Full question →mediummultiple choiceObjective-mapped
A financial services company is required by regulation to keep all customer transaction data on-premises. However, they want to use AWS to run analytics workloads on this data using Amazon EMR and Amazon S3 for temporary storage of intermediate results. They need a solution that connects their on-premises network to AWS securely and allows them to extend their on-premises environment into the AWS Cloud. Which cloud computing deployment model does this scenario BEST describe?
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
Public cloud
A public cloud deployment means all infrastructure is hosted by a third-party provider (like AWS) and accessible over the internet. In this scenario, the company retains data on-premises, so it is not a purely public cloud model.
B
Distractor review
Private cloud
A private cloud deployment means infrastructure is used exclusively by a single organization, typically on-premises or in a dedicated hosted environment. Here, the company uses AWS services, so it is not entirely private cloud.
C
Best answer
Hybrid cloud
A hybrid cloud deployment combines on-premises infrastructure (private cloud) with public cloud services, connected securely. This matches the scenario where sensitive data stays on-premises while analytics run on AWS.
D
Distractor review
Community cloud
A community cloud is shared by several organizations with similar compliance or security concerns, often managed by a third party. This scenario involves only one company using a mix of on-premises and public cloud, not a shared community infrastructure.
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: Hybrid cloud — This scenario describes a hybrid cloud deployment model, which combines on-premises infrastructure (private cloud) with public cloud services (AWS). The company keeps sensitive data on-premises due to regulatory requirements but uses AWS for compute and temporary storage, connecting the two environments securely. This allows them to gain the benefits of cloud computing while maintaining compliance.
