The answer is few-shot learning. This technique is correct because the developer provides three labeled examples per category directly in the prompt, enabling the model to classify new tickets by recognizing patterns from those examples without any fine-tuning or weight updates. On the Microsoft Azure AI Fundamentals AI-900 exam, this scenario tests your understanding of in-context learning within Azure OpenAI Service, often appearing as a distractor against zero-shot learning (no examples) or fine-tuning (retraining the model). A common trap is confusing few-shot with one-shot learning, but remember: few-shot uses multiple examples per class, while one-shot uses only one. For the exam, think of the phrase “three examples, no training” to lock in few-shot learning as the correct technique for classification tasks with limited labeled data.
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. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 developer is using Azure OpenAI Service to classify customer support tickets into categories such as 'Billing', 'Technical Issue', and 'Account Management'. The developer provides three labeled examples for each category in the prompt to improve the model's accuracy. What technique is the developer applying?
Why wrong: Fine-tuning involves retraining the model on a custom dataset, which is not what the developer is doing here.
B
Few-shot learning
By providing a few labeled examples in the prompt, the developer is using few-shot learning to guide the model's classification behavior without retraining.
C
Prompt engineering
Why wrong: Prompt engineering is a broader field, but the specific technique of using examples in the prompt is called few-shot learning.
D
Retrieval-augmented generation
Why wrong: Retrieval-augmented generation (RAG) retrieves relevant external information to augment the model's response, not simply including examples in the prompt.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Few-shot learning
Few-shot learning is the correct technique because the developer is providing a small number of labeled examples (three per category) directly in the prompt to guide the model's output without updating the model's weights. This approach leverages the model's in-context learning ability, where the examples act as a pattern for the model to follow when classifying new tickets.
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.
✗
Fine-tuning
Why it's wrong here
Fine-tuning involves retraining the model on a custom dataset, which is not what the developer is doing here.
✓
Few-shot learning
Why this is correct
By providing a few labeled examples in the prompt, the developer is using few-shot learning to guide the model's classification behavior without retraining.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse few-shot learning with fine-tuning, assuming that any use of examples to improve accuracy must involve retraining the model, but few-shot learning does not modify model weights—it only uses examples in the prompt.
Detailed technical explanation
How to think about this question
Few-shot learning in Azure OpenAI Service relies on the model's ability to generalize from a handful of examples provided in the context window, using the transformer's attention mechanism to infer the mapping between inputs and outputs. The number of examples (here, three per category) is critical because too few may not establish a clear pattern, while too many can exceed the token limit or cause the model to overfit to the examples. In practice, this technique is often used for tasks like text classification or entity extraction where labeled data is scarce, but it requires careful selection of diverse and representative examples to avoid bias.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
