ITs very good stuff tokow : I will create aosme tools from this stuff and give to the large language model : as i have noticed that we dont need to be the "hacker any more " or model or GPT can do this work also and when faced with failure it will keep penetratio testingn : I personally started i networkng but ended up in AI !
This got me to explore 802.1x more closely as BPDU Guard is necessary because 802.1X does not have mechanisms to block or filter BPDU traffic before authentication. By enabling BPDU Guard on appropriate ports, you can protect the network from BPDU-related attacks before 802.1X authentication takes place. I just love your videos as they always make me rethink the fundamentals!
Love it! I highly agree with your idea that learning with actual devices is better than just simulations. It particularly helps with troubleshooting skills, since inevitably in your lab you’ll plug in something wrong or have a bad cable etc. and have to figure out the problem. I would encourage anyone studying for CCNA to get your hands on some real equipment if at all possible. The old gear is quite inexpensive and readily available in most places, and you can build up a small lab for very reasonable cost.
Agreed. If you can afford it, buy physical equipment. If not, use Cisco Packet Tracer and watch my videos 😀 I've spent thousands of dollars on equipment so people who cannot afford to can learn with me.
David, your content has been an absolute treasure, and I cannot express enough how much value I’ve gained from your videos over the past 10 months. I’d love to see a detailed, comprehensive video on the evolution of antivirus technology-starting from its early days to the most cutting-edge advancements. It would be fantastic if you could take us through this journey step by step, from the basics to an expert-level understanding, and perhaps even feature insights from industry professionals. Sending love and appreciation all the way from India-you truly are a gift to us!
What I like about Bombal is he is articulate, precise, and speaks with a degree of confidence and clarity. I have half learned a lot of things over the years from Udemy but am frustrated when thy don't respond to queries about common problems or problems that arise from the tutors skipping simple but vital steps that result in inexplicable unnecessary errors. I have discovrred this is because the people who produce those lessons offered on Kali want to direct you to their private teacng portals where they charge you an arm and a leg.
Love!!! that you demonstrate in a practical manner so we can test it and apply it to our work environment. You have a big talent to teach technology in a simple way.
I am using real devices in my Complete Practical CCNA course - watch this video if you want to learn more about what I am doing: th-cam.com/video/ywB7FH2MI9k/w-d-xo.html
Good topic. Showing the importance of understanding the meaning of the command/configs. Because and also the converge of the network is a real issue, we should avoid changing our network topology in any case. this kind of topic push us to be more precise on our settings. Thk
David Bombal has perhaps the best network security & cyber security channel on TH-cam. OTW is correct when he makes that statement. David please continue your intelligent & intuitive cyber security tutorials. You provide a wealth of cyber security & network security education via your website & TH-cam channel. Thank you sir. Best wishes.
Its the most genuine, that's for sure. Too many other "creators" out there just looking for some quick clicks and fast bucks. All flash. David is concise and coherent and sticks to what he knows. That's what I like about him and his channel.
I don't understand most of what you are discussing but your presentation makes me want to watch nonetheless. It must have taken you a lot of time and effort to prepare your videos to have this high quality. You're one of the few inspirations I have in content creation. Thank you for always sharing highly valuable contents🙏
Was just wondering how is this the first lesson in this course? Don't quite understand the contents of spanning tree in order to understand this video. Regardless I love your content dearly and highly appreciate your teaching skills. Thank you.
This isn't the first lesson in the course. I'm covering some of the v1.1 changes as people who already have my courses have been asking for them urgently. Don't worry - I'll be posting the start content very soon as well as the v1.1 content people are asking for 😀
Love the content, David. I'm taking it the course will fully be on David Bombal Tech? Also, will the videos roll out over time or come out all at once? Thanks!
HI David I doing my GCSEs right now and I dont know a lot as you know they teach like basic stuff , and I was thinking If you can make a series for beginner for hacking , I guess other people wants it as well and I just started seeing your CCNA course , thank you for that Its really awesome .
