What are two benefits of following a structured hierarchical and modular design? (Choose two.)

Independent design per role means each layer - access, distribution, or core - can be engineered, sized, and optimized exclusively for its function without imposing constraints or complexity on adjacent layers, which is a foundational principle of modular network architecture.

Independent management per role enables administrators to apply targeted monitoring, configuration changes, and policies to a specific module without risking unintended impact on the rest of the network, reducing operational complexity and change risk.

Funding allocation by different organizational units is a financial governance concern with no direct relationship to the technical principles or benefits of hierarchical modular network design.

Assigning multiple roles to a single component directly contradicts the core principle of modularity, which requires clear role separation to reduce complexity and failure domains.

Redundancy is an outcome of specific design choices such as dual-homing or protocol-level failover mechanisms, not an inherent property or benefit of hierarchical modularity itself.
