Oracle 1Z0-1127-25 Sample Question Answers
Question # 1Given the following prompts used with a Large Language Model, classify
A. "Calculate the total number of wheels needed for 3 cars. Cars have 4 wheels each. Then, use thetotal number of wheels to determine how many sets of wheels we can buy with $200 if one set (4 wheels) costs $50."
B. "Solve a complex math problem by first identifying the formula needed, and then solve a simplerversion of the problem before tackling the full question."
C. "To understand the impact of greenhouse gases on climate change, let's start by defining whatgreenhouse gases are. Next, we'll explore how they trap heat in the Earth's atmosphere."A. 1: StepBack, 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
Question # 2
Which is a distinguishing feature of "Parameter-Efficient Fine-Tuning (PEFT)" as opposed to classic "Fine-tuning" in Large Language Model training?
A. PEFT involves only a few or new parameters and uses labeled, task-specific data.
B. PEFT modifies all parameters and is typically used when no training data exists.
C. PEFT does not modify any parameters but uses soft prompting with unlabeled data.
D. PEFT modifies all parameters and uses unlabeled, task-agnostic data.
Question # 3
You create a fine-tuning dedicated AI cluster to customize a foundational model with your customtraining data. How many unit hours are required for fine-tuning if the cluster is active for 10 hours?
A. 25 unit hours
B. 40 unit hours
C. 20 unit hours
D. 30 unit hours
Question # 4
Which statement describes the difference between "Top k" and "Top p" in selecting the next token in the OCI Generative AI Generation models?
A. "Top k" and "Top p" are identical in their approach to token selection but differ in their applicationof penalties to tokens.
B. "Top k" selects the next token based on its position in the list of probable tokens, whereas "Top p"selects based on the cumulative probability of the top tokens.
C. "Top k" considers the sum of probabilities of the top tokens, whereas "Top p" selects from the "Topk" tokens sorted by probability.
D. "Top k" and "Top p" both select from the same set of tokens but use different methods to prioritizethem based on frequency
Question # 5
Which role does a "model endpoint" serve in the inference workflow of the OCI Generative AI service?
A. Updates the weights of the base model during the fine-tuning process
B. Serves as a designated point for user requests and model responses
C. Evaluates the performance metrics of the custom models
D. Hosts the training data for fine-tuning custom models
Question # 6
Which component of Retrieval-Augmented Generation (RAG) evaluates and prioritizes theinformation retrieved by the retrieval system?
A. Retriever
B. Encoder-Decoder
C. Generator
D. Ranker
Question # 7
What is the primary function of the "temperature" parameter in the OCI Generative AI Generation models?
A. Controls the randomness of the model's output, affecting its creativity
B. Specifies a string that tells the model to stop generating more content
C. Assigns a penalty to tokens that have already appeared in the preceding text
D. Determines the maximum number of tokens the model can generate per response
Question # 8
Which is NOT a built-in memory type in LangChain?
A. ConversationImageMemory
B. ConversationBufferMemory
C. ConversationSummaryMemory
D. ConversationTokenBufferMemory
Question # 9
Given the following code:chain = prompt | llmWhich statement is true about LangChain Expression Language (LCEL)?
A. LCEL is a programming language used to write documentation for LangChain.
B. LCEL is a legacy method for creating chains in LangChain.
C. LCEL is a declarative and preferred way to compose chains together.
D. LCEL is an older Python library for building Large Language Models.
