Self-Check
A 98-question bank spanning every domain in this course — cluster architecture, workloads, networking, storage, troubleshooting, RBAC, supply-chain security, and the CNCF landscape — served here with no clock and no stakes. Pick a domain, take a quick ten, and answer cold: each question is graded the moment you click, and the explanation underneath says why the right option is right, and why the plausible-looking wrong one isn't. Options reshuffle on every pass so you're recalling the answer rather than its position, and your results are saved on this device, so Past misses is always a real list of what you actually got wrong. The mock exams under each certification are the timed, performance-based dress rehearsal on a real cluster; this page is the daily drill that gets you ready to sit one.
Reading a page again feels like studying, because the words look familiar the second time. But recognizing a sentence and being able to produce the answer with the page closed are two different skills — and only the second one is any use when a Pod is stuck CrashLoopBackOff and nobody's opened the manual. So close the page and try to answer first. Getting one wrong here is a good day: it costs nothing, and it hands you the exact topic to go re-read.
Foxy: I've read the RBAC page four times now. I'm good.
Remy: Then say it now, page closed: what's the difference between a Role and a ClusterRole, and when does a RoleBinding still reference the latter?
Foxy: It's... namespaced versus cluster-scoped, and a RoleBinding can reference a ClusterRole to reuse its rules inside just one — okay, I actually had that.
Professor Owl: That hesitation before the answer landed is worth noticing, Foxy. Recognizing a paragraph isn't the same skill as producing the answer under a clock, and only one of the two survives contact with a real exam task.
Timmy the Turtle: Same rule as admission control, then. Don't let something through on "it looked familiar" — answer ten cold, read what you missed, run the misses again.
The chip on each question names its domain, and the animal on that chip is the same host who teaches it in the lesson — the Pod Squad roster in miniature. Filter to one domain and clear it at 70% or better to earn that character's 🏅 badge. When a miss is a vocabulary problem rather than a concept problem, the Glossary and the Flashcards are the faster fix; when you want a full timed paper on a real cluster instead, go sit one of the certification mock exams.
