Question 1

How can fine-tuning an LLM model with OCI Generative AI contribute to improved performance of semantic search in your application?

A : By enabling the LLM to directly generate documents based on semantic similarity.

B : By allowing the LLM to interpret the retrieved documents and provide more context-aware responses.

C : By improving the accuracy of vector representations generated for the documents in the database.

D : By optimizing the search algorithms used by the vector database for specific LLM tasks.

Answer: B

Question 2

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

A : Updates the weights of the base model during the fine-tuning process

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

How does OCI Generative AI contribute to a secure data lifecycle when working with your custom datasets?

A : Users are responsible for implementing their own data encryption methods.

B : OCI Generative AI automatically encrypts data at rest and in transit by default.

C : Data uploaded to OCI Generative AI becomes publicly accessible for collaboration.

D : Users retain full control over data location and access within the O

Answer: B

Question 4

What benefit does using vector databases offer in the context of building fault-tolerant LLM applications with OCI Generative AI?

A : They enable real-time generation of new vector representations for unseen data.

B : They improve the interpretability of the LLM model-s decision-making process

C : They provide a mechanism for caching frequently retrieved documents.

D : They allow for incremental updates to the vector database without retraining the LLM model.

Answer: D

Question 5

What security best practice should be considered when configuring access to your deployed model endpoint?

A : Leaving the endpoint publicly accessible for ease of use.

B : Restricting access using IAM policies and authentication tokens.

C : Sharing endpoint details with all relevant users within your organization.

D : Disabling monitoring for the endpoint to reduce resource consumption

Answer: B
