20+ practice questions focused on Data Governance — one of the most tested topics on the CompTIA Data+ (DA0-002) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Data Governance PracticeA data analyst notices that a line chart showing monthly sales over the past two years has a steep drop in one month. Upon investigation, the analyst discovers that a new sales region was added mid-month and the data was not normalized. Which of the following best practices should the analyst apply to communicate this insight accurately?
Explanation: The core issue is that the sales data is not normalized by region, causing a misleading drop when a new region was added mid-month. By normalizing the data (e.g., calculating per-region averages or percentages) and explicitly noting the anomaly in the report, the analyst ensures accurate communication of insights. This aligns with the DA0-001 domain of Communicating Data Insights, where transparency and data integrity are paramount.
A data analyst encounters the above error log when trying to connect to a database. The analyst needs to explain the issue to the database administrator. Which of the following correctly describes the problem?
Explanation: In this scenario of a database connection failure, the most likely cause is that the connection pool has reached its maximum limit. This means all available connections are in use, preventing new connections. The other options are less common causes for such connection issues.
A healthcare analytics team is responsible for producing a monthly dashboard for hospital administrators. The dashboard includes key metrics such as patient admission rates, average length of stay, readmission rates, and bed occupancy. For the current month, the data shows a significant increase in average length of stay. The data analyst suspects that this increase is due to a new chronic disease management program that was implemented at the beginning of the month. However, the analyst also notices that the data for the previous month had an error: some discharge dates were incorrectly recorded, causing the average length of stay to be artificially low. The analyst needs to communicate the insights to the administrators, who are concerned about the increase. Which of the following is the best course of action?
Explanation: The best course of action because it addresses both the data quality issue and the business concern. By correcting the previous month's erroneous discharge dates, the analyst recalculates the true baseline, ensuring the reported increase in average length of stay is accurate. Presenting the corrected data alongside an explanation of the new chronic disease management program provides a complete, transparent narrative that separates the impact of the data error from the program's effect, which is essential for informed decision-making by hospital administrators.
An analyst is creating a report to show the relationship between advertising spend and website traffic over the past 12 months. The data has a few outliers due to special promotional events. Which chart type should the analyst use to clearly show the trend while minimizing the impact of outliers?
Explanation: A scatter plot with a trend line (Option D) is the best choice because it plots each data point individually, allowing the analyst to see the overall relationship between advertising spend and website traffic while the trend line (often a linear regression line) smooths out the influence of outliers. This chart type minimizes the visual impact of extreme values by focusing on the central tendency and direction of the data, making it ideal for identifying trends over 12 months despite promotional event spikes.
During a presentation, a stakeholder questions the validity of a data insight because the sample size appears small. The analyst knows the sample is statistically significant. What is the best way to address this concern?
Explanation: It directly addresses the stakeholder's concern by explaining the statistical concepts of margin of error and confidence interval, which demonstrate that the sample size is sufficient for the desired level of precision. This approach validates the data insight's reliability without dismissing the stakeholder's valid question, aligning with best practices in communicating data insights.

Start with 10 questions to gauge your current understanding of Data Governance. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Data Governance questions on the DA0-002 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Data Governance is tested as part of the CompTIA Data+ (DA0-002) blueprint. Practicing with targeted Data Governance questions ensures you can handle any format or difficulty that appears.
