This module gives you the baseline AI and data language needed for Databricks Certified Generative AI Engineer Associate. The goal is not to become a research scientist. The goal is to read an official learning or assessment scenario and know which concept is being tested.
Core Concepts To Know
- AI versus ML versus GenAI. AI is the broad goal of useful machine behavior. ML learns patterns from data. GenAI creates or transforms content such as text, code, images, audio, or structured summaries.
- Training versus inference. Training builds or adapts behavior from data. Inference uses a trained model to produce an output for a new input.
- Prediction versus generation. Prediction chooses a label, score, class, or forecast. Generation creates new content and must be checked for grounding, safety, and quality.
- Foundation model. A large pretrained model that can be adapted through prompting, retrieval, fine-tuning, tools, or workflow design.
- Embedding. A numeric representation of meaning that helps search, clustering, recommendations, semantic similarity, and RAG.
- Evaluation. The discipline of measuring whether outputs are correct, useful, safe, fair, and stable enough for the use case.
Data Foundations
Most AI failures start with data assumptions. For Databricks scenarios, ask where the data comes from, who is allowed to use it, whether it is current, whether labels are reliable, and whether sensitive information is protected.
| Data issue | Why it is tested | Self-learner check |
|---|---|---|
| Missing or stale data | The model may answer confidently from incomplete evidence. | Ask whether retrieval, refresh, or data validation is needed. |
| Biased or unrepresentative data | The output can treat groups or edge cases unfairly. | Look for fairness testing, representative samples, and human review. |
| Sensitive data | Prompts, files, logs, and model outputs can expose private or regulated information. | Apply classification, access control, encryption, masking, and retention limits. |
| Poor labels or definitions | A model cannot learn or evaluate a target that the organization has not defined clearly. | Define success metrics before choosing the model or tool. |
Model And Workflow Vocabulary
- Prompting: giving the model a task, context, constraints, examples, and desired output format.
- Grounding: connecting the model to trusted source material so outputs are tied to current facts.
- RAG: retrieving relevant content and passing it to the model at response time, often better than fine-tuning when source material changes frequently.
- Fine-tuning: adapting a model with training examples, useful for repeatable style or task behavior but not a replacement for current source retrieval.
- Agents: systems that plan or call tools to complete tasks; they need boundaries, permissions, logs, and fallback behavior.
- Human oversight: review by a person when the output affects safety, money, legal rights, employment, healthcare, education, or other high-impact decisions.
Provider-Specific Lens
For Databricks Certified Generative AI Engineer Associate, tie every AI concept back to lakehouse AI, ML engineering, generative AI, context engineering, and data governance. A generic definition is useful only if you can apply it to a scenario from Databricks.
- Unity Catalog
- MLflow
- Model Serving
- Vector Search
- Mosaic AI
- Lakehouse monitoring
Track-Specific Vocabulary Priorities
- Read the exact credential title first. Many AI credentials are role-based, so the same AI concept can be tested differently for an engineer, architect, auditor, business leader, teacher, or administrator.
- Translate every objective into a real scenario with a user, data source, risk constraint, and expected output.
- Separate durable AI principles from provider product names so you can still reason when a product name changes.
- Understand prompts, tokens, context windows, embeddings, semantic search, RAG, fine-tuning, tool use, guardrails, and evaluations.
- Choose RAG when answers must reflect current governed sources; choose fine-tuning only when the scenario needs learned behavior or style from examples.
- Evaluate generated outputs for correctness, relevance, source coverage, toxicity, privacy, and refusal behavior.
Example: RAG Or Fine-Tuning
Scenario: a support team needs answers from policy documents that change every month. The best first pattern is usually retrieval-grounded generation because the answer should come from current documents. Fine-tuning may help style or task behavior, but it does not automatically keep the model synchronized with the latest policy.
Common trap: choosing the more advanced-sounding option instead of the pattern that matches the data-change requirement.
Practice Routine
- Make flashcards for the vocabulary above, but put the definition on one side and a workplace example on the other.
- For every provider tool you study, write the AI concept it maps to: search, classification, generation, orchestration, monitoring, governance, or security.
- When you miss a question, classify the miss as vocabulary, data, model choice, security, or operations. Review the category, not just that one answer.
