Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A small business wants to migrate its IT infrastructure to Azure. The owner wants the ability to provision new virtual machines, storage accounts, and databases entirely through a web-based portal, without needing to submit a formal request or wait for an administrator to manually allocate resources. The owner expects resources to be available immediately after configuration. Which characteristic of cloud computing does this scenario best illustrate?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
On-demand self-service
Correct. On-demand self-service means a consumer can provision computing capabilities (e.g., virtual machines, storage) as needed automatically without requiring human interaction with each service provider. The scenario where the owner uses the Azure portal to create resources without contacting Microsoft directly perfectly matches this characteristic.
B
Distractor review
Broad network access
Incorrect. Broad network access means resources are available over the network and accessed through standard mechanisms (e.g., web browsers, REST APIs). While the Azure portal is accessed via a network, the key point in the scenario is the lack of human interaction during provisioning, not the method of access.
C
Distractor review
Resource pooling
Incorrect. Resource pooling means the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with physical and virtual resources dynamically assigned and reassigned. The scenario does not address how resources are shared among customers; it focuses on the immediate, self-service provisioning capability.
D
Distractor review
Rapid elasticity
Incorrect. Rapid elasticity refers to the ability to quickly scale resources up or out in response to demand, and then scale back down. The scenario describes provisioning a new resource (creating a VM), not dynamically scaling existing resources based on load. The emphasis is on the self-service aspect, not elasticity.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this AZ-900 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: On-demand self-service — The scenario describes a user creating cloud resources directly through a self-service interface (the Azure portal) without requiring human intervention from the cloud provider. This is the NIST-defined characteristic of on-demand self-service. Broad network access refers to access over the network via standard protocols. Resource pooling means the provider's computing resources are pooled to serve multiple customers. Rapid elasticity allows resources to scale out or in quickly, but the scenario focuses on the user's ability to provision without human assistance, not on scaling speed.
