Why hands-on

Certifications that test what you can do, not just what you remember

Many IT exams are multiple choice. The professional-level exams from The Linux Foundation are performance-based: a live environment, a list of real-world tasks and a clock. The format is built to show practical skills, and preparing for it mirrors day-to-day work.

Performance-based

You configure, deploy, secure and troubleshoot in a real command-line environment. There is no guessing between four answers: the work either runs or it does not.

Vendor-neutral

Skills that travel across clouds and Linux distributions. The Kubernetes exams are developed together with the Cloud Native Computing Foundation® (CNCF®), the home of the Kubernetes project.

Verifiable

Pass and you receive a PDF certificate plus a digital badge that employers can verify online. Every certification compared on this page stays valid for 2 years.

76%

of hiring managers consider certifications important for evaluating a candidate's technical skills.

Study plan

A 4-step plan to walk in ready

The same approach works for every exam on this page: learn it, lab it, rehearse it, book it.

  1. 01

    Start free

    Build fundamentals with free, self-paced courses such as Introduction to Linux (LFS101, about 60 hours), Introduction to Kubernetes (LFS158, 15–20 hours) or Introduction to DevOps and Site Reliability Engineering (LFS162, 10–12 hours). Each includes 90 days of access and a digital badge.

  2. 02

    Lab it

    Take the course mapped to your exam: LFS207 for the LFCS, LFS258 for the CKA, LFD259 for the CKAD or LFS260 for the CKS. Each lists at $299 with 12 months of access and hands-on labs.

  3. 03

    Rehearse it

    Hands-on exams come with two exam-simulator sessions from Killer.sh, with 36 hours of access each for the CKA, CKAD, CKS and LFCS. Run them like the real thing: timer on, no shortcuts.

  4. 04

    Book it

    You have 12 months from purchase to schedule and take the exam. A retake is included, and a pass earns a PDF certificate and a verifiable digital badge, valid for 2 years.

Exam-day tips for the hands-on exams

  • Run the system check and prepare your ID and a clear desk well before exam day.
  • Get fast with imperative commands: kubectl create deployment … --dry-run=client -o yaml beats typing YAML from scratch.
  • Practice in vim or nano until editing YAML and config files feels automatic.
  • Read each task twice and confirm which cluster or host it targets before you start.
  • Skip anything that stalls you and come back later. Bank the points you know first.
  • Verify every task with get, describe or curl before moving on.
  • Practice on the Kubernetes release the exam uses; the official exam page lists the current version.
  • Read the candidate handbook for allowed resources and exam rules.
