    Remembering all the different routing protocols is the hardest for me. I can implement them all fine..but remembering the good/bad about each is a pain. esp ones that aren't really use that much anymore.

    I don't really understanding how subnetting is so hard for everyone. I mean, really all you do is subtract each octet that isn't 255 from 256. Whatever your left with is how much that octet of the IP address can change and still be in the same subnet.

    192.168.1.0 / 255.255.255.192 =

    255 mean 0 change . 255 mean 0 change, 255 means 0 change, 256-192 = 64 change

    so

    192.168.1.0-63
    192.168.1.64-127
    192.168.1.128-191
    192.168.1.192-255

    last IP on each = broadcast. first one's can be used.. anythingelse can be a device's IP basically. and i mean, the only sizes you can end up with is 1 2 4 8 16 32 64 128 and 256 in each octet. not hard, people!

    Is subnetting not part of the CCNA exam anymore ? I didn't see it on the voting list. I remember subnetting and how it related to classful routing and CIDR seemed to be the main hurdle that newbies had problems climbing over.

    I personally voted for access lists, btw. Access lists and things like spanning tree and VTP seem like some of the most important things to know on the day to day job given that it's not normal to change the "routing" settings on the core routers on a day-to-day basis.

    I think ACLs are the most difficult and the rest to me really is cake!
    Where to place the ACL which direction (in/out) etc....you have to really play with them a lot! And then it comes to you!


    802 exams take out ISDN there is no such thing on the exam. well in real life there I am sure still is

    My first PC (actually a microcomputer - IBM coined the "PC" description) was a Radio Shack TRS-80. I got the "big" one with Level 2 Basic and 16k of RAM. $999.
    Standard version was Level 1 Basic and 4k of RAM.

    Our company mainframe still had the iron core memory.

    It's still on the exam and in pretty much every other question. In a lot of cases it's kind of a secondary part of the question being asked. By that I mean it doesn't actually "subnet this..blah blah blah" but in order to answer the question you will have to subnet.

    Hmm, for me I think that subnetting and STP have been the hardest (I take my CCNA exam in the morning).

    I've found everything else to be pretty simple as I have been doing alot of the internetwork expert core technology labs from the volume I workbook that they have for the CCIE. This product is excellent and helps you to really understand the technologies. It'll also come in useful as I work towards CCNP and hopefully CCIE!

    Guess I should see how tomorrow goes first

    IMHO: NAT should have separate option in poll

    I started the ICND2 book last week. So far, STP & VTP have been the hardest for me. It just took a while for all those details to sink in.

    The ICND1 book was easy. The hardest thing for me was subnetting, but I got it down now.

    I agree, I have been studying switching basics and intermediate routing for the last week on and off, and have got a pretty ok grasp of ospf, vlans and what not, but am kinda confused on stp, and the advanced stp(can't remember the term, but its faster cause theres no 50 sec downtime)

    At the begining of CCENT, it was subnetting. Different books showed me different ways of doing it, so it took me the longest.

    In ICND2, NAT/ACL looked scary, it took me a couple weeks to feel really comfortable. I even made myself a few flash cards to take them everywhere w/ me.

    From Todd Lammle:
    The reason people struggle so much right now is because they do not understand the NAT overload commands enough. Be sure and be able to configure NAT overload in your sleep, and be able to subnet without having to think about it..

    but i got 100% in each chapter (Bridging/Switching,7-layer OSI Model,LAN Technologies,Basic Router Management and Configuration).. except Access Lists

    in access list i got only 65%....

    WAN was my main issue when I was studying for the CCNA. Glad I got it all figured out in the end though! lol Frame Relay was my nemesis.

    I would say it was subnetting.

    Not so much because I found it hard, but it was the first think I really studied and previous to that I had mostly worked on pure switch layer 2 environments. I also only knew subnetting as a classless activity, so I had to relearn in things like eigrp that Class is still important in auto sumorisation, and to not forget it exists. and that you can have issues sub/super netting across the class boundaries.

    However once I got the fundamentals of ip addressing and the OSI model down. The rest all seemed common sense.

    I have some issues with supernetting and subnetting in general, especially in class A....class B is ok and class C is cakewalk....

    The hardest topic to study for CCNA?

    IPv6

    I am not kidding, it is hard to learn after you master your IPv4 enviroment.

    I'm with you there! I seem to skip that part in the book or video series and move on to something else. Even when I go back and go over old stuff, I still skip the IPv6 material. I just can't get my head around it, and it doesn't interest me, even though I know that it is the future and I will have to learn it eventually.

    I'd rate them all by how long it takes for the information to go from text, into memorized ideas that can play out logically(and correctly!) inside my own head.

    IPv6 certainly is a doozy, but as for the choices in the poll, I'd have to give it to WAN.

    WAN technologies are hard for people to grasp, probably because the first time they've seen anything near what's tested on, would be studying for CCNA. Most of these concepts were easy to learn, simply because I've seen them before in one form or another, but IPv6 and WAN are just things I don't want to deal with!

    ...of course I'll have to though.

    I can't believe that I still haven't voted.

    I have to say access lists because it was a pretty tough thing to get down and they're used EVERYWHERE.

    Access lists beat me up the first time I took the test. I just can't remember where to put standard lists and extended lists plus putting them on in-bound ports or out-bound confused me. I studied that more than anything and destroyed those questions on my second try but WAN got me from behind. Third-time's a charm I suppose.

    none - I am a soon to not be unemployed single mother of twins but damn it, I can subnet you under the table

    I see I am in good company - I chose WAN technologies too. The easiest parts for me are subnetting and the OSI model. Basic router/switch config is not too bad either.

    This is strange but the hardest topic for me is ACL because only of figuring the direction. inbound or outbound. I am always confuse with this.

    Subnetting I got down, what I really did not like was supernetting and route summary.

    But to be honest, I really don't think any of the topics were hard on the CCNA. What is hard about the exam is the amount of information you have to know to pass the exam. I am glad that they made 2 exams out of it because it is a lot of information to retain.

    My two cents on the topic.
