NetworkPolicy From Memory. No Mistakes.

Tue, 31 Mar 2026 22:08:02 -0400

Cert exam incoming. Been drilling hard — writing YAML from scratch, no peeking at docs.

Today I wrote all the NetworkPolicy patterns from memory. No mistakes. 🥹

NetworkPolicy is the one topic everyone says trips them up — the ingress/egress selector logic, podSelector scoping, default deny patterns. It clicked. Apparently all this hardcore study is sinking in way more than I thought.

That’s the difference between “I think I’m ready” and “I know I’m ready.” Sure, you can look things up on the exam — but why burn time when you already know exactly what resource you need and where every field goes?
