I get reverse and hosts but not too sure about networks
I get the right answer, but feels confusing

Example
216.21.5.0 /24 – need 5 networks
I use 2^ table , so 2^3 = 7 (need 5)
So subnet = 224
Therefore 3 bits for Net and 5 bits for host

Is that how u do it ?

If I may help NeilG..
5 networks needs 3 bits, (5 in binary is 101). So you have to reserve those 3 bits in the network (11100000), which would make the subnet mask a /27. So you are correct, 3 bits for network and 5 for host.

Say it needs for 6 or 7 and even 8 networks (when asked for powers of 2 networks, subtract 1), the result is the same thing in that 6 and 7 requires 3 bits (110 and 111 respectively). So 3 bits for network and 5 for host giving you a mask of 224.

subnet ranges are:
0
32
64
96
128
160
192
224

@Denis: For the sim, you will only get some points if you can’t solve it completely.
For other questions you will not get any points if you can’t solve it completely.

216.21.5.0/24 – 5 nets
5 > 4, 5 < 8, 8 = 2^3. 2^3 is 224
increment 256-224 = 32
nets are x.x.x.0, x.x.x.32, so on…

@jeff
in PT add a server, configure it with an IP, add a few HTML lines to it and you have yourself a website simulated in PT. you can do this with DNS too. need an example? i can do it for you if you ask me to

use gns3 to simulate a real environment, you will get basic switch functions though…
you can use a vmware workstation to act as network host. this is far better than the hosts emulated in PT.

Ok tx
So I got it the same way as everyone else

Hard work trying to get the CBT way out of my head !

@Xallax
you have a youtube channel or something? If it’s worth your while, an example would be great. I’ve never used GNS3 though. Felt comfortable with PT right away so I never installed GNS.

@jeff
no sir, i’m not a trainer, i’m a trainee just like everyone else here 🙂
tell you what. i will install it fresh and write down the steps as i do so. once i’m done with everything i’ll post the text here.

@neilg
no, don’t just forget that, adapt it. you came here to learn, not to forget.
just think in terms of powers of 2, write them down on a sheet of paper if you haven’t memorized them by now.

a few IPs and network masks for you to practice on:

203.48.208.249 /24

219.110.4.168 /30

212.45.63.64 /26

216.190.98.61 /26

125.250.150.25 /8

answer this:
what’s the network address?
what’s the broadcast address?
what’s the subnet mask?

try doing it in you mind, write down only the answer

Work off a Blackberry, takes forever to type LOL

203.48.208.249 /24
255.255.255.0
X.X.X.0 – Net
X.X.X.255 – Broadcast

212. 45.63. 64 / 26 (trick question LOL)
255.255.255.192
x.x.x.64 Net
X.X.X.127 Br

216.190.98.61
255.255.255.192
X.X.X.0 net
X.X.X.63 br

125.250.150.25
255.0.0.0
X.0.0.0 Net
X.255.255.255 Br

very good.
need a few more to practice on?

@jeff
1. download link:
http://www.gns3.net/download
i got v0.8.1, the latest
size: 128 MB, fair speed of about 1 MBps

2. install it with everything it has

3. REMEMBER: CISCO IOS IS COPYRIGHTED.
some information can be found here: http://tinyurl.com/6jypg4
you can’t use gns3 unless you have an IOS. it’s your job to get it…

4. open gns3 (shortcut on desktop), create a new blank topology, name it Test or whatever you like

5. hit ctrl+shift+i (or go to edit / IOS images and hypervisors)

6. import the IOS image (it’s something like ‘c1700-entbase-mz.124-5.bin’)
6.1 set the platform type equal to that of the IOS image (c1700 in this case)
6.2. select the model (i’ve selected 1710)
6.3. add some RAM to this platform (i gave it 64 MB)
6.4. save/close

7. drag a router for which you configured the IOS to the topology (center of the screen – between Nodes Types, Topology Summary and Console)

Nah its all good now !

Downloaded howtonetwork subnet question generator to practice on

Now i can practice till it comes out my ears LOL

Thanks again for all your help !

I now also believe it can be done in seconds !

Does anyone have an idea what kind of sim questions to look for?

thanks xallax! What was your overall perception of the test?

