CompTIA Data+ Exam (2025) Sample Questions (Q73-Q78):NEW QUESTION # 73
A company gives users adequate data access permissions to allow them to fulfill their duties but nothing more. Which of the following concepts best describes this practice?
A. Hierarchical access
B. Zero Trust
C. Least privilege
D. Active Directory
Answer: C
Explanation:
This question pertains to theData Governancedomain, focusing on data security and access control principles. The company restricts access to the minimum needed for duties, which aligns with a specific security concept.
* Active Directory (Option A): Active Directory is a tool for managing users and permissions, not a concept.
* Hierarchical access (Option B): Hierarchical access implies access based on roles in a hierarchy, but it doesn't specifically focus on minimal access.
* Zero Trust (Option C): Zero Trust requires continuous verification for all access, which is broader than just minimal permissions.
* Least privilege (Option D): Least privilege ensures users have only the permissions necessary for their duties, which matches the scenario.
The DA0-002 Data Governance domain includes "data privacy concepts," and least privilege is afundamental principle for secure access control.

NEW QUESTION # 74
A manager needs a report to be sent by email every Monday for the next six months. Which of the following is the best way to accomplish this task?
A. Developing a recurring process
B. Building self-service access
C. Creating a data snapshot
D. Waiting for the request each week
Answer: A
Explanation:
This question falls under theVisualization and Reportingdomain, focusing on report delivery methods. The task requires a report to be emailed every Monday for six months, indicating a scheduled, repeating process.
* Building self-service access (Option A): Self-service allows users to generate reports on-demand, but the manager wants automatic delivery.
* Creating a data snapshot (Option B): A snapshot captures data at a specific point, not suitable for recurring delivery over six months.
* Developing a recurring process (Option C): A recurring process schedules the report to be generated and emailed every Monday, meeting the requirement for automated delivery over six months.
* Waiting for the request each week (Option D): This is manual and inefficient, not suitable for a six- month schedule.
The DA0-002 Visualization and Reporting domain includes "the appropriate visualization in the form of a report" with delivery methods, and a recurring process is ideal for scheduled email delivery.

NEW QUESTION # 75
Which of the following data sources makes online data consumption easier?
A. Data mart
B. Web scraping
C. Database
D. Application programming interface
Answer: D
Explanation:
This question pertains to theData Concepts and Environmentsdomain, focusing on data sources that facilitate online data access. The task is to identify a source that simplifies online data consumption.
* Data mart (Option A): A data mart stores structured data for specific business areas, typically accessed internally, not designed for online consumption.
* Web scraping (Option B): Web scraping extracts data from websites but requires parsing and cleaning, which isn't necessarily "easier."
* Database (Option C): Databases store data but aren't inherently designed for online consumption without an interface.
* Application programming interface (Option D): An API provides a structured way to access data online, often in formats like JSON, making data consumption easier for applications and users.
The DA0-002 Data Concepts and Environments domain includes understanding "data sources," and APIs are specifically designed to simplify online data access.

NEW QUESTION # 76
A data analyst needs to get an accurate idea of how data components are automated. Which of the following types of documentation should the analyst review first?
A. Data lineage
B. Data explainability report
C. Data dictionary
D. Data flow diagram
Answer: D
Explanation:
This question pertains to theData Concepts and Environmentsdomain, focusing on documentation for understanding data processes. The analyst needs to understand automation of data components, which involves data movement and processes.
* Data flow diagram (Option A): A data flow diagram (DFD) visualizes how data moves through systems, including automated processes, making it the best starting point.
* Data explainability report (Option B): This is related to AI/ML model transparency, not data automation.
* Data dictionary (Option C): A data dictionary defines data elements, not how they're automated.
* Data lineage (Option D): Data lineage tracks data origin and transformations but doesn't focus on automation processes.
The DA0-002 Data Concepts and Environments domain includes understanding "data schemas and dimensions," and a data flow diagram is key for visualizing automation.

NEW QUESTION # 77
A data company needs a visualization that shows the availability zones from the last ten years and any future availability zones that the company will be using in the next five years. Which of thefollowing is the most appropriate visualization to display this information?
A. Pie chart
B. Mosaic plot
C. Bar chart
D. Map
Answer: D
Explanation:
This question falls under theVisualization and Reportingdomain of CompTIA Data+ DA0-002, focusing on selecting the appropriate visualization for a specific dataset. The task is to show availability zones over a 15- year period (past and future), which involves a geographical element since availability zones are typically location-based.
* Bar chart (Option A): Bar charts are good for comparing categorical data but don't effectively show geographical locations or time-based trends across zones.
* Mosaic plot (Option B): Mosaic plots display relationships between categorical variables, not suitable for geographical or time-series data.
* Map (Option C): A map can display availability zones geographically, with annotations or layers to show changes over time (past 10 years and future 5 years), making it the most appropriate visualization.
* Pie chart (Option D): Pie charts show proportions of a whole, not suitable for geographical or time- based data.
The DA0-002 Visualization and Reporting domain emphasizes "translating business requirements to form the appropriate visualization," and a map is the best choice for displaying geographical availability zones over time.
