MS-900 Operational expenditure (OpEx) Practice Question
While preparing a Microsoft 365 adoption plan, a consultant is asked 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 'operational expenditure' with a specific tool or feature (like Planner or DLP) because they focus on the word 'plan' in the question, rather than recognizing that OpEx is a fundamental cloud financial model distinct from any product or security feature.

Correct answer & explanation
✓
Operational expenditure (OpEx) model
The operational expenditure (OpEx) model is correct because it aligns with the requirement to avoid upfront capital investment (CapEx) and instead pay monthly based on usage. In Microsoft 365, this is delivered through subscription-based licensing (e.g., per-user per-month plans), which shifts costs from large upfront server purchases to predictable monthly payments that scale with 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 apply encryption and marking to files and emails; they do not remove server purchases or introduce consumption-based charging. It is tempting because labelling underpins Microsoft 365 information protection, and would be correct if the requirement were classifying and protecting documents across workloads.
- ✗
Data Loss Prevention (DLP)
Why it's wrong here
Data Loss Prevention inspects and blocks sensitive data flows; it neither provisions compute nor converts capital expenditure into monthly usage-based billing. It is tempting because DLP is a cloud security capability, but the stated requirement describes the consumption-based pricing model, which is pay-as-you-go.
- ✓
Operational expenditure (OpEx) model
Why this is correct
The OpEx model satisfies the requirement to avoid upfront server purchases by shifting costs to monthly, usage-based payments. Unlike capital expenditure, which demands significant initial hardware investment, OpEx aligns spending with consumption, directly matching the consultant's mandate to eliminate upfront infrastructure costs while maintaining Microsoft 365 services.
- ✗
Microsoft Planner
Why it's wrong here
Microsoft Planner organises team tasks into buckets and charts; it has no bearing on infrastructure ownership or pay-as-you-go billing. It is tempting because it appears in adoption and rollout planning, and would be the right answer if the requirement were tracking deployment tasks and assigning owners.
