Databricks Certified Data Engineer Professional Sample Questions:

Question 1

A developer has successfully configured their credentials for Databricks Repos and cloned a remote Git repository. They do not have privileges to make changes to the main branch, which is the only branch currently visible in their workspace. Which approach allows this user to share their code updates without the risk of overwriting the work of their teammates?

A. Use Repos to create a new branch commit all changes and push changes to the remote Git repertory.
B. Use Repos to merge all differences and make a pull request back to the remote repository.
C. Use repos to create a fork of the remote repository commit all changes and make a pull request on the source repository
D. Use repos to merge all difference and make a pull request back to the remote repository.
E. Use Repos to pull changes from the remote Git repository; commit and push changes to a branch that appeared as changes were pulled.

Question 2

A member of the data engineering team has submitted a short notebook that they wish to schedule as part of a larger data pipeline. Assume that the commands provided below produce the logically correct results when run as presented.

Which command should be removed from the notebook before scheduling it as a job?

A. Cmd 2
B. Cmd 5
C. Cmd 3
D. Cmd 4
E. Cmd 6

Question 3

A user new to Databricks is trying to troubleshoot long execution times for some pipeline logic they are working on. Presently, the user is executing code cell-by-cell, using display() calls to confirm code is producing the logically correct results as new transformations are added to an operation. To get a measure of average time to execute, the user is running each cell multiple times interactively.
Which of the following adjustments will get a more accurate measure of how code is likely to perform in production?

A. Scala is the only language that can be accurately tested using interactive notebooks; because the best performance is achieved by using Scala code compiled to JARs. all PySpark and Spark SQL logic should be refactored.
B. Production code development should only be done using an IDE; executing code against a local build of open source Spark and Delta Lake will provide the most accurate benchmarks for how code will perform in production.
C. The Jobs Ul should be leveraged to occasionally run the notebook as a job and track execution time during incremental code development because Photon can only be enabled on clusters launched for scheduled jobs.
D. The only way to meaningfully troubleshoot code execution times in development notebooks Is to use production-sized data and production-sized clusters with Run All execution.
E. Calling display () forces a job to trigger, while many transformations will only add to the logical query plan; because of caching, repeated execution of the same logic does not provide meaningful results.

Question 4

What is the first line of a Databricks Python notebook when viewed in a text editor?

A. // Databricks notebook source
B. # MAGIC %python
C. # Databricks notebook source
D. -- Databricks notebook source
E. %python

Question 5

A streaming video analytics team ingests billions of events daily into a Unity Catalog-managed Delta table video_events. Analysts run ad-hoc point-lookup queries on columns like user_id, campaign_id, and region. The team manually runs OPTIMIZE video_events ZORDER BY (user_id, campaign_id, region), but still sees poor performance on recent data and dislikes the operational overhead. The team wants a hands-off way to keep hot columns co-located as query patterns evolve. Which Delta capability should the team leverage on video_events?

A. Utilize Liquid Clustering (CLUSTER BY AUTO) and Predictive Optimization.
B. Schedule OPTIMIZE/ZORDER to run after each job to improve recent file performance.
C. Enable Delta caching.
D. Enable auto-compaction (optimizeWrite and autoCompact).