I’ve used primarily the cisco press books, exam cram, just started looking at 9tut.net.

icnd1 is easy.
the most important thing is subnetting. if you’re an ace at subnetting then you’re as good as certified.

i used todd lammle’s book, cbtnuggets videos by jeremy cioara, packet tracer self-made topographies to get familiar with the CLI, lots and lots of VCEs

@Xallax, I think you are putting a huge misconception in a lot of peoples heads to say that ICND1 is easy because it is not. If it was that easy everyone would be passing. It is not that easy and people should take this exam very, very seriously.

@bigd
yes, my information was incomplete: it’s easy IF YOU STUDY.
thanks for pointing that out

When U KNOW and UNDERSTAND the material any test is easy

Cisco certification requires willingness to learn and “love” of networking

By love I mean you like what u do, if u like what you do you will spend more time doing it, and in the process learn more

I think CISCO want people to hear how difficult this test is, that way people study much harder, actually “over” prepare, which is good, cause then they know all the material

practice,practice understand and then practice some more

Passed today with a 950. Just study your materials well. I used cbtnuggets, odom’s book, the cisco learning center practice exams, pdf’s shared on cisco’s learning center, this site and some vce’s. I self-studied for about 40 days and I learned the material well. Master subnetting. Good luck to those who choose the 2 exam track towards CCNA. Hopefully someone hires me as a CCENT.. if not, icnd2 in about 40 days too should be fine.

congratulations jeff!
go to the icnd2 topics now 🙂

Actually, I was reading some stuff about VTP on 9tut.com and VLSM from cbt nuggets even before I passed! Good thing I passed on my first try. How long have you been preparing for ICND2 Xallax?

since march, i was ready in may. too bad i’m not ready financial so… it’s on standby at the moment.

You should loan the money.. 125 bucks ain’t so bad. I actually paid almost 20% higher since I didn’t have a credit card. You’ll reap the benefits of CCNA and pay it back in no time.

my story is a bit different and i don’t want to post drama here. i will take the icnd2 exam and i hope i get a perfect score on it too.
meanwhile… i get to go through some of the more advanced topics, take care of my little website and prepare for going to work abroad.
i’m not rushing 🙂

you haven’t mentioned your website before..

Does anyone remember if there is a question on the exam regarding the actual colors of wires in a straight-through or cross-over cable and where they match up?

BigD

Just read up on T568A and T568B
A Crossover uses A on the 1 side and B on the other

If you make long network cables its very important to use this standard !

I speak from experience LOL

@Neilg, what are you referring too regarding T568A & B?

@neilg
yes, they could ask you that.
you have 4 colors: orange, blue, green, brown.
you care about orange and green.
t568a starts with green, t568b starts with orange. always starts with half-color.

A: white-green, green, w-orange, blue, w-blue, orange, w-brown, brown

B: w-orange, orange, w-green, blue, w-blue, green, w-brown, brown

one more thing: cat5 uTP cable (the one most often used) spans for no more than 100 meters.

reference: http://en.wikipedia.org/wiki/TIA/EIA-568#Wiring

oopsie, was intended to bigd. my bad 🙂

@Xallax, thank you sir, can always count on you. LOL

@bigd
it was hard for me too to remember all that non-sense… colors, wires, pairs…
get a 1 meter long cable, 3 or 4 jacks, a crimp tool.
try creating a new cable to go from your home router (i’m sure almost everybody has one of those little boxes with wireless, wan and 4 switch ports) to your pc.
if you do it right… cheers. now mess up one end of the cable and create a cross-over.

practice is the best solution for cabling 🙂

Folks … Took test three days days ago … Make sure you do Drag and Drop Questions of CCNA-802 … a number of them showed up on my test … 9tut is kewl … but You as a test taker would require more than the lib sims …. sims are good as a learning tools … my perception is … Cisco may have changed the test for one reason or the other … Study you Subnet, Ethernet Cabling, and Ofcourse MAC Addressing traversing through a network! Good Luck!

@ nueagle121, which exam is the 802?

@ nueagle121, one more thing, when you say Mac Addressing traversing, can you be more specific? I am taking the exam in 2 weeks and trying to cover all the bases. Thanks for any help….

@BIGD

I just took my exam yesterday. I’d say about 60% were from vce’s and stuff in here. Just know your material well and you should be fine.

