Oracle Cloud Infrastructure 2025 Generative AI Professional Sample Questions (Q11-Q16):

NEW QUESTION # 11
Accuracy in vector databases contributes to the effectiveness of Large Language Models (LLMs) by preserving a specific type of relationship. What is the nature of these relationships, and why arethey crucial for language models?

  • A. Linear relationships; they simplify the modeling process
  • B. Semantic relationships; crucial for understanding context and generating precise language
  • C. Temporal relationships; necessary for predicting future linguistic trends
  • D. Hierarchical relationships; important for structuring database queries

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Vector databases store embeddings that preserve semantic relationships (e.g., similarity between "dog" and "puppy") via their positions in high-dimensional space. This accuracy enables LLMs to retrieve contextually relevant data, improving understanding and generation, making Option B correct. Option A (linear) is too vague and unrelated. Option C (hierarchical) applies more to relational databases. Option D (temporal) isn't the focus-semantics drives LLM performance. Semantic accuracy is vital for meaningful outputs.
OCI 2025 Generative AI documentation likely discusses vector database accuracy under embeddings and RAG.


NEW QUESTION # 12
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 increases the training time as compared to Vanilla fine-tuning.
  • C. It does not update any weights but restructures the model architecture.
  • D. It updates all the weights of the model uniformly.

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 # 13
Which statement is true about the "Top p" parameter of the OCI Generative AI Generation models?

  • A. "Top p" selects tokens from the "Top k" tokens sorted by probability.
  • B. "Top p" determines the maximum number of tokens per response.
  • C. "Top p" limits token selection based on the sum of their probabilities.
  • D. "Top p" assigns penalties to frequently occurring tokens.

Answer: C

Explanation:
Comprehensive and Detailed In-Depth Explanation=
"Top p" (nucleus sampling) selects tokens whose cumulative probability exceeds a threshold (p), limiting the pool to the smallest set meeting this sum, enhancing diversity-Option C is correct. Option A confuses it with "Top k." Option B (penalties) is unrelated. Option D (max tokens) is a different parameter. Top p balances randomness and coherence.
OCI 2025 Generative AI documentation likely explains "Top p" under sampling methods.
Here is the next batch of 10 questions (81-90) from your list, formatted as requested with detailed explanations. The 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 # 14
How do Dot Product and Cosine Distance differ in their application to comparing text embeddings in natural language processing?

  • A. Dot Product calculates the literal overlap of words, whereas Cosine Distance evaluates the stylistic similarity.
  • B. Dot Product measures the magnitude and direction of vectors, whereas Cosine Distance focuses on the orientation regardless of magnitude.
  • C. Dot Product is used for semantic analysis, whereas Cosine Distance is used for syntactic comparisons.
  • D. Dot Product assesses the overall similarity in content, whereas Cosine Distance measures topical relevance.

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Dot Product computes the raw similarity between two vectors, factoring in both magnitude and direction, while Cosine Distance (or similarity) normalizes for magnitude, focusing solely on directional alignment (angle), making Option C correct. Option A is vague-both measure similarity, not distinct content vs. topicality. Option B is false-both address semantics, not syntax. Option D is incorrect-neither measures word overlap or style directly; they operate on embeddings. Cosine is preferred for normalized semantic comparison.
OCI 2025 Generative AI documentation likely explains these metrics under vector similarity in embeddings.


NEW QUESTION # 15
What is the role of temperature in the decoding process of a Large Language Model (LLM)?

  • A. To increase the accuracy of the most likely word in the vocabulary
  • B. To determine the number of words to generate in a single decoding step
  • C. To decide to which part of speech the next word should belong
  • D. To adjust the sharpness of probability distribution over vocabulary when selecting the next word

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Temperature is a hyperparameter in the decoding process of LLMs that controls the randomness of word selection by modifying the probability distribution over the vocabulary. A lower temperature (e.g., 0.1) sharpens the distribution, making the model more likely to select the highest-probability words, resulting in more deterministic and focused outputs. A higher temperature (e.g., 2.0) flattens the distribution, increasing the likelihood of selecting less probable words, thus introducing more randomness and creativity. Option D accurately describes this role. Option A is incorrect because temperature doesn't directly increase accuracy but influences output diversity. Option B is unrelated, as temperature doesn't dictate the number of words generated. Option C is also incorrect, as part-of-speech decisions are not directly tied to temperature but to the model's learned patterns.
General LLM decoding principles, likely covered in OCI 2025 Generative AI documentation under decoding parameters like temperature.
