- A
Public cloud — all workloads run in a provider's infrastructure.
Why wrong: Public cloud means all resources are in the cloud provider's infrastructure. The hospital specifically keeps patient records on-premises, so this is not a pure public cloud model.
- B
Private cloud — all workloads run in the hospital's own infrastructure.
Why wrong: Private cloud means all computing happens in the hospital's owned/managed infrastructure. Using Google Cloud's AI services makes this a hybrid, not a pure private cloud.
- C
Hybrid cloud — combining on-premises infrastructure with public cloud services.
Hybrid cloud connects on-premises (patient records, regulatory compliance) with public cloud (AI imaging analysis). This is the textbook hybrid cloud pattern for regulated industries.
- D
Multi-cloud — using multiple public cloud providers simultaneously.
Why wrong: Multi-cloud refers to using multiple different public cloud providers (e.g., both Google Cloud and AWS). This scenario is on-premises + one cloud provider — hybrid, not multi-cloud.
What is a Hybrid Cloud Deployment Model?
This GCDL practice question tests your understanding of gcdl exam topics. 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 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?
Clue words in this question

"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Quick Answer
The answer is hybrid cloud, as this deployment model directly addresses the hospital’s need to keep sensitive patient records on-premises while leveraging public cloud AI for diagnostic imaging. Hybrid cloud uniquely combines private infrastructure for regulated data with public cloud services for compute-intensive tasks, ensuring data residency compliance without sacrificing scalability. On the Google Cloud Digital Leader exam, this scenario tests your understanding of how hybrid architectures solve real-world regulatory and workload-balancing challenges—a common trap is assuming “private cloud” fits, but private cloud alone cannot provide the public cloud’s AI services. Remember the memory tip: “Keep data home, compute in the cloud” to distinguish hybrid from private or public-only models.
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
Hybrid cloud — combining on-premises infrastructure with public cloud services.
The hospital must keep patient records on-premises to comply with data residency regulations, but wants to leverage cloud-based AI for diagnostic imaging. A hybrid cloud model combines on-premises infrastructure (for sensitive data) with public cloud services (for AI processing), allowing data to remain resident while compute-intensive tasks are offloaded. This matches the scenario exactly, as hybrid cloud enables workload distribution across private and public environments.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The GCDL exam often tests the misconception that 'hybrid cloud' requires equal distribution of workloads, but the trap here is that candidates may confuse 'multi-cloud' (multiple public providers) with 'hybrid cloud' (private + public), failing to recognize that on-premises infrastructure is a key component of hybrid cloud.

Scenario analysis trap

Detailed technical explanation
How to think about this question
In a hybrid cloud, connectivity between on-premises and public cloud is typically established via VPN tunnels (using IPsec/IKEv2) or dedicated circuits like AWS Direct Connect or Azure ExpressRoute, ensuring low-latency and secure data transfer. The AI imaging analysis can be performed in the public cloud using services like Amazon Rekognition or Google Cloud Healthcare API, while patient records remain on-premises, with only de-identified or encrypted metadata sent to the cloud. This architecture often leverages edge computing or local caching to minimize data exposure and comply with regulations like HIPAA or GDPR.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
