Before you start

How the lab works

  1. Get a real, temporary AWS account locked to one region. No AWS account of your own needed.
  2. Build in the real AWS console with a guide beside it, and hints when you are stuck.
  3. Verify every task: we check the resources in your live account.
  4. Automatic cleanup: everything is deleted when you stop, and nothing is billed to you.

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 IAM Instance Role: Least-Privilege S3 Access from EC2 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.

How do I get access to this lab?

It is included in the AWS Certified Solutions Architect – Associate plan: a one-time payment for every lab in the path, 2 attempts per lab and a 7-day money-back guarantee. You can also start with the 5 free labs.

Does this lab help with the Solutions Architect – Associate (SAA-C03) exam?
