Question 521 of 1,020

Quick Answer

The answer is temperature, and decreasing it is the correct parameter to make Azure OpenAI output more predictable. Temperature controls the randomness of token selection; a lower value, such as 0.2, forces the model to choose the most probable next words, producing conservative, common phrases and reducing surprising or unusual combinations. On the AI-900 exam, this concept tests your understanding of how to tune generative AI for specific business needs—here, a marketing team wanting reliable taglines. A common trap is confusing temperature with top-p (nucleus sampling), which also limits randomness but works differently by cutting off low-probability tokens entirely. Remember: lower temperature = less creativity, more predictability; think of it as turning down the “surprise dial” to get safe, expected outputs.

AI-900 Practice Question: Describe features of generative AI workloads on Azure

This AI-900 practice question tests your understanding of describe features of generative ai workloads on azure. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 marketing team uses Azure OpenAI Service to generate taglines for a new advertising campaign. They want the output to be more predictable and less surprising, sticking to the most common phrases and avoiding unusual combinations. Which parameter should they decrease?

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

Temperature

Temperature controls the randomness of the model's output. Lowering the temperature (e.g., from 1.0 to 0.2) makes the model more deterministic, favoring high-probability tokens and common phrases, which reduces surprise and unusual combinations. This directly aligns with the team's goal of predictable, conservative taglines.

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.

  • Temperature

    Why this is correct

    Correct because decreasing temperature makes the model less random and more deterministic, favoring the most likely tokens and producing more predictable output.

  • Top P

    Why it's wrong here

    Incorrect because decreasing top_p can also reduce randomness by limiting the sampling pool to the most likely tokens with a cumulative probability threshold, but it is not the primary control; temperature directly affects the probability distribution's sharpness.

  • Frequency penalty

    Why it's wrong here

    Incorrect because frequency penalty reduces the likelihood of repeating the same tokens in the generated text; it does not control the overall randomness or predictability of the output.

  • Presence penalty

    Why it's wrong here

    Incorrect because presence penalty encourages the model to talk about new topics by penalizing tokens that have already appeared; it does not directly control how predictable or surprising the output is.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse Top P with temperature, thinking both control randomness equally, but Top P controls the size of the candidate set while temperature directly scales token probabilities, making temperature the correct choice for reducing surprise and sticking to common phrases.

Trap categories for this question

  • Command / output trap

    Incorrect because frequency penalty reduces the likelihood of repeating the same tokens in the generated text; it does not control the overall randomness or predictability of the output.

Detailed technical explanation

How to think about this question

Under the hood, temperature scales the logits (raw scores) before the softmax function: dividing by a lower temperature amplifies differences between high and low probability tokens, making the model more confident and repetitive. In contrast, Top P dynamically adjusts the vocabulary set per generation step, which can interact with temperature in complex ways; for strictly predictable outputs, lowering temperature alone is the standard approach. A real-world scenario is generating legal disclaimers where every word must be precise and avoid creative variation.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