@Jeff, what did you mean by Mac Addressing traversing? Thanks for getting back..

I didn’t said that but by traversing he meant what MAC Addresses will be used to forward a frame. A good example would be the ARP testlet on this site.

@bigd
802 is the ccna 2in1 exam (icnd1 and icnd2 topics in one exam).
“Mac Addressing traversing” must be the process of data going along the LAN. we use MACs locally, IPs once we leave our (sub)network
jeremy cioara has a nice explanation of that using the OSI model in one of his ICND1 videos.

BigD
T568 A and T568B is the standard

U can actually make a short cable (say 5m) without following the std and it will work fine, but start making long cables and u will have intermittent problems if u dont follow the std

Years ago we moved computer rooms, I had to make network cables for about 30 Servers, 10 switches and Hubs, 20 routers, didnt know about the std and boy did we have some weird problems
I researched lots and found the std, had to re-do all those cables and all the connection problems stopped

If u wonder why that specific combination, there are a few reasons, but my reason, cause no matter where I am, I can take a cable and look at it and know if its properly made or not

Once you know it you’ll never forget it, I didnt work with it for 7 years (left IT), then one day I had to make one for a friend, immediately knew how to make it

Get the CBT nuggets ICND1 DVD, will answer most of your questions

@xallax, Love your method of working out the subnets…just one question

In this bit—————

“long story short: 256-the value of the bit that is incomplete (256-252=4)
4 is the increment. i start counting in blocks of 4, i get
x.x.0.0
x.x.4.0
x.x.8.0
x.x.12.0 <– my subnetwork
x.x.16.0 <– i subtract 1 and i get the broadcast address, x.x.15.255"

How do you chose your subnet work….is it the nearest number to the 14? of (12.13.14.15)
once i get this bit i'll have it down.

cheers..

U choose the next biggest nr, then apply that 2^nr to get your subnet and incr

2^0 , 2^1 , 2^2 , 2^3 , 2^4 , 2^5 , 2^6
1 , 2 , 4 , 8 , 16 , 32 , 64

Example
50 Networks, therefore choose 64, which = 2^6
So reserve 6 bits NETWORK bits (on)
So
Therefore my increment = 4
Subnet mask = 252

For 5 networks its 2^3 so reserve 3 bits
For 15 networks its 2^4 so reserve 4 bits
For 100 its 2^7 so 7 bits
And so on

Your subnet mask for your example would be
255.255.252.0
in binary
X.X.11111100.00000000
1=networks
0=hosts

So networks =2^6 = 64
Hosts = 2^10 = 1024 – 2 = 1022

@neilg
please no strings of 1s and 0s!!!
still, i guess you’re doing it in less than 30 seconds now 🙂

@osiris
on that example, the subnets started at…
.0.0, .4.0, .8.0, .12.0, .16.0 and so on

i’m interested in a.b.c.d., i try to get that in between 2 subnets.

in the example it was xx.xx.14.15, i’m interested in that 14 (because my subnet example was incomplete in the 3rd bit: 252) so i start comparing, i see that it’s bigger than 12, lesser than 16, that means that the lesser value is my answer (simple logic, it could not start at the bigger value). answer: 12.0

LOL
Only did it to explain

@neilg
the problem is not typing it down, not my site, not my rules.
the thing is that you didnt give that up and you will tend to do that on the exam too. on my paper i only wrote some output from a show cdp nei command. time is of the essence.

Xallax
I did it to explain to Osiris, dont do it for myself

I drew up a little table for myself, no more writing except for the answer

Come test day I will quickly scribble down my table before the test starts, write once use many times

Anyone got hired by just being a CCENT? Seems like the industry standard should be CCNA.

@jeff
depends on what the employer wants… if they’re interested in someone that knows how to crimp a cable then you’re hired, if they want someone that knows every single piece and option of a cisco device then they’re looking for CCIEs…
depends on the employer

Great site. The examples are good for practising the knowledge you already have but requires more thorough revision. 1 thing I do struggle on is the path a packet takes over a LAN and WAN in regards to the MAC/IP addresses each device uses.. I have 3 days to get this right in my head as my exam is Tuesday morning!

