Databricks Certified Data Engineer Professional Certified-Data-Engineer-Professional Prüfungsfragen mit Lösungen

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 merge all difference and make a pull request back to the remote repository.
D) Use repos to create a fork of the remote repository commit all changes and make a pull request on the source 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.

2. The downstream consumers of a Delta Lake table have been complaining about data quality issues impacting performance in their applications. Specifically, they have complained that invalid latitude and longitude values in the activity_details table have been breaking their ability to use other geolocation processes.
A junior engineer has written the following code to add CHECK constraints to the Delta Lake table:

A senior engineer has confirmed the above logic is correct and the valid ranges for latitude and longitude are provided, but the code fails when executed.
Which statement explains the cause of this failure?

A) The activity details table already exists; CHECK constraints can only be added during initial table creation.
B) The activity details table already contains records that violate the constraints; all existing data must pass CHECK constraints in order to add them to an existing table.
C) Because another team uses this table to support a frequently running application, two-phase locking is preventing the operation from committing.
D) The current table schema does not contain the field valid coordinates; schema evolution will need to be enabled before altering the table to add a constraint.
E) The activity details table already contains records; CHECK constraints can only be added prior to inserting values into a table.

3. A data engineer needs to provide access to a group named manufacturing-team. The team needs privileges to create tables in the quality schema. Which set of SQL commands will grant a group named manufacturing-team to create tables in a schema named production with the parent catalog named manufacturing with the least privileges?

A) GRANT CREATE TABLE ON SCHEMA manufacturing.quality TO manufacturing-team; GRANT USE SCHEMA ON SCHEMA manufacturing.quality TO manufacturing-team; GRANT USE CATALOG ON CATALOG manufacturing TO manufacturing-team;
B) GRANT CREATE TABLE ON SCHEMA manufacturing.quality TO manufacturing-team; GRANT CREATE SCHEMA ON SCHEMA manufacturing.quality TO manufacturing-team; GRANT USE CATALOG ON CATALOG manufacturing TO manufacturing-team;
C) GRANT USE TABLE ON SCHEMA manufacturing.quality TO manufacturing-team; GRANT USE SCHEMA ON SCHEMA manufacturing.quality TO manufacturing-team; GRANT USE CATALOG ON CATALOG manufacturing TO manufacturing-team;
D) GRANT CREATE TABLE ON SCHEMA manufacturing.quality TO manufacturing-team; GRANT CREATE SCHEMA ON SCHEMA manufacturing.quality TO manufacturing-team; GRANT CREATE CATALOG ON CATALOG manufacturing TO manufacturing-team;

4. A data engineer wants to ingest a large collection of image files (JPEG and PNG) from cloud object storage into a Unity Catalog-managed table for analysis and visualization. Which two configurations and practices are recommended to incrementally ingest these images into the table? (Choose two.)

A) Move files to a volume and read with SQL editor.
B) Use Auto Loader and set cloudFiles.format to "BINARYFILE".
C) Use the pathGlobFilter option to select only image files (e.g., "*.jpg,*.png").
D) Use Auto Loader and set cloudFiles.format to "IMAGE".
E) Use Auto Loader and set cloudFiles.format to "TEXT".

5. The data science team has requested assistance in accelerating queries on free form text from user reviews. The data is currently stored in Parquet with the below schema:
item_id INT, user_id INT, review_id INT, rating FLOAT, review STRING
The review column contains the full text of the review left by the user. Specifically, the data science team is looking to identify if any of 30 key words exist in this field.
A junior data engineer suggests converting this data to Delta Lake will improve query performance.
Which response to the junior data engineer's suggestion is correct?

A) Delta Lake statistics are not optimized for free text fields with high cardinality.
B) The Delta log creates a term matrix for free text fields to support selective filtering.
C) ZORDER ON review will need to be run to see performance gains.
D) Text data cannot be stored with Delta Lake.
E) Delta Lake statistics are only collected on the first 4 columns in a table.
