Certified Cloud Security Professional (CCSP) Practice Exam

Which concept refers to data center networks being logically divided into smaller, isolated networks?

1. Hybrid cloud

2. Multi-tenancy

3. Logical design

4. Converged networking model

The correct answer is: Multi-tenancy

The concept that refers to data center networks being logically divided into smaller, isolated networks is multi-tenancy. In a multi-tenant architecture, multiple customers or clients share the same physical infrastructure while maintaining separation and security of their individual data. This logical isolation allows for resource efficiency, scalability, and cost-effectiveness, as various tenants can use the same resources without interfering with one another. This is particularly significant in cloud environments, where providers serve multiple customers using shared resources. Multi-tenancy supports the idea of creating distinct environments for each user, which is essential for maintaining security and meeting compliance requirements. Other options, while related to networking and cloud concepts, do not accurately capture the essence of the definition provided. Hybrid cloud refers to a combination of on-premises infrastructure with cloud resources, while logical design pertains to the overall architecture planning and structure without specifically denoting isolation of networks. The converged networking model integrates storage, computing, and networking into a single system, but it does not focus on segmentation or isolation.
