Learn Labs
Labs are hands-on learning experiences that allow you to practice your skills in a real-world environment. While all LabEx content is referred to as “Labs,” there are actually two distinct types:
When you start a lab, LabEx will automatically create a new Virtual Machine (VM) for you. You can follow the instructions in the lab to practice in the VM.
- Guided Lab (beaker icon): Ideal for beginners, these labs focus on conceptual explanations and step-by-step guidance. Users can complete the practice by following along with each instruction.
-
Challenge Lab (PASS icon): Designed for testing and challenging advanced users, these labs typically contain minimal explanatory content. They provide only objectives and requirements, requiring users to independently attempt and complete the challenges.
