AZ-900 Describe cloud concepts Practice Question
A company historically purchased physical servers and networking equipment for its data center, paying the full cost upfront before using the hardware. The company is now migrating its workloads to Azure and will only pay for the compute and storage resources it consumes each month, with no long-term commitments or upfront hardware purchases. This financial model change best represents which cloud computing benefit?
⚠ Common exam trap
It's easy for candidates to confuse elasticity (the ability to scale) with consumption-based pricing (the financial model), but the question specifically asks about the change in financial model from upfront hardware costs to paying only for consumed resources.
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
✓
Consumption-based pricing
The scenario describes a shift from upfront capital expenditure (CapEx) for physical hardware to a model where the company pays only for the resources it consumes each month, without long-term commitments. This directly aligns with consumption-based pricing, a core Azure benefit where costs are incurred based on actual usage of compute, storage, and other services, eliminating the need for upfront hardware purchases.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
High availability
Why it's wrong here
High availability ensures that applications and data remain accessible despite component failures. While Azure provides availability guarantees, the question focuses on the shift from upfront hardware purchases to monthly consumption-based payments, not on uptime or fault tolerance.
When this WOULD be correct
A question asks: 'A company deploys its application across multiple Azure availability zones to ensure it remains running even if one data center fails. Which cloud benefit does this represent?' In that scenario, high availability would be the correct answer.
- ✗
Elasticity
Why it's wrong here
Elasticity is the ability to automatically scale resources up or down based on demand. Although Azure enables elasticity, the scenario specifically describes a change in financial model (upfront cost vs. monthly consumption), not the ability to adjust resource quantity dynamically.
When this WOULD be correct
A question describing a workload with variable demand that automatically scales virtual machines in response to traffic spikes, asking which cloud benefit enables this dynamic resource adjustment.
- ✓
Consumption-based pricing
Why this is correct
Consumption-based pricing, also known as pay-as-you-go, means customers pay only for the resources they actually use, with no upfront costs or long-term commitments. This directly matches the scenario where the company moves from purchasing hardware upfront to paying monthly for Azure resources consumed.
- ✗
Disaster recovery
Why it's wrong here
Disaster recovery is a cloud benefit that focuses on maintaining business continuity by replicating infrastructure, applications, and data to a separate geographical region or site, enabling failover and restoration after a catastrophic failure. This answer is incorrect because the scenario describes only a change in the financial purchasing model—from upfront capital expenditure on physical servers and networking to monthly operational expenditure for Azure resources—and does not mention any backup, replication, failover, or recovery requirements. Disaster recovery is conceptually orthogonal to how customers pay for cloud services, whereas the question clearly points to a pay-as-you-go or consumption-based billing arrangement.
When this WOULD be correct
A company wants to ensure its critical applications can automatically fail over to a secondary Azure region during a regional outage. The benefit of Azure's built-in disaster recovery capabilities would be the correct answer.
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.
✓Consumption-based pricingCorrect answer▾
Why this is correct
Consumption-based pricing, also known as pay-as-you-go, means customers pay only for the resources they actually use, with no upfront costs or long-term commitments. This directly matches the scenario where the company moves from purchasing hardware upfront to paying monthly for Azure resources consumed.
✗High availabilityWrong answer — click to see why▾
Why this is wrong here
The question focuses on the shift from upfront capital expenditure to paying only for consumed resources, which directly describes consumption-based pricing, not high availability. High availability refers to ensuring services remain operational despite failures, not the financial model.
★ When this WOULD be the correct answer
A question asks: 'A company deploys its application across multiple Azure availability zones to ensure it remains running even if one data center fails. Which cloud benefit does this represent?' In that scenario, high availability would be the correct answer.
Why candidates choose this
Candidates may confuse the general reliability benefits of the cloud (like high availability) with the specific financial model described, or they may think that paying only for what you use inherently improves availability.
✗ElasticityWrong answer — click to see why▾
Why this is wrong here
Elasticity refers to the ability to automatically scale resources up or down based on demand, not the shift from upfront capital expenditure to paying only for consumed resources.
★ When this WOULD be the correct answer
A question describing a workload with variable demand that automatically scales virtual machines in response to traffic spikes, asking which cloud benefit enables this dynamic resource adjustment.
Why candidates choose this
Candidates may confuse the pay-as-you-go model with elasticity because both involve flexibility in cloud usage, but elasticity specifically addresses scaling, not pricing structure.
✗Disaster recoveryWrong answer — click to see why▾
Why this is wrong here
Disaster recovery refers to the ability to recover from failures and maintain business continuity, not to the financial model of paying only for consumed resources without upfront costs.
★ When this WOULD be the correct answer
A company wants to ensure its critical applications can automatically fail over to a secondary Azure region during a regional outage. The benefit of Azure's built-in disaster recovery capabilities would be the correct answer.
Why candidates choose this
Candidates may confuse disaster recovery with the general benefit of avoiding large capital expenditures, as both involve cost savings, but disaster recovery is specifically about resilience, not pricing models.

What is Cloud Computing?
Key term
Cloud computing
Cloud computing is the on-demand delivery of IT resources over the internet, allowing users to access computing power, storage, and applications without owning physical hardware.
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.
