- A
Set temperature to 0.
Why wrong: Temperature 0 makes the model deterministic, always picking the most likely token, which reduces creativity and variety.
- B
Increase the temperature parameter.
Higher temperature increases randomness, leading to more creative and varied text generation.
- C
Decrease the temperature parameter.
Why wrong: Decreasing temperature makes the model more conservative and repetitive, reducing creativity.
- D
Increase the max_tokens parameter.
Why wrong: Max_tokens controls response length, not creativity. Longer responses may still be repetitive if temperature is low.
Quick Answer
The answer is to increase the temperature parameter. This works because temperature controls the randomness of token sampling in the model’s probability distribution; a higher temperature, typically between 0.7 and 1.0, flattens the distribution, making less likely tokens more probable and thus producing more diverse and imaginative text. On the Oracle Cloud Infrastructure Generative AI Professional 1Z0-1127 exam, this question tests your understanding of how to steer generative output for specific use cases—here, the need for creative marketing copy. A common trap is confusing temperature with top-p or top-k sampling, but remember that temperature directly affects randomness, while the others control the pool of candidate tokens. For a memory tip, think of temperature like a creativity dial: turn it up for wild ideas, keep it low for safe, predictable answers.
1Z0-1127 Fundamentals of Large Language Models Practice Question
This 1Z0-1127 practice question tests your understanding of fundamentals of large language models. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A user wants to use OCI Generative AI to generate marketing copy. They want the output to be more creative and varied. Which parameter should they adjust?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Increase the temperature parameter.
Increasing the temperature parameter makes the model's output more random and diverse, which is ideal for creative tasks like generating marketing copy. A higher temperature (e.g., 0.7–1.0) increases the probability of sampling less likely tokens, leading to more varied and imaginative text. Setting temperature to 0 would make the output deterministic and repetitive, which is the opposite of what the user wants.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set temperature to 0.
Why it's wrong here
Temperature 0 makes the model deterministic, always picking the most likely token, which reduces creativity and variety.
- ✓
Increase the temperature parameter.
Why this is correct
Higher temperature increases randomness, leading to more creative and varied text generation.

- ✗
Decrease the temperature parameter.
Why it's wrong here
Decreasing temperature makes the model more conservative and repetitive, reducing creativity.
- ✗
Increase the max_tokens parameter.
Why it's wrong here
Max_tokens controls response length, not creativity. Longer responses may still be repetitive if temperature is low.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Oracle often tests the misconception that increasing max_tokens or adjusting other parameters like top_p can substitute for temperature when the goal is to increase creativity, but only temperature directly controls randomness and diversity in token selection.
Detailed technical explanation
How to think about this question
Temperature controls the softmax distribution over the vocabulary: a higher temperature flattens the probability curve, giving lower-probability tokens a greater chance of being selected. This is implemented by dividing the logits by the temperature value before applying softmax. In practice, for marketing copy generation, a temperature around 0.8–1.0 is often used to balance coherence with creativity, while values above 1.0 can lead to incoherent or nonsensical output.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
