GNS3 & Packet Tracer Quick Start Guides (vs VIRL & Physical) (Udemy.com)

It's not clear as expected but it's ok

This course was a great refresher for anyone who has studied or at least tried networking on a basic or advanced level. Students need to know the best option when trying to conquer or prepare for the CCNA or network + certification from the CompTIA exam. Kudos to the instructor for pointing out the pros and cons of each option.

ネットワーク機器の仮想ツールはどのようなものがあるか、またそれらと物理ハードウェアにどのようなメリット・デメリットがあるかをわかりやすく解説してくれます。実際のインストールと簡単な利用方法のイメージも動画でつかめるので、Ciscoをはじめとするネットワーク機器の学習をこれから始めようと考えている方に最適です。なお、IOSイメージの入手方法（年199ドル）についても説明があります。無償で入手する方法はありません。

I liked the possibility of choice of quality and speed. The program is pretty designed except that I’m experiencing trouble in downloading contents and I’m wondering if I have to attribute it to my internet providers even though I changed them often in order to fix the problem but the issue still the same.

Nice talking, great explanations. I would suggest David Bombal for network training especially for Cisco related and not only, got many of his courses and going to watch them all, and purchase rest of the courses that I don't have yet, this course is very informative about how to do networking practice and know about all the possible ways of doing it. 5/5

I enjoy David Bombal's videos on his youtube channel. This course showed me what you can see there, however, the biggest perk over going directly to his youtube channel is that through the course he is able to give you all the videos in the correct order, without ad's or interruptions. It was clean, to the point, and very informative. He covers both packet tracer, Virl, and GNS3 and a large emphasis on GNS3. This is what got me to dig further into using GNS3 because of his explanation and information with using it for creating labs and complex topologies.

Everything I wanted to know about GNS3 - was there. Now I can easily jump into other networking course and finally to start to gain my hands-on skill on cisco equipment. Well done David

Making such searches required patience and knowledges. I do respect that. In plus, I have learned things that I supposed to not being important but which I think can help me to better study.

David you've created a really useful course, it was really worth attending it . So I want to give an advice for those who want to learn GNS3 - start it from this course, you will get all the facts you need to begin working with GNS3.

crisp content.. clear in communicating the content.. would like to see a GNS3 Labs series for CCNA-CCNP-CCIE .. would be fun to learn from David .. with the way he walks through the course.
