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.
