E.
Amazon EC2 resource
Answers
E.
Amazon EC2 resource
Suggested answer: A, B

Explanation:

This JSON text is an identity-based policy that grants specific permissions. The IAM principals that the solutions architect can attach this policy to are Role and Group. This is because the policy is written in JSON and is an identity-based policy, which can be attached to IAM principals such as users, groups, and roles.Identity-based policies are permissions policies that you attach to IAM identities (users, groups, or roles) and explicitly state what that identity is allowed (or denied) to do1.Identity-based policies are different from resource-based policies, which define the permissions around the specific resource1.Resource-based policies are attached to a resource, such as an Amazon S3 bucket or an Amazon EC2 instance1.Resource-based policies can also specify a principal, which is the entity that is allowed or denied access to the resource1.Organization is not an IAM principal, but a feature of AWS Organizations that allows you to manage multiple AWS accounts centrally2.Amazon ECS resource and Amazon EC2 resource are not IAM principals, but AWS resources that can have resource-based policies attached to them34.
