Do you provide official certifications?
No, and nobody can sell you one but the body that issues it. SahabLabs sells PRACTICE: mock exams built to the same domain weights, duration and pass mark as the real paper, graded against real system state. Finish one and you earn a SahabLabs Certificate of Completion, which records what you did here. It is not a CKA, a CKAD or any other credential, and it is not recognised by the CNCF or the Linux Foundation — you still sit the real exam with them.
How does the 67% discount work?
A hands-on certification lists at $30 and is on launch sale at $10. Nothing to enter: the price is applied on the server when you check out, so what Stripe charges is the discounted figure whatever the page in front of you says.
Do I get a certificate?
Yes — a SahabLabs Certificate of Completion, issued when you pass one of our practice exams, with a verifiable link. It shows the exam, the score and the date. It is evidence of practice, not an official credential.
Is there a subscription?
No. One payment per certification, and it opens that certification's hands-on exams for 365 days with unlimited retakes — the sandbox is rebuilt from scratch every attempt. Nothing renews and there is nothing to cancel.
What is free, exactly?
Every theory-only (written) certification paper, every incident lab and every competitive race, with no card. Free is decided by what a paper IS rather than by a price on it, so a written exam cannot quietly end up behind a paywall.
Is there a free way to try a hands-on exam first?
Yes. Every hands-on exam has one free readiness check: a sample of its real tasks, graded on cluster state and reported per domain, so you find out where you are weak before you pay for anything.
