Google Data Engineer 認定 GCP-DE 試験問題 (Q73-Q78):
質問 # 73
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. Load each month's CSV data into BigQuery, and write a SQL query to transform the data to a standard scheme
- C. Use Cloud Dataprep to build and maintain the transformation recipes, and execute them on a scheduled basis
- D. The Python code should be stored in a revision control system and modified as the incoming data's schema changes
- E. 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
- F. Help the analysts write a Cloud Dataflow pipeline in Python to perform the transformatio
正解:F
質問 # 74
You architect a system to analyze seismic dat
a. Your extract, transform, and load (ETL) process runs as a series of MapReduce jobs on an Apache Hadoop cluster. The ETL process takes days to process a data set because some steps are computationally expensive. Then you discover that a sensor calibration step has been omitted. How should you change your ETL process to carry out sensor calibration systematically in the future?
- A. Develop an algorithm through simulation to predict variance of data output from the last MapReduce job based on calibration factors, and apply the correction to all data.
- B. Add sensor calibration data to the output of the ETL process, and document that all users need to apply sensor calibration themselves.
- C. Modify the transformMapReduce jobs to apply sensor calibration before they do anything else.
- D. Introduce a new MapReduce job to apply sensor calibration to raw data, and ensure all other MapReduce jobs are chained after this.
正解:C
質問 # 75
You are operating a Cloud Dataflow streaming pipeline. The pipeline aggregates events from a Cloud Pub/Sub subscription source, within a window, and sinks the resulting aggregation to a Cloud Storage bucket. The source has consistent throughput. You want to monitor an alert on behavior of the pipeline with Cloud Stackdriver to ensure that it is processing dat a. Which Stackdriver alerts should you create?
- A. An alert based on a decrease of subscription/num_undelivered_messages for the source and a rate of change increase of instance/storage/used_bytes for the destination
- B. An alert based on a decrease of instance/storage/used_bytes for the source and a rate of change increase of subscription/num_undelivered_messages for the destination
- C. An alert based on an increase of instance/storage/used_bytes for the source and a rate of change decrease of subscription/num_undelivered_messages for the destination
- D. An alert based on an increase of subscription/num_undelivered_messages for the source and a rate of change decrease of instance/storage/used_bytes for the destination
正解:D
質問 # 76
You have developed three data processing jobs. One executes a Cloud Dataflow pipeline that transforms data uploaded to Cloud Storage and writes results to BigQuery. The second ingests data from on-premises servers and uploads it to Cloud Storage. The third is a Cloud Dataflow pipeline that gets information from third-party data providers and uploads the information to Cloud Storage. You need to be able to schedule and monitor the execution of these three workflows and manually execute them when needed. What should you do?
- A. Set up cron jobs in a Compute Engine instance to schedule and monitor the pipelines using GCP API calls.
- B. Create a Direct Acyclic Graph in Cloud Composer to schedule and monitor the jobs.
- C. Use Stackdriver Monitoring and set up an alert with a Webhook notification to trigger the jobs.
- D. Develop an App Engine application to schedule and request the status of the jobs using GCP API calls.
正解:A
質問 # 77
You work for a large fast food restaurant chain with over 400,000 employees. You store employee information in Google BigQuery in a Users table consisting of a FirstName field and a LastName field. A member of IT is building an application and asks you to modify the schema and data in BigQuery so the application can query a FullName field consisting of the value of the FirstName field concatenated with a space, followed by the value of the LastName field for each employee. How can you make that data available while minimizing cost?
- A. Add a new column called FullName to the Users tabl
- B. Use BigQuery to export the data for the table to a CSV fil
- C. Create a Google Cloud Dataflow job that queries BigQuery for the entire Users table, concatenates the FirstName value and LastName value for each user, and loads the proper values for FirstName, LastName, and FullName into a new table in BigQuery.
- D. Create a view in BigQuery that concatenates the FirstName and LastName field values to produce the FullName.
- E. Run an UPDATE statement that updates the FullName column for each user with the concatenation of the FirstName and LastName values.
- F. Create a Google Cloud Dataproc job to process the CSV file and output a new CSV file containing the proper values for FirstName, LastName and FullNam G. Run a BigQuery load job to load the new CSV file into BigQuery.
正解:E
