GCDL Practice Question: A hospital network wants to improve patient…
This GCDL practice question tests your understanding of a hospital network wants to improve patient…. 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 hospital network wants to improve patient outcomes by sharing medical records across its 12 hospitals so that any physician can access a patient's complete history. Currently, each hospital has its own isolated system. Which cloud characteristic is most relevant to enabling this cross-hospital data sharing?
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
Best answer
Cloud's ubiquitous network access, enabling a secure shared data platform accessible to authorized physicians across all 12 hospital locations through standard internet connectivity
Ubiquitous network access (one of NIST's cloud characteristics) is directly applicable. A shared cloud-hosted medical records platform makes patient data accessible to authorized physicians from any hospital location — exactly solving the isolated system problem.
B
Distractor review
Cloud resource pooling, which allows multiple hospitals to share physical compute resources
Resource pooling is the provider-side characteristic of shared infrastructure. While relevant to how cloud works technically, it's not the characteristic that directly enables cross-hospital data sharing for physicians.
C
Distractor review
Cloud elasticity, which allows the hospital to scale up server capacity during peak admission periods
Elasticity addresses capacity scaling, not data accessibility across locations. The specific barrier described — data isolated in 12 separate systems — requires shared, accessible data infrastructure, not elastic compute.
D
Distractor review
Cloud's pay-per-use billing model, which reduces the cost of medical record storage
Cost reduction through pay-per-use is a financial benefit. The primary barrier described is data accessibility across 12 locations, not storage cost. Solving the access problem is the priority.
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: Cloud's ubiquitous network access, enabling a secure shared data platform accessible to authorized physicians across all 12 hospital locations through standard internet connectivity — Cloud's accessibility and connectivity characteristics enable data to be available from any location through secure internet access. By consolidating patient records in a shared cloud platform, authorized physicians at any of the 12 hospitals can access the complete patient history. Cloud provides the secure, accessible, centralized data layer that isolated on-premises systems cannot achieve across a distributed network of facilities.
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.
