Oracle Cloud Infrastructure 2025 Generative AI Professional Sample Questions (Q63-Q68):

NEW QUESTION # 63
Which is a characteristic of T-Few fine-tuning for Large Language Models (LLMs)?

A. It updates all the weights of the model uniformly.
B. It does not update any weights but restructures the model architecture.
C. It increases the training time as compared to Vanilla fine-tuning.
D. It selectively updates only a fraction of the model's weights.

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation=
T-Few fine-tuning, a Parameter-Efficient Fine-Tuning (PEFT) method, updates only a small fraction of an LLM's weights, reducing computational cost and overfitting risk compared to Vanilla fine-tuning (all weights). This makes Option C correct. Option A describes Vanilla fine-tuning. Option B is false-T-Few updates weights, not architecture. Option D is incorrect-T-Few typically reduces training time. T-Few optimizes efficiency.
OCI 2025 Generative AI documentation likely highlights T-Few under fine-tuning options.

NEW QUESTION # 64
An AI development company is working on an advanced AI assistant capable of handling queries in a seamless manner. Their goal is to create an assistant that can analyze images provided by users and generate descriptive text, as well as take text descriptions and produce accurate visual representations. Considering the capabilities, which type of model would the company likely focus on integrating into their AI assistant?

A. A language model that operates on a token-by-token output basis
B. A diffusion model that specializes in producing complex outputs.
C. A Large Language Model-based agent that focuses on generating textual responses
D. A Retrieval Augmented Generation (RAG) model that uses text as input and output

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation=
The task requires bidirectional text-image capabilities: analyzing images to generate text and generating images from text. Diffusion models (e.g., Stable Diffusion) excel at complex generative tasks, including text-to-image and image-to-text with appropriate extensions, making Option A correct. Option B (LLM) is text-only. Option C (token-based LLM) lacks image handling. Option D (RAG) focuses on text retrieval, not image generation. Diffusion models meet both needs.
OCI 2025 Generative AI documentation likely discusses diffusion models under multimodal applications.

NEW QUESTION # 65
What does the Loss metric indicate about a model's predictions?

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

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Loss is a metric that quantifies the difference between a model's predictions and the actual target values, indicating how incorrect (or "wrong") the predictions are. Lower loss means better performance, making Option B correct. Option A is false-loss isn't about prediction count. Option C is incorrect-loss decreases as the model improves, not increases. Option D is wrong-loss measures overall error, not just correct predictions. Loss guides training optimization.
OCI 2025 Generative AI documentation likely defines loss under model training and evaluation metrics.

NEW QUESTION # 66
Which technique involves prompting the Large Language Model (LLM) to emit intermediate reasoning steps as part of its response?

A. Least-to-Most Prompting
B. Chain-of-Thought
C. Step-Back Prompting
D. In-Context Learning

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Chain-of-Thought (CoT) prompting explicitly instructs an LLM to provide intermediate reasoning steps, enhancing complex task performance-Option B is correct. Option A (Step-Back) reframes problems, not emits steps. Option C (Least-to-Most) breaks tasks into subtasks, not necessarily showing reasoning. Option D (In-Context Learning) uses examples, not reasoning steps. CoT improves transparency and accuracy.
OCI 2025 Generative AI documentation likely covers CoT under advanced prompting techniques.

NEW QUESTION # 67
Which role does a "model endpoint" serve in the inference workflow of the OCI Generative AI service?

A. Evaluates the performance metrics of the custom models
B. Hosts the training data for fine-tuning custom models
C. Serves as a designated point for user requests and model responses
D. Updates the weights of the base model during the fine-tuning process

Answer: C

Explanation:
Comprehensive and Detailed In-Depth Explanation=
A "model endpoint" in OCI's inference workflow is an API or interface where users send requests and receive responses from a deployed model-Option B is correct. Option A (weight updates) occurs during fine-tuning, not inference. Option C (metrics) is for evaluation, not endpoints. Option D (training data) relates to storage, not inference. Endpoints enable real-time interaction.
OCI 2025 Generative AI documentation likely describes endpoints under inference deployment.
