CKS practice questions, dealt by the exam blueprint
Hands on a real cluster, at a command line, with the documentation open. So this drills typed kubectl, task chains graded on a simulated cluster, and a full mock under the same conditions.
flashkube is a flashcard game for Kubernetes certification. Miss a card and it comes back sooner; answer it well and it rests. That is spaced repetition, and it is the whole engine.

Which term does this describe? Binding a cloud IAM role to a Kubernetes ServiceAccount so Pods obtain cloud credentials through short-lived federated tokens instead of long-lived secret keys.

From today's CKS hand · 10 cards, dealt by the blueprint
How many CKS cards are there?
6 islands · 19 landings
174 cards written for CKS, across 6 islands and 19 landings — counted from the cartridge itself, not written into this sentence. Cards are tagged per exam, so this is what a CKS candidate actually gets, not the whole library.
What is on the CKS exam, and how much of each?
official blueprint weights
- Cluster Setup15%
- Cluster Hardening15%
- System Hardening10%
- Minimize Microservice Vulnerabilities20%
- Supply Chain Security20%
- Monitoring, Logging and Runtime Security20%
Your daily hand is sampled against these weights, so the domain worth a quarter of the exam gets a quarter of your practice.
How does the CKS exam run, and what does that change?
Hands on a real cluster, at a command line, with the documentation open.
So the cartridge drills typed commands and finding the answer in the documentation alongside the recall underneath them — the recognition that makes your lab hours count. And task chains: multi-step kubectl work graded on a simulated cluster by what it ends up holding, which is the exam's own rule.
Use a lab for the cluster. Use flashkube for everything you will forget between now and the exam — it is the other half of the same preparation, not a substitute for the first.
Do I need another certification before CKS?
You must pass CKA before you may sit this one. The same cartridge covers both: one payment opens every exam sea, so preparing for CKA first costs nothing extra.
What does CKS prep on flashkube cost?
$29, paid once. Nothing renews and nothing lapses — and every card written after you buy is already yours. Three islands of free water, from wherever you land, and ten CKS questions dealt by the blueprint free, with no account.
