CompTIA Data+ DA0-002 (V2) Practice Question

The correct answer is that a .txt file format does not store metadata or formatting, requiring the analyst to determine the data's structure. A .txt file is a plain text file, meaning it contains only text characters without any embedded information about formatting (like bold or italics), or structure (like defined columns). When ingesting data from a .txt file, the analyst must inspect the file to understand its layout, such as whether the data is separated by commas, tabs, or another delimiter, and determine the correct character encoding (e.g., UTF-8, ANSI) to read the characters correctly.

The other options are incorrect. Describing data in a nested, hierarchical structure is characteristic of a .json or .xml file. A file that is a binary format requiring a specific driver is typical of proprietary database files, not universally readable text files. Lastly, while a .txt file might have a header row, this is simply the first line of text and is not inherent schema information enforced by the file format itself.
