AI-900 Practice Question: Describe Artificial Intelligence workloads and considerations
Which of the following is an example of an AI workload that uses prediction?
⚠ Common exam trap
It's easy for candidates to 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.

Correct answer & explanation
✓
Predicting equipment failure based on sensor data
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.

- ✗
Displaying a list of items in alphabetical order
Why it's wrong here
Displaying items in alphabetical order relies on a deterministic sorting algorithm (e.g., quicksort or merge sort) that compares strings character by character according to a collation sequence. The exact output is guaranteed by the input and the comparison logic, with no probabilistic model, no training data, and no ability to generalize to unseen situations. It is an algorithmic data operation, not an AI prediction workload.
- ✓
Predicting equipment failure based on sensor data
Why this is correct
Predicting equipment failure from sensor data is a classic AI prediction workload because a machine learning model is trained on historical telemetry (e.g., temperature, vibration, pressure) labeled with known failure events. The model discovers patterns and correlations that precede failures, then uses new sensor readings to output a probability or remaining useful life estimate. This is supervised learning and predictive maintenance, a textbook Azure AI scenario.
- ✗
Storing customer records in a database
Why it's wrong here
Storing customer records in a database is a data persistence task performed by a database management system using CRUD operations (create, read, update, delete). The system organizes rows and columns, indexes fields, and retrieves data by exact or query-based matching, but it never predicts a future state or learns patterns from the data. Even when the database supports triggers or stored procedures, those are preprogrammed rules, not machine learning inference.
- ✗
Formatting text documents
Why it's wrong here
Formatting text documents applies predetermined style, layout, and font rules inside a word processor; it is a deterministic transformation, not an AI prediction workload. No model is trained on historical data, and no probabilistic inference is made about future outcomes. The result depends solely on the document's current content and the chosen formatting rules, so it lacks the learning and generalization that define AI workloads.
