Which Kubernetes component stores the state of the cluster?

Correct
etcd is the consistent key-value store that holds all cluster data. Only the API server talks to it directly.
How does GoldenKube practice work?
You choose a certification and GoldenKube serves one question at a time. As soon as you answer, you see the verdict and an explanation of why the correct option is right and why the others are not. Questions you miss return after a few other answers, then again after a day and after a few days, until you answer them correctly. The domains where you are weakest come first, so your time goes where it helps most. Reloading the page keeps the verdict on screen, and your progress is broken down by certification and domain so you can see what is mastered and what is not.
1. Pick a certification
Choose the exam you are preparing for. Each one follows its official domains.
2. Answer and learn immediately
Get the verdict and an explanation as soon as you answer, while the question is still fresh.
3. Weak areas come back
Questions you miss return until you answer them correctly, and the domains you are weakest in come first.
Which certification practice exams are available?
Practice is available today for KCNA, KCSA, PCA, CCA, CAPA, CGOA, CBA, OTCA, KCA. Each has its own page with the official exam format, the domains and their weights, and a way to start practising. These are multiple-choice exams. Performance-based exams such as CKA, CKAD and CKS need a terminal, so hands-on labs are planned rather than faked with quiz questions, and the remaining question banks are on the way. Every certification in the program has a page that states exactly what GoldenKube covers for it today, so you never have to guess whether a bank exists before you click.

What is the Golden Kubestronaut program?
Golden Kubestronaut is the Cloud Native Computing Foundation recognition for people who hold all 16 certifications in the program: the five Kubestronaut exams plus the additional Golden tier. GoldenKube follows that journey one certification at a time, with a page for each exam and a program page that explains the order, the cost and the prerequisites. The program page reads its figures from the official certification pages and shows the date they were last checked, so you can plan a realistic path before you spend anything.

Where can I read before I practise?
The guides explain how the exams differ and how to plan your preparation: a roadmap across all sixteen certifications, a comparison of multiple-choice and hands-on exams, a look at free versus paid practice, and an explanation of the spaced repetition schedule GoldenKube uses. Each guide names the official pages its facts come from and the date they were checked. They are written to help you decide what to study next, not to replace the official exam pages, which remain the authority on prices, rules and policies.

Learn the concepts. Not leaked answers.
GoldenKube is for understanding Kubernetes and the Cloud Native stack well enough to pass on your own. There are no exam dumps here: every question comes with an explanation of why the answer is right and why the others are not.
Frequently asked questions
Is GoldenKube free?
Yes, completely. Answer your first 10 questions as a guest with no signup. After that a free account is required to continue; there is no paid tier and no credit card.
Is GoldenKube official?
No. GoldenKube is an independent community learning project. It is not affiliated with, endorsed by, or sponsored by CNCF or The Linux Foundation.
Are these real exam questions?
No. GoldenKube does not publish or collect real exam questions or brain dumps. The questions are practice material meant to teach the concepts each exam covers.
How does adaptive practice work?
Questions that are due for review come first, then the domains where you have answered the fewest questions correctly. A question you miss comes back after you answer a few others, then again after a day and after a few days, until you get it right and it counts as mastered.
Which certifications are supported?
Practice is available for KCNA, KCSA, PCA, CCA, CAPA, CGOA, CBA, OTCA, KCA. Performance-based exams (such as CKA, CKAD and CKS) need a terminal, so labs are planned; the remaining question banks are on the way. Every certification in the program has its own page with its status.
Do I need an account?
Not to start. You can answer your first 10 questions as a guest, and your progress is tied to this browser through an anonymous cookie. After the tenth answer a free account is needed to continue; what you did as a guest is carried over into it.
