You do not need a paid Cloud Academy account to take this Lab Challenge.
This Lab Challenge will push you to the next level. It is an advanced-level environment where full and complete instructions are not included. This means you will have to demonstrate your problem-solving skills on AWS. You can check the status of your work by running checks that inspect the state of your Lab environment.
In case you need guidance before attempting the real challenge, you can find the link to a guided version of the Lab at the bottom of the Lab Challenge page.
