2,. Why would a company want network engineers to adhere to structured
engineering principles when designing networks?
he resiliency of a network depends on being able to modify portions of the network, add
services, or increase network capacity without adding new hardware devices'
he network is not e%pected to remain available under abnormal conditions such as
e%treme traffic loads or denial-of-service events'
he network can !e easily designed !ecause of the separation of the +arious
functions that e$ist on a network into modules.*
A hierarchical network model is a useful high-level tool for designing a reliable network
infrastructure, although it increases the comple%ity of network design'
