I just PASSED the Network+ 008 exam primarily using this video series. The 7-second chart with octlet 2,3,4, magic number and subnet SAVED ME on ~10 questions. PBQ's were based on understanding subnetting and CIDR for "least number" of IP addresses in a subnet. Thank You!!
Thanks for sharing. I'm working on my school's Network+ course, and will be taking the exam come August. Good to know.
Congrats on passing!
Can I borrow some data for my subnet?
How much do you need?
Just a bit.
Time to get back to the grind! Thank you so much!
19:42 Lol imagine walking in to take your exam and the god of Comptia Exams is arguing with the front desk to bring in his own dry erase marker.
What does this mean? Do they not provide the paper and pens or whiteboard and marker?
@@Chris.kovacs guess you didn't watch the whole video. :(
I LOVE IT! Such a funny visual.
It is a great idea. Ensuring you know it's got enough ink in it, and has not been flattened by some heathen in past tests. I am very picky about markers. I want my Sharpies and Paper Mate Flairs to keep their sharp tip for the length of the marker. haha
I appreciate that you gave a lot of examples here. I like this seven-second subnetting rule the most, I want to do as much practice with it as possible.
you couldn't have uploaded this at a more perfect time! just got to subnetting in my net+ book, it wasnt explained the best in there but now i feel super confident! Thank you so much!
I've spent probably close to 2 months chipping away at understanding subnetting. The time was well spent after finally watching this video -- it was a bear to get through, but this method put a nice bow on it all.
Any resources in particular you'd recommend?
Yes, please tell us because I still don't understand...maybe I'm slow
This video finally made it click. Seven second subnetting is definitely made for me. Doing all the mental math make my brain hurt. 😆
The course one of the primary resources to pass the Network+ exam. Thanks Professor Messer for providing such great contents.
I've come back to this video severall times during my revision. Great content, thank you
I got to rewatch this!
This was very helpful for ccna settings
Another winner! Practicing my charts now!
This really improved my understanding of subnet calculation. Thank you, sir.
I had to watch this video a few times and write very detailed notes before the lightbulb went off, lol. I was able to figure out how the calculations worked and its been smooth sailing since then! Thanks Prof!
Man, when that lightbulb clicks!! 🙌🏾
Making the charts from memory looks daunting . Seems silly you can’t have the chart for the tests. I mean in real life you can make a book with all the charts and stuff to keep with you while working,
in real life you also have google lmao
I wrote the chart when I went into my test and it helped me pass
the chart itself is very simple: count to 32 in rows of 8. count from binary 10000000-11111111. do 2^1 to 2^8. do 2^7 to 1. memorizing it takes a few minutes of writing it down several times, mostly just the binary part.
Halves and doubles - not that hard
It seems that way, but once you start writing it, it’s a breeze
That method is super great! !! From now on i will use it!!!
Very nice explanation. I have trying to use the magic number method and just like you, when there are a whole bunch of subnets to figure out, my math might get a little off.
Thanks so much, i love you I understand now you are a lifesaver
I remember the 4s by thinking of election years 76, 80, 84, 88, 92 etc
Your Magic # chart is my go to chart.
I'm glad everyone is getting it. This subnetting has my head is spinning I want to go more cyber security route, but I know network is needed I will keep watching.
thank you
Fantastic!
Confused on min 11.15, Can we get the broadcast 127 without the table on the bottom?
Very nice
Does anyone know how to use this method for questions asking how many hosts and how many networks?
Pl also guide important bullet points to pass CCNA and how to remember subnetting. I wish to clear the certification.
My biggest struggle with dry erase isnt the pen tip... its having to try and write it out with my right hand so I dont erase it lol
Lefty's of the world feel your pain, brother.
So do you pretty much have to memorize the charts? I don't think you can bring them into the exam so you'll have to remember them and draw them yourself correct?
Will examiners let you draw these charts before the exam starts? Or is the clocking ticking??? 😦
You are only able to make notes after the exam clock has started.
I feel like I'm not understanding the "Addresses" part of this table, can someone explain it to me?
What do they represent?
Is subnet id the same as network address?
yes
Taking my network plus exam in august, is the seven second subnetting method required or can I stick with the magic number method?
So basically 255 and 0 are On and off. Hence why we bring down the 255 and not when it’s 0. Because it’s on and off.
For the exam, will they allow us to use calculators for the simple math? I’d like to make sure my Boundaries chart is accurate as I write it. Also, how much time do they give you beforehand to write down your charts from memory?
You don't get time beforehand you have to write it during your test. So say your test starts begin writing this maybe it takes five minutes then you took 5 minutes of your test time to write it out. You aren't allowed to write things down before hand because it could be cheating
@@AlainaAMenace So you’re saying he actually recommends you take YOUR TEST TIME to write out that long, God forsaken Boundaries Chart during the test? That’s just fantastic
@@jakepayne2985 it's really not that hard to do practice writing itnout you'll get faster and remember it easier. I didn't create the exam rules I'm just telling you that's what I was told when I went and took the A+ and earned my cert
@@AlainaAMenace you get 30 mins to write down the stuff before the test.
@Sebastian Lisowski when I took my exam this wasn't the case. You had to write down any notes during the test which doesn't take too long. The questions themselves can be answered in a few seconds besides the pbqs so it's not that hard
I....I actually understand this. And have been able to do it without cheating back to the videos. Areyouawizard.jpg
