The biggest thing makes me nervous is time I will learn it but I can’t rush it and I do excessive hours I know one thing if I never get a job I will still continue to learn this and you sir are phenomenal teacher I wish I had your knowledge

Very informative . Your expressions attracts a lot.

I think you and Odom is all I need to learn becoming a networking master

Hi, Did you miss out the firewall rules for vlan 5?

Im committed to cCNA and beyond but I’m pondering getting cct and hopefully entry job and take this as far as I can I have a long story but now that I’ve started last September I got my google IT pro and A+ I love this stuff I’d lived in a shelter and take internship and work for free to get this going it’s the only thing I want to do at this point in my life I’m changing careers I’ve been in along time

WOW! Talk about a challenge. I spent hours trying to complete this lab troubleshooting. I wasn't successful, but after watching you, Keith, and how you went about it, I learnt a huge amount. Thank you again for your tireless efforts to not just teach, but have fun doing it at the same time.

You’re knowledge is incredible I hope to grasp all of it like you one day

why you give internet on management interface

Haha, I tried the lab before looking at the video. After 10 minutes, I found the VLAN issue and all the clients were getting their appropriate IPs. But that web issue got me good, Dan! I was looking everywhere else bar the index page. Loved it mate, real troubleshooting. I can imagine someone doing this in the real world.

You are very good at networking I hope I can understand all of this like you it’s impressive how many years have you been learning this?

thank you

As a native Californian (now in Miami) I am committed to the CCNA. Hopefully by the end of the year!

I like scribblesticks

thank you this videos really helped me , i am stuck in something i was trying to ping from my pc to the vm interface i am not able to do that can you help me in part

Hi Keith, I just wanted to express my deep appreciation for the incredible videos you put together and made freely accessible to everyone. For me, these labs are invaluable as they reveal weak spots in my skills and memory in a very practicable way. Keep up the great work. :)

Thank from Costa Rica, learn a lot!!!

your the best , i was struggling with this via a different video

you are the best..

hey sir its having a pleasure to have you .however tell me when you are working as network admin .i have not idea about the practical work

I Commit to getting Ccna by November

Thank you

With my WD SN570 it just makes contact with the thinner thermal pad. I'll see how it goes. I might add the second thin pad. The thick one is thicker than the two thin ones combined. For people with double sided NVMEs, you might find a thin pad between the drive and the PCB makes contact there too. With my single sided NVME drive, none of the pads were quite the right thickness to do that and it's not really necessary. So I'd say it's a bit fiddly, but following the Sabrent video and pictures, or this video, makes it easier than trying to do other odd things with the components. The instructions in the box though aren't great, so I can understand why some people did odd things!

Thanks so much for this info Keith.

is it like RR in BGP?

Hey Keith! Great content. When I am creating a virtual disk the only write option I have is “write though” instead of “write back” on your video. Does this matter?

Thanks for the Advice!, Notepad has changed my life, 100% recommend 👍

Keith, Please may I also have the link to the ova that you used way back for the F5 Big IP load balancer

Thank you so much for the videos Keith

Hi. I didn't understand why you set 10.10.0.100 as a default DNS, instead of 10.10.0.19. Thanks

What application you use in infographic

I like your style! Thanks for sharing your knowledge. I have a similar setup at home that I built for my CCNA and beyond studies.

Does anyone have any recommendations for beginner friendly labs to configure physical Cisco switches rather than packet tracer?

Why no one talks about the multicast MAC address? I had to search several sites to understand how the NDP works at layer 2. Everything sounds great at layer 3, but a normal switch will only forward frames, what is it supposed to do with an IPv6 packet destined to a solicited node multicast IPv6 address?

Thanks for this fantastic series, Keith.

looks like an old 90's Punch amp.

Hi, may I please ask why Wireshark shows the ARP request's Target MAC Address as 00:00:00:00:00:00 when we're actually broadcasting to FF:F:FF:FF:FF:FF? (Video Time - 7:30)

I whole heartedly agree Keith. I got my CCNA and my ISP not only uses Cisco but also Alcatel and Fortigate for the data center. So now I'm learning Nokia and going for the NRS1 certification. Had to put off renewing my JNCIA as we don't do Juniper at my level.

Hi Keith, thank you very much for this awesome video! In the description of your network topology at 1:36, you decide to use a fortalink but why does it require two ports on the firewall and also two ports on the switch? Couldn't you have used simply an ethernet/sfp cable to connect between the firewall and the switch? The same goes for the connections between Switch 1 and Switch 2.

You are the best Keith!! I am a fan of all your courses in CBT Nuggets.

For some reason i cannot select f2. ,f8,10 etc just selects it but never opens menu

if one day i get a job and have enough money to travel i have to meet you

@2:26:00 WiFi6/WiFi6e is not full duplex but WiFi7 with MLO actually can now support <some> full duplex.

Can I have the same SSID and password with the Google mesh? Or do I have to switch and reconnect all my devices?

My ADHD makes study for these exams at the last minute, within two weeks. I repeat the same process each year. I already did it with CCNA, three years in a row that I study in depth within the last two weeks and never complete any of the study materials I invested in. I retake the exam for the third time this week and I failed again for the third time studying consistently for a year. The time blindness hits me hard and I continue to time warp the entire year without looking at my CCNA books, labs, and practice exams. Luckily, I had free vouchers for the last three years, each year from my job. But I will have to take it for the fourth time out of my pocket. Although I did manage to pass the A+ and Network+ cramming for the last two weeks, but with CCNA it is impossible.

I committed to getting my CCNA

this topology looks only can tolerant port failures, not switch failure

Just passed my CCNA on the second attempt today. If I had found your videos first I doubt I would've failed the first time! Subnet Saturdays helped me sooooo much. Your teaching style is great, thanks a lot!

Great video. You're teaching style is so much better than most. Thank you.

@KeithBarker May I please know the source you got the shirts from and which version of the shirt it was?

Can you make a series for IT newbies?? There are so many “why” moments when watching this series!!
