Comments by "Javier Flores" (@JJFlores197) on "FREE CCNA // What is a Network? // Day 0" video.

  1. I'm not 100% sure, but it looks like his site just links to these videos once you pay for it. Normally, it wouldn't be that bad of a deal, but his CCNA series is very far from complete. There is absolutely no way anyone can pass the CCNA with this series alone and no outside resources. Its not a bad video series, but there still a lot of information (and I do mean a lot) that he hasn't covered. He hasn't even shown you how to setup a Cisco router or switch. That's pretty important to know how to do if you're working on Cisco. So far, his videos seem to focus on general network knowledge. That's fine, but its not enough for the CCNA.

  2. Its technically called an ONT (optical network terminal) instead of a modem. Its job is to convert the light coming from AT&T's network into electrical signals your router can understand and vice versa. I think newer AT&T Fiber installs merge the ONT into the gateway so you only have 1 unit instead of having a dedicated ONT and an ethernet cable running from the ONT to the gateway.

  3. You can get some general knowledge, but that exam is obsolete.
    2
  4. He already has one. Its on his channel

  5. Anything you connect to your network has the potential for being hacked. This is one of the reasons some people like to create separate networks for IOT style devices or otherwise devices which are suspicious. You can create a subnet and firewall rules that prevent the IOT network from communicating with your main network. There are firewalls that can attempt to identity suspicious network activity occurring inside the network, but those are more advanced to setup and in large networks.

  6. You're better of checking Jeremy's IT Lab. Chuck probably won't finish this series. Its been 4 years and he hasn't really gone into CCNA-specific content.
    2
  7. CCNA is better. The CompTIA N+ is a vendor-neutral certification. Its decent if you just want network knowledge, but the CCNA is regarded higher.
    2
  8. Of course.
    2
  9. I suggest using other CCNA training videos. Network Chuck's videos are good, but he still has a ton of stuff he hasn't gone over. A lot of it is important to know for the CCNA, like how to actually setup a Cisco router or switch. Those are just one of many things he has not gone over. I suggest watching Jeremy's IT Lab. He may not be as exciting or energetic as NWC, but his CCNA series is actually complete.
    2
  10. Yes and no. It has the general basics, but there's still a lot of information missing. Its not a complete CCNA training series.
    2
  11. Dude, you may want to watch the videos. He goes over that information.
    2
  12. I highly doubt it. Its a decent course, but it doesn't go very in-depth. Its more of a high-level overview course to somewhat familiarize yourself with networking concepts. There are still a lot of topics he hasn't covered.
    2
  13. Nope. This is still a very incomplete video series. Too much stuff is missing that is important to know for the CCNA. I suggest watching Jeremey's IT Lab. He may not be as enthusiastic as NWC, but his training series is complete.
    2
  14. With the current state of his videos, no. His 'series' is very far from complete. There is still a ton of stuff he hasn't covered. You're better of watching David Bombal or Jeremey's IT Lab. They may not be as fun an engaging as NWC, but they are much more informative and most importantly, complete.
    2
  15. I don't know if the Cisco-specific knowledge will be helpful, but having a good understanding of networking concepts can be very important in the grand-scheme of things relating to cyber security.
    2
  16. Find a decent CCNA course. This isn't necessarily a bad course, but there's still a lot of information that he hasn't gone over which is crucial for the exam. I suggest watching Jeremey's IT Lab. He's not as enthusiastic as NWC, but he has a complete series that is pretty good. Its also a good idea to be familiarized with using computer systems like Windows and Linux at an intermediate level.
    2
  17. You should also be fairly familiar with using computer systems at a moderate level at least.
    2
  18. If you are trying to get a Cisco cert, you want to use other resources as well. His videos are generally pretty good at giving you a high level overview of different topics. Its great as an introductory course, but he doesn't go very in-depth. He is a good presenter, but just doesn't go as in-depth as he should if he want to call this a CCNA course. There are still a lot of topics he hasn't covered. He hasn't gone over how to actually configure a Cisco router or switch; he hasn't gone over the commands, and many other important topics.
    2
  19.  @Insight-v3f  You're better off watching Jeremy's IT Lab. He has a complete CCNA course. Chuck is a good presenter and very enthusiastic, but his content is only superficial. I'm not saying its bad, but for the CCNA, it has to be Cisco-specific. So far, he hasn't even gone over much Cisco-specific material. You can learn the core basics of networking which is important to know for Cisco, but you'll need a lot more material to pass the exam.
    2
  20. Nope. His series is far from complete. You're better off watching other channels like Jeremey's IT Lab or similar. Network Chuck is a good presenter, but there is still a lot of information that he hasn't covered in this series.
    2
  21. Its not really a modem. There's an ONT (optical network terminal) that he briefly shows. The fiber cable ends at that ONT and then gets converted to an ethernet signal which runs to his AT&T gateway box.
    2
  22. No. Computer networking doesn't require any programming knowledge. Although it can be beneficial to know programming if you want to get into SDN (software defined networking).
    2
  23. Pretty much. The core concepts of networking don't really change much. He's a good presenter, but his "CCNA" course is far from complete. There are still tons of concepts and topics he hasn't covered, so you may want to look at other resources as well.
    2
  24. You ok there?
    1
  25. I highly doubt it. These videos are pretty good to help give you a general understanding of some networking concepts. However, at least with the videos he currently has, there is still a lot (and I mean a lot) of information that is missing. From what I recall, he hasn't gone over a lot of topics, or if he did, it was brief like: subnetting, VLANs, routing protocols, switching technologies, trunking, ACLs, actually configuring a router and a switch, etc.

