Lesson Summary

■

A network infrastructure is a set of components that provide connectivity, security,

routing, management, access, and other integral features on a network. A net-

work’s physical infrastructure is the physical design of the network, consisting of

hardware components such as cabling, routers, switches, hubs, servers, and work-

stations.

■

A network’s logical infrastructure comprises the many software elements that con-

nect, manage, and secure hosts on the network.

■

When planning a network infrastructure, you must determine the requirements of

the network’s users, administrators, and owners, and then design a configuration

of selected physical and logical components that satisfies those requirements.

■

When implementing a network infrastructure, it is important to understand the

organizational aspects of the product deployment, such as the allocation of IP

addresses and designing a DNS namespace.

■

The maintenance of a network infrastructure includes tasks such as deploying

software updates, monitoring network performance and processes, and trouble-

shooting problems.
