Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A financial services company must migrate a critical application to Azure. Regulatory compliance requires that the virtual machines (VMs) hosting this application run on physical servers that are dedicated solely to the company and not shared with any other Azure customer. The company needs full control over server hardware maintenance, including the ability to schedule updates and isolate the environment at the physical layer. Which Azure compute solution should the company use?
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
Azure Dedicated Host
Azure Dedicated Host provides physical servers dedicated to one Azure subscription. VMs are isolated at the hardware level, and the customer controls maintenance and scheduling. This fully satisfies the compliance requirement for physical server isolation.
B
Distractor review
Azure Reserved Instances
Reserved Instances are a billing and pricing model that offers discounted rates in exchange for a one- or three-year commitment. They do not provide any physical server isolation; VMs purchased under Reserved Instances may still run on shared physical hardware.
C
Distractor review
Azure Virtual Machine Scale Sets
Virtual Machine Scale Sets allow you to deploy and manage a group of identical, load-balanced VMs that can scale in or out automatically. They do not guarantee that the VMs are placed on a dedicated physical host; the underlying hardware may be shared with other tenants.
D
Distractor review
Azure Confidential Computing
Confidential computing protects data in use by using hardware-based trusted execution environments (e.g., Intel SGX). While this provides strong data encryption during processing, it does not ensure that the entire physical server is dedicated to a single customer. Multiple tenants' VMs using confidential computing can still reside on the same physical host.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

FAQ
Questions learners often ask
What does this AZ-900 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Azure Dedicated Host — Azure Dedicated Host provides dedicated physical servers that host one or more Azure VMs. This ensures that the physical server is not shared with other customers, meeting strict isolation and compliance requirements. The customer has control over maintenance events and can schedule updates. Reserved Instances offer discounted pricing but no physical isolation. Virtual Machine Scale Sets provide auto-scaling and load balancing across a set of VMs but do not guarantee physical server exclusivity. Confidential computing protects data in use through hardware-based trusted execution environments but does not guarantee that the underlying physical server is dedicated to a single customer.
