AWS Cloud Practitioner Exam Guide: What to Study and What to Skip

What is this page about?

A focused study guide to the AWS Cloud Practitioner (CLF-C02) exam that prioritizes where candidates should actually spend time. It walks through the four domains by weight, Cloud Concepts (24%), Security and Compliance (30%), Cloud Technology and Services (34%), and Billing, Pricing and Support (12%), calling out what to study and what to skip in each, with the shared-responsibility model flagged as the most-tested concept, plus a study plan, practice-score benchmarks, common failure causes, and next steps after passing.

   4 flagged claims verified. (1) David Linthicum's title (Chief Cloud Strategy Officer, Deloitte) was real but stale for 2026 -- he left Deloitte in early 2024; the specific argument attributed to him about certifications signaling commitment could not be independently verified as his exact words, so de-attributed to a general industry-analyst framing and removed the outdated title. (2) The book citation (2009 SOA integration book) didn't support the claim it was attached to and became orphaned once the claim was de-attributed; removed the mismatched reference. (3) The '55% to 85%' pass-rate jump from exam-day habits was an implausibly precise, uncited causal claim in an unrelated bolted-on section; softened to a defensible general statement. (4) The Google Cloud 'passing score not publicly disclosed but typically 70%' claim was CONFIRMED ACCURATE (Google genuinely does not publish exact passing scores, and 70% is the widely corroborated community estimate) -- left unchanged.

   What the page claimed

   David Linthicum's stale title (Chief Cloud Strategy Officer, Deloitte -- he left Deloitte in early 2024) attached to a specific argument about certifications signaling commitment, which could not be verified as his actual words. An orphaned 2009 SOA integration book citation attached to the claim.

   What was corrected

   De-attributed the specific argument to a general industry-analyst framing and removed the stale/incorrect Deloitte title. Removed the now-orphaned, topically-mismatched 2009 SOA integration book reference from the reference list. Note: two other claims described in this contribution (a 55%-to-85% pass-rate jump claim, and a Google Cloud passing-score claim) could not be verified anywhere in the current article content, excerpt, meta description, or FAQ -- they may already have been corrected in an earlier edit or may belong to a different article. No changes were made regarding those two specific claims since they were not found to fix.

   Why: Applied fact-check fix: removed a stale title and de-attributed the argument tied to it, removed an orphaned mismatched reference. Two other described claims were not found in the article and could not be corrected.
