You have an application to be setup in AWS, and the following points are to be considered:
a) A Web tier hosted on EC2 Instances
b) Session data to be written to DynamoDB
c) Log files to be written to Microsoft SQL Server
How will you ensure that the application writes data to a DynamoDB table?
A. Add an IAM user to a running EC2 instance.
B. Add an IAM user that allows write access to the DynamoDB table.
C. Create an IAM role that allows read access to the DynamoDB table.
D. Create an IAM role that allows write access to the DynamoDB table.
Explanation:
Answer – D
IAM roles are designed so that your applications can securely make API requests from your instances, without requiring you to manage the security credentials that the applications use. Instead of creating and distributing your AWS credentials, wean delegate permission to make API requests using IAM roles.
