A data engineer has three notebooks in an ELT pipeline. The notebooks need to
be executed in a specific order for the pipeline to complete successfully. The data
engineer would like to use Delta Live Tables to manage this process. Which of the
following steps must the data engineer take as part of implementing this pipeline
using Delta Live Tables?
A. They need to create a Delta Live Tables pipeline from the Data page.
B. They need to create a Delta Live Tables pipeline from the Jobs page.
C. They need to create a Delta Live tables pipeline from the Compute page.
D. They need to refactor their notebook to use Python and the dlt library.
E. They need to refactor their notebook to use SQL and CREATE LIVE TABLE
keyword. - ANSWERS-B. They need to create a Delta Live Tables pipeline from the
Jobs page.
,A data engineer has written the following query:
SELECT *
FROM json.`/path/to/json/file.json`;
The data engineer asks a colleague for help to convert this query for use in a Delta
Live Tables (DLT) pipeline. The query should create the first table in the DLT
pipeline. Which of the following describes the change the colleague needs to
make to the query?
A. They need to add a COMMENT line at the beginning of the query.
B. They need to add a CREATE LIVE TABLE table_name AS line at the beginning of
the query.
C. They need to add a live. prefix prior to json. in the FROM line.
D. They need to add a CREATE DELTA LIVE TABLE table_name AS line at the
beginning of the query.
E. They need to add the cloud_files(...) wrapper to the JSON file path. - ANSWERS-
B. They need to add a CREATE LIVE TABLE table_name AS line at the beginning of
the query.
A dataset has been defined using Delta Live Tables and includes an expectations
clause:
What is the expected behavior when a batch of data containing data that violates
these constraints is processed?
A. Records that violate the expectation are added to the target dataset and
recorded as invalid in the event log.
,B. Records that violate the expectation are dropped from the target dataset and
recorded as invalid in the event log.
C. Records that violate the expectation cause the job to fail.
D. Records that violate the expectation are added to the target dataset and
flagged as invalid in a field added to the target dataset.
E. Records that violate the expectation are dropped from the target dataset and
loaded into a quarantine table. - ANSWERS-A. Records that violate the
expectation are added to the target dataset and recorded as invalid in the event
log.
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.
B. A data lakehouse combines compute and storage for simple governance.
C. A data lakehouse provides autoscaling for compute clusters.
D. A data lakehouse stores unstructured data and is ACID-compliant.
E. A data lakehouse fully exists in the cloud. - ANSWERS-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. - ANSWERS-
C. An automated workflow needs to be run every 30 minutes.
Which of the following describes a benefit of a data lakehouse that is unavailable
in a traditional data warehouse?
A. A data lakehouse provides a relational system of data management.
B. A data lakehouse captures snapshots of data for version control purposes.
C. A data lakehouse couples storage and compute for complete control.
D. A data lakehouse utilizes proprietary storage formats for data.
E. A data lakehouse enables both batch and streaming analytics - ANSWERS-E. A
data lakehouse enables both batch and streaming analytics
Which of the following locations hosts the driver and worker nodes of a
Databricks-managed cluster?
A. Data plane
B. Control plane
C. Databricks Filesystem
D. JDBC data source
