A security architect is designing a generative AI solution for a financial institution that requires strict adherence to data freshness and granular access control. The solution must answer employee queries based on internal policy documents that change weekly. Which architectural approach provides the BEST balance of up-to-date information retrieval and document-level security permissions without requiring frequent, expensive model retraining?
Answer and explanation
Correct answer: B
Retrieval-Augmented Generation (RAG) allows the system to fetch the most current data from an external source (vector database) at query time. By integrating Access Control Lists (ACLs) at the retrieval layer, the system ensures users only receive answers based on documents they are authorized to view. Fine-tuning is computationally expensive, introduces latency in knowledge updates, and makes granular access control difficult since knowledge is baked into the model weights.
