MS-900 Public cloud Practice Question
While preparing a Microsoft 365 adoption plan, a consultant is asked to use provider-managed infrastructure shared by multiple customers. Cloud concept or benefit best matches this requirement?
⚠ Common exam trap
Test-takers frequently confuse a specific Microsoft 365 feature (like DLP or sensitivity labels) with a cloud deployment model, failing to recognize that the question is asking about the fundamental cloud concept of shared, provider-managed infrastructure, not a security or productivity tool.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Public cloud
The requirement for provider-managed infrastructure shared by multiple customers directly maps to the public cloud deployment model. In a public cloud, the cloud provider owns and manages the physical hardware, software, and supporting infrastructure, which is shared across multiple tenants (multi-tenancy). This is the core definition of public cloud as opposed to private or hybrid models.
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 cloud
Why this is correct
Public cloud delivers provider-managed compute, storage and networking shared across multiple tenants, exactly matching the shared-infrastructure requirement. Microsoft, Amazon and Google own and operate the hardware, so the organisation consumes pooled capacity rather than dedicated private resources.
- ✗
Data Loss Prevention (DLP)
Why it's wrong here
Data Loss Prevention is a compliance control that inspects and blocks sensitive data flows; it is unrelated to infrastructure ownership or tenancy. The described shared, provider-managed infrastructure is the public cloud deployment model. DLP would be the answer when the requirement concerns protecting sensitive information from exfiltration.
- ✗
Sensitivity labels
Why it's wrong here
Sensitivity labels classify and protect content with encryption and markings; they do not describe infrastructure ownership or tenancy. It is tempting because labels are central to Microsoft 365 information protection, but the shared, provider-managed resources in the stem describe the public cloud model, not labelling.
- ✗
Microsoft Planner
Why it's wrong here
Microsoft Planner is a task and plan collaboration tool for teams, not infrastructure. It cannot deliver provider-managed, multi-tenant compute or storage. The stem describes the public cloud deployment model, where a provider shares pooled infrastructure across customers; Planner would only be relevant when the requirement is organising project tasks and assignments.
