CompTIA Data+ Exam Sample Questions (Q195-Q200):

NEW QUESTION # 195
A data analyst is creating a dashboard for a group of visually impaired stakeholders. Which of the following communication approaches is best?

Answer: C

Explanation:
Incorporating audio accessibility functions ensures that visually impaired users can interpret and interact with dashboard content independently, aligning with accessibility best practices.


NEW QUESTION # 196
A sales manager wants a dashboard that shows sales aggregated by region and identifies high-volume sales by salesperson per region. Which of the following communication techniques best displays this information?

Answer: B

Explanation:
This question pertains to theVisualization and Reportingdomain, focusing on dashboard features for displaying data. The dashboard needs to show aggregated sales by region and allow identification of high- volume sales by salesperson within each region.
* Defined parameters (Option A): Parameters set specific values (e.g., a date range), but they don't directly enable interaction with aggregated data.
* Filter options (Option B): Filter options allow the user to select a region and then view salespersons within that region, enabling the identification of high-volume sales per region interactively.
* Level of detail (Option C): Level of detail determines the granularity of data shown but doesn't facilitate interactive exploration.
* User persona (Option D): User personas guide dashboard design but aren't a communication technique for displaying data.
The DA0-002 Visualization and Reporting domain emphasizes "translating business requirements to form the appropriate visualization," and filter options best enable the interactive analysis required.
Reference: CompTIA Data+ DA0-002 Draft Exam Objectives, Domain 4.0 Visualization and Reporting.


NEW QUESTION # 197
A data engineer needs to add a process that will run after an employee table is loaded. The engineer does not know the name of the process that loads employee data. Which of the following is the best document for the engineer to review to find this information?

Answer: A

Explanation:
A data lineage report documents the movement and transformation of data throughout systems and processes. It shows where data originates, how it is processed, and the dependencies between processes. Reviewing the data lineage report would help the engineer identify the process responsible for loading the employee table and determine where to add the subsequent process.

Answer: A

Explanation:
This question pertains to theData Governancedomain, focusing on data quality validation techniques. The task is to validate that the number of records matches expectations, which requires a specific type of assessment.
* Source control (Option A): Source control (e.g., Git) manages code versions, not dataset validation.
* Unit test (Option B): A unit test checks a specific component of a process, such as verifying that the number of records in a dataset matches the expected count, making it the best fit.
* Stress test (Option C): Stress tests evaluate system performance under load, not record counts.
* Health check (Option D): A health check monitors system status but isn't specific to validating record counts.
The DA0-002 Data Governance domain includes "data quality control concepts," and unit tests are a standard method for validating specific data outcomes like record counts.
