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

1. The data engineering team has configured a Databricks SQL query and alert to monitor the values in a Delta Lake table. The recent_sensor_recordings table contains an identifying sensor_id alongside the timestamp and temperature for the most recent 5 minutes of recordings.
The below query is used to create the alert:

The query is set to refresh each minute and always completes in less than 10 seconds. The alert is set to trigger when mean (temperature) > 120. Notifications are triggered to be sent at most every 1 minute.
If this alert raises notifications for 3 consecutive minutes and then stops, which statement must be true?

A) The average temperature recordings for at least one sensor exceeded 120 on three consecutive executions of the query
B) The recent_sensor_recordingstable was unresponsive for three consecutive runs of the query
C) The total average temperature across all sensors exceeded 120 on three consecutive executions of the query
D) The maximum temperature recording for at least one sensor exceeded 120 on three consecutive executions of the query
E) The source query failed to update properly for three consecutive minutes and then restarted

2. The data engineer team has been tasked with configured connections to an external database that does not have a supported native connector with Databricks. The external database already has data security configured by group membership. These groups map directly to user group already created in Databricks that represent various teams within the company.
A new login credential has been created for each group in the external database. The Databricks Utilities Secrets module will be used to make these credentials available to Databricks users.
Assuming that all the credentials are configured correctly on the external database and group membership is properly configured on Databricks, which statement describes how teams can be granted the minimum necessary access to using these credentials?

A) ''Read'' permissions should be set on a secret key mapped to those credentials that will be used by a given team.
B) "Read" permissions should be set on a secret scope containing only those credentials that will be used by a given team.
C) No additional configuration is necessary as long as all users are configured as administrators in the workspace where secrets have been added.
D) "Manage" permission should be set on a secret scope containing only those credentials that will be used by a given team.

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. Cmd 2 will search all accessible databases for a table or view named countries af: if this entity exists, Cmd 2 will succeed.
C) Both commands will succeed. Executing show tables will show that countries at and sales at have been registered as views.
D) Cmd 1 will succeed and Cmd 2 will fail, countries at will be a Python variable containing a list of strings.
E) Cmd 1 will succeed and Cmd 2 will fail, countries at will be a Python variable representing a PySpark DataFrame.

4. A nightly job ingests data into a Delta Lake table using the following code:

The next step in the pipeline requires a function that returns an object that can be used to manipulate new records that have not yet been processed to the next table in the pipeline.
Which code snippet completes this function definition?
def new_records():

A) return spark.readStream.table("bronze")
B) return spark.read.option("readChangeFeed", "true").table ("bronze")
C) return spark.readStream.load("bronze")
D)

5. A production workload incrementally applies updates from an external Change Data Capture feed to a Delta Lake table as an always-on Structured Stream job. When data was initially migrated for this table, OPTIMIZE was executed and most data files were resized to 1 GB. Auto Optimize and Auto Compaction were both turned on for the streaming production job. Recent review of data files shows that most data files are under 64 MB, although each partition in the table contains at least 1 GB of data and the total table size is over 10 TB.
Which of the following likely explains these smaller file sizes?

A) Databricks has autotuned to a smaller target file size based on the overall size of data in the table
B) Databricks has autotuned to a smaller target file size to reduce duration of MERGE operations
C) Z-order indices calculated on the table are preventing file compaction C Bloom filler indices calculated on the table are preventing file compaction
D) Databricks has autotuned to a smaller target file size based on the amount of data in each partition
