Oracle Cloud Infrastructure 2025 Generative AI Professional Sample Questions (Q70-Q75):

NEW QUESTION # 70
What does the Ranker do in a text generation system?

A. It generates the final text based on the user's query.
B. It evaluates and prioritizes the information retrieved by the Retriever.
C. It interacts with the user to understand the query better.
D. It sources information from databases to use in text generation.

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation=
In systems like RAG, the Ranker evaluates and sorts the information retrieved by the Retriever (e.g., documents or snippets) based on relevance to the query, ensuring the most pertinent data is passed to the Generator. This makes Option C correct. Option A is the Generator's role. Option B describes the Retriever. Option D is unrelated, as the Ranker doesn't interact with users but processes retrieved data. The Ranker enhances output quality by prioritizing relevant content.
OCI 2025 Generative AI documentation likely details the Ranker under RAG pipeline components.

NEW QUESTION # 71
Which is a cost-related benefit of using vector databases with Large Language Models (LLMs)?

A. They are more expensive but provide higher quality data.
B. They offer real-time updated knowledge bases and are cheaper than fine-tuned LLMs.
C. They require frequent manual updates, which increase operational costs.
D. They increase the cost due to the need for real-time updates.

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Vector databases enable real-time knowledge retrieval for LLMs (e.g., in RAG), avoiding the high computational and data costs of fine-tuning an LLM for every update. They store embeddings efficiently, making them a cost-effective alternative to retraining, thus Option B is correct. Option A is false-updates are automated, not manual. Option C misrepresents-real-time capability reduces, not increases, costs compared to fine-tuning. Option D is incorrect-vector databases aren't inherently more expensive; they optimize cost and performance. This makes them economical for dynamic applications.
OCI 2025 Generative AI documentation likely highlights vector database cost benefits under RAG or data management sections.

NEW QUESTION # 72
What is the main advantage of using few-shot model prompting to customize a Large Language Model (LLM)?

A. It eliminates the need for any training or computational resources.
B. It allows the LLM to access a larger dataset.
C. It significantly reduces the latency for each model request.
D. It provides examples in the prompt to guide the LLM to better performance with no training cost.

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation=
Few-shot prompting involves providing a few examples in the prompt to guide the LLM's behavior, leveraging its in-context learning ability without requiring retraining or additional computational resources. This makes Option C correct. Option A is false, as few-shot prompting doesn't expand the dataset. Option B overstates the case, as inference still requires resources. Option D is incorrect, as latency isn't significantly affected by few-shot prompting.
OCI 2025 Generative AI documentation likely highlights few-shot prompting in sections on efficient customization.

NEW QUESTION # 73
Given the following code:
PromptTemplate(input_variables=["human_input", "city"], template=template) Which statement is true about PromptTemplate in relation to input_variables?

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

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation=
In LangChain, PromptTemplate supports any number of input_variables (zero, one, or more), allowing flexible prompt design-Option C is correct. The example shows two, but it's not a requirement. Option A (minimum two) is false-no such limit exists. Option B (single variable) is too restrictive. Option D (no variables) contradicts its purpose-variables are optional but supported. This adaptability aids prompt engineering.
OCI 2025 Generative AI documentation likely covers PromptTemplate under LangChain prompt design.

NEW QUESTION # 74
What happens if a period (.) is used as a stop sequence in text generation?

A. The model stops generating text after it reaches the end of the current paragraph.
B. The model ignores periods and continues generating text until it reaches the token limit.
C. The model generates additional sentences to complete the paragraph.
D. The model stops generating text after it reaches the end of the first sentence, even if the token limit is much higher.

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation=
A stop sequence in text generation (e.g., a period) instructs the model to halt generation once it encounters that token, regardless of the token limit. If set to a period, the model stops after the first sentence ends, making Option D correct. Option A is false, as stop sequences are enforced. Option B contradicts the stop sequence's purpose. Option C is incorrect, as it stops at the sentence level, not paragraph.
OCI 2025 Generative AI documentation likely explains stop sequences under text generation parameters.
