CLF-C02 Cloud Concepts Practice Question
A financial services company maintains a legacy on-premises database for sensitive customer data that must remain in a physically controlled environment due to regulatory requirements. The company runs its customer-facing web application on AWS to benefit from scalability and global reach. A dedicated encrypted VPN connection securely links the on-premises environment with the AWS cloud. Which cloud deployment model does this scenario BEST represent?
⚠ Common exam trap
The trap here is that candidates might confuse a hybrid cloud with a public cloud because the web application runs on AWS, but the key differentiator is the integration with on-premises infrastructure for regulatory compliance.

Correct answer & explanation
✓
Hybrid cloud
This scenario best represents a hybrid cloud because it combines on-premises infrastructure (the legacy database) with public cloud resources (AWS) connected via a dedicated encrypted VPN. The hybrid cloud model allows the company to keep sensitive data in a physically controlled environment while leveraging AWS's scalability for the customer-facing web application.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Public cloud
Why it's wrong here
Public cloud: A public cloud is exclusively composed of resources owned and operated by a cloud provider, like AWS, and delivered over the internet to multiple tenants. In this scenario, the company uses AWS as part of its architecture, but it also retains a significant portion of its workload on its own on-premises legacy systems. Because the overall deployment is not entirely on public cloud infrastructure—and because the on-premises component is an intentional, permanent part of the environment—this is not a purely public cloud model. The presence of a VPN connecting the on-premises site to AWS confirms that the company's footprint spans both environments, rather than being fully hosted in the public cloud.
When this WOULD be correct
A company runs all its applications and data entirely on AWS without any on-premises infrastructure, and there are no regulatory requirements for physical control. The question asks for the deployment model where resources are hosted on the provider's infrastructure and accessed over the internet.
- ✗
Private cloud
Why it's wrong here
Private cloud refers to cloud infrastructure used exclusively by a single organization, often hosted on-premises or by a third-party provider. The scenario uses a mix of on-premises and public cloud resources, not solely a private cloud.
When this WOULD be correct
A company runs all its IT infrastructure in a dedicated data center with no connection to any public cloud provider, and the environment is only accessible by that organization. This would be a private cloud deployment model.
- ✓
Hybrid cloud
Why this is correct
Hybrid cloud: The company integrates its legacy on-premises infrastructure with AWS public cloud resources through a VPN connection, actively managing workloads across both environments. This combination of a private on-premises data center and a public cloud provider, with orchestration and networking between the two, is the canonical definition of a hybrid cloud deployment model. The VPN connectivity ensures that data and workloads can move or be distributed seamlessly, which is a hallmark of hybrid architecture.
- ✗
Community cloud
Why it's wrong here
Community cloud: A community cloud is a shared, multi-tenant infrastructure operated for a group of organizations with common compliance, security, or regulatory concerns—such as a coalition of hospitals or financial institutions pooling resources on a shared platform. This scenario involves a single financial services company, not a consortium of several organizations with aligned interests. Even though the company has strict regulatory obligations, meeting those obligations on its own on-premises and AWS environment does not create a community cloud, because community cloud is fundamentally a shared infrastructure model, not an isolated single-tenant deployment.
When this WOULD be correct
A question where multiple organizations with the same regulatory requirements (e.g., healthcare providers sharing a cloud for HIPAA compliance) jointly use a cloud infrastructure managed by a third party or one of them, and the cloud is not open to the general public.
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.

