GCDL Practice Question: A hospital runs a patient records system that…
This GCDL practice question tests your understanding of a hospital runs a patient records system that…. 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?
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
Public cloud — all workloads run in a provider's infrastructure.
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
Distractor review
Multi-cloud — using multiple public cloud providers simultaneously.
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.
C
Distractor review
Private cloud — all workloads run in the hospital's own infrastructure.
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.
D
Best answer
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.
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
What is virtualization in the context of cloud computing, and why is it fundamental to how cloud providers deliver services?
Question 6
Which term describes the model where the cloud provider is responsible for the security of the cloud infrastructure, while the customer is responsible for security within their own cloud environment (data, applications, access management)?

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: Hybrid cloud — combining on-premises infrastructure with public cloud services. — A hybrid cloud model combines on-premises infrastructure with one or more public cloud services, connected and managed as a unified environment. The hospital keeps regulated data on-premises (meeting residency requirements) while leveraging cloud AI capabilities for computation that doesn't involve storing regulated data. This is the defining use case for hybrid cloud — regulatory or latency constraints keep some workloads on-premises while cloud handles others.
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.
