Quick Answer
The answer is regression, classification, and time-series forecasting. BigQuery ML supports these three supervised output types through distinct model architectures: `LINEAR_REG` for regression tasks predicting continuous values, `LOGISTIC_REG` for classification problems outputting discrete labels or probabilities, and `ARIMA_PLUS` for time-series forecasting that predicts future data points based on historical patterns. On the Google Professional Machine Learning Engineer exam, this concept tests your understanding of how BigQuery ML abstracts traditional ML workflows into SQL, with a common trap being the assumption that clustering or unsupervised methods are supported as primary output types—they are not, as BigQuery ML focuses on supervised and forecasting tasks. A useful memory tip is to think of the three core business problems: "How much?" (regression), "Which category?" (classification), and "What's next?" (forecasting).
This PMLE practice question tests your understanding of architecting low-code ml solutions. 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 THREE of the following are supported output types for BigQuery ML?
Classification
e.g., logistic regression model.
Object detection
Why wrong: Not supported.
Anomaly detection
Why wrong: Not an official model type.
Time-series forecasting
e.g., ARIMA model.
Regression
e.g., linear regression model.

Correct answer & explanation
Classification
BigQuery ML supports supervised learning tasks like classification and regression, as well as time-series forecasting, through its model types such as `LOGISTIC_REG`, `LINEAR_REG`, and `ARIMA_PLUS`. Classification (option A) is correct because BigQuery ML provides `LOGISTIC_REG` for binary and multi-class classification problems, outputting predicted labels or probabilities.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Google Cloud often tests the distinction between supported BigQuery ML output types and broader ML capabilities, leading candidates to mistakenly include object detection or anomaly detection, which are not native output types in BigQuery ML's SQL-based interface.
Detailed technical explanation
BigQuery ML leverages SQL-based model creation and inference, with supported model types including `LINEAR_REG` for regression, `LOGISTIC_REG` for classification, and `ARIMA_PLUS` for time-series forecasting. Under the hood, these models are trained using distributed TensorFlow or XGBoost, and outputs are generated as SQL query results, making it easy to integrate with existing data pipelines. A real-world scenario is predicting customer churn (classification) or sales trends (forecasting) directly within BigQuery without moving data.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
