AZ-900 Describe cloud concepts Practice Question
A company is moving its on-premises data center to the cloud. Previously, they purchased servers and paid for maintenance. Now they pay a monthly subscription for compute and storage based on actual usage. This is an example of shifting from capital expenditure (CapEx) to which type of expenditure?
⚠ Common exam trap
Watch out — candidates often confuse 'variable expenditure' with OpEx because cloud costs can fluctuate, but the exam specifically tests the accounting distinction between CapEx (upfront capital) and OpEx (ongoing operational costs) as defined in Microsoft's cloud economics model.
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
✓
Operating expenditure (OpEx)
This scenario describes a shift from upfront capital investment in physical servers and maintenance (CapEx) to a pay-as-you-go model where costs are incurred based on actual usage. In cloud computing, this is the definition of operating expenditure (OpEx), as the company pays a recurring monthly subscription for compute and storage resources rather than making a large initial purchase.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Operating expenditure (OpEx)
Why this is correct
Operating expenditure (OpEx) represents the ongoing, pay-as-you-go costs incurred for consuming cloud services, such as per-second virtual machine uptime or per-GB storage fees. Unlike traditional capital expenditures on hardware with finite depreciation cycles, OpEx scales directly with usage and requires no upfront procurement. Azure bills monthly, enabling predictable cost forecasting and alignment of IT costs with business consumption.
- ✗
Variable expenditure
Why it's wrong here
Variable expenditure is not a standalone cost category; instead, it describes a key attribute of operating expenditure—the cost fluctuates in proportion to usage. While cloud costs are indeed variable because you pay for exactly what you consume, the question asks for the overarching financial model, not a descriptive characteristic. Thus, 'variable expenditure' is a component nuance of OpEx rather than a correct answer on its own.
When this WOULD be correct
If a question asked 'Which type of cost changes based on usage in a pay-as-you-go model?' then 'Variable expenditure' would be correct, as it directly describes costs that fluctuate with consumption.
- ✗
Direct expenditure
Why it's wrong here
Direct expenditure is an accounting term for costs traceable to a specific cost object, such as materials or labor for a product line, rather than a cloud financial classification. In Azure cost management, expenditures are categorized as operating, capital, or by resource tags, but not as 'direct' or 'indirect' in the cloud billing sense. Choosing this option confuses conventional managerial accounting labels with the cloud's consumption-based OpEx model.
When this WOULD be correct
A question asking about costs that can be directly attributed to a specific product or service, such as raw materials or labor, where 'direct expenditure' is the correct accounting term.
- ✗
Indirect expenditure
Why it's wrong here
Indirect expenditure refers to overhead costs not directly attributable to a single product or service, such as administrative salaries or facility maintenance. In a cloud context, the billing statement reflects directly consumed services linked to specific subscriptions and resources, not pooled overhead. Therefore, classifying cloud usage as indirect expenditure mislabels the direct, metered relationship between resource consumption and cost.
When this WOULD be correct
A question asks: 'A company pays for cloud services but also incurs costs for office rent and electricity. Which type of expenditure are the rent and electricity?' In that context, indirect expenditure would be correct.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-900 exam frequently reuses these exact scenarios with slightly different constraints.
✓Operating expenditure (OpEx)Correct answer▾
Why this is correct
Operating expenditure (OpEx) represents the ongoing, pay-as-you-go costs incurred for consuming cloud services, such as per-second virtual machine uptime or per-GB storage fees. Unlike traditional capital expenditures on hardware with finite depreciation cycles, OpEx scales directly with usage and requires no upfront procurement. Azure bills monthly, enabling predictable cost forecasting and alignment of IT costs with business consumption.
✗Variable expenditureWrong answer — click to see why▾
Why this is wrong here
In cloud cost models, 'variable expenditure' is not a standard accounting term; the correct contrast to CapEx is OpEx, which includes variable costs but also other operational costs.
★ When this WOULD be the correct answer
If a question asked 'Which type of cost changes based on usage in a pay-as-you-go model?' then 'Variable expenditure' would be correct, as it directly describes costs that fluctuate with consumption.
Why candidates choose this
Candidates may think 'variable expenditure' fits because cloud costs vary with usage, but they overlook that the standard financial classification is CapEx vs. OpEx, not variable vs. fixed.
✗Direct expenditureWrong answer — click to see why▾
Why this is wrong here
In cloud economics, 'direct expenditure' is not a standard category for comparing CapEx and OpEx; the correct term for pay-as-you-go cloud costs is operating expenditure (OpEx).
★ When this WOULD be the correct answer
A question asking about costs that can be directly attributed to a specific product or service, such as raw materials or labor, where 'direct expenditure' is the correct accounting term.
Why candidates choose this
Candidates may confuse 'direct expenditure' with the direct costs of cloud services, not realizing that the CapEx-to-OpEx shift is the specific focus of the question.
✗Indirect expenditureWrong answer — click to see why▾
Why this is wrong here
Indirect expenditure refers to costs not directly tied to a specific product or service, like utilities or rent. The question describes a shift from CapEx to a usage-based subscription model, which is OpEx, not indirect expenditure.
★ When this WOULD be the correct answer
A question asks: 'A company pays for cloud services but also incurs costs for office rent and electricity. Which type of expenditure are the rent and electricity?' In that context, indirect expenditure would be correct.
Why candidates choose this
Candidates may confuse 'indirect' with 'operating' because both are ongoing costs, but indirect expenditure is a subset of OpEx that is not directly attributable to a specific cost object.

What is Cloud Computing?
Key term
OpEx
Operational Expenditure (OpEx) is the ongoing cost for running a business, like paying for cloud services monthly instead of buying hardware upfront.
Key term
CapEx
CapEx (Capital Expenditure) is the money a company spends upfront to buy, build, or improve physical assets like servers, buildings, or equipment, which are then owned and depreciated over time.
