◉ A data architect is designing a data model that works for both
video-based machine learning workloads and highly audited batch
ETL/ELT workloads. Which of the following describes how using a
data lakehouse can help the data architect meet the needs of both
workloads?
A. A data lakehouse requires very little data modeling.

D. A data lakehouse stores unstructured data and is ACID-compliant.
,E. A data lakehouse fully exists in the cloud. Answer: D. A data
lakehouse stores unstructured data and is ACID-compliant.
◉ Which of the following describes a scenario in which a data
engineer will want to use a Job cluster instead of an all-purpose
cluster?
A. An ad-hoc analytics report needs to be developed while
minimizing compute costs.
B. A data team needs to collaborate on the development of a
machine learning model.
C. An automated workflow needs to be run every 30 minutes.
D. A Databricks SQL query needs to be scheduled for upward
reporting.
E. A data engineer needs to manually investigate a production error.
Answer: C. An automated workflow needs to be run every 30
minutes.
◉ A data engineer has created a Delta table as part of a data
pipeline. Downstream data analysts now need SELECT permission
on the Delta table. Assuming the data engineer is the Delta table
owner, which part of the Databricks Lakehouse Platform can the
data engineer use to grant the data analysts the appropriate access?

versioning B. Databricks Notebooks support real-time coauthoring
on a single notebook C. Databricks Notebooks support commenting
and notification comments
D. Databricks Notebooks support the use of multiple languages in
the same notebook
E. Databricks Notebooks support the creation of interactive data
visualizations Answer: B. Databricks Notebooks support real-time
coauthoring on a single notebook

facilitate CI/CD workflows on the Databricks Lakehouse Platform?
A. Databricks Repos can facilitate the pull request, review, and
approval process before merging branches
, B. Databricks Repos can merge changes from a secondary Git branch
into a main Git branch
C. Databricks Repos can be used to design, develop, and trigger Git
automation pipelines
D. Databricks Repos can store the single-source-of-truth Git
repository
E. Databricks Repos can commit or push code changes to trigger a
CI/CD process Answer: E. Databricks Repos can commit or push
code changes to trigger a CI/CD process
◉ Which of the following statements describes Delta Lake?
A. Delta Lake is an open source analytics engine used for big data
workloads. B. Delta Lake is an open format storage layer that
delivers reliability, security, and performance.
C. Delta Lake is an open source platform to help manage the
complete machine learning lifecycle.
D. Delta Lake is an open source data storage format for distributed
data.
E. Delta Lake is an open format storage layer that processes data.
Answer: B. Delta Lake is an open format storage layer that delivers
reliability, security, and performance.
