최신 Databricks Certification Databricks-Certified-Data-Engineer-Professional 무료샘플문제:

1. A Databricks SQL dashboard has been configured to monitor the total number of records present in a collection of Delta Lake tables using the following query pattern:
SELECT COUNT (*) FROM table
Which of the following describes how results are generated each time the dashboard is updated?

A) The total count of records is calculated from the Hive metastore
B) The total count of rows is calculated by scanning all data files
C) The total count of records is calculated from the parquet file metadata
D) The total count of rows will be returned from cached results unless REFRESH is run
E) The total count of records is calculated from the Delta transaction logs

2. The data engineer team is configuring environment for development testing, and production before beginning migration on a new data pipeline. The team requires extensive testing on both the code and data resulting from code execution, and the team want to develop and test against similar production data as possible.
A junior data engineer suggests that production data can be mounted to the development testing environments, allowing pre production code to execute against production data. Because all users have Admin privileges in the development environment, the junior data engineer has offered to configure permissions and mount this data for the team.
Which statement captures best practices for this situation?

A) Because access to production data will always be verified using passthrough credentials it is safe to mount data to any Databricks development environment.
B) Because delta Lake versions all data and supports time travel, it is not possible for user error or malicious actors to permanently delete production data, as such it is generally safe to mount production data anywhere.
C) All developer, testing and production code and data should exist in a single unified workspace; creating separate environments for testing and development further reduces risks.
D) In environments where interactive code will be executed, production data should only be accessible with read permissions; creating isolated databases for each environment further reduces risks.

3. A Spark job is taking longer than expected. Using the Spark UI, a data engineer notes that the Min, Median, and Max Durations for tasks in a particular stage show the minimum and median time to complete a task as roughly the same, but the max duration for a task to be roughly 100 times as long as the minimum.
Which situation is causing increased duration of the overall job?

A) Skew caused by more data being assigned to a subset of spark-partitions.
B) Task queueing resulting from improper thread pool assignment.
C) Network latency due to some cluster nodes being in different regions from the source data
D) Credential validation errors while pulling data from an external system.
E) Spill resulting from attached volume storage being too small.

4. A developer has successfully configured credential for Databricks Repos and cloned a remote Git repository. Hey don not have privileges to make changes to the main branch, which is the only branch currently visible in their workspace.
Use Response to pull changes from the remote Git repository commit and push changes to a branch that appeared as a changes were pulled.

A) Use repos to create a fork of the remote repository commit all changes and make a pull request on the source repository
B) Use repos to merge all difference and make a pull request back to the remote repository.
C) Use Repos to create a new branch commit all changes and push changes to the remote Git repertory.

Assuming that this code produces logically correct results and the data in the source table has been de-duplicated and validated, which statement describes what will occur when this code is executed?

A) The gold_customer_lifetime_sales_summary table will be overwritten by aggregated values calculated from all records in the silver_customer_sales table as a batch job.
B) The silver_customer_sales table will be overwritten by aggregated values calculated from all records in the gold_customer_lifetime_sales_summary table as a batch job.
C) A batch job will update the gold_customer_lifetime_sales_summary table, replacing only those rows that have different values than the current version of the table, using customer_id as the primary key.
D) An incremental job will detect if new rows have been written to the silver_customer_sales table; if new rows are detected, all aggregates will be recalculated and used to overwrite the gold_customer_lifetime_sales_summary table.
E) An incremental job will leverage running information in the state store to update aggregate values in the gold_customer_lifetime_sales_summary table.
