Databricks DE-ASSOC Permissions and Lineage Guide

This lesson covers the operational governance evidence Databricks expects you to understand. DE-ASSOC is not testing permissions as random commands. It is testing whether you can reason about who should get access, where audit evidence lives, and how lineage helps explain upstream and downstream dependencies.

Audit log: Recorded evidence of actions or access events that helps explain who did what and when.

Lineage: Visibility into how data objects depend on or feed one another across a workflow.

Use-case map

Strong governance instincts

• grant access to clear groups or roles instead of improvising one-off access paths
• think in terms of governed objects and privileges, not only notebook code
• use audit evidence to explain access and operational history
• use lineage to explain data dependencies and downstream impact

High-yield chooser

Common traps

Candidates sometimes treat lineage as performance tooling or permissions as if they apply at only one level. DE-ASSOC wants cleaner thinking:

• permissions control governed access
• audit logs help prove activity
• lineage helps explain dependency and downstream effect

They are related, but they are not interchangeable.

Harder scenario question

A data engineer wants to understand which downstream assets could break before changing a shared upstream table. Which governance feature should they reach for first?

• A. More cluster memory
• B. Lineage
• C. A SQL warehouse
• D. Delta Sharing

Correct answer: B. The question is about dependency impact, which is exactly what lineage exists to show.

Decision order that usually wins

1. Decide whether the question is about access control, auditability, or dependency impact.
2. Fix the narrowest permission boundary that explains the symptom.
3. Use least-privilege reasoning before broad grants.
4. Read lineage as an operational clue about upstream and downstream effect.
5. Keep governance questions separate from transform-logic questions.
