chapter 5 Flashcards
The planning of the implementation of a computer network infrastructure
Network Design
network design model are
flat and hierarchal
hierarchal structure layers
core, distributed and access
a _______ of high-end routers and switches that are optimized for availability and speed
core layer
a _______ of routers and switches that implement policies and segment traffic
distributed layer
a_______ that connects users via hubs, switches, and other devices
access layer
three task done by core layer
high data transfer rate, low latency and high reliability
Processes packets and regulates the transmission of packets based on its source and destination information to create network borders.
Packet filtering (firewalling)
The router or layer 3 switches can read packets and prioritize delivery, based on policies you set.
QOC
The distribution layer serves the aggregation point for the desktop layer switches
Access Layer Aggregation Point
benefits of hierarcal model
high performance, policy creation and scalable
It is used to provide a basic connectivity test between the requesting host and a destination host.
Ping
A command used in the operating system to view the entire path a packet takes to get from one device to another
Tracert/traceroute
Determine TCP/IP and network adapter information
Ipconfig/ifconfig
A command used by window operating system to troubleshoot DNS name resolution issues.
Nslookup