@Xallax:
216.21.5.0/24 – 5 nets
5 > 4, 5 < 8, 8 = 2^3. 2^3 is 224
increment 256-224 = 32
nets are x.x.x.0, x.x.x.32, so on…

This example further up is incorrect…

To get 5 networks you would require using 4 bits (1 2 4 *8*) 2^4 = 16 which in turn creates a subnet mask of 240. The increment is 16.

uhm… no…
please think again 🙂
if you had blocks of 16 then you’d have 256/16=16 subnets…

Rick
On the Power of table you start with 2^0, then 1, 2, 3

U use the little number above the 2^ , dont count the blocks
It confused me for a day or 2 aswell

Therefore u are wrong in your explanation

Ah yea sorry, was confused then. You’re right. Ignore me 🙂

Rick
IP = source and destination address, “doesnt change” except when u use NAT
Works at Network Layer (packets)

MAC = changes while frames travel on a WAN, a MAC is a “LAN address”
So this changes as the bits travel
Works at DataLink Layer

Heres an example
U want to travel from CITY A to Z by car (source and destination IP)
That never changes, its where you coming from and where u are going to

As you trravel to your destination by road you will get smaller towns inbetween call them T1 – 3, this will change all the time as you travel, think of that as your MAC

So you Start OFF
Source A Dest Z (IP)
Source A Dest T1 (MAC)

U go through town 1
Source A Dest Z (IP)
Source T1 Dest T2 (MAC)

And so on

Does it make sense ?

@rick
please read above, we had a little chat regarding subnetting. hope it will help

Quick question. In the CBT vids he states the 1st and last addresses in a subnetwork is called the network and broadcast address. What do Cisco call these in the exams?

@rick
they’re called the same. those are IP addresses that you can not assign to hosts/interfaces.

@neilg
nice analogy

@neilG
Yes it does make sense and I understand the theory. What throws me off sometimes is for example what would certain routers/hosts have as dest/source on the other side of the LAN etc. I know the IP never changes so that’s cool, it’s the MAC side of things.. it’s hard to explain in writing without images…

Thanks for the help though 🙂

@xallax
Yes it makes sense to me now, I was miscalculating the 2^x, all good now 🙂

Okay like this

Say u have 1 Router with 2 Ethernet Interfaces

You have
Host A (Mac addr A111
RouterX int A (Mac Addr AX22
RouterX int B (Mac Addr BX33
HostB (Mac addr B444

By looking at the IP host A sees Host B is on a different network, so it cant get the MAC addrress, then it checks its own routing table to see where data must be sent if the destination is “unknown”, its its def gw

It ARPs for the DeF GW Mac
Source MAC Host A
Dest MaC RouterX int A

Router X IntA now checks its Routing table
Source MAC RouterX intA
Dest MAC RouterX intB

RouterX int B now checks the headers and sees Ahhhh, this IP is on my networks and sends out a ARP (broadcast) for the MAC Addr for Host B, Host B replies with its MAC addr

Then
Source MAC RouterX int B
Dest MAC Host B

I got my CCNET certification today. I wanna know if I have to do something in order to get any card or digital certificate. I haven’t checked the web page yet. I appreciate your help in this side. Look forward to ICND 2 soon.
COncepts, and do labs in packet tracer, subnetting is important. The Xallax’s labs are good.
I got 1K/1K.

I used ElmerFlud.vce

@nerroazurro
congratulations and thanks for the share all around the site.
go to cisco’s site, log in and opt in to get the free hard print certificate, congratulations letter and the plastic card.

you got 1k, you earned your tittle!
will see you on the icnd2 pages from now on.

Passed yesterday with a 950 used CBT Nuggets + this web site + the newest testking exam and the Newest actualexams off of exam collection website I would say I had seen about 85% of the questions which I had on the exam before and even some of the numbers in the subnetting were the same. Also there were not as many subnetting questions as I was expecting

The icnd1 exams on exam collection may not have been updated for a while but they are still very valid

Thanks 9tut

anyone here actually had home labs?

@jeff
that would be kinda expensive, but i guess there are people that can afford having a home lab

@Jeff: You should use GNS3 to simulate routers. It is enough to practice CCNA.

I only used PT for ICND1. Do I need GNS3 for ICND2 or should PT be enough?

