“Cisco CCNA (200-125) The Complete Course”: The requirements

The student needs to have basic networking knowledge and preferably network simulator knowledge such as Packet Tracer or GNS3. That’s because, during the course, the instructor produces scenarios built around network simulators. So in order to focus on the CCNA material, it is better to get some hands on a network simulator/emulator.

“Cisco CCNA (200-125) The Complete Course”: The Pro’s

  • The way it is taught: this course is not just a bunch of slides where you have to stare at them a couple of minutes. Instead, the instructor is giving lectures in front of a giant touch-screen, which produces a virtual teacher-to-student relationship with cutting-edge technology. I love this better than lectures where teachers are only recording video on their screens.Cisco-CCNA-R/S-(200-125)-The-Complete-Course-2
  • The instructor seems to know his stuff very well
  • The occasional jokes made by the instructor. No boring creepy speaker like in regular IT training courses. The instructor keeps you interested and engaged all the time. He emphasizes some points by using his body language and charisma, which you can not have in a course with an instructor hiding behind the slides
  • Real-life application of the content
  • Superb explanation of IPv4 subnetting
  • He gives some exam question hintsCisco-CCNA-R/S-(200-125)-The-Complete-Course-1
  • he makes the topics easy to understand
  • The ease with wich you can map the content to a home lab setup
  • The lectures’ scope is beyond the CCNA exam. Lazaro gives real-life application of the content he is teaching. And not only he explains the difference of what’s needed in a real network, but he also draws attention on what’s needed on the test
  • Use of lots of examples to further clarify networking concepts, and many labs. By the way, Lazaro has a dropbox link where he put all the course labs
  • the cool T-shirts he is wearing during the course. It makes learning Cisco networking fun.

“Cisco CCNA (200-125) The Complete Course”: The Con’s

  • The course is probably not for über beginners in the networking field. And Lazaro clearly mention that in the few first lectures. So he seems to rush on some parts of the course while spending too much time on other parts. That’s why for the underlying details, you may need to make a bit of research on your own.
  • Lazaro did not mention where he buys his T-Shirts :)

“Cisco CCNA (200-125) The Complete Course”: Verdict

Some students are overwhelmed by the amount of textbooks they need to read. This CCNA video course breaks the syllabus into easy-to-follow lectures. It seems to cover everything in the exam in detail.

If you want a budget self-paced course that will teach you CCNA concepts from soup to nuts, then go with Laz and you’ll get an extra bonus of humour. Lazaro is the kind of instructors that should teach not only Cisco CCNA courses, but any Cisco course. This course could help you pass the CCNA exam with very good marks.
