Quick Answer
The answer is to create the BigQuery dataset with the location set to 'EU'. This is correct because BigQuery enforces data residency at the dataset level; once you specify a geographic location like 'EU', all tables, views, and imported data within that dataset are physically stored in a Google Cloud region inside the European Union, ensuring GDPR compliance by preventing automatic replication or movement of data outside that boundary. On the Google Professional Cloud Database Engineer exam, this tests your understanding that BigQuery’s location is immutable after creation and that GDPR data residency is satisfied by dataset-level configuration, not by table or query settings. A common trap is assuming you can set location at the project level or that BigQuery automatically geo-fences data without explicit action. Memory tip: think of the dataset as a locked container—set its region first, then fill it with data, and the data stays inside that container.
This PCDE practice question tests your understanding of plan and manage database infrastructure. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to store and analyze data with BigQuery. They have customers in Europe and need to comply with GDPR data residency requirements. What should they do to ensure data stays within the European Union?
Use the default dataset location and rely on BigQuery's automatic compliance.
Why wrong: Default location is 'US'.
Create the dataset with the location set to 'EU'.
Dataset location determines where data is stored.
Set the query job location to 'EU' for all queries.
Why wrong: Location only affects query processing, not storage.
Choose a dataset location of 'us-central1' for performance.
Why wrong: us-central1 is in the US, violating GDPR.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create the dataset with the location set to 'EU'.
Option B is correct because BigQuery enforces data residency at the dataset level. When you create a dataset with the location set to 'EU', all tables, views, and data within that dataset are physically stored in a Google Cloud region within the European Union. This ensures compliance with GDPR data residency requirements, as data will not be moved or replicated outside the EU without explicit user action.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Use the default dataset location and rely on BigQuery's automatic compliance.
Why it's wrong here
Default location is 'US'.
Create the dataset with the location set to 'EU'.
Why this is correct
Dataset location determines where data is stored.
Related concept

Set the query job location to 'EU' for all queries.
Why it's wrong here
Location only affects query processing, not storage.
Choose a dataset location of 'us-central1' for performance.
Why it's wrong here
us-central1 is in the US, violating GDPR.
Common exam traps
Google Cloud often tests the misconception that query job location controls data residency, when in fact it only controls query processing location, while data storage is determined by the dataset location.
Detailed technical explanation
BigQuery dataset locations are immutable after creation and determine the physical storage region for all data in that dataset. The 'EU' location encompasses multiple Google Cloud regions within the European Union (e.g., europe-west1, europe-west4), and data is stored redundantly within that multi-region. For GDPR compliance, it is critical to note that even if you set the query job location to 'EU', querying data stored in a US dataset will still process data in the US, and temporary results may be stored there, potentially violating residency requirements.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
