This course is for Cisco's newest certification, the CCNA R/S 200-125, that became effective on August 21st, 2016.

This course is all you need to prepare & pass Cisco's new CCNA R/S 200-125 certification exam

Laz is notorious for his nonchalant and sometimes, unorthodox way of teaching. Not to mention his achievement in being instrumental in getting his students certified.

This is his latest course for the CCNA R/S and has everything one needs to prepare for the 200-125 certification exam.

The course was produced in a very effective manner where the student would feel as if they are in a classroom setting and the instructor is speaking directly to them.

In Laz's style of teaching, the course is very laid back to make the topics covered more digestible and easier for anyone to understand.

Whether you are a novice or just need a refresher, this course has everything you need to prepare & pass the 200-125 certification.

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. But 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 this site. This means you would have to replicate the 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 needed 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

Please keep in mind that Laz has his own book called "The Only IP Book You Will Ever Need!" that will further help those that need a more in-depth understanding of IPv4 & IPv6.

Also covered in this course is Wide Area Network Protocols like HDLC, PPP & Frame Relay, BGP, HSRP, MPLS among others

Students 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 among other things that are crucial in passing the new CCNA.

If you are tired of the same old methods of learning and want someone that is pretty much unconventional, but at the same time will provide you with an enjoyable learning experience in layman's terms...then please preview my courses and you will discover that I am your guy.

I am a Network Engineer with over 15+ years in the field and in the teaching industry. I hold the following certifications: CCNA, CCNA Security, CCNA Voice, Security+, Network+, A+, MCP, MCTS & MOS and I just passed the first of two test for the CCIE!

My teaching experience stems from teaching at institutions like Palm Beach Community College, New Horizons, Florida Career College (now Anthem College) and The Academy of South Florida, not to mention teaching at my own training facility in Miami, Florida.

Having been in all sides of the spectrum; as a student, a teacher/trainer, and in the field, I believe this uniquely qualifies me to understand the student, and what they have been exposed to as opposed to what they really want to accomplish. These two are sometimes extremely conflicting and frustrating. That is why I teach in the manner I do and can relate to the student's rejection of the Status Quo.

I have taught corporate employees at MetroPCS (now T-Mobil) and have also taught IT professionals of companies like The Florida Marlins, Hospital personnel & Attorney's firms amongst others to be able to acquire their CCNA certification and/or their Microsoft certifications; like the MOS (Microsoft Office Specialist). YES!...I am also an applications instructor and also teach Word, Excel, PowerPoint and Access.

I teach in an unconventional way that allows for students to understand the subject matter and can therefore, not only prepare them for a Cisco and/or Microsoft certification exam, but apply my methods in the real world. I strive to give the student a greater opportunity to compete in the current job markets. Do I go above and beyond what is needed for a certification?...YES, I do!...because it's not only about getting a certification, it's also about making sure the student is prepared for a job interview and/or maintaining their current job by enhancing their skills. This is where I step in and make sure that the student is prepared for whatever they need and make them an asset to their employer. Everyone has different requirements and I make sure, or at least I try, to provide information for most scenarios.

My classes and/or courses are very simple and that's how I like to teach. If things are kept simple, easy and explained in a way that the student can grasp quickly and retain the information...then I have achieved my goal!

For those that do not know me yet, you may not be used to my style of teaching, but you will soon get accustomed to it :)... I'm very laid back, I try to make learning fun and I teach in layman's terms...no physics jargon or mumbo jumbo in my teachings. My courses are very interactive and extremely dynamic!...you will not find my lectures monotone or boring, because falling asleep, for lack of excitement, is just NOT an option. Just take a look for yourself at my video previews, which I always provide on ALL my courses, so you can determine if I'm the right guy to help you get your industry specific certifications. ;)
