CompTIA Data+ Exam Sample Questions (Q18-Q23):

NEW QUESTION # 18
A report was previously working but now gives the following error:
The column FullName is invalid or does not exist.
Which of the following actions should a data analyst take to investigate the issue?

Answer: B

Explanation:
Querying the table allows the analyst to verify the current schema and confirm whether the column exists or has been renamed or removed, directly addressing the cause of the error.


NEW QUESTION # 19
A data analyst pulls a table similar to the following one:

Which of the following best explains the data issue with TypeID?

Answer: A

Explanation:
The TypeID column contains information that is already present in the Type column. Values such as "Full Time 1", "Part Time 2", and "Full Time 3" repeat the employment type while adding an identifier, resulting in unnecessary duplication of information. This is an example of redundancy because the same data is being stored in multiple places.


NEW QUESTION # 20
Which of the following data repositories stores unstructured and structured data?

Answer: D

Explanation:
This question falls under theData Concepts and Environmentsdomain of CompTIA Data+ DA0-002, which involves understanding different types of data repositories and their characteristics. The task is to identify a repository that can store both unstructured and structured data.
* Data store (Option A): A data store is a general term for any data repository, but it's not specific enough to confirm it stores both unstructured and structured data.
* Data silo (Option B): A data silo is an isolated data repository, often structured, and not typically designed for unstructured data.
* Data mart (Option C): A data mart is a subset of a data warehouse, focused on structured data for specific business areas, not unstructured data.
* Data lake (Option D): A data lake is a centralized repository that stores raw data in its native format, including both structured (e.g., tables) and unstructured (e.g., text, images) data, 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 specifically designed to handle both unstructured and structured data.
