Question 1

How does the integration of a vector database into Retrieval-Augmented Generation (RAG)-based Large Language Models (LLMs) fundamentally alter their responses?

A : It transforms their architecture from a neural network to a traditional database system.

B : It shifts the basis of their responses from pretrained internal knowledge to real-time data retrieval.

C : It enables them to bypass the need for pretraining on large text corpora.

D : It limits their ability to understand and generate natural language.

Answer: B

Question 2

Which role does a "model endpoint" serve in the inference workflow of the OCI Generative AI service?

B : Serves as a designated point for user requests and model responses

C : Evaluates the performance metrics of the custom models

D : Hosts the training data for fine-tuning custom models

Answer: B

Question 3

What is the role of temperature in the decoding process of a Large Language Model (LLM)?

A : To increase the accuracy of the most likely word in the vocabulary

B : To determine the number of words to generate in a single decoding step

C : To decide to which part of speech the next word should belong

D : To adjust the sharpness of probability distribution over vocabulary when selecting the next word

Answer: D

Question 4

In the context of generating text with a Large Language Model (LLM), what does the process of greedy decoding entail?

C : Choosing the word with the highest probability at each step of decoding

D : Using a weighted random selection based on a modulated distribution

Answer: C

Question 5
