Domain checklist

Domain	Weight	What to know	Common trap
Databricks Intelligence Platform	10%	workspaces, compute, SQL warehouses, notebooks, catalogs, schemas, tables	treating every task as generic Spark instead of Databricks platform work
Development and Ingestion	17%	Auto Loader, file formats, stages, tables, notebooks, jobs, development flow	choosing a manual load pattern when an automated ingestion pattern fits
Data Processing & Transformations	21%	Spark SQL, DataFrame logic, Delta tables, transformations, quality checks	missing whether the operation appends, overwrites, merges, or transforms
Productionizing Data Pipelines	17%	jobs, tasks, orchestration, dependencies, retries, monitoring, scheduling	solving a production problem with an ad hoc notebook-only workflow
Data Governance & Quality	35%	Unity Catalog, permissions, lineage, sharing, constraints, quality controls	optimizing performance before setting the governance boundary

Must-know distinctions

Catalog versus schema versus table: answer many governance questions by locating the object boundary first.
Notebook run versus job task: notebooks are authoring units; jobs make work scheduled, observable, and repeatable.
Batch ingestion versus streaming ingestion: match freshness and operational needs before choosing tooling.
Delta table behavior versus raw file access: Delta adds transaction and management behavior that raw files do not.
Unity Catalog permissions versus workspace permissions: data access and workspace access are not the same control.
Cluster versus SQL warehouse: choose compute based on workload, user pattern, and operational boundary.
Development convenience versus production reliability: the production answer should be repeatable and monitored.

Common traps

Picking the most familiar Spark answer when the question asks for a Databricks-managed feature.
Ignoring Unity Catalog when the scenario mentions cross-team access, lineage, or data governance.
Replacing an existing table when the requirement says to append or preserve history.
Treating every freshness requirement as streaming.
Choosing a manual notebook workflow for an operational pipeline requirement.

Practice strategy

Use the free diagnostic as one baseline run, then tag misses by platform, ingestion, transformation, pipeline operations, or governance. If governance misses dominate, drill Unity Catalog and sharing before more mixed sets. If transformation misses dominate, slow down and identify the table operation before reading answer choices.
