Databricks Certified Data Engineer Professional 認定 Certified-Data-Engineer-Professional 試験問題：

1. The Databricks workspace administrator has configured interactive clusters for each of the data engineering groups. To control costs, clusters are set to terminate after 30 minutes of inactivity.
Each user should be able to execute workloads against their assigned clusters at any time of the day.
Assuming users have been added to a workspace but not granted any permissions, which of the following describes the minimal permissions a user would need to start and attach to an already configured cluster.

A) Cluster creation allowed. "Can Attach To" privileges on the required cluster
B) Cluster creation allowed. "Can Restart" privileges on the required cluster
C) "Can Manage" privileges on the required cluster
D) Workspace Admin privileges, cluster creation allowed. "Can Attach To" privileges on the required cluster
E) "Can Restart" privileges on the required cluster

2. A data engineer is creating a data ingestion pipeline to understand where customers are taking their rented bicycles during use. The engineer noticed that, over time, data being transmitted from the bicycle sensors fail to include key details like latitude and longitude. Downstream analysts need both the clean records and the quarantined records available for separate processing.
The data engineer already has this code:
import dlt
from pyspark.sql.functions import expr
rules = {
"valid_lat": "(lat IS NOT NULL)",
"valid_long": "(long IS NOT NULL)"
}
quarantine_rules = "NOT({})".format(" AND ".join(rules.values()))
@dlt.view
def raw_trips_data():
return spark.readStream.table("ride_and_go.telemetry.trips")
How should the data engineer meet the requirements to capture good and bad data?

A) @dlt.table(name="trips_data_quarantine")
def trips_data_quarantine():
return (
spark.readStream.table("raw_trips_data")
.filter(expr(quarantine_rules))
)
B) @dlt.view
@dlt.expect_or_drop("lat_long_present", "(lat IS NOT NULL AND long IS NOT NULL)") def trips_data_quarantine():
return spark.readStream.table("ride_and_go.telemetry.trips")
C) @dlt.table
@dlt.expect_all_or_drop(rules)
def trips_data_quarantine():
return spark.readStream.table("raw_trips_data")
D) @dlt.table(partition_cols=["is_quarantined", ])
@dlt.expect_all(rules)
def trips_data_quarantine():
return (
spark.readStream.table("raw_trips_data")
.withColumn("is_quarantined", expr(quarantine_rules))
)

3. Which Python variable contains a list of directories to be searched when trying to locate required modules?

A) os.path
B) importlib.resource path
C) pylib.source
D) sys.path
E) pypi.path

4. A data engineer has a Delta table orders with deletion vectors enabled. The engineer executes the following command:
DELETE FROM orders WHERE status = 'cancelled';
What should be the behavior of deletion vectors when the command is executed?

A) Delta automatically removes all cancelled orders permanently.
B) Rows are marked as deleted in metadata, not in files.
C) Files are physically rewritten without the deleted rows.
D) Rows are marked as deleted both in metadata and in files.

5. The security team is exploring whether or not the Databricks secrets module can be leveraged for connecting to an external database.
After testing the code with all Python variables being defined with strings, they upload the password to the secrets module and configure the correct permissions for the currently active user. They then modify their code to the following (leaving all other variables unchanged).

Which statement describes what will happen when the above code is executed?

A) An interactive input box will appear in the notebook; if the right password is provided, the connection will succeed and the password will be printed in plain text.
B) The connection to the external table will fail; the string "redacted" will be printed.
C) An interactive input box will appear in the notebook; if the right password is provided, the connection will succeed and the encoded password will be saved to DBFS.
D) The connection to the external table will succeed; the string value of password will be printed in plain text.
E) The connection to the external table will succeed; the string "redacted" will be printed.
