This AZ-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 company runs a workload that requires predictable performance and dedicated physical servers. They also need to ensure no other tenant uses the same hardware. Which cloud deployment model meets these requirements?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Private
A private cloud deployment model is correct because it provides dedicated physical servers and ensures that no other tenant shares the same hardware. In a private cloud, the infrastructure is provisioned for exclusive use by a single organization, offering predictable performance and complete isolation from other tenants. This model can be hosted on-premises or by a third-party provider, but the key requirement of dedicated hardware is met.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Public
Why it's wrong here
Public clouds use multi-tenant infrastructure, where hardware is shared. This does not guarantee dedicated servers or isolation.
✓
Private
Why this is correct
A private cloud provides exclusive use of infrastructure for one customer, offering dedicated physical servers and full control.

✗
Hybrid
Why it's wrong here
Hybrid combines public and private, but the requirement for dedicated hardware points to a fully private environment.
✗
Community
Why it's wrong here
A community cloud is shared among several organizations with similar concerns, not dedicated to a single tenant.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'dedicated hardware' with a hybrid cloud, thinking it combines the best of both worlds, but hybrid still relies on public cloud resources that are multi-tenant by default.

Detailed technical explanation
How to think about this question
Under the hood, private cloud environments often leverage hypervisors like VMware vSphere or Microsoft Hyper-V with features such as CPU pinning and memory reservation to ensure dedicated resource allocation. In a real-world scenario, a financial institution running PCI DSS-compliant workloads would use a private cloud to maintain strict hardware isolation and predictable performance, avoiding the noisy-neighbor effect common in public clouds. The dedicated physical servers are typically managed via Infrastructure-as-a-Service (IaaS) with no virtualization layer sharing.

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
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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
