The Cloud Practitioner exam is often described as the easy one. That framing is unhelpful. It is a broad exam rather than a deep one, and breadth is its own kind of difficulty when the service catalogue keeps growing.
The four domains
CLF-C02 splits into cloud concepts, security and compliance, cloud technology and services, and billing. The weighting matters more than the names: roughly half the exam sits in the services domain, so time spent memorising the pricing calculator UI is time badly spent.
How the questions read
Associate-level questions describe a scenario and ask you to pick an architecture. Practitioner questions usually describe an outcome and ask which service produces it. The distinction sounds small and changes how you study: you need recall of what each service is for, not how to configure it.
What to read first
Start with the shared responsibility model. Almost every security question resolves to a single judgement about which side of the line a task falls on, and getting that instinct early makes the rest of the security domain cheap.
Notes on this series
Each part stands alone. They are numbered because the concepts compound, not because you have to read them in order.
