2026 Google Cloud PMLE & PDE Exam Guides: What They Emphasize
The current Professional Machine Learning Engineer (PMLE) and Professional Data Engineer (PDE) exam guides place heavy emphasis on generative AI — including RAG, foundation models, LLM evaluation, and AI-powered data enrichment. This page documents the current objectives, weights, and key GenAI topics from the official PMLE guide and official PDE guide.
PMLE — Professional Machine Learning Engineer
Key GenAI emphasis in the current guide
- Generative AI throughout: The role explicitly includes "designs and operationalizes generative AI solutions based on foundation models."
- Model Garden + Agent Builder: RAG applications via Vertex AI Agent Builder and foundation model selection from Model Garden.
- Evaluation: Evaluating generative AI solutions is a named subtopic (2.3).
- Fine-tuning: Fine-tuning foundation models via Vertex AI and Model Garden (3.2).
Current Structure (June 2026)

| Section | Objective | Weight |
|---|---|---|
| 1 | Architecting low-code AI solutions | ~13% |
| 2 | Collaborating within and across teams to manage data and models | ~14% |
| 3 | Scaling prototypes into ML models | ~18% |
| 4 | Serving and scaling models | ~20% |
| 5 | Automating and orchestrating ML pipelines | ~22% |
| 6 | Monitoring AI solutions | ~13% |
GenAI Topics Covered
PDE — Professional Data Engineer
Key GenAI emphasis in the current guide
- GenAI in the pipeline: LLM prompting for query generation and AI data enrichment.
- RAG data prep: Preparing unstructured data for embeddings and retrieval-augmented generation.
- Modern governance: Dataplex + Dataplex Catalog for federated governance (data-mesh).
- Sharing model: BigQuery sharing via Analytics Hub.
- Capacity management: BigQuery Editions & reservations.
- Renewal exam: A shorter renewal option focused on recent services is available alongside the full exam.
