- A
Create the Bigtable instance with multi-region placement in europe-west1 and europe-west4.
Why wrong: Multi-region placement includes multiple regions, but some may be outside the EU? Actually europe-west1 and europe-west4 are both in EU, but multi-region is not recommended for strict residency; single region is safer.
- B
Create an instance in a dual-region configuration (e.g., europe-west1 and europe-west4) and use backup policies.
Why wrong: Dual-region is not a supported placement option for Bigtable; only single-region or multi-region are available.
- C
Use a single-region instance in europe-west1 with customer-managed encryption keys (CMEK) for backups.
Why wrong: CMEK does not affect data residency; backups are still stored in the same region.
- D
Create the Bigtable instance in a single EU region (e.g., europe-west1) and enable automatic backups.
Backups are stored in the same region as the instance, ensuring data stays in the EU.
PCSE Supporting compliance requirements Practice Question
This PCSE practice question tests your understanding of supporting compliance requirements. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 must implement data residency requirements that prohibit storing data outside the European Union. They are using Cloud Bigtable and need to ensure that backups are also stored within the EU. Which configuration should they choose?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Create the Bigtable instance in a single EU region (e.g., europe-west1) and enable automatic backups.
Option D is correct because a single-region Bigtable instance in an EU region (e.g., europe-west1) ensures that all data, including backups, remains within the EU. Enabling automatic backups stores backup data in the same region, satisfying data residency requirements that prohibit storing data outside the EU.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Create the Bigtable instance with multi-region placement in europe-west1 and europe-west4.
Why it's wrong here
Multi-region placement includes multiple regions, but some may be outside the EU? Actually europe-west1 and europe-west4 are both in EU, but multi-region is not recommended for strict residency; single region is safer.

Why it's wrong here
Dual-region is not a supported placement option for Bigtable; only single-region or multi-region are available.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that multi-region or dual-region configurations are acceptable for data residency, but the trap here is that any replication across regions (even within the EU) can violate strict data residency if the requirement prohibits storing data outside a specific geographic boundary, and backups must be explicitly confined to the same region.
Detailed technical explanation
How to think about this question
Bigtable backups are stored in the same region as the instance by default when using automatic backups, but manual backup policies can specify a different region. For strict data residency, a single-region instance with automatic backups ensures all data and backups remain within the chosen EU region, as Bigtable does not replicate data across regions in a single-region setup. This aligns with GDPR requirements where data must not leave the EU, even for backup copies.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
