Google renamed the platform this exam is built on. Vertex AI is now the Gemini Enterprise Agent Platform, and the exam guide uses the new names throughout Agent Platform AutoML, Model Garden, Feature Store, Workbench, Pipelines, Model Registry, Inference, Model Monitoring. Most prep material still says Vertex AI. This is the complete bank, rewritten against the current guide. "Vertex AI" appears nowhere in it. 150 questions, balanced to the real exam weightings Architecting low-code AI solutions: BigQuery ML, Agent Platform AutoML, selecting from Model Garden, the industry APIs, optimising Gemini applications for cost and latency, fine-tuning Gemini models in BigQuery Collaborating to manage data and models: Feature Store, Workbench and Colab Enterprise, Experiments, ML Metadata and lineage, PII handling, choosing preprocessing tools by scale Scaling prototypes into ML models: custom training, Tabular Workflows, Kubeflow on GKE, hyperparameter tuning, CPU/GPU/TPU selection, data versus model parallelism, fine-tuning foundation models Serving and scaling models: batch versus online inference, Model Registry, prebuilt and custom containers, canary and A/B rollouts, public and private endpoints, autoscaling, edge inference Automating and orchestrating ML pipelines: Agent Platform Pipelines, Managed Service for Apache Airflow, Ray on Agent Platform, Cloud Build, CI/CD/CT, retraining policy, data and model validation gates. Monitoring AI solutions: data drift, concept drift, training-serving skew, feature attribution drift, Model Armor, safety filters, explainability, monitoring for bias Every option explained, not just the right one Each question tells you why the correct answer is correct and why each distractor is wrong. On an exam where several options are plausible, knowing why the near-miss fails is most of the skill and it is what separates a question bank from a flashcard. Nothing here is out of date Beyond the platform rename, this release adds the material the current guide introduced: Model Armor for defending against malicious prompting and data exfiltration, LLM-as-a-judge for evaluating generative solutions where there is no single correct output, Colab Enterprise, Managed Service for Apache Airflow, and Ray on Agent Platform. Built for flights Everything ships inside the app. Nothing is fetched, nothing streams, nothing checks an account on launch โ€” airplane mode, the subway and a dead-zone basement all behave exactly the same as full signal. A long flight is 150 questions of study time you already have with you. Also included Exam Pace Timer: an optional, non-enforced countdown that mirrors real exam pacing. It never locks you out and never auto-submits. Daily study reminder, if you want one. Scheduled on your device; nothing is sent from a server. Progress tracking: streaks, best scores and full attempt history, stored on your device. No account, no sign-up, no ads, no subscription.
