A team is designing their Data bricks Asset Bundle for deployment. They want to ensure their bundle includes all necessary resources, targeted environment configurations, and deployment settings in a single version-controlled file. What is required as the main configuration file at the root of their project?

Which of the following benefits of using the Databricks Lakehouse Platform is provided by Delta Lake?

A data engineer is configuring a cluster in Databricks and wants to ensure that multiple Spark executors can run tasks concurrently across worker nodes. Which cluster component is responsible for executing tasks?

Which of the following describes the relationship between Bronze tables and raw data?

A data engineer needs to ingest from both streaming and batch sources for a firm that relies on highly accurate data. Occasionally, some of the data picked up by the sensors that provide a streaming input are outside the expected parameters. If this occurs, the data must be dropped, but the stream should not fail. Which feature of Delta Live Tables meets this requirement?

A developer is building a data pipeline that processes records from a bronze table into a silver table. The bronze table, bronze_events, contains duplicate records due to at-least-once delivery guarantees from the upstream ingestion system. The developer writes the following PySpark code to prepare the data:

The developer notices that after running dropDuplicates() without arguments, some rows that differ only in the event_timestamp column remain. The developer wants to de-duplicate based only on user_id and event_type, keeping one row per unique combination of these two columns.
Which code change achieves this deduplication requirement?

A data engineer wants a Structured Streaming job to process all data available in the source, then stop automatically, so it can run on a scheduled job cluster instead of running continuously.
Which trigger should be configured?

A data engineer wants to create a relational object by pulling data from two tables. The relational object does not need to be used by other data engineers in other sessions. In order to save on storage costs, the data engineer wants to avoid copying and storing physical data.
Which of the following relational objects should the data engineer create?

A data engineer needs to use a Delta table as part of a data pipeline, but they do not know if they have the appropriate permissions. In which location can the data engineer review their permissions on the table?

A data engineer has finished developing a new Declarative Automation Bundle (formerly Databricks Asset Bundle) for a streaming pipeline. They need to ensure the configuration is syntactically correct, push the code to the workspace, and finally trigger the pipeline to verify it runs as expected. Which sequence of Databricks CLI commands should the engineer use to perform these steps in the correct order?

Which of the following data lakehouse features results in improved data quality over a traditional data lake?

A data engineer is building an ETL pipeline in Databricks that loads raw JSON files from cloud object storage into a Delta Lake table. The pipeline must ensure ACID transactions and schema enforcement while supporting scalable reads and writes from multiple concurrent jobs. Which storage format should the engineer use?

Which of the following describes the relationship between Gold tables and Silver tables?

A Data Engineer is designing Bronze layer in Databricks Medallion Architecture. The raw data is collected from multiple sources (Clickstream in JSON, Transactions in CSV).
The task is to design the Bronze layer of the Medallion Architecture to ingest and store this raw data for further processing.
Which operation applies to the Bronze layer?
