To provide more context around knowledge acquisition, we recently released validation for Hands-on Labs. These Hands-on Labs work by assessing your ability to execute and validate whether you have correctly completed the appropriate action or actions.
Skill Profiles are also affected by performance-based Hands-on Labs, you can attempt to complete exam-style Labs that provide only limited instructions. You will be briefed on the Lab scenario and left to your own devices to complete it. As of February 2019, we have one performance-based AWS Hands-on Lab.
