Oracle Cloud Infrastructure 2025 Generative AI Professional Sample Questions (Q20-Q25):

NEW QUESTION # 20
What distinguishes the Cohere Embed v3 model from its predecessor in the OCI Generative AI service?

A. Emphasis on syntactic clustering of word embeddings
B. Support for tokenizing longer sentences
C. Improved retrievals for Retrieval Augmented Generation (RAG) systems
D. Capacity to translate text in over 100 languages

Answer: C

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Cohere Embed v3, as an advanced embedding model, is designed with improved performance for retrieval tasks, enhancing RAG systems by generating more accurate, contextually rich embeddings. This makes Option B correct. Option A (tokenization) isn't a primary focus-embedding quality is. Option C (syntactic clustering) is too narrow-semantics drives improvement. Option D (translation) isn't an embedding model's role. v3 boosts RAG effectiveness.
OCI 2025 Generative AI documentation likely highlights Embed v3 under supported models or RAG enhancements.

NEW QUESTION # 21
When should you use the T-Few fine-tuning method for training a model?

A. For datasets with hundreds of thousands to millions of samples
B. For datasets with a few thousand samples or less
C. For complicated semantic understanding improvement
D. For models that require their own hosting dedicated AI cluster

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation=
T-Few is ideal for smaller datasets (e.g., a few thousand samples) where full fine-tuning risks overfitting and is computationally wasteful-Option C is correct. Option A (semantic understanding) is too vague-dataset size matters more. Option B (dedicated cluster) isn't a condition for T-Few. Option D (large datasets) favors Vanilla fine-tuning. T-Few excels in low-data scenarios.
OCI 2025 Generative AI documentation likely specifies T-Few use cases under fine-tuning guidelines.

NEW QUESTION # 22
Which statement is true about string prompt templates and their capability regarding variables?

A. They require a minimum of two variables to function properly.
B. They support any number of variables, including the possibility of having none.
C. They can only support a single variable at a time.
D. They are unable to use any variables.

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation=
String prompt templates (e.g., in LangChain) are flexible frameworks that can include zero, one, or multiple variables (placeholders) to customize prompts dynamically. They can be static (no variables) or complex (many variables), making Option C correct. Option A is too restrictive. Option B is false-variables are a core feature. Option D is incorrect, as no minimum is required. This flexibility aids prompt engineering.
OCI 2025 Generative AI documentation likely covers prompt templates under LangChain or prompt design.

NEW QUESTION # 23
How are fine-tuned customer models stored to enable strong data privacy and security in the OCI Generative AI service?

A. Shared among multiple customers for efficiency
B. Stored in Key Management service
C. Stored in Object Storage encrypted by default
D. Stored in an unencrypted form in Object Storage

Answer: C

Explanation:
Comprehensive and Detailed In-Depth Explanation=
In OCI, fine-tuned models are stored in Object Storage, encrypted by default, ensuring privacy and security per cloud best practices-Option B is correct. Option A (shared) violates privacy. Option C (unencrypted) contradicts security standards. Option D (Key Management) stores keys, not models. Encryption protects customer data.
OCI 2025 Generative AI documentation likely details storage security under fine-tuning workflows.

NEW QUESTION # 24
What is the role of temperature in the decoding process of a Large Language Model (LLM)?

A. To decide to which part of speech the next word should belong
B. To determine the number of words to generate in a single decoding step
C. To increase the accuracy of the most likely word in the vocabulary
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.
