The correct answer is predicting equipment failure based on sensor data. This is a classic example of a prediction AI workload because it uses historical sensor readings—such as temperature, vibration, and pressure—to train a machine learning model that forecasts a future outcome, specifically when equipment is likely to fail, enabling proactive maintenance. On the Microsoft Azure AI Fundamentals AI-900 exam, this scenario tests your understanding of how prediction workloads differ from other AI categories like classification or anomaly detection; a common trap is confusing prediction with real-time anomaly detection, but prediction specifically outputs a future probability or time-based forecast. To remember this, think of the mnemonic “Sensors Predict Future Failures”—if the model uses past data to answer “what will happen next,” it’s a prediction workload.
AI-900 Practice Question: Describe Artificial Intelligence workloads and considerations

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.
Which of the following is an example of an AI workload that uses prediction?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Predicting equipment failure based on sensor data
Option B is correct because predicting equipment failure based on sensor data is a classic example of a predictive AI workload. It uses historical sensor data (e.g., temperature, vibration, pressure) to train a machine learning model that forecasts when equipment is likely to fail, enabling proactive maintenance. This falls under the AI workload category of prediction, where the model outputs a future outcome or probability.
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.
✗
Displaying a list of items in alphabetical order
Why it's wrong here
Alphabetical sorting is a deterministic algorithm — no prediction or AI involved.
✓
Predicting equipment failure based on sensor data
Why this is correct
Predictive maintenance uses ML models to learn patterns in sensor data and predict failures before they occur — a classic AI prediction workload.

✗
Storing customer records in a database
Why it's wrong here
Database storage is traditional computing — no AI prediction involved.
✗
Formatting text documents
Why it's wrong here
Text formatting is rule-based processing — not an AI prediction workload.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse simple data processing or rule-based automation (like sorting or formatting) with AI workloads, but AI specifically requires learning from data to make predictions or decisions without explicit programming for every scenario.
Detailed technical explanation
How to think about this question
Predictive maintenance models often use regression or classification algorithms (e.g., Random Forest, LSTM) trained on time-series sensor data. The model learns patterns that precede failures, such as increasing vibration amplitude or temperature spikes, and outputs a probability or time-to-failure estimate. In Azure, this can be implemented using Azure Machine Learning with automated ML or Azure IoT Edge for real-time inference at the edge.

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.
