Question 5

A developer has created an AWS Lambda function that is written in Python. The Lambda function reads data from objects in Amazon S3 and writes data to an Amazon DynamoDB table. The function is successfully invoked from an S3 event notification when an object is created. However, the function fails when it attempts to write to the DynamoDB table.

What is the MOST likely cause of this issue?

    Correct Answer: C

    The most likely cause of the issue is that the Lambda function does not have IAM permissions to write to DynamoDB. When AWS Lambda functions interact with other AWS services, appropriate IAM permissions are required. If the Lambda function is able to read from S3 but fails when writing to DynamoDB, it indicates that the function's IAM role may lack the necessary permissions for DynamoDB write operations.

It is clearly something about permissions. So not A or B. Lambda functions can run in multiple Availability Zones (AZs) to ensure high availability and resilience. So it is not D.

Does anyone know how the correct answer is determined? Option C is the most voted and correct according to https://www.examtopics.com/discussions/amazon/view/88237-exam-aws-certified-developer-associate-topic-1-question-164/

C is correct because the question does not contain any details about the placement of the resources in different availability zones hence making it obvious for users to assume they al are running in the same region and that's the reason why it makes sense that the Lambda execution role does not have the write permission for dynomodb table.
