This MS-900 practice question tests your understanding of describe cloud concepts. 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 needs to ensure patient data remains in a specific geographic region due to regulatory requirements. Which cloud deployment model should they consider?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Private cloud
Option C is correct because a private cloud is dedicated to a single organization and can be deployed on-premises or in a datacenter, ensuring data residency and compliance. Option A (Public cloud) may store data across regions. Option B (Hybrid cloud) combines public and private but doesn't guarantee data stays in one region. Option D (Community cloud) is shared by several organizations, not ideal for strict data residency.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Community cloud
Why it's wrong here
Community cloud is shared among organizations with similar interests, but may not guarantee regional data control.
✓
Private cloud
Why this is correct
Private cloud is dedicated to a single organization, allowing full control over data location and compliance.
Related concept
Static NAT maps one inside address to one outside address.
✗
Hybrid cloud
Why it's wrong here
Hybrid cloud mixes public and private, but data could still be stored in public cloud regions.
✗
Public cloud
Why it's wrong here
Public cloud may have data centers in multiple regions, making it harder to guarantee data stays in one specific region.
Common exam traps
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.

Detailed technical explanation
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.
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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
