ERRATA:

To be fair, lots of other Cisco documentation and CCNA study materials state that this command is necessary, but that seems to be a misunderstanding. Try it out on some Cisco routers and you'll see it's not necessary!

Hello Jeremy and anyone finding this course helpful. I passed my CCNA last night and I can say that this course helped more than any other resource. For those preparing, who have taken CompTIA, this is far different than them. I had 86 questions and 4 labs, you can only move forward in the test, no flagging for review, no going back to change an answer so be prepared for that. I commented on the NTP video because 3 of my 4 questions had NTP setup with peers and clients. Two had setting up SSH connections. One was all VLANS and trunking. I got none on OSPF or STP which is where I spent the majority of my practice after reading about others experiences. I also used Boson practice tests. I also had quite a few regular questions on Wireless LAN setup and SDN. SDN was actually my strongest category which was strange since in Boson tests, Security was always my strongest, in the exam it was my weakest. Either way, thanks Jeremy! These are the best video resources and I commend you for taking the time to create these and all the resources and labs and provide them for free.

whoever's studying and has come across this video on NTP... don't sleep on it! I was super confident on my ccna exam but I skipped over NTP during my studies because I felt it wasn't a huge topic to go into... i got like 5 questions that were related to NTP and I'm pretty sure I bomb'd them all. I got a 823 because of it and just missed the exam by 2 points LOL. I'll get it next time.... !!!

Being your channel members for years, I now can finally say i passes my CCNA exam last week !!!
thank you so much Jeremy for providing this complete course as I wouldn't have made it without your effort
To those who are preparing CCNA, just wanna share with you guys that the exam would contain 2-3 lab question which need you to do some hands on configuration, mine was involving in OSPF, ether channel and NTP and of course they carry huge portion of the marks so be prepare if you wanna score well : )

Jeremy your course was instrumental in helping me pass my CCNA today! got a score of 895 first try!

Welcome to Jeremy's IT Lab, today we'll learn about Jeremy's country of origin & Country of residency. Jeremy was born in Canada, but this is an old technology and nobody uses it, Jeremy moved to Japan because their network is much faster.

At this point i am just overwhelmed. I feel like the amount of information stored in my brain will flood out just like a switch floods out unknown unicast frames. So many mac addresses to remember and so many commands that are, is it just because I have not started my revision ( as i plan to finish the series first and then revise myself by using boson and revise the topics whose answer I fail to answer correctly. Ps I USE THE ANKI FLASH CARDS but at this point i think theres so much to remember and also 20 more videos info, commands, concepts.

As a long time network admin, time synchronization is critical to a healthy network across all devices! Others have thought of skipping this topic. I would suggest giving this video the time it deserves! (pun intended!).

[SainiranjanGurijala]

Great video and one thing I would like to add is NTP dependency on L4 protocol and port. NTP uses UDP port 123 as both source and destination ports. It’s a fancy port number and easy to remember.

Thank you for the great series! Passed my CCNA three days ago

Thank you so much Jeremy, your videos are always the best, may God give you the strength to keep on supporting us with your super informative resources.👏👏

[AbdulazizAl-Othman]

I love you, Jeremy, you are the greatest and the most helpful and generous person that I ever met, my life will change because of you !

[shotachalauri]

Thank you Jeremy, your lessons are very simple and very productive, they helps me very much. I am going to pass exam after a month and it breaks my heart that i can not complete whole course :(

[bethramanthony]

Many thanks Jeremy. Your lectures have helped me alot to understand networking. God bless you

[ranjanadissanayaka]

Finally finished this topic as well. most difficult thing about this topic is packet tracer don't have some of the commands. So, I had to practice on Cisco CML.😀

[wilfredcastaneda]

Thank you Jeremy for uploading all of your videos. I watch them all. I am confident understanding related to networking. However I'm working on Fiber Optic System. More power to you Sir!

[alicisco]

Default stratum level of router's internal clock is 7

[BR-hptm]

i think there is a typing mistake at 33:41, bottom line ntp peering configured for R2, it should be R3. Correct me if iam wrong. :)

[Zalenmoto]

Ahh one more video before I go take the test! Thanks Jeremy! Wish me luck!

[pc]

Thanks, Jeremy another great learning video! You and David Bombal are my inspiration to keep learning in regards to networking. I'm looking forward to your next video any hint? 😊✌
