최신 Databricks Certification Certified-Data-Engineer-Professional 무료샘플문제

문제 #1
A data engineer is setting up a pipeline to ingest data from a message bus system that occasionally delivers duplicate messages. The duplicate messages can be a week apart. The target is a Databricks Delta Lake table where each record should appear exactly once. Which Databricks ingestion pattern should be implemented to handle potential duplicates where events can arrive outside of the configured watermark?

A. Use Delta Lake time travel to identify and remove duplicates
B. Implement a write operation using MERGE INTO with a unique key
C. Configure Structured Streaming with dropDuplicates transformation
D. Use Delta Lake's change data feed to filter duplicate records

문제 #2
A data architect has designed a system in which two Structured Streaming jobs will concurrently write to a single bronze Delta table. Each job is subscribing to a different topic from an Apache Kafka source, but they will write data with the same schema. To keep the directory structure simple, a data engineer has decided to nest a checkpoint directory to be shared by both streams.
The proposed directory structure is displayed below:

Which statement describes whether this checkpoint directory structure is valid for the given scenario and why?

A. Yes; both of the streams can share a single checkpoint directory.
B. Yes; Delta Lake supports infinite concurrent writers.
C. No; each of the streams needs to have its own checkpoint directory.
D. No; Delta Lake manages streaming checkpoints in the transaction log.
E. No; only one stream can write to a Delta Lake table.

문제 #3
A junior member of the data engineering team is exploring the language interoperability of Databricks notebooks. The intended outcome of the below code is to register a view of all sales that occurred in countries on the continent of Africa that appear in the geo_lookup table.
Before executing the code, running SHOW TABLES on the current database indicates the database contains only two tables: geo_lookup and sales.

Which statement correctly describes the outcome of executing these command cells in order in an interactive notebook?

A. Both commands will fail. No new variables, tables, or views will be created.
B. Cmd 1 will succeed and Cmd 2 will fail, countries at will be a Python variable representing a PySpark DataFrame.
C. Cmd 1 will succeed and Cmd 2 will fail, countries at will be a Python variable containing a list of strings.
D. Cmd 1 will succeed. Cmd 2 will search all accessible databases for a table or view named countries af: if this entity exists, Cmd 2 will succeed.
E. Both commands will succeed. Executing show tables will show that countries at and sales at have been registered as views.

문제 #4
A distributed team of data analysts share computing resources on an interactive cluster with autoscaling configured. In order to better manage costs and query throughput, the workspace administrator is hoping to evaluate whether cluster upscaling is caused by many concurrent users or resource-intensive queries.
In which location can one review the timeline for cluster resizing events?

A. Driver's log file
B. Cluster Event Log
C. Workspace audit logs
D. Executor's log file
E. Ganglia

문제 #5
A data engineer is using Lakeflow Declarative Pipeline to propagate row deletions from a source bronze table (user_bronze) to a target silver table (user_silver). The engineer wants deletions in user_bronze to automatically delete corresponding rows in user_silver during pipeline execution.
Which configuration ensures deletions in the bronze table are propagated to the silver table?

A. Configure VACUUM on user_bronze to delete files, then rebuild user_silver from scratch.
B. Enable CDF on user_silver, read its transaction log, and use MERGE to sync deletions.
C. Enable Change Data Feed (CDF) on user_bronze, read its CDF stream, and use apply_changes() with apply_as_deletes=True for user_silver.
D. Use apply_changes without CDF and filter rows where _soft_deleted is true.
