Databricks Certified Data Engineer Professional 認定 Databricks-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) Workspace Admin privileges, cluster creation allowed. "Can Attach To" privileges on the required cluster
B) Cluster creation allowed. "Can Attach To" privileges on the required cluster
C) "Can Restart" privileges on the required cluster
D) Cluster creation allowed. "Can Restart" privileges on the required cluster
E) "Can Manage" privileges on the required cluster

2. Assuming that the Databricks CLI has been installed and configured correctly, which Databricks CLI command can be used to upload a custom Python Wheel to object storage mounted with the DBFS for use with a production job?

A) libraries
B) jobs
C) fs
D) workspace
E) configure

3. The data engineering team has configured a job to process customer requests to be forgotten (have their data deleted). All user data that needs to be deleted is stored in Delta Lake tables using default table settings.
The team has decided to process all deletions from the previous week as a batch job at 1am each Sunday. The total duration of this job is less than one hour. Every Monday at 3am, a batch job executes a series of VACUUM commands on all Delta Lake tables throughout the organization.
The compliance officer has recently learned about Delta Lake's time travel functionality. They are concerned that this might allow continued access to deleted data.
Assuming all delete logic is correctly implemented, which statement correctly addresses this concern?

A) Because the vacuum command permanently deletes all files containing deleted records, deleted records may be accessible with time travel for around 24 hours.
B) Because Delta Lake's delete statements have ACID guarantees, deleted records will be permanently purged from all storage systems as soon as a delete job completes.
C) Because the default data retention threshold is 7 days, data files containing deleted records will be retained until the vacuum job is run 8 days later.Get Latest & Actual Certified-Data-Engineer-Professional Exam's Question and Answers from
D) Because Delta Lake time travel provides full access to the entire history of a table, deleted records can always be recreated by users with full admin privileges.
E) Because the default data retention threshold is 24 hours, data files containing deleted records will be retained until the vacuum job is run the following day.

4. An upstream source writes Parquet data as hourly batches to directories named with the current date. A nightly batch job runs the following code to ingest all data from the previous day as indicated by the date variable:

Assume that the fields customer_id and order_id serve as a composite key to uniquely identify each order.
If the upstream system is known to occasionally produce duplicate entries for a single order hours apart, which statement is correct?

A) Each write to the orders table will run deduplication over the union of new and existing records, ensuring no duplicate records are present.
B) Each write to the orders table will only contain unique records, and only those records without duplicates in the target table will be written.
C) Each write to the orders table will only contain unique records; if existing records with the same key are present in the target table, the operation will tail.
D) Each write to the orders table will only contain unique records; if existing records with the same key are present in the target table, these records will be overwritten.
E) Each write to the orders table will only contain unique records, but newly written records may have duplicates already present in the target table.

5. A Delta table of weather records is partitioned by date and has the below schema:
date DATE, device_id INT, temp FLOAT, latitude FLOAT, longitude FLOAT
To find all the records from within the Arctic Circle, you execute a query with the below filter:
latitude > 66.3
Which statement describes how the Delta engine identifies which files to load?

A) All records are cached to attached storage and then the filter is applied Get Latest & Actual Certified-Data-Engineer-Professional Exam's Question and Answers from
B) The Delta log is scanned for min and max statistics for the latitude column
C) All records are cached to an operational database and then the filter is applied
D) The Hive metastore is scanned for min and max statistics for the latitude column
E) The Parquet file footers are scanned for min and max statistics for the latitude column
