DATABRICKS CERTIFIED DATA ENGINEER ASSOCIATE PRACTICE
EXAM ACTUAL EXAM 2026/2027 | COMPLETE EXAM-STYLE
QUESTIONS | 100% VERIFIED – DETAILED RATIONALES – PASS
GUARANTEED – A+ GRADED
1. A data engineer is designing a modern analytics platform using
Databricks. The organization requires a system that combines the
scalability of data lakes with the reliability and performance of
traditional data warehouses. Which Databricks architecture best
satisfies this requirement?
A. Lakehouse Architecture
B. Traditional Relational Database Architecture
C. File Server Architecture
D. Standalone Hadoop Cluster Without Metadata Management
Correct Answer: A
Rationale: The Lakehouse architecture combines the flexibility and
scalability of data lakes with the reliability, governance, and
performance capabilities of data warehouses.
2. Which Databricks technology provides ACID transactions, schema
enforcement, and reliable data management on top of cloud object
storage?
,2|Page
A. Delta Lake
B. Apache Kafka
C. MLflow
D. Databricks SQL Warehouse
Correct Answer: A
Rationale: Delta Lake adds reliability features such as ACID
transactions, schema enforcement, time travel, and optimized data
management to data lake storage.
3. A data engineer wants to create a new Delta table from a SQL query
result. Which command should be used?
A. CREATE TABLE AS SELECT
B. CREATE FILE AS QUERY
C. BUILD DELTA FROM SELECT
D. INSERT DATABASE USING QUERY
Correct Answer: A
Rationale: CREATE TABLE AS SELECT (CTAS) creates a table based on
the results of a SQL query.

4. Which Apache Spark component is responsible for distributing and
executing data processing tasks across a cluster?
A. Spark Engine
B. Spark Notebook Interface
C. Delta Catalog
D. DBFS Storage Layer
Correct Answer: A
Rationale: The Spark engine manages distributed computation by
dividing workloads into tasks executed across cluster resources.
5. A Databricks data engineer needs to automatically process newly
arriving files from cloud storage as they appear. Which feature is
designed for incremental file ingestion?
A. Auto Loader
B. Delta Sharing
C. MLflow Tracking
D. Databricks Repos
Correct Answer: A
, 4|Page
Rationale: Auto Loader incrementally discovers and processes new
files from cloud storage while efficiently handling large-scale
ingestion.
6. Which Databricks feature allows users to maintain multiple versions
of Delta Lake tables and query previous versions of the data?
A. Delta Lake Time Travel
B. Cluster Policies
C. Workspace Files
D. Job Scheduling
Correct Answer: A
Rationale: Delta Lake Time Travel allows users to access historical
versions of tables for auditing, recovery, and analysis.
7. A data engineer creates a Databricks job that executes a series of
notebooks every night. Which Databricks feature should be used to
automate this process?
A. Workflows (Jobs)
B. Unity Catalog
C. Delta Sharing
D. Secret Scopes
