MS-900 Describe cloud concepts Practice Question
An administrator is reviewing a request from users who need to avoid buying servers upfront and pay monthly based on usage. Cloud concept or benefit best matches this requirement?
⚠ Common exam trap
It's easy for candidates to confuse OpEx with other cloud benefits like scalability or elasticity, but the question specifically tests the financial distinction between paying upfront (CapEx) versus paying monthly based on usage (OpEx).

Correct answer & explanation
✓
Operational expenditure (OpEx) model
The requirement to avoid upfront server purchases and pay monthly based on usage directly aligns with the operational expenditure (OpEx) model, a key cloud computing benefit. In cloud services, OpEx shifts costs from capital expenditure (CapEx) to a pay-as-you-go or subscription-based model, eliminating the need for large upfront hardware investments. This is a fundamental concept in Microsoft Azure and other cloud platforms, where resources like virtual machines are billed monthly based on actual consumption.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Sensitivity labels
Why it's wrong here
Sensitivity labels are Microsoft 365 compliance features that apply classification and encryption to documents and emails, controlling who can access and use content. They enforce governance and data protection policies but have no bearing on how compute resources are procured or paid for. Labeling content does not shift infrastructure costs from capital purchases to operational spending, so it does not help users avoid buying servers.
- ✗
Data Loss Prevention (DLP)
Why it's wrong here
Data Loss Prevention (DLP) monitors content across Exchange, SharePoint, OneDrive, and endpoints to detect and block accidental sharing of sensitive data such as Social Security numbers or credit card details. It implements security and compliance rules, but it neither provides compute capacity nor changes the financial model of IT procurement. DLP is irrelevant to the operational spending model that lets organizations lease cloud services instead of purchasing servers.
- ✓
Operational expenditure (OpEx) model
Why this is correct
The operational expenditure (OpEx) model charges for cloud solutions on a subscription or pay-as-you-go basis, so organizations pay a recurring fee for capacity instead of making a large upfront capital investment in hardware. Microsoft 365, for example, typically costs per user per month, covering licensing, maintenance, and infrastructure. This approach directly aligns with the users' need to avoid buying servers because it converts fixed capital expenditure into variable operating expenses that scale with actual usage.
- ✗
Microsoft Planner
Why it's wrong here
Microsoft Planner is a teamwork tool for organizing projects with boards, buckets, and assignments within Microsoft 365. It helps users manage work and deadlines but has nothing to do with cost management, infrastructure procurement, or the financial arrangements for cloud services. Selecting Planner as the reason for avoiding server purchases confuses a productivity feature with a business model.
