Course Description

(NOTE: This course has been updated to version-3 (200-125) of CCNA RS requirements). 

Learn the technologies and concepts of networking in this complete course and earn your CISCO certification.

Have an awesome career in Data Communication, large scale service providers or simply make yourself more knowledgeable.

Basics of Networking

How switches function

What does routing mean

Design your own networks and implement Routing Protocols

Secure your CISCO devices

CISCO is the leading Networking equipment provider with a large product portfolio ranging from small Enterprises to large Data Centers. CCNA (R&S) certification is one of the fundamental certifications that will help you in realizing the computer networking concepts and its implementations in real world.

This course has been designed for beginner level IT Engineers. It will take you through the physical installation of the CISCO devices to the very epitome of configuring them and make amazing network topologies. This course will ensure that you understand the dreaded concepts of subnetting and spanning tree protocols. You will observe actual packets as they move through the wires and make those “dots connect”. While configuring the devices you will feel as if you are doing it yourself, its that close and personal. By following this course you will not only be able achieve your CCNA (R&S) certification but it will pave the foundation for your CCIE certification as well.

Check out my Youtube channel for free preview of Cloud Computing topic.

What are the requirements?

  • You should have access to real routers and switches but if thats not possible then GNS3 would suffice. Its free to download from GNS3 website. You can also use CISCO's "packettracer" as an alternate to practice this course labs.

What am I going to get from this course?

  • Understand and implement networking concepts and technologies. You will be able to configure, manage and troubleshoot CISCO routers and switches in the field.

Who is the target audience?

  • This course is meant for aspiring network engineers with little or nill knowledge of computer networking. And please if you are going for CCNA cert only, then this course is probably too long for you. Because my aim is to teach you and make you a better networking professional, CCNA will come as a by product.
