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

問題 #1
A data engineer has built a customer order ingestion pipeline. The pipeline applies an expectation with ON VIOLATION DROP ROW to filter records where order_amount <= 0, and a separate quarantine table is defined to capture those dropped rows using a second expectation with ON VIOLATION DROP ROW on the inverse condition. The pipeline runs successfully, and the event log records constraint violations.
A stakeholder then requests that any pipeline run containing even a single negative order_amount record must halt immediately and require manual review before reprocessing, rather than silently dropping and quarantining those records.
The engineer changes the expectation mode from ON VIOLATION DROP ROW to ON VIOLATION FAIL UPDATE for the order_amount constraint and reruns the pipeline with a batch containing three invalid records.
What is the resulting behavior of the pipeline?

A. The pipeline emits a warning for each invalid record in the event log, continues processing all records, including the invalid ones, and completes the run without failure.
B. The pipeline halts immediately upon encountering the first invalid record, marks the update as failed, and requires manual intervention before the pipeline can be restarted.
C. The pipeline processes all valid records, drops the three invalid records into the quarantine table, and logs the violations in the event log without halting.
D. The pipeline moves all three invalid records to the quarantine table, then fails the update after completing ingestion of valid records, allowing partial results to be committed.

問題 #2
A data engineer is configuring a Databricks Asset Bundle to deploy a job with granular permissions. The requirements are:
* Grant the data-engineers group CAN_MANAGE access to the job.
* Ensure the auditors' group can view the job but not modify/run it.
* Avoid granting unintended permissions to other users/groups.
How should the data engineer deploy the job while meeting the requirements?

A. resources:jobs:my-job:name: data-pipelinetasks: [...]job: [...]permissions:- group_name: data-engineerslevel: CAN_MANAGEpermissions:- group_name: auditorslevel: CAN_VIEW

問題 #3
A data engineer at a financial services firm must enable two separate data collaboration initiatives. In the first initiative, the firm wants to combine its proprietary customer transaction records with a partner bank's credit risk scores to produce aggregate fraud-detection insights; neither party may expose raw customer records to the other due to regulatory constraints.
In the second initiative, the firm needs to share a curated, read-only Delta table of anonymized market trend data with an external analytics vendor whose team uses Python-based tools outside of Databricks.
Which two approaches satisfy the requirements?
Choose two.

A. Use a Databricks Clean Room for the market trend initiative, so that the external vendor can query the anonymized table without needing a Databricks account.
B. Use Databricks-to-Databricks OpenSharing for the fraud-detection initiative and apply a table-level row filter and column mask to the transaction table, so that the partner bank can join the data without seeing raw customer records.
C. Use Databricks-to-Open OpenSharing for the market trend initiative, so that the external vendor gets live, read-only access through an open-protocol Python client without needing a Databricks workspace.
D. Use Databricks-to-Databricks OpenSharing for the fraud-detection initiative, granting the partner bank read access to the transaction table under Unity Catalog governance.
E. Use a Databricks Clean Room for the fraud-detection initiative, allowing both parties to run joint analytical queries on the combined dataset without either party accessing the other's raw records.

問題 #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, these records will be overwritten.
D. Each write to the orders table will only contain unique records, but newly written records may have duplicates already present in the target table.
E. 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.

問題 #5
The marketing team is looking to share data in an aggregate table with the sales organization, but the field names used by the teams do not match, and a number of marketing specific fields have not been approval for the sales org.
Which of the following solutions addresses the situation while emphasizing simplicity?

A. Use a CTAS statement to create a derivative table from the marketing table configure a production jon to propagation changes.
B. Create a new table with the required schema and use Delta Lake's DEEP CLONE functionality to sync up changes committed to one table to the corresponding table.
C. Add a parallel table write to the current production pipeline, updating a new sales table that varies as required from marketing table.
D. Create a view on the marketing table selecting only these fields approved for the sales team alias the names of any fields that should be standardized to the sales naming conventions.
