  • Understanding the concepts as provided in this course is an essential part of any network in order to communicate and transmit information. Mastering this knowledge will make the student or IT Professional a much more valuable asset in any Network or IT environment.
  • This course will change over to the new CCNA 200-125.
  • The student will have both the lectures from the old CCNA 200-120 (which covers about 70% of the new test), but it also covers all the new topics and lectures for Cisco's new exam, the CNA 200-125
  • Basic understanding of Networking
  • Students will need to obtain, either the Cisco Packet Tracer or similar simulators (i.e.: GNS3, BOSON, ETC). These are not part of the course and it is not provided.
  • A CCNA R/S Study Guide book would be helpful
  • Desire to pass the CCNA R/S certification exam

This course is over 45+ hours long and will cover all the needed subjects to be successful in passing the CCNA 200-120 exam and the new CCNA 200-125.

Students will acquire the knowledge and practice labs in this course to make it transferable to real world use, as a Cisco and/or IT Professional.

DISCLAIMER:   Please note that the simulators/emulators used in this course are NOT part of the course. It is the students responsibility to have these to practice with.
The Cisco Packet Tracer & VIRAL (Virtual Internet Routing Lab) are Cisco proprietary software and can only be obtained through Cisco.
However, students have more options that those. They can create their own lab with real equipment, get BOSON or GNS3.
It is up to each student to obtain the simulator/emulator of their choice to study along with this course.
Please also NOTE:  .pkt files are not up-loadable to UDEMY's site.
This means you would have to replicate my labs here in order to practice and follow along.

This course will give students an in-depth understanding of networking, using routers and switches and their various configurations and connections. Students will learn how to configure; default, static and dynamic routing. Students will comprehend how to manipulate each of the routing protocols attributes to meet the requirements of the network.

This course will also prepare the student in Layer 2 technology and its various configurations, such as; VLAN’s, VTP, STP, PortFast, EtherChannel, Port-Security, Inter-VLAN communication & Trunking; plus the newest requirements for the CCNA (200-125) certification exam as well.

Students will also acquire the knowledge needed to secure their routers through the use of Access-list, configuring the different types of NAT & will be able to manage the router’s components.

Students will also be able to thoroughly grasp the concepts of both Internet Protocols; IPv4 & IPv6.

Wide Area Network Protocols will also be covered; HDLC, PPP & Frame Relay. The student will also learn how to create redundancy in their networks through the use of Redundancy Protocols such as HSRP which is just as important. Also, within the WAN, the student will also learn how to create VPN’s and GRE Tunnels.

This is a full comprehensive course that will take you from A-Z in your quest for the CCNA (200-120) & now includes Cisco's NEW CCNA (200-125).

About "the book":

Throughout the course, you will hear me mention "your book", "a book" or "the book"...and if you're wondering why I don't mention a's because this was done on purpose.

I don't want anyone to purchase a book if you already have one...all CCNA study guides cover the same thing in different manners. So if you already have a CCNA book, you can use it with this course.

However, for those that wonder which book I use in this they are:

  1. Sybex book by Todd Lammle  - CCNA 200-120 
  2. Amazon book by Lazaro Diaz - The Only IP Book You Will Ever Need!

Hope you enjoy the course!
