Which class of administration addresses an infrastructure with multiple sites or campuses?

The correct answer corresponds to Class 4 administration, which is specifically designed for managing an infrastructure that spans multiple sites or campuses. This classification recognizes the complexities and unique requirements that come with overseeing large-scale systems distributed across various locations. Class 4 administration involves coordinated strategies and policies to maintain consistency, performance, and compliance across all sites, ensuring that all components of the infrastructure can effectively communicate and operate together.

In the context of BICSI standards, Class 4 is essential for organizations that need to maintain a cohesive network presence across different physical locations. It encompasses not just the maintenance of the infrastructure, but also the alignment of resources, systems, and personnel to sustain seamless operations across diverse environments. This level of administration is crucial for organizations operating in sectors where multiple campuses are integral to their function, such as education, healthcare, and large enterprise operations.
