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

1. A data engineering team has a time-consuming data ingestion job with three data sources. Each notebook takes about one hour to load new data. One day, the job fails because a notebook update introduced a new required configuration parameter. The team must quickly fix the issue and load the latest data from the failing source. Which action should the team take?

A) Share the analysis with the failing notebook owner so that they can fix it quickly.
B) Repair the run with the new parameter.
C) Repair the run with the new parameter, and update the task by adding the missing task parameter.
D) Update the task by adding the missing task parameter, and manually run the job.

2. A data architect has designed a system in which two Structured Streaming jobs will concurrently write to a single bronze Delta table. Each job is subscribing to a different topic from an Apache Kafka source, but they will write data with the same schema. To keep the directory structure simple, a data engineer has decided to nest a checkpoint directory to be shared by both streams.
The proposed directory structure is displayed below:

Which statement describes whether this checkpoint directory structure is valid for the given scenario and why?

A) Yes; both of the streams can share a single checkpoint directory.
B) No; Delta Lake manages streaming checkpoints in the transaction log.
C) No; only one stream can write to a Delta Lake table.
D) No; each of the streams needs to have its own checkpoint directory.
E) Yes; Delta Lake supports infinite concurrent writers.

3. The business reporting tem requires that data for their dashboards be updated every hour. The total processing time for the pipeline that extracts transforms and load the data for their pipeline runs in 10 minutes.
Assuming normal operating conditions, which configuration will meet their service-level agreement requirements with the lowest cost?

A) Schedule a Structured Streaming job with a trigger interval of 60 minutes.
B) Schedule a job to execute the pipeline once an hour on a new job cluster.
C) Schedule a job to execute the pipeline once an hour on a dedicated interactive cluster.
D) Configure a job that executes every time new data lands in a given directory.

4. A data engineer wants to refactor the following DLT code, which includes multiple table definitions with very similar code.

In an attempt to programmatically create these tables using a parameterized table definition, the data engineer writes the following code.

The pipeline runs an update with this refactored code, but generates a different DAG showing incorrect configuration values for these tables.
How can the data engineer fix this?

A) Convert the list of configuration values to a dictionary of table settings, using table names as keys.
B) Load the configuration values for these tables from a separate file, located at a path provided by a pipeline parameter.
C) Wrap the loop inside another table definition, using generalized names and properties to replace with those from the inner table
D) Convert the list of configuration values to a dictionary of table settings, using different input the for loop.

5. 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 default data retention threshold is 24 hours, data files containing deleted records will be retained until the vacuum job is run the following day.
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.
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 vacuum command permanently deletes all files containing deleted records, deleted records may be accessible with time travel for around 24 hours.
