Practice for the Professional Machine Learning Engineer exam with questions written to the current exam guide, which renamed the platform it covers: Vertex AI is now the Gemini Enterprise Agent Platform. Most prep material still uses the old names. This bank uses the new ones throughout. 100 PRACTICE QUESTIONS INCLUDED, 150 WITH THE UNLOCK The app includes 100 questions across all six exam domains. A one-time in-app purchase unlocks the full bank of 150 questions. Your progress and history are kept. ALL SIX EXAM DOMAINS - Architecting low-code AI solutions: BigQuery ML, Agent Platform AutoML, Model Garden, the industry APIs - Collaborating to manage data and models: Feature Store, Workbench, Colab Enterprise, Experiments, ML Metadata - Scaling prototypes: custom training, hyperparameter tuning, TPUs and GPUs, data versus model parallelism, fine-tuning foundation models - Serving and scaling: batch versus online inference, Model Registry, custom containers, canary and A/B rollouts, private endpoints - Automating and orchestrating: Agent Platform Pipelines, Managed Service for Apache Airflow, Ray, CI/CD/CT - Monitoring: data drift, concept drift, training-serving skew, feature attribution drift, Model Armor, responsible AI EVERY OPTION EXPLAINED, NOT JUST THE RIGHT ONE Each question explains why the correct answer is correct and why each distractor is wrong. When several options look plausible, knowing why the near-miss fails is most of the skill. WRITTEN TO THE REAL WEIGHTINGS The exam guide weights its six sections from 13% to 21%. The bank is balanced to match, so your practice time lands where the exam spends its questions. WORKS OFFLINE Everything ships inside the app. Nothing streams and there is no account, so it works the same in airplane mode as on full signal. ALSO INCLUDED - Exam Pace Timer: an optional countdown that never locks you out or auto-submits. - Daily study reminder, if you want one, scheduled on your device. - Progress tracking: streaks, best scores and full history, stored on your device. - No account, no sign-up, no ads.
