- A
Public cloud
Why wrong: Public cloud is a model where all resources are hosted off-premises and shared with other customers. This would require the sensitive data to be stored in the cloud, violating regulatory requirements.
- B
Private cloud
Why wrong: A private cloud is dedicated to a single organization but is typically hosted in a cloud provider's data center, not on-premises. It does not allow for the burst capacity from a public provider like AWS while keeping data on-premises.
- C
Hybrid cloud
Hybrid cloud connects on-premises infrastructure with public cloud services. This enables the company to keep sensitive data on-premises for compliance while leveraging AWS for burst compute capacity, matching the described requirements.
- D
Community cloud
Why wrong: Community cloud is a model where infrastructure is shared by several organizations from a specific community with common compliance or security concerns. It does not involve combining on-premises and public cloud resources.
Quick Answer
The correct answer is the hybrid cloud deployment model. This model is the right choice because it combines on-premises infrastructure—effectively a private cloud for sensitive data—with public cloud resources like AWS, allowing the company to meet strict regulatory requirements while scaling compute capacity on demand. In this scenario, the sensitive customer data remains securely on premises, and AWS is used only for burst processing power through services like EC2 Auto Scaling or AWS Batch, ensuring compliance without sacrificing performance. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of how hybrid cloud uniquely addresses data residency and elasticity needs, often appearing as a scenario where a private cloud alone lacks scalability or a public cloud alone violates compliance. A common trap is choosing public cloud because it offers burst capacity, but the key is that data never leaves the on-premises environment. Remember the memory tip: hybrid cloud keeps the crown jewels on-site while borrowing the cloud’s muscle.
CLF-C02 Cloud Concepts Practice Question
This CLF-C02 practice question tests your understanding of cloud concepts. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'hybrid cloud' with 'public cloud' because they see AWS usage, but the key distinction is that sensitive data stays on-premises, making it a hybrid model, not a pure public cloud deployment.
Detailed technical explanation
How to think about this question
In a hybrid cloud architecture, the on-premises environment can connect to AWS via AWS Direct Connect or VPN, enabling burst workloads to access compute resources like EC2 Spot Instances or AWS Lambda without transferring sensitive data. The data remains on-premises, and the compute jobs can read/write data over encrypted connections (e.g., TLS 1.2) or use services like AWS Storage Gateway to cache data locally. This model is common in regulated industries where data residency is mandated by standards like PCI DSS or GDPR.
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.
TExam Day Tips
- 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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.

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 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: Option C is correct because 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 2. 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 3. 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: Option C is correct because 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.
Variation 4. 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?
medium- A.Public cloud
- B.Private cloud
- ✓ C.Hybrid cloud
- D.Community cloud
Why C: 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.
