How to Pass AZ-400 — and Actually Land the DevOps Role

By Victor Ola T (Captain O)

The exam that punishes cramming hardest — scenario-heavy, and it assumes you've built real pipelines. What it tests, why build-and-release pipelines are roughly half the marks, a study plan built on one real pipeline, and why the badge only lands the job when a pipeline sits behind it.