  26. You have to study for it and take the exam. You don't just "get" the certificate. Here's more information: https://www.cisco.com/c/en/us/training-events/training-certifications/certifications/associate/ccna.html

  27. Every company is different in how they run their IT infrastructure. Some use Cisco, some use HP Enterprise, Ubiquiti, Juniper or basic home routers for small businesses or other brands. Some many have a hodgepodge of random equipment that someone setup 10+ years ago and no one knows what works and what doesn't.
    1
  28. He's a good presenter. He gives you the basic information, but that's just about it. If you want to go deeper into network, you'll need to use other resources. NWC's CCNA series is very far from being complete. There's still a ton of information he hasn't covered and it doesn't seem like he'll ever finish the course.
    1
  29. Not currently. His series is very far from being complete. He hasn't even shown you how to configure Cisco routers and switches.
    1
  30. The CompTIA is a more general networking certification. If you have your CCNA, you should already be familiar with the network concepts. The Net+ doesn't go nearly as deep as the CCNA does in terms of networking. It also isn't vendor-specific.
    1
  31. Its possible, but unlikely you'll get a networking job right out of the gate without hands-on network experience. You usually start from the bottom: Help desk/IT support then work your way up.
    1
  32. Not to be negative, but NWC still has a lot of work to do. He's a very good presenter, but his information (at least on this CCNA series) is still very incomplete and superficial. Its great if you want to learn the basics of networking, but his series name is misleading at its current state. There is still a lot (and I do mean a lot) of material he hasn't gone over which is important for the CCNA exam. At its current state, its impossible for anyone to pass the CCNA with only this CCNA series.

  33. No IT certification really guarantees a job. However, it can increase your chances of getting your job; its not the only factor though. You have to see what requirements a company has for that job.
    1
  34. You could probably learn a lot of this without a computer, but it just makes things much easier if you have one. You don't need anything fancy, just as long as it works. I would avoid Chromebooks. Although they are quite inexpensive they are very limited in what they can do.
    1
  35. You don't necessarily need a CCNA to work in cyber security. If you're not planning on working that much with networks, I would look for Network+ video trainings as they're more generic. CCNA training is intended for people who want to get a Cisco certification and/or want to work in computer networking with Cisco equipment.

