The Linux Foundation worked with industry experts and the Linux kernel community to identify the core domains and the critical skills, knowledge and competencies applicable to each certification. Performance-based exams were then developed based on the competencies that were identified.
Exam Details & Resources
This exam is an online, proctored, performance-based test that requires implementing multiple solutions within a Remote Desktop Linux environment. Visual Studio Code, Vim and Webstorm (kindly sponsored by JetBrains) are included as editors in this environment.

The exam includes tasks simulating on-the-job scenarios, and Candidates have 2 hours to complete the tasks.

There are no pre-requisites for this exam.
Lab Info

Lab exercises in this course are designed to work either on native hardware, or using a virtual machine (VM), under a hypervisor, such as those in the KVM, VMWare, or Virtual Box families. Detailed instructions to set up your lab environment are provided in the course.

If using a cloud provider like GCP or AWS, you should be able to complete the lab exercises using the free tier or credits provided to you. However, you may incur charges if you exceed the credits initially allocated by the cloud provider, or if the cloud provider’s terms and conditions change.
