🚀 CKA Exam Overview: What Every Kubernetes Engineer Should Know Before Starting
If you're working in DevOps, Cloud Engineering, Platform Engineering, or SRE, chances are you've heard about the Certified Kubernetes Administrator (CKA) certification.
But here's what surprises most people:
⚠️ There are no multiple-choice questions.
You get a real Kubernetes environment and must perform actual administrative tasks within a limited time.
That makes the CKA one of the most practical certifications in the cloud-native ecosystem.