✗Public cloudWrong answer — click to see why▾
Why this is wrong here
The scenario involves a hybrid setup with both on-premises and AWS resources connected via VPN, which is not purely public cloud.
★ When this WOULD be the correct answer
A company runs all its applications and data entirely on AWS without any on-premises infrastructure, and there are no regulatory requirements for physical control. The question asks for the deployment model where resources are hosted on the provider's infrastructure and accessed over the internet.
Why candidates choose this
Candidates may think that because the customer-facing web application runs on AWS (a public cloud provider), the entire deployment is public cloud, overlooking the on-premises component.
✗Private cloudWrong answer — click to see why▾
Why this is wrong here
The scenario describes a combination of on-premises and AWS cloud resources connected via VPN, which is the definition of a hybrid cloud. A private cloud would require the entire infrastructure to be dedicated to a single organization and not involve public cloud services like AWS.
★ When this WOULD be the correct answer
A company runs all its IT infrastructure in a dedicated data center with no connection to any public cloud provider, and the environment is only accessible by that organization. This would be a private cloud deployment model.
Why candidates choose this
Candidates may confuse the use of a dedicated VPN and sensitive data with a private cloud, mistakenly thinking that any secure, isolated environment is private, without recognizing that the presence of AWS public cloud services makes it hybrid.
✗Community cloudWrong answer — click to see why▾
Why this is wrong here
A community cloud is shared by several organizations with common concerns (e.g., regulatory compliance), but this scenario involves a single company using both on-premises and AWS resources, which is a hybrid cloud.
★ When this WOULD be the correct answer
A question where multiple organizations with the same regulatory requirements (e.g., healthcare providers sharing a cloud for HIPAA compliance) jointly use a cloud infrastructure managed by a third party or one of them, and the cloud is not open to the general public.
Why candidates choose this
Candidates may confuse 'community cloud' with any cloud that has strict regulatory controls, not realizing that community cloud specifically implies multi-tenant sharing among a group with common interests.

Same concept, more angles
4 more ways this is tested on CLF-C02
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A financial services company keeps sensitive customer data in an on-premises data center. Regulatory requirements prohibit this data from being stored in the cloud. However, the company needs to run compute-intensive analytics jobs that periodically require more processing power than its on-premises servers can provide. The company wants to use AWS for these burst capacity needs while keeping the sensitive data on premises. Which cloud deployment model best describes this approach?
easy- A.Public cloud
- B.Private cloud
- ✓ C.Hybrid cloud
- D.Community cloud
Why C: The hybrid cloud model is correct because it combines on-premises infrastructure (private cloud) with public cloud resources (AWS) while keeping sensitive data on-premises. The company uses AWS for burst compute capacity via services like AWS Batch or EC2 Auto Scaling, but the data never leaves the on-premises data center, satisfying regulatory requirements.
Variation 2. A company has a strict data residency policy that requires all customer data to remain stored on-premises at all times. However, the company experiences unpredictable spikes in compute demand and wants to use an AWS cloud environment to handle this additional workload during peak periods. The company needs a solution that allows them to seamlessly run applications across their on-premises infrastructure and AWS, using consistent management tools and APIs. The company also needs a dedicated, private network connection between the two environments for low latency and security. Which cloud deployment model best describes this architecture?
easy- A.Public cloud
- B.Private cloud
- ✓ C.Hybrid cloud
- D.Community cloud
Why C: The architecture described combines on-premises infrastructure with AWS cloud resources, connected via a dedicated private network (likely AWS Direct Connect or VPN), while using consistent management tools and APIs. This is the defining characteristic of a hybrid cloud model, which enables workload portability and unified operations across both environments.
Variation 3. A financial services company must keep customer financial records on-premises to comply with data residency regulations. The company wants to use AWS services such as Amazon SageMaker and Amazon Athena to run analytics on anonymized subsets of the data. The company establishes a dedicated AWS Direct Connect connection between its on-premises data center and its VPC, and uses AWS Storage Gateway to cache frequently accessed data locally while storing all data in Amazon S3. Which cloud deployment model does this architecture represent?
medium- A.Public cloud
- B.Private cloud
- ✓ C.Hybrid cloud
- D.Community cloud
Why C: This architecture combines on-premises infrastructure (customer data center with AWS Storage Gateway caching) with AWS cloud services (SageMaker, Athena, S3) connected via AWS Direct Connect, which is the defining characteristic of a hybrid cloud deployment. A hybrid cloud model integrates private on-premises resources with public cloud services, allowing data to remain on-premises for compliance while leveraging cloud analytics.
Variation 4. 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?
medium- A.Public cloud
- B.Private cloud
- ✓ C.Hybrid cloud
- D.Community cloud
Why C: The scenario describes a hybrid cloud deployment model, where the company maintains on-premises infrastructure for regulatory compliance (keeping customer transaction data on-premises) while leveraging AWS public cloud services (Amazon EMR and Amazon S3) for analytics workloads. The requirement to connect the on-premises network to AWS securely and extend the on-premises environment into the AWS Cloud is a defining characteristic of hybrid cloud, often implemented using AWS Direct Connect or VPN connections to create a unified network.
