What’s on the CompTIA Data+ cheat sheet
- Data Concepts & Environments (20%) — structured vs. unstructured data, measurement scales, OLTP vs. OLAP, warehouses, lakes, and the big-data V's.
- Data Acquisition & Preparation (22%) — ETL vs. ELT, sampling, data cleansing (missing values, duplicates, outliers), and the four data-mining techniques.
- Data Analysis (24%) — descriptive statistics, correlation vs. causation, hypothesis testing, and the four types of analytics — the heaviest domain.
- Visualization & Reporting (20%) — matching charts to goals, dashboards and KPIs, and avoiding misleading visuals like truncated axes.
- Data Governance, Quality & Controls (14%) — governance roles, master data, quality dimensions, PII, masking, and privacy regulations.
How to use it in your final week
- Lead with Data Analysis (24%): rehearse mean vs. median vs. mode, standard deviation, and the correlation-is-not-causation trap until they're reflexive — this is your single biggest score-mover.
- Memorize the chart-to-goal map from the sheet: compare → bar, over time → line, relationship → scatter, distribution → histogram or box plot, parts of a whole → pie.
- Lock the environment distinctions: warehouse is schema-on-write, lake is schema-on-read, ETL transforms before loading, ELT after — a few of these questions are nearly free points.
- Read the sheet the morning of the exam for a final pass on governance regs (GDPR, HIPAA, PCI-DSS, CCPA) and quality dimensions, then walk in and treat the 90-minute clock as routine.
The cheat sheet is your review layer — your CompTIA Data+ practice test drives the exam-readiness ring at the top of this page. Download it, review, then take a full practice exam (or drill with the study guide and flashcards) to see where you stand.
CompTIA Data+ cheat sheet FAQ
Yes — download the CompTIA Data+ cheat sheet as a PDF with no sign-up and no account. It sits alongside Career Employer's free Data+ practice test, study guide, and flashcards, so you can cram the facts and then test yourself in one place.
It does. The sheet is built to DA0-002 (V2), which launched October 14, 2025 and replaced DA0-001 (V1, retired in English on April 14, 2026). That means the domain names and weights, the cloud and AI content, and the governance topics all match the exam you'll actually sit in 2026.
Skim it front to back once to see the whole blueprint, then park on the two heaviest domains — Data Analysis (24%) and Data Acquisition & Preparation (22%). Together they're nearly half your score, so drilling those facts moves the needle the most in your final days.
No — the sheet is a condensed review layer, not a full course. You need a scaled score of 675 on the 100-900 scale, and the performance-based questions reward applied skill you build with practice, not memorization. Use the sheet to lock in vocabulary and formulas, then rehearse with the free practice test.
