Ultimate access to all questions.
An IT company operates a web application hosted on Amazon EC2 instances. The application requires read-only access to an Amazon DynamoDB table to retrieve data.
As a Developer Associate, what is the best-practice solution you would recommend to achieve this requirement?
A
Run application code with AWS account root user credentials to ensure full access to all AWS services
B
Create an IAM role with an AmazonDynamoDBReadOnlyAccess policy and apply it to the EC2 instance profile
C
Create an IAM user with Administrator access and configure AWS credentials for this user on the given EC2 instance
D
Create a new IAM user with access keys. Attach an inline policy to the IAM user with read-only access to DynamoDB. Place the keys in the code. For security, redeploy the code whenever the keys rotate
