CompTIA Data+ DA0-002 (V2) Practice Question

The correct answer is a large language model (LLM). LLMs are a type of artificial intelligence specifically designed to understand, process, and generate human-like text based on the vast amounts of data they are trained on. This makes them ideal for tasks like summarizing unstructured text, analyzing sentiment, and identifying themes from customer reviews.

• Robotic process automation (RPA) is incorrect because it is designed to automate repetitive, rule-based tasks by mimicking human interactions with digital systems, such as data entry or file transfers. It does not have the capability to interpret unstructured text and generate novel summaries.
• A dimensional table is a data warehouse structure that stores descriptive attributes to provide context to facts in a fact table. It is a way to organize structured data for analysis, not a tool for processing and summarizing unstructured text.
• While an LLM is a type of foundational model, 'foundational model' is a broader category that can include models for images, audio, and other data types, not just text. 'Large language model' is the more specific and therefore most appropriate choice for a task that exclusively involves processing and generating text.
