A county-fair livestock-registration suite must log who asked, fetch last year’s weigh-in cases, wrap them in a house prompt, and only then call the model. Which component typically handles authentication, data retrieval, prompt preparation, and interaction with the LLM?
Select an answer to reveal the explanation.
Short Explanation
The back-end is the kitchen that takes the order, checks credentials, pulls ingredients, writes the recipe card, and talks to the cook. Authentication, retrieval, prompt prep, and the model call live there — not in the form alone or a single store.
Full Explanation
Architecture for LLM-powered testing places authentication, data retrieval, prompt preparation, and LLM interaction in the back-end. The front-end captures input; databases supply structured or semantic data. Treating the back-end as that orchestration layer keeps security and prompt construction consistent before the model runs.
