You are building up a Lambda function that runs periodically and processes the data stored in a DynamoDB table. As the data in the DynamoDB table grows fast, you need to estimate the cost of the Lambda function. Which of the following factors directly determine the monthly cost of Lambda? (Select TWO.)

Answer options:

A.The programming language used by the Lambda function.
B.The Lambda function handler.
C.The memory allocated to the Lambda function.
D.The timeout value of the Lambda function.
E.The total number of requests for the Lambda function.

Correct Answer – C, E
Option A is incorrect: Because users are charged based on the number of requests and the time it takes for the code to execute. The programming language does not directly determine the cost.
Option B is incorrect: Because the Lambda function handler does not impact the monthly cost at all.
Option C is CORRECT: Because the duration price depends on the amount of memory allocated to the function.
Option D is incorrect: Because the timeout value is not a direct factor in calculating the price. Please check the below reference for details.
Option E is CORRECT: Because the Lambda function charges you based on the number of requests, such as $0.20 per 1M requests.
