Oracle Cloud Infrastructure 2025 Generative AI Professional Sample Questions (Q45-Q50):

NEW QUESTION # 45
Given the following prompts used with a Large Language Model, classify each as employing the Chain-of-Thought, Least-to-Most, or Step-Back prompting technique:

  • A. "To understand the impact of greenhouse gases on climate change, let's start by defining what greenhouse gases are. Next, we'll explore how they trap heat in the Earth's atmosphere."A. 1: Step-Back, 2: Chain-of-Thought, 3: Least-to-MostB. 1: Least-to-Most, 2: Chain-of-Thought, 3: Step-BackC. 1: Chain-of-Thought, 2: Step-Back, 3: Least-to-MostD. 1: Chain-of-Thought, 2: Least-to-Most, 3: Step-Back
  • B. "Solve a complex math problem by first identifying the formula needed, and then solve a simpler version of the problem before tackling the full question."
  • C. "Calculate the total number of wheels needed for 3 cars. Cars have 4 wheels each. Then, use the total number of wheels to determine how many sets of wheels we can buy with $200 if one set (4 wheels) costs $50."

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Prompt 1: Shows intermediate steps (3 × 4 = 12, then 12 ÷ 4 = 3 sets, $200 ÷ $50 = 4)-Chain-of-Thought.
Prompt 2: Steps back to a simpler problem before the full one-Step-Back.
Prompt 3: OCI 2025 Generative AI documentation likely defines these under prompting strategies.


NEW QUESTION # 46
What does the Loss metric indicate about a model's predictions?

  • A. Loss describes the accuracy of the right predictions rather than the incorrect ones.
  • B. Loss is a measure that indicates how wrong the model's predictions are.
  • C. Loss indicates how good a prediction is, and it should increase as the model improves.
  • D. Loss measures the total number of predictions made by a model.

Answer: B

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 # 47
What is the function of the Generator in a text generation system?

  • A. To generate human-like text using the information retrieved and ranked, along with the user's original query
  • B. To collect user queries and convert them into database search terms
  • C. To store the generated responses for future use
  • D. To rank the information based on its relevance to the user's query

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation=
In a text generation system (e.g., with RAG), the Generator is the component (typically an LLM) that produces coherent, human-like text based on the user's query and any retrieved information (if applicable). It synthesizes the final output, making Option C correct. Option A describes a Retriever's role. Option B pertains to a Ranker. Option D is unrelated, as storage isn't the Generator's function but a separate system task. The Generator's role is critical in transforming inputs into natural language responses.
OCI 2025 Generative AI documentation likely defines the Generator under RAG or text generation workflows.


NEW QUESTION # 48
What does "Loss" measure in the evaluation of OCI Generative AI fine-tuned models?

  • A. The difference between the accuracy of the model at the beginning of training and the accuracy of the deployed model
  • B. The level of incorrectness in the model's predictions, with lower values indicating better performance
  • C. The improvement in accuracy achieved by the model during training on the user-uploaded dataset
  • D. The percentage of incorrect predictions made by the model compared with the total number of predictions in the evaluation

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Loss measures the discrepancy between a model's predictions and true values, with lower values indicating better fit-Option D is correct. Option A (accuracy difference) isn't loss-it's a derived metric. Option B (error percentage) is closer to error rate, not loss. Option C (accuracy improvement) is a training outcome, not loss's definition. Loss is a fundamental training signal.
OCI 2025 Generative AI documentation likely defines loss under fine-tuning metrics.


NEW QUESTION # 49
What is the characteristic of T-Few fine-tuning for Large Language Models (LLMs)?

  • A. It selectively updates only a fraction of weights to reduce the number of parameters.
  • B. It increases the training time as compared to Vanilla fine-tuning.
  • C. It updates all the weights of the model uniformly.
  • D. It selectively updates only a fraction of weights to reduce computational load and avoid overfitting.

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation=
T-Few fine-tuning (a Parameter-Efficient Fine-Tuning method) updates a small subset of the model's weights, reducing computational cost and mitigating overfitting compared to Vanilla fine-tuning, which updates all weights. This makes Option C correct. Option A describes Vanilla fine-tuning, not T-Few. Option B is incomplete, as it omits the overfitting benefit. Option D is false, as T-Few typically reduces training time due to fewer updates. T-Few balances efficiency and performance.
OCI 2025 Generative AI documentation likely describes T-Few under fine-tuningoptions.
