An IT infrastructure architect is auditing a municipal transit agency's infrastructure. The agency maintains an internal compute environment used exclusively for its administrative operations on dedicated, self-managed hardware in its private data center. To enable real-time inter-agency dispatch and schedule coordination, the agency integrates this internal infrastructure with a separate shared platform that is co-funded, owned, and governed strictly by four regional public transit authorities for their mutual operational requirements. No commercial multi-tenant public cloud services are utilized. Which of the following cloud deployment model classifications best describes the agency's overall integrated environment?
- A hybrid cloud combining private and community cloud deployment modelsCevap
- BA community cloud deployment model exclusively
- CA hybrid cloud combining public infrastructure as a service (IaaS) and private cloud models
- DA private cloud deployment model operating under platform as a service (PaaS)
Cevap
The infrastructure is best classified as a hybrid cloud combining private and community cloud deployment models.
The correct answer accurately identifies the environment as a hybrid cloud combining private and community models. Under standardized CompTIA and NIST definitions, a hybrid cloud consists of two or more distinct cloud deployment models (public, private, or community) bound together by technology that enables data or app sharing. Here, the agency's single-tenant, internal infrastructure is a private cloud, while the multi-agency shared transit coordination platform is a community cloud.
