AWS Cloud Practitioner (CLF-C02) trap evaluation

Where correct knowledge still produces wrong answers

Many missed points on CLF-C02 come from treating similar-seeming things as interchangeable. AWS has multiple services that move data, multiple that run compute, and multiple that handle backups; the exam regularly places two or three as answer choices for the same scenario. Candidates who understand what each service does in isolation still pick the wrong one when similar names or functions appear together. The shared responsibility boundary creates a parallel problem: the line between what AWS manages and what the customer manages shifts by service model, and a correctly memorized rule still fails when applied to the wrong layer on a managed service. Pricing and support tiers work the same way. Reserved Instances, Savings Plans, and on-demand each serve distinct workload types, and support plans have specific coverage the exam tests precisely. These categories remain distinct on the exam even when they feel interchangeable in study.
