1. A. Setup IAM groups for each department and track their usage
2. B. Create separate accounts for each department, but use consolidated billing for payment and tracking
3. C. Create separate accounts for each department and track them separately
4. D. Setup IAM users for each department and track their usage

A user has created a blank EBS volume in the US-East-1 region. The user is unable to attach the volume to a running instance in the same region. What could be the possible reason for this?

1. A. The instance must be in a running stat
2. B. It is required to stop the instance to attach volume
3. C. The AZ for the instance and volume are different
4. D. The instance is from an instance store backed AMI
5. E. The instance has enabled the volume attach protection

An EBS volume provides persistent data storage. The user can attach a volume to any instance provided they are both in the same AZ. Even if they are in the same region but in a different AZ, it will not be able to attach the volume to that instance.

An orgAMzation has 10000 employees. The orgAMzation wants to give restricted AWS access to each employee. How can the orgAMzation achieve this?

1. A. Create an IAM user for each employee and make them a part of the group
2. B. It is not recommended to support 10000 users with IAM
3. C. Use STS and create the users’ run time
4. D. Use Identity federation with SSO

Correct Answer: D
Identity federation enables users from an existing directory to access resources within your AWS account,
making it easier to manage your users by maintaining their identities in a single place. In this case, the federated user is the only solution since AWS does not allow creating more than 5000 IAM users. Reference: http://docs.aws.amazon.com/IAM/latest/UserGuide/LimitationsOnEntities.html
