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'

2. 5efer to the e$hi!it. Which Cisco #nterprise "rchitecture module is shown?
