AZ-900 Describe Azure architecture and services Practice Question
This AZ-900 practice question tests your understanding of describe azure architecture and services. 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.
Which Azure service provides dedicated physical servers for regulatory or licensing requirements where hardware cannot be shared with other customers?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Dedicated Host
Azure Dedicated Host provides physical servers dedicated to a single Azure subscription, ensuring that hardware is not shared with other customers. This meets regulatory or licensing requirements that mandate hardware isolation, such as specific compliance standards or software licensing agreements that restrict usage to dedicated hardware.
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.
✗
Azure Reserved VM Instances
Why it's wrong here
Reserved Instances are a billing commitment on shared infrastructure, not physically dedicated servers.
✗
Azure Spot VMs
Why it's wrong here
Spot VMs are discounted unused capacity on shared infrastructure.
✓
Azure Dedicated Host
Why this is correct
Dedicated Host provides physical servers dedicated to one organization for compliance and licensing requirements.

✗
Azure Isolated VM sizes
Why it's wrong here
Isolated VM sizes are large SKUs isolated to a single customer workload but are not physically dedicated hosts.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Dedicated Host with Azure Isolated VM sizes, but Isolated VM sizes only guarantee isolation from other VM sizes on the same host, not a dedicated physical server, whereas Dedicated Host provides full physical server exclusivity.
Detailed technical explanation
How to think about this question
Azure Dedicated Hosts are mapped to a specific physical server in an Azure datacenter, and you control the maintenance windows and can place VMs directly on the host. This is critical for scenarios like Windows Server or SQL Server licensing that requires dedicated hardware to avoid per-core licensing costs across shared hosts, or for compliance frameworks like PCI-DSS that mandate physical isolation. Under the hood, each Dedicated Host is a hypervisor-managed physical node that is not shared with any other customer, and you can use Azure Hybrid Benefit to apply your own licenses.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
