PDE Ingesting and Processing the Data Practice Question
You need to ingest Google Ads performance data into BigQuery on a daily basis for reporting. Which service should you use?
⚠ Common exam trap
Google often tests the distinction between fully managed services (like BigQuery Data Transfer Service) and generic infrastructure components (like Cloud Scheduler or Pub/Sub) that require custom development, leading candidates to overcomplicate the solution by choosing a more flexible but less appropriate option.

Correct answer & explanation
✓
BigQuery Data Transfer Service for Google Ads
The BigQuery Data Transfer Service for Google Ads is the correct choice because it provides a fully managed, scheduled connector that automatically ingests Google Ads performance data into BigQuery on a daily basis without requiring any custom code. It handles authentication, schema mapping, and incremental loads, making it the simplest and most reliable solution for this specific use case.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
BigQuery Data Transfer Service for Google Ads
Why this is correct
This service is specifically designed to import data from Google Ads into BigQuery on a scheduled basis.
- ✗
Cloud Scheduler to call Google Ads API and load to BigQuery
Why it's wrong here
Cloud Scheduler alone cannot authenticate to the Google Ads API or handle the OAuth2 token refresh required for programmatic data extraction; it merely triggers HTTP endpoints or Pub/Sub messages, lacking built-in integration with Google Ads. This option is tempting because Cloud Scheduler is commonly used to orchestrate periodic data loads into BigQuery via scheduled queries or Cloud Functions, and it would be correct if the data source exposed a simple REST endpoint without requiring custom authentication logic.
- ✗
Pub/Sub with a Google Ads subscriber
Why it's wrong here
Google Ads does not natively publish to Pub/Sub.
- ✗
Storage Transfer Service for Google Ads
Why it's wrong here
Storage Transfer Service is for cloud storage (GCS, S3, Azure Blob), not for Google Ads.
