Question 570 of 988
CLF-C02 Cloud Concepts Practice Question
A company's development team regularly creates temporary test environments. Each time, they log into the AWS Management Console, select the required Amazon EC2 instance types and storage, and launch the resources without needing to contact AWS support or their IT department. The team also terminates the resources when testing is complete. Which essential characteristic of cloud computing does this scenario best demonstrate?
⚠ Common exam trap
Test-takers frequently confuse 'broad network access' (access from anywhere via the internet) with the ability to self-provision, but the key differentiator is the lack of human intervention required, not the method of access.
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
✓
On-demand self-service
The scenario describes the development team provisioning and terminating EC2 instances and storage directly through the AWS Management Console without requiring human intervention from AWS support or their IT department. This is the precise definition of on-demand self-service, one of the five essential characteristics of cloud computing as defined by NIST SP 800-145, where a consumer can unilaterally provision computing capabilities as needed automatically.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Broad network access
Why it's wrong here
Broad network access means resources are available over the network and can be accessed by standard mechanisms (e.g., mobile phones, laptops). While the scenario involves using the AWS Management Console over the internet, the key differentiator is the lack of human interaction during provisioning, which is not captured by this characteristic.
When this WOULD be correct
A question that asks: 'A company's employees can access cloud resources from their office, home, and mobile devices using standard internet connections. Which cloud characteristic does this demonstrate?' would make broad network access correct.
- ✓
On-demand self-service
Why this is correct
On-demand self-service means the development team can provision and terminate computing resources—such as EC2 instances, databases, or test environments—automatically through the AWS Management Console, CLI, or APIs, without requiring a service desk ticket or any human approval from AWS. This characteristic, defined by NIST as the ability to unilaterally provision capabilities as needed, is exactly what the scenario demonstrates because the team independently spins up and tears down temporary test resources. The key differentiator is the absence of human interaction during the provisioning lifecycle, which is what distinguishes it from other characteristics like broad network access or measured service.
- ✗
Resource pooling
Why it's wrong here
Resource pooling describes the provider's ability to serve multiple customers from a shared pool of physical resources. The scenario does not emphasize multi-tenancy or sharing; it focuses on the user's ability to independently provision resources.
- ✗
Measured service
Why it's wrong here
Measured service means that cloud resource usage can be monitored, controlled, and reported for transparency and billing. Although AWS meters usage, the scenario specifically highlights the lack of human intervention during provisioning, not the metering aspect.
When this WOULD be correct
A company uses AWS to run a batch processing job and is billed based on the number of compute hours consumed. The question asks which cloud characteristic enables pay-per-use billing, making measured service 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 CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.

✗Broad network accessWrong answer — click to see why▾
Why this is wrong here
Broad network access refers to the ability to access cloud resources over the network via standard protocols, not the ability to provision resources without human interaction. The scenario emphasizes self-provisioning, not network accessibility.
★ When this WOULD be the correct answer
A question that asks: 'A company's employees can access cloud resources from their office, home, and mobile devices using standard internet connections. Which cloud characteristic does this demonstrate?' would make broad network access correct.
Why candidates choose this
Candidates may confuse 'broad network access' with the general idea of accessing AWS services via the internet, overlooking that the key action in the scenario is self-service provisioning, not network-based access.
✗Measured serviceWrong answer — click to see why▾
Why this is wrong here
Measured service refers to the ability to monitor, control, and report usage for billing purposes. The scenario emphasizes provisioning and terminating resources without human intervention, not usage tracking or metering.
★ When this WOULD be the correct answer
A company uses AWS to run a batch processing job and is billed based on the number of compute hours consumed. The question asks which cloud characteristic enables pay-per-use billing, making measured service the correct answer.
Why candidates choose this
Candidates may confuse 'measured service' with any automated action in the cloud, or think that logging into the console to launch resources implies usage measurement, but the focus is on self-provisioning, not metering.