Beginner content coming to the series very soon. This isn't the first lesson in the course. I'm covering some of the v1.1 changes as people who already have my courses have been asking for them urgently. Don't worry - I'll be posting the start content very soon as well as the v1.1 content people are asking for 😀
I have completed your 80 Hrs CCNA course from udemy. Just INCREDIBLE, AMAZING and whatnot I say.❤ Please create CCNP and CCIE courses as well. We need your CCNP and CCIE knowledge.
Intelligence increase 😜 Thank you for showing this on this equipment! Most people cant afford to have this stuff laying around in the garage to mess around with 😂
THIS IS GREAT WAY TO EXPLAINING NETWORKING OR ANYTHING RELATED TO ETHICAL HACKING... THIS MAKES BRAIN TO GET IT IN EASY WAY... BTW CISCO FREE LAB TUTORIAL ISN'T WORKING FOR ME EVEN I HAVE TRIED WITH MULTIPLE EMAILS...
This series is awesome, and as a visual learner just what I need to learn the CCNA. I was wondering: Is there a reason why root guard isn't enabled by default?
Nice tutorial and definitely the right approach to have so real life example instead of just theory. I dont know what group you are tageting but this is nothing for beginners if you intended it to be.
The full course will be published on my Tech channel here: davidbombal.wiki/freeccnayt - I'll only be posting some of the content on my main channel (in other words, here).
Wauu , David Bombal esta a responder a todos comentários ele é diferente de outros youtubers que os canais são fantasmas sem interação real com o dono, eu sou fã do seu trabalho e o aprecio bastante desde o ano passado. Saudações vindo de Moçambique, você me tornou um cyber segurança melhor 😅 i love you
Thanks very much, much appreciated for the video however, please try to do a video with more than 1 vlan and etherchannels on switch so it can be more realistic. Thank you.
Hello Sir I wanted your help. Do you have any idea on how to read a sd card as mmc and not as sdxc. I have 2 sd cards which are encrypted on very low level so i wanted to reprogram the csd register but in my laptop it doesn't reads the sd card as mmc instead it reads as sdxc because of that i am not able to reprogram the csd of the card.If you know anything about this please help.
Hi David, I'm new to CCNA and just starting my studies. I'm a bit confused about where to begin. Should I start with the older 100-105 material, or should I dive straight into the 200-301? I want to make sure I understand the fundamentals well. Thanks for your guidance!
The current CCNA is 200-301. The 100-105 is old material, but there is a lot of overlap. The best way to start is the current 200-301 v1.1 course / content and exam.
I want to shift my career to IT. I'm very interested in Linux, networking, servers and databases for last 2-3 years, so I would really love to become Linux sysadmin. Today I talked to my friend who is senior developer and he told me that basically no one wants Linux sysadmins anymore, and that he wishes me a lot of luck to obtain this or any similar role, and that basically the only realistic jr. roles I can count on obtaining are this-or-that variant of developer and software engineer roles. Would you say that he's right?
The CCNA certification is a bit more advanced and does require some previous understanding. I'd recommend Professor Messer's vidoes on the Network+ certification
What’s stopping you from learning the basics? Do you go to a graduate school and then complain to the professors that you need to learn freshmen level material? There’s plenty of free entry level networking stuff out there, my friend. Like the above comment, check out Professor Messer. Also check out Network Chuck. He has good material to get your feet wet before you get to the geekier stuff.

Glad you enjoyed the video 😀
Thank you David, as someone that just finished the CCNA course and am preparing for the exam. This really helps me understand the material better.

Hi david u solve all problems love boy❤🎉
Need to learn python from you, cz your teaching style is easier than others to me.. By the way, is this video a part of the Cisco free course?
That was great David
Thank you
love your content , i was wondering about specialized protocols like PXE protocols to boot an device using these rather than traditional way
I watch you from Syria, you deserve the respect for your efforts, forgive me I speak English little... ❤

Wireless adapter CD is important to hack wifi in kali Linux in mobile
Why is this guard option isnt enabled by default when configuring stp
Gotta put bpduguard on those egress ports
Today video was good but i think we should learn basic first because i didn't understand 😢
The CCNA certification is a bit more advanced and does require some previous understanding. I'd recommend Professor Messer's vidoes on the Network+ certification
