About the PMLE exam
Google Cloud Certified Professional Machine Learning Engineer (PMLE) is the exam for the Google Cloud Professional Machine Learning Engineer certification. In April 2026 Google renamed Vertex AI to Gemini Enterprise Agent Platform. The exam guide still uses the Vertex AI names, so this pack uses them too. Our guide follows the official exam outline dated November 2026 (exam guide version 3.1).
| Length | Two hours |
| Questions | 50 to 60 multiple choice and multiple select |
| Registration fee | $200 (plus tax where applicable) |
| Recommended experience | 3+ years, including 1+ year on Google Cloud |

A grocery chain keeps three years of daily sales for 400 stores in a BigQuery table. Analysts who know SQL want a separate 30 day sales forecast for every store, with holiday effects, without moving data out of BigQuery. What should they build?
Correct answer: B
ARIMA_PLUS is the BigQuery ML time series model. Setting a time series ID column trains one forecast per store in a single statement, and it can model holiday effects. ML.FORECAST then returns the future values.
A data science team wants managed notebooks with no VMs to create or patch. Platform admins must control machine types and network settings through shared templates, and notebooks should be easy to open next to BigQuery data. Which option fits best?
Correct answer: D
Colab Enterprise is a managed notebook service with no instances for users to manage. Admins define runtime templates for machine type and network, and it integrates with BigQuery Studio.
A bank must explain every credit decision to regulators by showing exactly how each input moves the score. Accuracy only needs to be close to the current scorecard. Which modeling approach should you choose?
Correct answer: A
When interpretability is a hard requirement, an inherently interpretable model is the safest choice. Each logistic regression coefficient shows the direction and size of a feature effect.
Every night you must score 60 million customer rows stored in BigQuery with a custom model registered in Vertex AI Model Registry. No one needs results before morning, and you want to avoid paying for idle serving nodes. What should you use?
Correct answer: C
Batch prediction runs against the model without deploying it to an endpoint. Nodes start for the job and stop when it ends, and BigQuery can be both the input and the output.
A model performed well in testing but poorly in production. You find that the training code scaled numeric features with Python, while the serving app reimplemented the scaling in Java with slightly different logic. How do you prevent this in future?
Correct answer: B
TensorFlow Transform saves the preprocessing as a graph that is attached to the exported model, so exactly the same logic runs in training and serving. BigQuery ML TRANSFORM gives the same benefit for BigQuery ML models.
