Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 5 discussion

Exam question from Amazon's AWS Certified Developer - Associate DVA-C02
Question #: 5
Topic #: 1
[All AWS Certified Developer - Associate DVA-C02 Questions]

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?

  • A. The Lambda function's concurrency limit has been exceeded.
  • B. DynamoDB table requires a global secondary index (GSI) to support writes.
  • C. The Lambda function does not have IAM permissions to write to DynamoDB.
  • D. The DynamoDB table is not running in the same Availability Zone as the Lambda function.

Selected Answer: C
keywords: - fails when it attempts to write => discard A (when invoke success, not due to rate limit) Knowlege: - GSI relevant to read action, not write => discard B - DynamoDB is global server, so AZ is not effect on it => discard D

Create an IAM policy that grants your Lambda function read and write permissions to a specific DynamoDB table by defining the actions dynamodb:GetItem, dynamodb:PutItem, and others as needed

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.
