Anthony, I enjoyed the router session much more than the first one. Doing the questions as a in class also allows for more discussion & asking questions or clarifying! Once the session is over, its hard to take time on the next one to go back & redo topics.
Thanks for the awesome session. I missed it last night, but reviewed it this morning. Your contemporaries over at CBT Nuggets have produced a good analogy of the OSI model by using the example of two kingdoms communicating back and forth. I just wondered if you know of a great visual representation of the OSI model . . . .something that takes a student through a visual representation of how all of the layers and protocols and devices are all laid out?
You scored 8 out of 8.
Thanks to many years of teaching OSI Model in Cisco courses. Excited to learn the latest in 007 in the TTT course. I have shown many of your videos in my Cisco classes. Thanks for doing this Anthony!
more of this type of testing . just for fun
Yes indeed – thank Chris!

I got 8/8 but I’d rather take this before the session cold & then again after and compare results.
Great idea – I will implement a pre-test for the next session. And of course you can take the exam again after the session if you like!

Yes – love that Keith Barker analogy. Check this one out that sticks to the pizza concept! I did not fact check it – but just at a quick glance – it sure is clever! https://www.versatek.com/blog/you-wont-believe-what-the-osi-model-and-pizza-have-in-common/
