CBT NUGGETS CISCO CCNA 640.822.ICND1

Lets get started step By step

Video
1 - Welcome to the CBTNuggets CCENT video series! - This opening video
sets the expectations for the entire CCENT series as well as reviewing
the Cisco certification track. Because Jeremy gives many certification
exam tips and advice, it is recommended that you view this video once
more after finishing the series.

Video 2 - Foundations: What is
a Network? - This video answers the question of why. Why do we need a
network? What does the network accomplish for us? Without understanding
this foundation, the rest of the Cisco certification track will not
make much sense.

Video 3 - Foundations: Living in the OSI World
- If someone told you, "My car is broken," but was unable to expand on
what exactly was broken, you wouldn't know where to begin looking for a
solution. In the same sense, networks are an extremely complex system
of communicating. The OSI Model holds the key to understanding the
layers of network functionality. This video walks through both a
logical and practical presentation of the OSI Model.

Video 4 -
Basic TCP/IP: Addressing Fundamentals - We live in a TCP/IP world.
Having a thorough understanding of this protocol is critical to your
success in any network environment. This video breaks down the basics
of TCP/IP and discusses concepts such as IP address format, public and
private addressing, and address classes. Jeremy also walks you through
the reasons why having TWO addresses is the key to successful network
communication.

Video 5 - Basic TCP/IP: TCP and UDP Communication
- Every network-aware application has a choice to make when it
communicates across the network: TCP or UDP. This decision determines
how reliable the data transfer will be. This video walks through the
discussion of TCP and UDP, focusing specifically on TCP windowing,
sequence numbers, and acknowledgements.

Video 6 - TCP/IP:
Understanding Port Numbers - Imagine that you wanted to see your friend
Dave who lived in a house with 100 other people. As soon as you reached
the house, you would open the door and yell, "I'M LOOKING FOR DAVE!!!"
Port numbers do exactly the same thing for network communication
between devices, allowing you to dictate what service you are trying to
reach. This video gives practical examples of using TCP and UDP port
numbers when communicating.

Video 7 - Basic TCP/IP: The Tale of
Two Packets - To wrap up the section on Basic TCP/IP communication,
Jeremy walks you through the "Tale of Two Packets." This gives a big
picture perspective on local network communication (the Bob packet) and
remote network communication (the Sally packet).

Video 8 - LANs:
Welcome to Ethernet - Ethernet defines the standard for LAN
communication around the world. Because of this, it is critical to
understand the fundamentals of how this "fabric of networks" operates.
This video walks through the origins of the Ethernet standard, CSMA/CD
(the rules of communication), and the architecture of a MAC address.

Video
9 - LANs: Understanding the Physical Connections - If you've never
experienced calloused fingers from crimping Ethernet cables, this video
is for you. In it, Jeremy walks through the two primary physical
standards of Ethernet: UTP and Fiber Optics, straight-through vs.
crossover cables, and an end-to-end picture of cabling in a corporate
environment.

Video 10 - LANs: Understanding LAN Switches -
Ethernet's use of CSMA/CD allowed it to obtain much faster speeds than
its competitor (token ring); however, it also led to many problems with
collisions in larger networks. This video walks through the solution to
those problems and lays the foundation understanding of how the network
switch fits into our network environments.

Video 11 - LANs:
Working with the Cisco Switch IOS - Before you can jump right into
setting up Cisco switches, you must understand how to work with Cisco's
operating system: the IOS. This video walks you through the general
navigation and help features of the IOS.

Video 12 - LANs:
Initial Setup of a Cisco Switch - With the IOS foundations in place,
this video jumps straight into the initial configuration of a Cisco
switch. In this video you will see the meaning of the physical LEDs on
a switch, the initial boot process and configuration dialog, and the
configuration of a VLAN interface.

Video 13 - LANs: Configuring
Switch Security, Part 1- Network security has become such a major topic
that Cisco has moved much of what used to be considered a CCSP
(security professional) topic into the CCENT and CCNA certifications.
This video discusses the initial security of your switch, primarily
focusing on configuring passwords, logon banners, and SSH.

Video
14 - LANs: Configuring Switch Security, Part 2 - The network security
topics continue. In this video, Jeremy walks you through enabling port
security for your network, which gives you complete control of the
number and type of devices that attach to your network.

Video 15
- LANs: Optimizing and Troubleshooting Switches - It's time to wrap up
the world of LAN switching with optimization and troubleshooting. In
this video, Jeremy walks through common problems you may encounter when
working in a LAN environment. He also interjects a "bonus section"
dealing with improving your efficiency on Cisco devices.

Video
16 - Wireless: Understanding Wireless Networking - Wireless networking
technology has changed the LAN landscape very quickly. As one of the
newest technologies added to the CCENT/CCNA certifications, wireless is
almost guaranteed to pop up in organizations of any size. This video
discusses the foundations of wireless networks including radio
frequency, wireless channels and standards, and the best way to design
wireless for your organization.

Video 17 - Wireless: Wireless
Security and Implementation - Understanding the foundations of wireless
is never enough! Security vulnerabilities have proven more than once
that wireless can be devastating to an organization. This video walks
through the steps to take to successfully implement and secure a
wireless network.

Video 18 - Advanced TCP/IP: Working with
Binary - This video begins the move to the world of advanced TCP/IP
addressing. More specifically, you will learn the skill of IP
subnetting. One of the most foundational skills in subnetting is
converting from decimal to binary and back. This video carefully
explains this skill and provides many examples to practice.

Video
19 - Advanced TCP/IP: IP Subnetting, Part 1 - The first style of
subnetting you'll need to learn is the ability to separate IP addresses
into subnets based on the number of networks an organization needs.
This video walks through the initial style.

Video 20 - Advanced
TCP/IP: IP Subnetting, Part 2 - The second style of subnetting you'll
need to learn is the ability to separate IP addresses into subnets
based on the number of hosts an organization needs in each network.
This video explains this style.

Video 21 - Advanced TCP/IP: IP
Subnetting, Part 3 - The final style of subnetting you'll need to learn
is the ability to reverse engineer subnets based on the IP address and
subnet mask that has been given. This video discusses this final style.
