Question #1 (Topic: demo questions)

[Visualization and Reporting] A data analyst is generating a custom report for a Chief Executive
Officer's executive meeting. Later, the analyst learns that other custom reports will be required for
future executive meetings. Which of the following delivery methods should the analyst use?

A.
Adhoc 
B.
Real-time 
C.
Recurring 
D.
Self-service
Correct Answer: C
Explanation:
C. Recurring is the correct answer because the analyst has learned that similar reports will be needed for future executive meetings. A recurring report can be scheduled to generate automatically at regular intervals, ensuring consistent and timely delivery without creating a new report each time. This approach improves efficiency, reduces manual effort, and is ideal for reports that are required repeatedly. Therefore, a recurring delivery method best fits the scenario.
Question #2 (Topic: demo questions)

[Data Governance] Which of the following explains the purpose of UAT?

A.
To begin the software application development process to enhance user experience
B.
To ensure all parts of the software application work together after each sprint
C.
To review software application crashes, create patches, and deploy to users
D.
To validate and verify that a software application meets the needs and requirements of users explanation
Correct Answer: D
Explanation:

D. To validate and verify that a software application meets the needs and requirements of users is correct because User Acceptance Testing (UAT) is performed by end users or stakeholders to confirm that the system works as expected in real-world scenarios. It ensures the application meets business requirements and is suitable for release. UAT happens after system and integration testing and focuses on user satisfaction rather than technical debugging. Therefore, its main purpose is validation against user needs and requirements.
Question #3 (Topic: demo questions)

[Data Concepts and Environments]
A report triggers an error that prevents information from being displayed. However, the report was
functional before a database upgrade. Which of the following should a data analyst do first to
troubleshoot the problem?

A.
Ensure the system has permissions for the report service.
B.
Change the report's refresh rate.
C.
Verify the connection to the database.
D.
Check whether the data structures were modified.
Correct Answer: C
Explanation:

The first step in troubleshooting a report that was working before a database upgrade is to confirm whether the report can still connect to the database. Database upgrades often cause connection issues due to changes in endpoints, credentials, or drivers. Before checking deeper issues like schema changes or permissions, it is best practice to first ensure the data source connection is still valid. If the connection works, then further investigation into structural changes can follow.
Question #4 (Topic: demo questions)

[Data Acquisition and Preparation]
Which of the following best describes the semi-structured data that is gathered when web scraping?


A.
JSON
B.
CSV
C.
CSS
D.
HTML
Correct Answer: D
Explanation:

Web scraping collects data directly from web pages, and those pages are originally written in HTML, which is considered semi-structured because it has a flexible tag-based format rather than a strict tabular structure. While scraped data is often later converted into formats like JSON, the actual source format being extracted from websites is HTML. CSV is structured data, CSS is for styling web pages, and JSON is a structured/semi-structured format but not the raw format typically gathered during scraping.
Question #5 (Topic: demo questions)

[Visualization and Reporting]

Which of the following is the best tool for creating a dynamic dashboard?

A.
Power BI
B.
RStudio
C.
Excel
D.
SAS
Correct Answer: A
Explanation:

Power BI is specifically designed for building interactive and dynamic dashboards with real-time data connections, visualizations, and easy sharing capabilities. It allows users to drill down into data, apply filters, and update visuals automatically as data changes. While Excel can create basic dashboards and RStudio or SAS are powerful for analysis and statistical work, Power BI is the most suitable and widely used tool for dynamic business dashboards.
