Certified Cloud Security Professional (CCSP) Practice Exam

Which cloud infrastructure model combines at least two distinct cloud infrastructures?

1. Host Intrusion Detection Systems (HIDS)

2. Hybrid cloud

3. Logical design

4. Multi-tenancy

The correct answer is: Hybrid cloud

The hybrid cloud model is defined by the combination of at least two distinct cloud infrastructures, which can include a mix of on-premises private cloud and public cloud services. This model allows organizations to leverage the benefits of both types of cloud environments, enabling greater flexibility, scalability, and efficiency in managing workloads. By using a hybrid cloud strategy, businesses can keep sensitive data in a private environment while utilizing the public cloud for less sensitive operations or for handling spikes in demand. This approach can optimize resource utilization, reduce costs, and improve performance, making it an increasingly popular choice for organizations looking to enhance their cloud computing capabilities. The other options mentioned do not fit the definition of combining distinct cloud infrastructures. For example, host intrusion detection systems focus on security monitoring rather than cloud infrastructure models, logical design pertains to the architectural arrangement of systems and applications, and multi-tenancy refers to a software architecture principle allowing multiple customers to share the same application resources while keeping their data isolated. Thus, those concepts do not express the idea of integrating different cloud infrastructures as effectively as the hybrid cloud model does.
