Which statement best describes the relationship between domain networks in a utility network?

The relationship between domain networks in a utility network is best described by the notion that they can share infrastructure where beneficial. This highlights the collaborative nature of utility networks, where different domain networks—such as water, electricity, and telecommunications—can utilize overlapping resources to enhance efficiency and service delivery. For example, shared conduits or poles can reduce costs, minimize physical disruption during construction, and simplify maintenance.

This interconnectivity encourages the optimization of resources and helps in integrated planning and management of utility services. In practice, this means that better resource allocation can lead to improved operational efficiency and customer service, thereby reinforcing the idea that usability can be enhanced when networks cooperate rather than function in isolation.

The other options suggest a level of separation or independence that does not reflect the practical realities of utility management. The focus on isolation or operating independently neglects the opportunities for collaboration that may lead to improved infrastructure management and service delivery. Aligning closely with administrative boundaries may offer structural advantages in governance, yet it doesn't capture the essence of functional interaction between various networks that can lead to greater efficiencies.