Use PT to get a feel for Network Setups, Routers, Switches, Servers etc
Use GNS3 for the feel of working on a real router

I use both

@Xallax, $5.00 for your material? I get drag/drops, Q&A?

yes sir. questions, drag and drops, links to video, forums…
everything you need 🙂

My exam is tomorrow. I’ll give my experience and whether I passed or failed.. wish me luck!

@rick
good luck!

@rick
Best of luck man

@Rick, Kick ass dude..

@xallax: Thx. I am gonna start studying for CCNA II the next month.

@ xallax. I am on the Cisco’s web page. Do I have to buy my certificates and card? There is no free card or certificates?

I passed friday with 899. I got some different drag and drop questions from this website and an ospf question. If you are going to take it, make sure you put forth the effort learn and really understand the material. Good luck to everyone. On to icnd2!!!

@curt i got it for free…

sorry, it was for nerroazurro 🙂

I passed today and got 899 as well. Was easier than I thought but know the material! Had
drag and drops: DHCP DORA & Db/Email/Collaboration, Sims: Security & Implementation 1.
I used the Official ICND1 Book, CBT Nuggets, CCENT Exam Cram and the latest actualtest vce off examcollection – not too mention this site. The vce had a majority of the questions on the exam. Onto ICND2!

I see postings here about people saying ” know your telnet backwards and forwards”.. Are they referring to know the definitions or are there any telnet sims that I should know about? I checked all sims and I do not see any telnet sims on here so, maybe they are referring to telnet definitions…

@bigd
what’s there to know about telnet?

it sends data without encryption (clear text)
both sender and receiver must have telnet enabled
it works on port 23 by default (server is operating on this port)
it’s used to operate a device remotely by emulating the console
on cisco devices, telnet works under the “vty” lines

that’s about it…

and…
it’s enabled by default
it requires password by default (“login” is set)

That’s what I thought, but I thought maybe I was missing something else. I am taking my exam next week so I am just covering all the bases. As always, Mr Xallax, thank you

if you want to be 99.5% sure (there must be room for error, always) then go practice it in packettracer
this is a good lab too. shouldn’t take you more than 5 minutes

1 pc:
ip 1.1.1.1
subnet 255.0.0.0
default gateway: 1.1.1.3

1 switch with ip set on vlan1:
enable
configure terminal
interface vlan1
no shutdown
ip address 1.1.1.2 255.0.0.0
exit
ip default-gateway 1.1.1.3
line vty 0
password 1
login
do write

1 router with ip set on the lan interface
enable
configure terminal
interface fa0/0
no shutdown
ip address 1.1.1.3 255.0.0.0
line vty 0
password 1
login
do write

now try telnetting from:
pc to switch
pc to router
switch to router

@Mr. Xallax, will do, muchas gracias.

stop calling me “Mr.”, please.
it’s my pleasure to try and help 🙂

Sorry, just being thankful. Didn’t mean to ruin your day.

you haven’t, don’t worry 🙂
thanks

Hey Bigd, seems like you have prepared well for ICND1. You should be fine.

Theres a bit more to “telnet”

Username and password (with login local cmd)
Vty password
Password encryption
Privilege level (1 or 15)
Session time out
No login command (no auth required)
Changing from telnet to SSH (transport input ssh)
How many VTY ports

Like Xallax said, use Packet Tracer and practice
Dont be scared to look at some of the command options aswell

@neilg
and terminal monitor! 😀

@Jeff, what makes you say that?

@Jeff, you know, you study, prepare and you study some more and you feel like you missed something. Then, in the middle of the exam you get a question that stumps you. I guess you can’t get everything.

If you really studied your material, you have to be confident to say that you are already CCENT. Passing the exam just makes it official (I got this off the Chris Bryant site). I mean I self-studied and still did well because I worked hard for it and earned the CCENT title. It took me about 40 days of 4-5 hours of studying. When I signed up to actually take the exam, I know I am going to pass it. You have to think positive because there will always be a question that would stump you. Answer it then move on. This is the entry level certification so it shouldn’t be too hard.

Passed yesterday with a score of 875 🙂

Couple of questions/sims were from here but the majority were not so you have to know your stuff!

Back to studying now for ICND2, see you on the other section of this site!

@Rick
Hey congrats there man on passing and with a good score. Just one question of the dumps you used how much would you say was there and how much was new?
