lambda function. A developer notices an increase in the function throttle metrics in Amazon CloudWatch.

What are the MOST operationally efficient solutions to reduce the function throttling? (Choose two.)

Answer options

• A. Migrate the function to Amazon Elastic Kubernetes Service (Amazon EKS).
• B. Increase the maximum age of events in Lambda.
• C. Increase the function’s reserved concurrency.
• D. Add the lambda:GetFunctionConcurrency action to the execution role.
• E. Request a service quota change for increased concurrency.

Correct answer: C, E

Explanation

Increasing the function's reserved concurrency (C) directly allocates more resources to handle incoming requests, reducing throttling. Requesting a service quota change for increased concurrency (E) allows for an even greater capacity if the current limits are being reached, thus improving performance. The other options do not effectively address the throttling issue in an operationally efficient manner.
