Questions about this lab
Do I need my own AWS account?
No. When you start the lab, Cloud Arena gives you a real, temporary AWS account with its own login, locked to one region. You work in the real AWS Management Console, not a simulator.
Will AWS charge me anything?
No. Cloud Arena pays for the AWS resources, and everything you create is deleted automatically when you stop the lab or the session ends. Nothing is billed to you by AWS.
How long does the KMS-Encrypted App Stack: EBS + S3 with Key Policies lab take?
Plan for about 120 minutes. The session timer is shown on screen, and every task is checked against your live AWS account when you click Verify.
