Oracle Cloud Infrastructure 2025 Generative AI Professional Sample Questions (Q23-Q28):

NEW QUESTION # 23
What does a cosine distance of 0 indicate about the relationship between two embeddings?

A. They are completely dissimilar
B. They have the same magnitude
C. They are unrelated
D. They are similar in direction

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Cosine distance measures the angle between two vectors, where 0 means the vectors point in the same direction (cosine similarity = 1), indicating high similarity in embeddings' semantic content-Option C is correct. Option A (dissimilar) aligns with a distance of 1. Option B is vague-directional similarity matters. Option D (magnitude) isn't relevant-cosine ignores magnitude. This is key for semantic comparison.
OCI 2025 Generative AI documentation likely explains cosine distance under vector database metrics.

NEW QUESTION # 24
How does a presence penalty function in language model generation?

A. It applies a penalty only if the token has appeared more than twice.
B. It penalizes all tokens equally, regardless of how often they have appeared.
C. It penalizes a token each time it appears after the first occurrence.
D. It penalizes only tokens that have never appeared in the text before.

Answer: C

Explanation:
Comprehensive and Detailed In-Depth Explanation=
A presence penalty reduces the probability of tokens that have already appeared in the output, applying the penalty each time they reoccur after their first use, to discourage repetition. This makes Option D correct. Option A (equal penalties) ignores prior appearance. Option B is the opposite-penalizing unused tokens isn't the intent. Option C (more than twice) adds an arbitrary threshold not typically used. Presence penalty enhances output variety.OCI 2025 Generative AI documentation likely details presence penalty under generation control parameters.

NEW QUESTION # 25
What is the purpose of frequency penalties in language model outputs?

A. To randomly penalize some tokens to increase the diversity of the text
B. To reward the tokens that have never appeared in the text
C. To penalize tokens that have already appeared, based on the number of times they have been used
D. To ensure that tokens that appear frequently are used more often

Answer: C

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Frequency penalties reduce the likelihood of repeating tokens that have already appeared in the output, based on their frequency, to enhance diversity and avoid repetition. This makes Option B correct. Option A is the opposite effect. Option C describes a different mechanism (e.g., presence penalty in some contexts). Option D is inaccurate, as penalties aren't random but frequency-based.
OCI 2025 Generative AI documentation likely covers frequency penalties under output control parameters.
Below is the next batch of 10 questions (11-20) from your list, formatted as requested with detailed explanations. These answers are based on widely accepted principles in generative AI and Large Language Models (LLMs), aligned with what is likely reflected in the Oracle Cloud Infrastructure (OCI) 2025 Generative AI documentation. Typographical errors have been corrected for clarity.

NEW QUESTION # 26
Which is a characteristic of T-Few fine-tuning for Large Language Models (LLMs)?

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

Answer: A

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 # 27
What is prompt engineering in the context of Large Language Models (LLMs)?

A. Adjusting the hyperparameters of the model
B. Training the model on a large dataset
C. Adding more layers to the neural network
D. Iteratively refining the ask to elicit a desired response

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Prompt engineering involves crafting and refining input prompts to guide an LLM to produce desired outputs without altering its internal structure or parameters. It's an iterative process that leverages the model's pre-trained knowledge, making Option A correct. Option B is unrelated, as adding layers pertains to model architecture design, not prompting. Option C refers to hyperparameter tuning (e.g., temperature), not prompt engineering. Option D describes pretraining or fine-tuning, not prompt engineering.
OCI 2025 Generative AI documentation likely covers prompt engineering in sections on model interaction or inference.
