A marketing analyst needs to query sales data stored in BigQuery to find the top 10 products by revenue for the last quarter.

Which tool and approach should they use?

A) Write a SQL query in the BigQuery console using GROUP BY, ORDER BY, and LIMIT clauses on the sales table
B) Export all data to a spreadsheet and manually sort it
C) Use Cloud Storage to search through raw data files
D) Ask the data engineering team to build a custom application for this one query

 

Correct answers: A – Explanation:
BigQuery SQL provides direct, fast querying of large datasets with standard SQL. Spreadsheet export is impractical for large datasets. Cloud Storage stores files but does not query them. A custom application is overkill for a standard SQL query.

A data practitioner needs to ingest CSV files uploaded daily by a partner into Cloud Storage and make them available for analysis in BigQuery.

Which approach automates this ingestion pipeline?

A) Configure a Cloud Storage event trigger that activates a Dataflow or Cloud Function to load the CSV into BigQuery automatically
B) Manually uploading each CSV to BigQuery through the console daily
C) Emailing the partner to upload directly to BigQuery
D) Processing CSVs only once a month in a batch job

 

Correct answers: A – Explanation:
Event-triggered automation loads data immediately upon upload without manual intervention. Manual daily uploads do not scale. Partners typically cannot access BigQuery directly. Monthly batch processing introduces unacceptable delay for daily data.

A business analyst wants to create an interactive dashboard showing regional sales performance that automatically refreshes with the latest BigQuery data.

Which Google Cloud tool should they use for visualization?

A) Looker or Looker Studio connected to BigQuery as the data source
B) Exporting data to CSV and creating charts in a local spreadsheet weekly
C) Building a custom web application with Chart.js
D) Using Cloud Monitoring dashboards designed for infrastructure metrics

 

Correct answers: A – Explanation:
Looker and Looker Studio provide interactive, auto-refreshing dashboards connected directly to BigQuery. CSV exports become stale immediately. Custom web apps require development effort. Cloud Monitoring is for infrastructure, not business analytics.

A data practitioner discovers that incoming data contains duplicate records, missing values, and inconsistent date formats that need to be cleaned before analysis.

Which Google Cloud tool should they use for data preparation?

A) Dataprep by Trifacta (now Dataform or Dataflow) for visual data cleaning, deduplication, and format standardization
B) Loading raw data directly into BigQuery without any cleaning
C) Manually editing each record in a spreadsheet
D) Using Cloud DNS to validate data quality

 

Correct answers: A – Explanation:
Dataprep provides visual data wrangling for cleaning, deduplication, and standardization. Loading raw data pollutes the analytics environment. Manual editing does not scale. Cloud DNS manages domain names, not data quality.

A team needs to understand how website visitors move through their checkout funnel and where they drop off.

Which Google Cloud and analytics tools should be used?

A) Google Analytics 4 for funnel analysis combined with BigQuery export for deeper custom analysis
B) Cloud Monitoring for tracking user behavior on the website
C) Cloud Logging for analyzing web server access logs only
D) Bigtable for storing clickstream events without analysis tools

 

Correct answers: A – Explanation:
GA4 provides funnel analysis and BigQuery export enables custom deep analysis. Cloud Monitoring tracks infrastructure, not user behavior. Access logs alone lack session and funnel context. Bigtable stores data but provides no built-in analysis.

A data practitioner needs to apply basic machine learning to predict customer churn without writing ML code.

Which Google Cloud approach enables this?

A) BigQuery ML to train a classification model using SQL on customer data already in BigQuery
B) Building a custom TensorFlow model from scratch
C) Using Cloud Vision API for churn prediction
D) Manual analysis of customer records to identify patterns

 

Correct answers: A – Explanation:
BigQuery ML allows SQL-based model training directly on BigQuery data without ML coding. Custom TensorFlow requires ML expertise. Cloud Vision analyzes images, not customer churn. Manual analysis does not scale and misses complex patterns.

A company needs to ensure that their data in BigQuery follows governance standards with proper access controls, data cataloging, and lineage tracking.

Which Google Cloud services support data governance?

A) Dataplex for data governance with automated data quality checks, and Data Catalog for metadata management and discovery
B) Granting all employees BigQuery Admin access for transparency
C) Storing governance documentation in a Google Doc
D) Ask the data engineering team to build a custom application for this one query

 

Correct answers: A – Explanation:
Dataplex and Data Catalog provide comprehensive governance with quality checks, cataloging, lineage, and access controls. Universal admin access violates governance principles. Documentation alone does not enforce governance. Storage access logs are insufficient for full data governance.

A data practitioner needs to join customer data from a Cloud SQL database with transaction data in BigQuery for a unified customer analysis.

How should they combine these two data sources?

A) Use BigQuery federated queries to query Cloud SQL directly from BigQuery, or use a Dataflow pipeline to load Cloud SQL data into BigQuery
B) Manually exporting both datasets to CSV and joining them in a spreadsheet
C) Creating a VPC peering connection and assuming the data automatically merges
D) Replacing Cloud SQL with Bigtable for all data

 

Correct answers: A – Explanation:
BigQuery SQL provides direct, fast querying of large datasets with standard SQL. Spreadsheet export is impractical for large datasets. Cloud Storage stores files but does not query them. A custom application is overkill for a standard SQL query.

A sales team needs a scheduled email report showing weekly revenue summaries from BigQuery data.

Which approach delivers automated scheduled reports?

A) Looker Studio with scheduled email delivery of the report configured on a weekly cadence
B) Manually running a query and emailing results every Monday
C) Building a custom application to generate and send reports
D) Using Cloud Pub/Sub to stream revenue data to email

 

Correct answers: A – Explanation:
Looker Studio scheduled delivery automates weekly report distribution. Manual query and email is not scalable. Custom applications add unnecessary development. Pub/Sub is for messaging between services, not formatted email reports.

A data practitioner needs to understand the quality of their dataset including completeness, uniqueness, and consistency before using it for analysis.

Which approach should they take to assess data quality?

A) Use Dataplex data quality rules or run profiling queries in BigQuery to assess completeness, uniqueness, and value distributions
B) Assume the data is clean because it comes from a trusted source
C) Check only the first 10 rows of data manually
D) Wait for analysts to report data issues after using it in reports

 

Correct answers: A – Explanation:
Dataplex quality rules and BigQuery profiling provide systematic data quality assessment. Assuming cleanliness risks analysis errors. Checking 10 rows misses issues in the full dataset. Waiting for downstream reports delays issue detection.
