CompTIA DA0-002 Dumps Questions Answers

This question falls under the Visualization and Reporting domain, focusing on tailoring reports for different audiences. The same data is used for three distinct groups (supervisors, city council, public), requiring differentiation.

Persona type (Option A): Persona types define the audience’s needs and preferences (e.g., supervisors need operational details, the city council needs summaries, the public needs simplified data), making this the best way to differentiate the reports.

Detail levels (Option B): Detail levels are a result of persona types, not the method of differentiation.

Accessibility (Option C): Accessibility ensures access for all users (e.g., screen readers), but it’s not the primary way to differentiate content.

Sensitivity (Option D): Sensitivity determines data access (e.g., confidential vs. public), but the scenario implies all reports use the same data, just presented differently.

The DA0-002 Visualization and Reporting domain emphasizes "translating business requirements to form the appropriate visualization," and persona types guide report differentiation for diverse audiences.

This question pertains to the Data Concepts and Environments domain, focusing on data repositories. The task is to identify a repository that stores raw, unformatted data.

Data warehouse (Option A): A data warehouse stores structured, processed data in a predefined schema, not raw data.

Data silo (Option B): A data silo is an isolated repository, often structured, not designed for raw data storage.

Data mart (Option C): A data mart is a subset of a data warehouse, also storing structured data.

Data lake (Option D): A data lake stores raw, unformatted data in its original format (structured, semi-structured, or unstructured), making it the correct choice.

The DA0-002 Data Concepts and Environments domain includes understanding "different types of databases and data repositories," and a data lake is designed for raw data storage.

This question falls under the Data Governance domain, focusing on data access and security troubleshooting. The analyst reset their password, but the recurring analysis failed to log in, indicating a mismatch.

The company changed its database authentication method (Option A): This would affect all users, not just the analyst, and there’s no indication of a broader change.

The password expiration process locked the account (Option B): The analyst reset the password as required, so the account isn’t likely locked due to expiration.

The analyst did not change the password used to launch the report (Option C): Recurring analyses often use stored credentials. If the analyst updated their password but didn’t update the stored credentials for the analysis, the login would fail, making this the most likely reason.

The company is experiencing issues with password replication (Option D): This is possible but less likely without evidence of broader system issues.

The DA0-002 Data Governance domain includes "data privacy concepts," and ensuring stored credentials match updated passwords is a common issue in recurring analyses.
