This GCDL practice question tests your understanding of a multinational company must ensure that personal…. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 multinational company must ensure that personal data of European citizens stored in Google Cloud cannot be accessed by or transferred to systems outside the European Union, as required by GDPR data residency requirements. Which Google Cloud controls most directly enforce this?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Enabling HTTPS for all data transmission to ensure data is encrypted during transfer
HTTPS encryption protects data in transit but doesn't restrict where data is stored or to which regions it can be transferred. GDPR residency requirements are about data location, not transmission encryption.
B
Distractor review
Training developers about GDPR requirements and requiring manual approval for any cross-region data transfers
Training and manual approval processes are procedural controls that are easily bypassed and don't scale. Technical controls (org policy, VPC Service Controls) enforce requirements automatically and reliably.
C
Distractor review
Using Customer-Managed Encryption Keys (CMEK) where the encryption keys are stored outside Google's infrastructure
CMEK gives customers control over encryption keys but doesn't prevent data from being stored or accessed in non-EU regions. Key management location is separate from data location — CMEK doesn't enforce geographic data residency.
D
Best answer
Configuring organization policy to restrict resource creation to EU regions, using VPC Service Controls to prevent data movement outside the EU perimeter, and establishing a GDPR-compliant Data Processing Agreement with Google
This combination addresses GDPR data residency: org policy constraints prevent resources from being created outside EU regions; VPC Service Controls prevent data from being read out of the EU perimeter; the DPA provides contractual compliance assurance. Together they form a comprehensive GDPR data residency control framework.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Question 1
A traditional retailer currently maintains its own data centers, purchasing servers every 3–5 years and paying for facilities, power, and staff regardless of demand. When it migrates its workloads to the public cloud, which change in cost model does it experience?
Question 2
An e-commerce company plans its infrastructure for peak shopping events (e.g., Black Friday) which drive 50× normal traffic. On-premises, they must maintain 50× capacity year-round. In the cloud, they provision 50× capacity only during peak periods. Which cloud characteristic enables this cost optimization?
Question 3
Which term describes the process by which organizations integrate digital technology into all areas of their business, fundamentally changing how they operate and deliver value to customers?
Question 4
When a company moves from maintaining its own data center to using Google Cloud, which operational responsibility does Google assume that the company previously managed?
Question 5
A hospital runs a patient records system that must remain on-premises due to strict regulatory data residency requirements. However, they also want to use cloud-based AI for diagnostic imaging analysis. Which cloud deployment model best describes their architecture?
Question 6
What is virtualization in the context of cloud computing, and why is it fundamental to how cloud providers deliver services?

FAQ
Questions learners often ask
What does this GCDL question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Configuring organization policy to restrict resource creation to EU regions, using VPC Service Controls to prevent data movement outside the EU perimeter, and establishing a GDPR-compliant Data Processing Agreement with Google — GDPR data residency requirements can be addressed through Google Cloud's combination of: regional resource constraints (org policy to restrict resource creation to EU regions), VPC Service Controls (prevent data movement outside the perimeter), and contractual frameworks (Data Processing Agreement with Google). These controls together ensure data stays in specified EU regions and cannot be transferred outside the perimeter.
What should I do if I get this GCDL question wrong?
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related GCDL NAT questions on configuration and troubleshooting.
