Databricks Certified Professional Data Engineer Exam Sample Questions (Q12-Q17):

NEW QUESTION # 12
A table named user_ltv is being used to create a view that will be used by data analysis on various teams. Users in the workspace are configured into groups, which are used for setting up data access using ACLs.
The user_ltv table has the following schema:

An analyze who is not a member of the auditing group executing the following query:

Which result will be returned by this query?

A. All columns will be displayed normally for those records that have an age greater than 18; records not meeting this condition will be omitted.
B. All age values less than 18 will be returned as null values all other columns will be returned with the values in user_ltv.
C. All columns will be displayed normally for those records that have an age greater than 17; records not meeting this condition will be omitted.
D. All records from all columns will be displayed with the values in user_ltv.

Answer: A

Explanation:
Given the CASE statement in the view definition, the result set for a user not in the auditing group would be constrained by the ELSE condition, which filters out records based on age. Therefore, the view will return all columns normally for records with an age greater than 18, as users who are not in the auditing group will not satisfy the is_member('auditing') condition. Records not meeting the age > 18 condition will not be displayed.

NEW QUESTION # 13
Which of the following data workloads will utilize a Silver table as its source?

A. A job that cleans data by removing malformatted records
B. A job that queries aggregated data that already feeds into a dashboard
C. A job that aggregates cleaned data to create standard summary statistics
D. A job that ingests raw data from a streaming source into the Lakehouse
E. A job that enriches data by parsing its timestamps into a human-readable format

Answer: C

NEW QUESTION # 14
An analytics team wants to run a short-term experiment in Databricks SQL on the customer transactions Delta table (about 20 billion records) created by the data engineering team. Which strategy should the data engineering team use to ensure minimal downtime and no impact on the ongoing ETL processes?

A. Give the analytics team direct access to the production table.
B. Deep clone the table for the analytics team.
C. Create a new table for the analytics team using a CTAS statement.
D. Shallow clone the table for the analytics team.

Answer: D

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Exact extract: "A shallow clone creates a copy of the metadata that references the source data files; it is fast and inexpensive." Exact extract: "A deep clone copies the data." Exact extract: "Clones provide a point-in-time snapshot for experimentation without impacting the source." A shallow clone of the production Delta table creates an instantaneous snapshot that references the same data files, so it introduces virtually no downtime or storage overhead and avoids interfering with the ongoing ETL. A deep clone would copy all data (very expensive and slow for 20B rows). CTAS rewrites data and is unnecessary; direct access to prod risks contention and accidental changes.

NEW QUESTION # 15

A. INSERT IF EXISTS table_name

E. COPY INTO table_name