  36. A router's job is to connect networks together and route (hence the name) IP packets. A modem connects your network your internet provider's network via phone line (if on Dial Up or DSL) or coaxial cable (if using cable internet service) or wireless (if using a mobile hotspot device or satellite internet). In most typical home and small business networks, the router and modem are 1 unit usually called a gateway or other fancy marketing name. In larger and more complex networks, the modem is usually a separate device that the ISP installs at your main data closet or room.
    1
  37. Do you have any IT knowledge, like PC repair or Windows troubleshooting knowledge? If not, I would start with IT fundamentals. CCNA is not exactly an entry-level IT cert. It greatly helps to already be familiar with using a computer at a intermediate level.
    1
  38. If you want to work with Cisco networking equipment, having a CCNA can help increase your chances of getting a decent paying networking job.
    1
  39. Yes. Its the same waves they use to send the COVID virus to everyone. lmfao 🤣🤣🤣🤣
    1
  40. Probably not. This series is intended to be for Cisco certification. It is far from complete and is not exactly specific to firewalls. It is of great benefit to understand how networks work to understand firewalls, though. I would look for other resources like Jeremey's IT lab. It may not be as 'exciting' and 'upbeat' as this video series, but it is more informational and more complete.
    1
  41. Eh... Not to burst your bubble, but there is a significant amount of content missing for a "CCNA" course. This series is very far from complete and it doesn't look like he will actually finish it any time soon. The series is ok to learn general network concepts, but it isn't enough for a CCNA course.
    1
  42. Can you expand on what you mean by different output on packet tracer?
    1
  43. Potentially, but a lot depends on your potential employer.
    1
  44. That's not how it works. If you have fiber to the home, your provider should have installed an ONT (optical network terminal) somewhere in or on the side of your home. That's where the fiber from the provider comes in. It then gets 'handed off' to an ethernet connection which runs from the ONT to your router. You then plug in a network switch into the router if you need more wired ports. As for using 2 routers, there's no real reason to do that. It makes things much more complex for home networks. What exactly are you trying to use 2 routers for? If you want wifi coverage, you would simply enable AP mode on the 2nd router so that the routing function gets disabled and it acts simply as a wifi access point. On some routers, you may need to manually disable different settings. You have to keep in mind this is a CCNA video. This isn't meant for typical home networks. Yes, you can use fiber with Cisco switches, but this gets more complex.

