Question # 1

Given 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 # 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

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

B. "Top p" assigns penalties to frequently occurring tokens.
C. "Top p" limits token selection based on the sum of their probabilities.
D. "Top p" determines the maximum number of tokens per response.
