Because the term "IP range" defines the entire subnet... answer A only gives us 26 usable addresses.. it doesn't define the entire RANGE, which is what is asked by the question... this is a very common variation for CCNA questions, where additional information is given (i.e., number of users to accommodate), but that is not the info required to answer the specific question

⁠​⁠​⁠​⁠@@intelligencequestdoes the 26 usable addresses include the gateway?

@@Noob.master6969 it COULD include the gateway... a default gateway is just a usable address in the range which is assigned to a specific router interface, this question doesn't say anything about the devices which are addressed in the space (aka the default gateway), they only thing that matters to us defining the ENTIRE range of address, which is what we have done when answering the question.

We are glad it was helpful!

You can do a few things... first would be to ping from devices that should be VLAN separated, you should NOT be able to ping between them until a route is set up between vlans.

Thanks so much! Glad it helped you!

thanks for the positive feedback! much apprecaited

check out the full video! the video is Mastering the CCNA exam with ChatGPT, I go into much more detail about this question

Dang, thanks so much!! been busy instructing and consulting, but will be back soon!

We are going to have spin up a discord server with more resources, sample questions, sample performance based PBQ's basically all of the resources we have aggregated to teach these classes in person

I'm not sure to be honest, but doorbells circuits as I understand are actually lower voltage at least here in the states.. more like 10-20V

Good luck on your exam! Please, let us know how you do. Glad this was published at the perfect time for someone!

have ommitted the music in subsequent videos!

Thanks so much for the kind words!

I guess the results vary with person. I'm pretty much just starting out in this cyber security field after passing my CCNA, and bought the CompTIA Certmaster Learn, Labs and Practice Exam Bundles for the latest versions of Security+, CySA+ and PenTest+. After going through the materials with thought, and doing all the labs, I took one Certmaster practice exam for each course (~80%), and one Jason Dion Udemy practice exam for each course (~ 85%). With those steps done, I passed all three certificate exams in 3 months on my first tries with final scores each around 785/900. Luckily the Exam bundles have a free exam re-take, good luck!

Thanks I passed the 2nd time. Also realized I didn’t fully answer a practical question the first time. Didnt see some extra tabs that needed to be opened and answered which resulted in my failure.

I'm glad you found it helpful! We will be ramping up our cybersec content in 2024!

That's a great question, and something I should do a video on, typically the new version don't deviate by more than about 20% from the older version in our opinion

@@intelligencequest thanks for the reply! If I already have a network defense background, how well would you say this playlist would help study wise for the exam? I'm slated to take it 21FEB. thanks!

@jedi6185 at thos point I think the channel can help identify strengths/weaknesses for you, I'd definitely supplement with some written content even something like reviewing the CND objectives with a CySA+ book (there is alot of overlapping objectives) might be more cost effective than the EC council text

But isn't that still security through obscurity? What of rogue router advertisements? I understand there are ways to mitigate the threat, but isn't the problem built into the protocol by default?

@@lewwolfgang9958 Funny you should mention that. I'm just watching a video where they point out scanning attacks happen on IPv4, but not IPv6, because the IPv6 address space is too large to make scanning attacks practical. The presenter mentioned the law of large numbers and the age of the universe As for RAs, where is the rogue router? Router advertisements can only come from a local connection. In fact, if you look at the hop limit, it will be 255, which means the RA has not passed through a router to get to your network. To produce 255 after passing through a router, it would have to be 0 when entering that router, which would cause the packet to be discarded.

these are great points, I would argue that the large space is both an advantage and disadvantage from a security standpoint depending upon how the networks are set-up: - Certainly the large space makes it MUCH more difficult to enumerate from an attackers point of view, however this can also make it easier for rogue physical device to pickup and use a valid address in the space, that paired with SLAAC can make it even easier to gain a foothold

to be frank, a light review was only needed, I also used other instructors/professionals as resources, I hope this channel can serve as similar resource for others on specific topics

Awesome work! There is alot of content for sure

Have u taken training from ec of CND??

Thank you very much! I really appreciate the feedback

My pleasure

Absolutely! so in the video above I was addressing L2 segmentation, VRF would effectively allow for segmentation of traffic as it was being routed --> think two sets of clients being routed by the same piece of hardware, but for security, logging, analytics you want each of the client networks have their own routing instances, you can utilize Virtual Routing and Forwarding (VRF) to route this traffic but maintain separation of traffic and routing tables

Thank you so much! Next topic to we'll is Back-ups! (3-2-1 policy)

We will post another Q/A soon, we actually generate most of these questions in house. One of the easiest ways is to Google sample questions on the topic your looking for... typically this will generate some decent results... we are also about to start a discord where we'll post weekly sample questions as well 👍👍

Thank you! The sub is much appreciated!

Thank you very much! We really appreciate the support!

Just got back from conducting some training! I will comment with this info don't worry

I’m planning to take this exam next month. Can you please provide your study resources? Thank you!

Let's GOOOO good luck 👍👍

​@@intelligencequest Did you passed it?

Results? I hope you passed.

Never a good sign when they go silent. I’ve heard of failing it multiple times before passing it. Taking next month and just getting started!

Maybe for those who are new to this field, have heard of both of them (among others) I cannot decide which one to take, because they do not know the difference.

did you pass ?

We are wondering the same thing?!

haha so I just passed! I had failed the first time and was ashamed lol but I just finished up and got through it . . . barely!

Thanks so much we really appreciate the feedback!

Awesome! Thank you!
