Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 218 discussion

Exam question from Amazon's AWS Certified Developer - Associate DVA-C02
Question #: 218
Topic #: 1
[All AWS Certified Developer - Associate DVA-C02 Questions]

A company requires that all applications running on Amazon EC2 use IAM roles to gain access to AWS services. A developer is modifying an application that currently relies on IAM user access keys stored in environment variables to access Amazon DynamoDB tables using boto, the AWS SDK for Python.

The developer associated a role with the same permissions as the IAM user to the EC2 instance, then deleted the IAM user. When the application was restarted, the AWS AccessDeniedException messages started appearing in the application logs. The developer was able to use their personal account on the server to run DynamoDB API commands using the AWS CLI.

What is the MOST likely cause of the exception?

  • A. IAM policies might take a few minutes to propagate to resources.
  • B. Disabled environment variable credentials are still being used by the application.
  • C. The AWS SDK does not support credentials obtained using an instance role.
  • D. The instance’s security group does not allow access to http://169.254.169.254.