  45. If you have a local community college that has some security courses, that's probably your best bet. If not, you'll probably want to watch some videos on networking and hacking-specific videos. Network chuck has some pretty decent ones, but he doesn't go super in-depth.
    1
  46. well that wasn't a great recommendation from chatgpt. This course is very incomplete...
    1
  47. Yes I suggest learning about computer networking. You don't necessarily need to learn the CCNA material, but general computer networking will be adequate.
    1
  48. You can see if there's support for the dd-wrt or tomato firmware. That should give it more functionality over the stock firmware. If its too old, it likely wouldn't be worth doing anything on it unless you have a niche use case for it.
    1
  49. Definitely learn and practice as much as you can. Don't get discouraged when you get to something you don't understand. Sometimes you have to watch different explanations until it clicks, just like school. I'd say subnetting is probably the concept a lot of people new to networking have trouble with. Its difficult for some people at first to not only understand why, but how its done. Take notes if it will help you remember the key stuff. If/when you're working on projects, keep good documentation. Not only does it help you keep your stuff organized, but it if you're interested in an IT career, it is good to have this skill.
    1
  50. Its quite a high-level overview. He explains things pretty well, but he doesn't go as in-depth as he should. He calls it "Free CCNA", but his series is incomplete. There are a lot of topics he hasn't covered, or if he did, it was brief.
    1
  51. What?????
    1
  52. Not quite. If by servicing machines you're talking about computers, then not really. This video series is mostly aimed at people who are interested in computer networks and the Cisco CCNA exam. If you just want to work on computers, you don't need to know about Cisco stuff. It does help to understand some network concepts, but you don't need to CCNA certified to work on PCs.
    1
  53. Nope. Not even a bit. There's still a lot of topics he hasn't covered. I honestly don't think he'll finish this series.
    1
  54. 2 LANs connected together via a router.
    1
  55. No... doesn't work that way. Your friend would need to buy his/her own internet connection.
    1
  56. No certification guarantees a job, but it can certainely help. Do you have any previous IT experience?
    1
  57. Nope. Not in the slightest. This "CCNA" course is so far from being complete it really shouldn't be called CCNA. There's still way too much material missing. And you wouldn't really need all of this for 'hacking'. You'll want a solid understanding of computer networking, but you will need to use other resources.
    1
  58. All that is just hollywood nonsense. "Hacking" in movies is completely unrealistic.
    1
  59. No. Its still a LAN. WAN refers to a large geographic area.
    1
  60. Your router has no way of connecting to the internet provider without a modem. I doubt any internet provider gives you an ethernet connection. You need a modem (cable modem or DSL modem) to connect to your internet provider.
    1
  61. At its current state, it is nowhere near complete. There's still a lot of information he hasn't gone over which is important to know for the CCNA. He hasn't even shown you how to configure a Cisco router or a switch.
    1
  62. Yes you can do that.
    1
  63. With what?
    1
  64. No. This series is far from complete. I honestly don't know if he will ever finish his training series. He hasn't even gone over any Cisco-specific material. You're better off watching Jeremy's IT Lab.
    1
  65. Good luck. His series is far from being complete. I honestly don't know if he will ever finish it. There are still way too many topics he hasn't gone over.
    1
  66. Its more of an introduction. This video series is very far from being complete. Its ok if you want to have a general understanding of networking, but definitely not good enough for a networking job. Do you have any IT experience or experience working with computers? If not, I strongly suggest looking at the CompTIA A+ or ITF+ exams first as those are more for beginners. CCNA (this video series) is not exactly meant for people brand new to the IT industry.
    1
  67. Not really. This video series gives you the basics of computer networking, but that's about it.
    1
  68. The thing is this course is incomplete. Its ok if you want to learn basic networking, but there is still a lot more to learn that he doesn't cover. And for cybersecurity, you will want more than the basics.
    1
  69. Apple and Microsoft don't control the internet. The thing is, that a lot of those videos use "hacking" as a marketing term to get people interested in the video. You can almost say its clickbait. There are 3 types of hackers: White hat hackers, gray hat hackers, and black hat hackers. White hat hackers are cyber security professionals who use their knowledge for good. They may work for a company's cyber security team or work for a company that specializes in computer security and use their skills and knowledge to test the IT security of their company or the company they are hired to test. They may also to make recommendations for increasing security and/or providing training. Gray hat hackers are in a gray area. They may not necessarily 'hack' into systems to steal or cause damage, but rather to prove that they can do it. Black hat hackers are the criminal hackers who use their knowledge for their gain or for someone else. Its important to make those distinctions. The thing is that its knowledge. Its up to you as to how you use it. This is an extreme example but doctors can use their knowledge for good or bad even though their training and schooling is usually not widely available. I also forgot to mention that it is very unlikely most average people who try to watch those videos will immediately be able to 'hack' devices. Modern phones have usually good security so it is very difficult, but not impossible, to hack them. Realistically, hacking is a skill that needs a lot practice and knowledge about the target device.

  70. Yes you can do that. Higher end switches have the option to connect to other switches via a DAC (direct attached cable, I believe) so that they can function as a single unit). You can also connect a switch to another switch via ethernet or fiber (if they support fiber connections).
    1
  71.  @zaid2299  Jeremey's IT Lab is pretty good. He may not be as exciting or as upbeat as NWC, but it is much more complete.
    1
  72. I highly doubt it. Do you have any computer experience or knowledge? Computer networking isn't exactly a beginner level subject. Ideally, you need to have a good foundation with computers and the common systems prior to jumping into networking. And unfortunately, these videos aren't complete. There's still a lot of information that is missing which is important to know for the CCNA. You can learn the basics of networking, but it won't be enough for the exam.
    1
  73.  @yourPru  I would suggest learning some general IT knowledge first, like how to install Windows and drivers and general PC troubleshooting and repair. Its not absolutely necessary, but it will greatly help you in general IT skills.
