Full question →mediummultiple choiceObjective-mapped
A development team needs to spin up a new Amazon RDS database instance for a proof-of-concept application. The team can log into the AWS Management Console, select the database engine, configure settings, and launch the instance within minutes, without needing to submit a ticket or wait for IT operations to provision hardware. Which essential characteristic of cloud computing does this scenario BEST demonstrate?
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
Distractor review
Resource pooling
Resource pooling describes how the cloud provider's physical and virtual resources are pooled to serve multiple customers using a multi-tenant model. While AWS does pool resources, the scenario highlights the user's ability to provision a resource without human intervention, which is not about the pooling itself.
B
Distractor review
Measured service
Measured service refers to the cloud provider's ability to monitor, control, and report resource usage (e.g., metering for billing). The scenario does not focus on usage tracking or billing, but on the immediate, self-service provisioning of a database instance.
C
Best answer
On-demand self-service
On-demand self-service is a key characteristic of cloud computing that enables users to provision computing resources automatically as needed, without requiring human interaction with the service provider. The team's ability to launch an RDS instance directly via the console, without waiting for IT staff, is a direct example of this characteristic.
D
Distractor review
Rapid elasticity
Rapid elasticity is the ability to quickly scale resources up or down in response to demand. While AWS RDS can be scaled, the scenario describes the initial provisioning of a single instance, not a scaling action in response to changing demand.
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.

Question 1
A developer needs to launch a test server for a new application prototype. The developer logs into the AWS Management Console, selects an Amazon EC2 instance type, configures the security group, and starts the instance. The instance is running within two minutes, and the developer did not need to submit a formal request to the company's IT procurement team or wait for approval from a cloud administrator. Which essential characteristic of cloud computing does this scenario best demonstrate?
Question 2
A solutions architect is planning a new web application on AWS. The workload will include 3 Amazon EC2 instances (t3.medium) running 24/7, an Application Load Balancer, and an Amazon RDS for MySQL db.t3.small database. The architect needs to estimate the monthly cost for the first year, considering different purchasing options (On-Demand, 1-year All Upfront Reserved Instance, and Compute Savings Plan). Which AWS tool should the architect use to create this estimate?
Question 3
A company's development team frequently needs temporary test environments. A developer can log into the AWS Management Console, select an Amazon EC2 instance type, configure storage, and launch the instance within minutes without any interaction with the IT infrastructure team. This capability is an example of which essential characteristic of cloud computing?
Question 4
A company's finance team needs to analyze AWS spending in detail. They require a report that includes hourly cost data for each AWS service, each individual resource (e.g., a specific EC2 instance), and any cost allocation tags applied. The team plans to export this data to an Amazon S3 bucket and then import it into a custom business intelligence (BI) analytics dashboard. Which AWS tool should the finance team use to generate this level of detailed cost data?
Question 5
A company uses AWS for its development environment. The finance team wants to set a monthly budget of $10,000. They want to receive an email notification when the actual costs reach 80% of the budget ($8,000) and again when costs exceed the budget. The team needs a managed AWS service that can automatically send these alerts without requiring custom code or third-party tools. Which AWS service should the team use?
Question 6
A company uses AWS Organizations to manage multiple accounts. The security team needs to enforce a policy that restricts SSH access (port 22) from the internet (0.0.0.0/0) in all VPCs across all accounts. The team wants to centrally define the allowed rules and automatically apply them to newly created VPCs and security groups, while also automatically remediating any existing non-compliant security groups. Which AWS service should the team use?
FAQ
Questions learners often ask
What does this CLF-C02 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 — This scenario demonstrates the on-demand self-service characteristic of cloud computing. On-demand self-service means that users can provision and configure resources automatically, without requiring human interaction with the service provider. In this case, the development team directly provisions the RDS instance via the console, without waiting for IT operations or any manual approval process. Resource pooling refers to the provider's multi-tenant model where resources are shared across customers. Measured service involves metering and monitoring resource usage for billing and optimization. Rapid elasticity is the ability to scale resources up or down quickly, which is not the primary focus of this initial provisioning action.
