Question 1

In the context of Retrieval-Augmented Generation (RAG) for LLM applications, how does a vector database contribute to the retrieval process?

Options :

A : By storing pre-computed summaries of relevant documents.

B : By enabling efficient search for similar textual representations based on semantic closeness.

C : By directly generating responses based on vector representations of input prompts.

D : By training the LLM model on the vector data itself.

Answer: B

Question 2

When considering the capabilities of code models, multi-modal LLMs, and language agents, which of the following scenarios would be LEAST likely?

Options :

A : A code model is used to generate code snippets based on natural language descriptions.

B : A multi-modal LLM is used to translate a spoken language conversation with image references.
