How to Pass the KCNA Exam

KCNA-specific tips and the most common pitfalls.

KCNA exam tips

• Distractors often swap similar components (etcd vs API server, kubelet vs kube-proxy). Know each component's exact role cold.
• CNCF landscape questions test category recognition (monitoring, service mesh, storage, security) — not implementation depth.

Common KCNA pitfalls

• Understudying the CNCF landscape: it's a smaller section but questions appear consistently. Know the major projects by category.
• Confusing etcd with the API server: etcd stores cluster state; the API server is the gateway. A very common wrong-answer trap.
