Databricks Certified Data Engineer Professional Sample Questions:

1. To identify the top users consuming compute resources, a data engineering team needs to monitor usage within their Databricks workspace for better resource utilization and cost control.
The team decided to use Databricks system tables, available under the System catalog in Unity Catalog, to gain detailed visibility into workspace activity. Which SQL query should the team run from the System catalog to achieve this?

A) SELECT sku_name,
identity_metadata.created_by AS user_email,
SUM(usage_quantity * usage_unit) AS total_dbus
FROM system.billing.usage
GROUP BY user_email, sku_name
ORDER BY total_dbus DESC
LIMIT 10
B) SELECT sku_name,
usage_metadata.run_name AS user_email,
SUM(usage_quantity) AS total_dbus
FROM system.billing.usage
GROUP BY user_email, sku_name
ORDER BY total_dbus DESC
LIMIT 10
C) SELECT sku_name,
identity_metadata.created_by AS user_email,
COUNT(usage_quantity) AS total_dbus
FROM system.billing.usage
GROUP BY user_email, sku_name
ORDER BY total_dbus DESC
LIMIT 10
D) SELECT identity_metadata.run_as AS user_email,
SUM(usage_quantity) AS total_dbus
FROM system.billing.usage
GROUP BY user_email
ORDER BY total_dbus DESC
LIMIT 10

2. A job runs four independent tasks (X, Y, Z, W) in parallel to process regional sales data. The Data Engineering team recently updated its cluster policy to ban cost-prohibitive instance types. Task Y now fails due to the newly enforced cluster policy restricting the use of a specific instance type.
A data engineer needs to resolve the failure quickly without disrupting the other tasks. How should the data engineer resolve the failure of tasks?

A) Use "Repair run", override the cluster configuration for Task Y to use a permitted instance type, and let Databricks re-run only Task Y.
B) Edit the global cluster policy to allow the restricted instance type, then re-run the entire job.
C) Manually create a new cluster for Task Y, update the job configuration, and trigger a full re-run.
D) Delete the failed run, disable the cluster policy, and re-execute all tasks.

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

4. A data engineer is configuring Delta Sharing for a Databricks-to-Databricks scenario to optimize read performance. The recipient needs to perform time travel queries and streaming reads on shared sales data. Which configuration will provide the optimal performance while enabling these capabilities?

A) Use the open sharing protocol instead of Databricks-to-Databricks sharing for better performance.
B) Share tables WITHOUT HISTORY and enable partitioning for better query performance.
C) Share tables WITH HISTORY, ensure tables don't have partitioning enabled, and enable CDF before sharing.
D) Share the entire schema WITHOUT HISTORY and rely on recipient-side caching for performance.

5. Which REST API call can be used to review the notebooks configured to run as tasks in a multi- task job?

A) /jobs/runs/list
B) /jobs/runs/get
C) /jobs/list
D) /jobs/get
E) /jobs/runs/get-output
