Question 3

Your company is building a near real-time streaming pipeline to process JSON telemetry data from small appliances. You need to process messages arriving at a Pub/Sub topic, capitalize letters in the
serial number field, and write results to BigQuery. You want to use a managed service and write a
minimal amount of code for underlying transformations. What should you do?

Accepted Answer

Use the “Pub/Sub to BigQuery” Dataflow template with a UDF, and write the results to BigQuery.

Answer

Use a Pub/Sub to BigQuery subscription, write results directly to BigQuery, and schedule a transformation query to run every five minutes.

Answer

Use a Pub/Sub to Cloud Storage subscription, write a Cloud Run service that is triggered when objects arrive in the bucket, performs the transformations, and writes the results to BigQuery.

Answer

Use a Pub/Sub push subscription, write a Cloud Run service that accepts the messages, performs the transformations, and writes the results to BigQuery.

Question 4

You want to process and load a daily sales CSV file stored in Cloud Storage into BigQuery for downstream reporting. You need to quickly build a scalable data pipeline that transforms the data
while providing insights into data quality issues. What should you do?

Accepted Answer

Create a batch pipeline in Cloud Data Fusion by using a Cloud Storage source and a BigQuery sink.

Answer

Load the CSV file as a table in BigQuery, and use scheduled queries to run SQL transformation scripts.

Answer

Load the CSV file as a table in BigQuery. Create a batch pipeline in Cloud Data Fusion by using a BigQuery source and sink.

Answer

Create a batch pipeline in Dataflow by using the Cloud Storage CSV file to BigQuery batch template.

Question 5

You manage a Cloud Storage bucket that stores temporary files created during data processing. These temporary files are only needed for seven days, after which they are no longer needed. To reduce
storage costs and keep your bucket organized, you want to automatically delete these files once they
are older than seven days. What should you do?

Accepted Answer

Configure a Cloud Storage lifecycle rule that automatically deletes objects older than seven days.

Answer

Set up a Cloud Scheduler job that invokes a weekly Cloud Run function to delete files older than seven days.

Answer

Develop a batch process using Dataflow that runs weekly and deletes files based on their age.

Answer

Create a Cloud Run function that runs daily and deletes files older than seven days.

Question 6

You work for a healthcare company that has a large on-premises data system containing patient records with personally identifiable information (PII) such as names, addresses, and medical
diagnoses. You need a standardized managed solution that de-identifies PII across all your data feeds
prior to ingestion to Google Cloud. What should you do?

Accepted Answer

Use Cloud Data Fusion to transform the data. Store the cleaned data in BigQuery.

Answer

Use Cloud Run functions to create a serverless data cleaning pipeline. Store the cleaned data in BigQuery.

Answer

Load the data into BigQuery, and inspect the data by using SQL queries. Use Dataflow to transform the data and remove any errors.

Answer

Use Apache Beam to read the data and perform the necessary cleaning and transformation operations. Store the cleaned data in BigQuery.

Question 7

You manage a large amount of data in Cloud Storage, including raw data, processed data, and backups. Your organization is subject to strict compliance regulations that mandate data immutability
for specific data types. You want to use an efficient process to reduce storage costs while ensuring
that your storage strategy meets retention requirements. What should you do?

Accepted Answer

Use object holds to enforce immutability for specific objects, and configure lifecycle management rules to transition objects to appropriate storage classes based on age and access patterns.

Answer

Configure lifecycle management rules to transition objects to appropriate storage classes based on access patterns. Set up Object Versioning for all objects to meet immutability requirements.

Answer

Move objects to different storage classes based on their age and access patterns. Use Cloud Key Management Service (Cloud KMS) to encrypt specific objects with customer-managed encryption keys (CMEK) to meet immutability requirements.

Answer

Create a Cloud Run function to periodically check object metadata, and move objects to the appropriate storage class based on age and access patterns. Use object holds to enforce immutability for specific objects.

Question 8

You work for an ecommerce company that has a BigQuery dataset that contains customer purchase history, demographics, and website interactions. You need to build a machine learning (ML) model to
predict which customers are most likely to make a purchase in the next month. You have limited
engineering resources and need to minimize the ML expertise required for the solution. What should
you do?

Accepted Answer

Use BigQuery ML to create a logistic regression model for purchase prediction.

Answer

Use Vertex AI Workbench to develop a custom model for purchase prediction.

Answer

Use Colab Enterprise to develop a custom model for purchase prediction.

Answer

Export the data to Cloud Storage, and use AutoML Tables to build a classification model for purchase prediction.

Question 9

You are designing a pipeline to process data files that arrive in Cloud Storage by 3:00 am each day. Data processing is performed in stages, where the output of one stage becomes the input of the next.
Each stage takes a long time to run. Occasionally a stage fails, and you have to address
the problem. You need to ensure that the final output is generated as quickly as possible. What
should you do?

Accepted Answer

Design the processing as a directed acyclic graph (DAG) in Cloud Composer. Clear the state of the failed task after correcting any stage output data errors.

Answer

Design a Spark program that runs under Dataproc. Code the program to wait for user input when an error is detected. Rerun the last action after correcting any stage output data errors.

Answer

Design the pipeline as a set of PTransforms in Dataflow. Restart the pipeline after correcting any stage output data errors.

Answer

Design the workflow as a Cloud Workflow instance. Code the workflow to jump to a given stage based on an input parameter. Rerun the workflow after correcting any stage output data errors.

Question 10

Another team in your organization is requesting access to a BigQuery dataset. You need to share the dataset with the team while minimizing the risk of unauthorized copying of dat
a. You also want to create a reusable framework in case you need to share this data with other teams
in the future. What should you do?

Accepted Answer

Create a private exchange using Analytics Hub with data egress restriction, and grant access to the team members.

Answer

Create authorized views in the team’s Google Cloud project that is only accessible by the team.

Answer

Enable domain restricted sharing on the project. Grant the team members the BigQuery Data Viewer IAM role on the dataset.

Answer

Export the dataset to a Cloud Storage bucket in the team’s Google Cloud project that is only accessible by the team.
