Google Data Engineer 認定 GCP-DE 試験問題 (Q53-Q58):

質問 # 53
You receive data files in CSV format monthly from a third party. You need to cleanse this data, but every third month the schema of the files changes. Your requirements for implementing these transformations include:
Executing the transformations on a schedule
Enabling non-developer analysts to modify transformations
Providing a graphical tool for designing transformations
What should you do?

A. Merge the transformed tables together with a SQL query
B. The Python code should be stored in a revision control system and modified as the incoming data's schema changes
C. Load each month's CSV data into BigQuery, and write a SQL query to transform the data to a standard scheme
D. Help the analysts write a Cloud Dataflow pipeline in Python to perform the transformatio
E. Use Cloud Dataprep to build and maintain the transformation recipes, and execute them on a scheduled basis
F. Use Apache Spark on Cloud Dataproc to infer the schema of the CSV file before creating a Dataframe.Then implement the transformations in Spark SQL before writing the data out to Cloud Storage and loading into BigQuery

正解：D

質問 # 54
When using Cloud Dataproc clusters, you can access the YARN web interface by configuring a browser to connect through a proxy.

A. SOCKS
B. HTTP
C. VPN
D. HTTPS

正解：A

解説：
When using Cloud Dataproc clusters, configure your browser to use the SOCKS proxy. The SOCKS proxy routes data intended for the Cloud Dataproc cluster through an SSH tunnel.
Reference: https://cloud.google.com/dataproc/docs/concepts/cluster-web-interfaces#interfaces

質問 # 55
Which Cloud Dataflow / Beam feature should you use to aggregate data in an unbounded data source every hour based on the time when the data entered the pipeline?

A. A processing time trigger
B. The with Allowed Lateness method
C. An hourly watermark
D. An event time trigger

正解：A

解説：
When collecting and grouping data into windows, Beam uses triggers to determine when to emit the aggregated results of each window.
Processing time triggers. These triggers operate on the processing time - the time when the data element is processed at any given stage in the pipeline. Event time triggers. These triggers operate on the event time, as indicated by the timestamp on each data element. Beam's default trigger is event time-based.

質問 # 56
You used Cloud Dataprep to create a recipe on a sample of data in a BigQuery table. You want to reuse this recipe on a daily upload of data with the same schema, after the load job with variable execution time completes. What should you do?

A. Export the recipe as a Cloud Dataprep template, and create a job in Cloud Scheduler.
B. Create a cron schedule in Cloud Dataprep.
C. Create an App Engine cron job to schedule the execution of the Cloud Dataprep job.
D. Export the Cloud Dataprep job as a Cloud Dataflow template, and incorporate it into a Cloud Composer job.

正解：A

質問 # 57
You need to deploy additional dependencies to all of a Cloud Dataproc cluster at startup using an existing initialization action. Company security policies require that Cloud Dataproc nodes do not have access to the Internet so public initialization actions cannot fetch resources. What should you do?

A. Copy all dependencies to a Cloud Storage bucket within your VPC security perimeter
B. Use Resource Manager to add the service account used by the Cloud Dataproc cluster to the Network User role
C. Use an SSH tunnel to give the Cloud Dataproc cluster access to the Internet
D. Deploy the Cloud SQL Proxy on the Cloud Dataproc master

正解：B
