Try these questions from our free Data Analytics Certifications (DAC) practice tests. The correct answer and an explanation follow each question.
A data analyst is publishing a report using a dataset that includes personally identifiable information (PII). Which technique best protects individual privacy while preserving data utility?
Answer: B. Anonymization or de-identification of the PII fields
Anonymization or de-identification removes or masks PII so individuals cannot be identified, allowing the data to be used analytically without exposing personal information.
What does a data catalog primarily provide in a data governance program?
Answer: B. A searchable inventory of data assets with metadata and lineage information
A data catalog is a metadata management tool that helps users find, understand, and trust data assets across the organization.
What is 'differential privacy' as used in data analytics?
Answer: B. A mathematical framework that adds statistical noise to datasets to protect individual privacy while allowing aggregate analysis
Differential privacy is a mathematical technique that injects carefully calibrated noise into query results so that individual data points cannot be identified, while still allowing meaningful aggregate statistics.
Which type of analytics predicts future trends based on historical data?
Answer: B. Predictive analytics.
Predictive analytics is a type of data analytics that uses historical data, statistical algorithms, and machine learning techniques to identify the likelihood of future outcomes or trends. It aims to forecast what might happen next, enabling proactive decision-making, risk assessment, and strategic planning based on anticipated events.

The number of questions varies significantly by certification. For example, the CompTIA Data+ (DA0-002, V2) exam features a maximum of 90 performance-based and multiple-choice questions with a 90-minute time limit and a passing score of 675 (on a 100-900 scale). In contrast, certifications like the Google Data Analytics Professional Certificate use a series of course quizzes and hands-on projects instead of a single proctored exam. Always consult the official 2026 exam blueprint for your specific Data Analytics Certification (DAC) to confirm the exact format and question count.
Most data analytics certification exams are considered challenging as they test practical skills in data mining, SQL, statistical analysis, and data visualization tools like Tableau or Power BI. The difficulty is subjective and depends on your hands-on experience. For 2026, candidates with a strong foundation in statistics and database querying will find the material more accessible. Consistent practice is crucial to mastering the complex, scenario-based questions.
To pass on your first attempt, focus on the official exam objectives. Master core concepts like data wrangling, ETL processes, and statistical modeling. Use high-quality practice tests to simulate the real exam environment and identify knowledge gaps. For your 2026 exam, prioritize hands-on projects using tools like Python or R. This practical application is essential for correctly answering performance-based questions and solidifying your understanding.
The cost for a data analytics exam in 2026 differs widely by provider. The official CompTIA Data+ (DA0-002) exam voucher costs $264 USD standalone, or $344 USD bundled with Retake Assurance, per CompTIA's store pricing. Meanwhile, the Google Data Analytics Professional Certificate is not a single exam but a 9-course Coursera series billed at $49/month (US/Canada) after a 7-day free trial — most learners finish for under $300 total. Always check the official certification body's website for the most current pricing, as fees can change and may not include training materials or retake vouchers.
