Master the CompTIA Data+ exam with our comprehensive Q&A collection. Review questions by topic, understand explanations, and build confidence for exam day.
Strategies to help you tackle CompTIA Data+ exam questions effectively
Allocate roughly 1-2 minutes per question. Flag difficult questions and return to them later.
Pay attention to keywords like 'MOST', 'LEAST', 'NOT', and 'EXCEPT' in questions.
Use elimination to narrow down choices. Often 1-2 options can be quickly ruled out.
Focus on understanding why answers are correct, not just memorizing facts.
Practice with real exam-style questions for CompTIA Data+
Consistency is correct because the data contains different formats or representations for the same type of information across records. This inconsistency in how gender is recorded ('M'/'F' vs 'Male'/'Female') makes the data difficult to aggregate and analyze. Accuracy refers to correctness of values, completeness refers to missing data, and timeliness refers to whether data is current.
Structured data is data that is organized in a fixed format with clearly defined data types, typically stored in relational databases with rows and columns. This makes it easily searchable and analyzable. Option B describes unstructured data, Option C describes semi-structured data, and Option D describes characteristics that could apply to any data type depending on the use case.
API integration is the correct answer because the analyst is connecting to and extracting data from a REST API, which is a structured programmatic interface designed for data exchange. Web scraping involves extracting data from websites by parsing HTML, database querying involves SQL statements against databases, and file parsing involves reading data from static files. APIs provide a more reliable and structured method for data extraction than scraping.
A gauge chart is most appropriate for showing progress toward a specific target or goal, as it clearly displays current performance against a defined benchmark in an easy-to-understand visual format. Executives can quickly see if targets are being met. Scatter plots show relationships between variables, box plots show statistical distributions, and heat maps show patterns across two dimensions. None of these alternatives effectively communicate progress toward a single target value.
Filtering is not a sampling method; it is a data manipulation technique that selects records based on specific criteria. Sampling methods involve selecting a representative subset of data from a population, typically using random, stratified, or systematic approaches. Filtering removes records that don't meet certain conditions, which may introduce bias and is different from statistical sampling techniques designed to maintain representativeness.

Common questions about the exam format and questions
The CompTIA Data+ exam typically contains 50-65 questions. The exact number may vary, and not all questions may be scored as some are used for statistical purposes.
The exam includes multiple choice (single answer), multiple response (multiple correct answers), and scenario-based questions. Some questions may include diagrams or code snippets that you need to analyze.
Questions are weighted based on the exam domain weights. Topics with higher percentages have more questions. Focus your study time proportionally on domains with higher weights.
Yes, most certification exams allow you to flag questions for review and return to them before submitting. Use this feature strategically for difficult questions.
Practice questions are designed to match the style, difficulty, and topic coverage of the real exam. While exact questions won't appear, the concepts and question formats will be similar.
