Question 1

Which of the following statements is true about OCI Generative AI service?

Options :

A : It provides pre-trained large language models (LLMs) only.

B : It allows fine-tuning pre-trained models with your own data.

C : It requires users to manage their own AI clusters for inference.

D : It is limited to text generation tasks only.

Answer: B

Question 2

Given the following code:

chain - prompt | 11m

Which statement is true about LangChain Expression Language (LCEL)?

Options :

A : LCEL is an older Python library for building Large Language Models.

B : LCEL is a declarative and preferred way to compose chains together.

C : LCEL is a programming language used to write documentation for LangChain.

D : LCEL is a legacy method for creating chains in LangChain.

Answer: B

Question 3

What is the primary function of the "temperature" parameter in the OCI Generative AI Generation models?

Options :

A : Specifies a string that tells the model to stop generating more content

B : Determines the maximum number of tokens the model can generate per response

C : Controls the randomness of the model’s output, affecting its creativity

D : Assigns a penalty to tokens that have already appeared in the preceding text

Answer: C

Question 4

What does the Loss metric indicate about a model's predictions?

Options :

A : Loss is a measure that indicates how wrong the model-s predictions are.

B : Loss measures the total number of predictions made by a model.

C : Loss describes the accuracy of the right predictions rather than the incorrect ones.

D : Loss indicates how good a prediction is, and it should increase as the model improves.

Answer: A

Question 5

What is a potential drawback of using RAG in OCI Generative AI applications?

Options :

A : RAG is computationally expensive due to the retrieval process.

B : RAG can only be used with specific pre-trained models offered by OCI.

C : RAG requires extensive training data for the Retriever component.

D : RAG outputs are limited to factual summaries and lack creativity.
