AZ-900 Describe cloud concepts Practice Question
A company is considering moving its IT infrastructure to the cloud. The CFO wants to understand the financial impact: instead of purchasing servers and paying for maintenance, the company will pay a monthly fee based on usage. This shift represents moving from which type of expenditure to which?
⚠ Common exam trap
Watch out — candidates often confuse the financial terms and select 'From OpEx to CapEx' (Option B) because they mistakenly think cloud costs are capital expenses due to long-term commitments like Reserved Instances, but the core shift is from upfront hardware purchases (CapEx) to ongoing service payments (OpEx).

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
From capital expenditure (CapEx) to operational expenditure (OpEx)
This shift represents moving from capital expenditure (CapEx) to operational expenditure (OpEx). CapEx involves upfront costs for physical assets like servers, which depreciate over time, while OpEx involves ongoing, usage-based payments for cloud services. In Azure, this aligns with the consumption-based model where you pay only for resources consumed (e.g., VM hours, storage GBs), eliminating large initial investments and shifting financial risk to the provider.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
From capital expenditure (CapEx) to operational expenditure (OpEx)
Why this is correct
This is the classic financial model shift in cloud computing, where upfront hardware costs are replaced by ongoing operational costs. Instead of purchasing servers and data center equipment, organizations pay for compute, storage, and services on a pay-as-you-go basis. This allows for better cash-flow predictability and eliminates the need for depreciation accounting.
- ✗
From operational expenditure (OpEx) to capital expenditure (CapEx)
Why it's wrong here
This is the opposite of the financial impact of cloud adoption. Moving to the cloud minimizes capital expenditure by eliminating the need to purchase physical infrastructure, which is a CapEx item. Instead, recurring subscription and consumption charges appear as operational expenditure. Therefore, the direction is from CapEx to OpEx, making this option incorrect.
When this WOULD be correct
This option would be correct if a company moves from a pay-as-you-go cloud model (OpEx) to purchasing on-premises hardware (CapEx), e.g., migrating from cloud back to on-premises to reduce ongoing costs.
- ✗
From direct expenditure to indirect expenditure
Why it's wrong here
Direct versus indirect expenditure is not a classification used in cloud migration planning. The relevant categories are capital expenditure (CapEx) for upfront assets and operational expenditure (OpEx) for ongoing service fees. Cloud costs are directly attributable to usage, but the core financial transformation is between CapEx and OpEx, not between direct and indirect cost accounting.
When this WOULD be correct
A question asks: 'A company pays for cloud services directly from its IT budget, while office rent is allocated across departments. This represents moving from which type of expenditure to which?' The answer would be from indirect expenditure to direct expenditure.
- ✗
From variable expenditure to fixed expenditure
Why it's wrong here
This option reverses the actual change. On-premises IT typically involves fixed costs such as hardware purchases and annual software licenses, regardless of utilization. In the cloud, spending becomes variable, scaling with the amount of resources consumed. Thus the true shift is from fixed expenditure to variable expenditure, not the other way around.
When this WOULD be correct
A question describing a company switching from a pay-per-use cloud model to a reserved instance with a flat monthly fee, where costs become predictable regardless of usage, would make 'from variable expenditure to fixed expenditure' 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.

Why this is correct
This is the classic financial model shift in cloud computing, where upfront hardware costs are replaced by ongoing operational costs.

✗From operational expenditure (OpEx) to capital expenditure (CapEx)Wrong answer — click to see why▾
Why this is wrong here
The question describes moving from purchasing servers (CapEx) to paying a monthly usage fee (OpEx), so the correct shift is from CapEx to OpEx, not the reverse.
★ When this WOULD be the correct answer
This option would be correct if a company moves from a pay-as-you-go cloud model (OpEx) to purchasing on-premises hardware (CapEx), e.g., migrating from cloud back to on-premises to reduce ongoing costs.
Why candidates choose this
Candidates may confuse the direction of the shift, thinking that cloud adoption always increases operational costs, or they may misremember which expenditure type corresponds to upfront vs. ongoing payments.
✗From direct expenditure to indirect expenditureWrong answer — click to see why▾
Why this is wrong here
The question specifically contrasts purchasing servers (CapEx) with paying a monthly usage fee (OpEx). 'Direct expenditure' and 'indirect expenditure' are accounting classifications unrelated to the capital vs. operational distinction in cloud economics.
★ When this WOULD be the correct answer
A question asks: 'A company pays for cloud services directly from its IT budget, while office rent is allocated across departments. This represents moving from which type of expenditure to which?' The answer would be from indirect expenditure to direct expenditure.
Why candidates choose this
Candidates may confuse 'direct' and 'indirect' with 'capital' and 'operational' because both pairs describe cost classifications, leading them to incorrectly apply the terms to the cloud migration scenario.
✗From variable expenditure to fixed expenditureWrong answer — click to see why▾
Why this is wrong here
In the scenario, moving from purchasing servers (CapEx) to a monthly usage fee (OpEx) is the opposite of moving from variable to fixed expenditure; cloud costs are typically variable based on usage, not fixed.
★ When this WOULD be the correct answer
A question describing a company switching from a pay-per-use cloud model to a reserved instance with a flat monthly fee, where costs become predictable regardless of usage, would make 'from variable expenditure to fixed expenditure' correct.
Why candidates choose this
Candidates may confuse OpEx with variable costs and CapEx with fixed costs, incorrectly assuming that cloud's pay-as-you-go model is fixed, when in fact it varies with consumption.

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.
