Answer: View the AWS Billing console

## Explanation IAM users can **view the AWS Billing console** without requiring root user credentials. However, they cannot perform the following actions without root user access: - **Change to a different AWS Support plan** - This requires root user permissions - **Close an AWS account** - This can only be done by the root user - **Activate access to the AWS Billing console** - This requires root user permissions to grant IAM users billing access IAM users can view billing information if they have been granted the necessary IAM permissions (such as `aws-portal:ViewBilling`), but they cannot enable or disable billing access for themselves or others - that requires root user credentials.
