Final answer:
The question deals with identifying three principles of tiered network architecture. The correct principles are Segmentation, isolation, and integration, each fulfilling a unique role in network design and function.
Step-by-step explanation:
The question is asking to identify three foundational rules or principles of tiered network architecture. This concept is important in designing and managing complex networks, where different layers or tiers have distinct functions, alongside rules or principles that guide the interactions between these layers.
Among the provided options, Segmentation, isolation, integration are considered key principles in a tiered network architecture. Segmentation refers to dividing the network into manageable parts or segments to improve performance and manageability. Isolation pertains to keeping different segments or tiers separate to enhance security, by ensuring problems in one segment do not affect others. Finally, integration is the principle that ensures these separate segments work together cohesively as a single network.
Therefore, the correct answer to the question is Option A: Segmentation, isolation, integration.
