Self-Check
A 120-question bank spanning every domain in this course — the seven-station Mission Control curriculum (Foundations, GitOps, service mesh, policy as code, observability, the developer portal, Linux fundamentals) plus one domain for each of the nine project certifications — 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 certification mock exams under each cert are the timed, full-paper dress rehearsal; this page is the daily drill that gets you ready to sit one of the sixteen.
Reading a lesson 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 sync is stuck 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 policy-as-code page four times now. I'm good.
Remy: Then say it now, page closed: what's the difference between a Kyverno validate rule and a mutate rule, and what does audit mode change about either?
Foxy: It's... validate accepts or rejects, mutate rewrites the object before it's persisted, and audit mode just reports instead of blocking — 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 every station on this ladder. 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 staffs that console at Mission Control. 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 across everything instead, sit the Exam Simulator — or, for one specific credential, go sit one of the certification mock exams.
