• Question 65:

  How does a presence penalty function in language model generation?

  A. It penalizes all tokens equally, regardless of how often they have appeared.
  B. It penalizes only tokens that have never appeared in the text before.
  C. It applies a penalty only if the token has appeared more than twice.
  D. It penalizes a token each time it appears after the first occurrence.
  D. It penalizes a token each time it appears after the first occurrence.

• Question 66:

  Given the following prompts used with a Large Language Model, classify each as employing the Chain-of-Thought, Least-to-Most, or Step-Back prompting technique:

  Example A: "Calculate the total number of wheels needed for 3 cars. Cars have 4 wheels each. Then, use the total number of wheels to determine how many sets of wheels we can buy with $200 if one set (4 wheels) costs $50."

  Example B: "Solve a complex math problem by first identifying the formula needed, and then solve a simpler version of the problem before tackling the full question."

  Example C: "To understand the impact of greenhouse gases on climate change, let's start by defining what greenhouse gases are. Next, we'll explore how they trap heat in the Earth's atmosphere."

  A. 1: Step-Back, 2: Chain-of-Thought, 3: Least-to-Most"
  B. 1: Least-to-Most, 2: Chain-of-Thought, 3: Step-Back

• Question 67:

  What is the purpose of the "stop sequence" parameter in the OCI Generative AI Generation models?

  A. It specifies a string that tells the model to stop generating more content.
  B. It assigns a penalty to frequently occurring tokens to reduce repetitive text.
  C. It determines the maximum number of tokens the model can generate per response.
  D. It controls the randomness of the model's output, affecting its creativity.
  A. It specifies a string that tells the model to stop generating more content.

• Question 68:
