Google Cloud Professional Machine Learning Engineer (PMLE) Exam Guide

Validates skills in building, deploying, automating and monitoring machine learning and generative AI solutions on Google Cloud.

The exam tests how you build, scale, serve, automate and monitor ML and generative AI solutions on Google Cloud. Learn where BigQuery ML, AutoML, custom training and Model Garden each fit, practise the MLOps flow on Agent Platform, then drill scenario questions that ask for the most Google Cloud native answer.

Understand the exam

Syllabus

Section 1Architecting low-code AI solutions13%
  1. 1.1Developing ML models using BigQuery ML or AutoML on Gemini Enterprise Agent Platform
  2. 1.2Building AI solutions using Google Cloud AI APIs or foundational models

Example scenario: A retailer wants weekly demand forecasts from sales data already in BigQuery, with no ML engineers on the team. Which approach would you suggest first?

Section 2Collaborating within and across teams to manage data and models16%
  1. 2.1Exploring and preprocessing data for ML
  2. 2.2Model prototyping using notebooks
  3. 2.3Tracking and running ML experiments

Example scenario: Two teams train similar churn models and cannot tell which features and data versions produced the best one. What would you put in place?

Section 3Scaling prototypes into ML models21%
  1. 3.1Building models given the task considering cost, complexity, latency, and scalability
  2. 3.2Training models
  3. 3.3Choosing appropriate hardware for training

Example scenario: A large image model trains too slowly on one GPU and the dataset keeps growing. What options would you compare to speed it up?

Section 4Serving and scaling models20%
  1. 4.1Serving models
  2. 4.2Scaling online model serving

Example scenario: A new fraud model looks better offline, but the team is nervous about switching all traffic. How would you roll it out?

Section 5Automating and orchestrating ML pipelines18%
  1. 5.1Developing end-to-end ML pipelines
  2. 5.2Automating model retraining

Example scenario: A model's accuracy drops each quarter as customer behaviour changes. How would you automate retraining and safe redeployment?

Section 6Monitoring AI solutions13%
  1. 6.1Identifying risks to AI solutions
  2. 6.2Monitoring, testing, and troubleshooting AI solutions

Example scenario: A support chatbot sometimes repeats customer account numbers from its context. What controls would you add?

Question types

Choose the one correct answer from the options.

CertUp example

A team's model sees different feature calculations in training than in production serving. What is the best way to keep them consistent?

  1. Compute and serve the features from a shared feature store
  2. Write separate feature code for training and serving
  3. Recompute features by hand before each prediction
  4. Drop the features that differ
Show answer

Compute and serve the features from a shared feature store. The same definitions are then used for training and serving, which avoids training-serving skew.

Eligibility and booking

Create a CM Connect account, choose the exam and delivery method, then pick a Pearson VUE time and pay. Your CM Connect legal name must match your ID exactly.

Make a study plan

Read the June 2026 guide and try the sample questions, then follow one course with labs. Make sure your materials use Agent Platform names and cover the newer generative AI topics.

Most candidates spend 60–120 hours. Plan for the low end if you already run ML on Google Cloud; add time if you are new to Google Cloud or to ML.

Learn the core concepts

Use Google's learning path or another course updated for the June 2026 guide. Older books and courses still help with ML fundamentals.

Learn the decision points. For each scenario, decide between prompt engineering, RAG and fine-tuning, and between BigQuery ML, AutoML and custom training, before you look at the options.

Practice with mock exams

Start with Google's sample questions. Many question banks still use older Vertex AI names, so check that a set covers the June 2026 topics before relying on it.

Are you ready?

  • You can choose between BigQuery ML, AutoML, custom training and Model Garden models for a scenario.
  • You can explain how to detect and respond to training-serving skew and drift.
  • You finish a fresh timed test and can explain each wrong answer.

Prepare for exam day

Choose the checklist for your test centre or online appointment.

Before going to the test centre

  • Bring two IDs. One must be a government photo ID with your signature; the second must show your name and signature.
  • Check that your CM Connect legal name matches your ID exactly. A mismatch means no exam and a lost fee.
  • Arrive at least 15 minutes early and expect to store personal items in a locker.
  • No food or drink is allowed in the testing room.
Find a Pearson VUE test centre

Reschedule or cancel at least 24 hours ahead to avoid a late fee. After a fail, wait 14 days, then 60 days, then a year; you get up to four attempts in two years.

Advice from exam takers

Check what the June 2026 update added.

A course creator answering a candidate said the Vertex AI to Agent Platform change is mostly naming, but the update added topics such as choosing between prompting, RAG and tuning, Model Armor, LLM evaluation methods and Agent Search versus Vector Search. Another candidate found most question banks had not caught up.
