Exam Certified Generative AI Engineer Associate topic 1 question 19 discussion

A works by using a retriever to retrieve information from a new document and then inserting it into the prompt to pass it on to the LLM. This structure is effective in providing up-to-date information, reflecting frequently updated documentation, while minimizing cost and development effort. B describes the update frequency of LLM, but lacks a description of the actual application architecture. C only mentions prompt engineering and LLM, and doesn't explain how to handle updates for new documents. D describes an agent-using approach, but lacks specifics on how an agent-using structure would achieve the same effective information retrieval and insertion as A.
