This post is intended to be a one stop aggregate of content related to the CCNA R&S, new users are encouraged to look through this post before asking these common post topics. Because I'm lazy I'll be copy and pasting relevant sections from other posts as needed :)
No, at best you'll get basic information but you'll be missing topics, reading about topics you don't need to, and could generally not learn a topic well enough. It isn't worth trying to save money since failing the exam is much more expensive than some new books.
Saying that some video courses are still worth while, CBT nuggets for example has plenty of CCNA related series such as their CCNA packet capture course that is still good info though out of date.
You can occasionally save some $$$ by buying a discount voucher, a discount voucher is a voucher that is expiring sooner than a ordinary voucher, the less time left the more it is discounted. For example a CCNA voucher with 3 days left might get 50% off.
I have used these sites before and they work well.
CCNA 2.0 is being retired on the following dates:
100-101 ICND1 Last day to test August 20, 2016
200-101 ICND2 Last day to test September 24, 2016
200-120 CCNA Last day to test August 20, 2016
A common misconception is that ICND1 is a prerequisite for the CCNA, it is not. Rather the ICND1 earns the CCENT certification and the CCENT is the prerequisite for the CCNA. This distinction means that you can write the 3.0 ICND2 exam even if you have passed the ICND1 2.0 exam.
100-105 - ICND1 3.0
Here is a summary of the changes in the new version:
RIP is now the sole routing protocol in this exam.
IPv6 Dual Stack was removed in favour of transition techologies
CEF has been removed from the exam.
High level knowledge of Firewalls, Access Points, and Wireless Controllers
Awareness of Collapsed Core architecture
Configure and verify IPv6 SLAAC
IPv6 Anycast addresses
Knowledge of LLDP
Troubleshooting DNS and DHCP related connectivity issues
200-105 - ICND2 3.0
200-125 - CCNAX 3.0
All in all some pretty fair additions and only a couple questionable removals.
The short answer is....no, probably not.
Generally speaking the composite is only for the experienced network professionals who are used to certification exams. It is really meant for convenient switching to the R&S track from say Juniper. Why not take it? It's just considered to be a much more difficult exam because:
It doubles the number of topics you can be tested on, this makes it so you must have mastered everything in the CCNA since it is fair game. This also makes repeat attempts harder since the question pool is large enough that if you do badly on say IP Services, you might instead get a security focus the next time. You have a smaller margin of error: with ICND1 and 2 you can get say...10 questions wrong to pass with the minimum score so you can get 20 questions wrong and still be a CCNA. With the composite you can only get 10 wrong before failing
There is less padding questions, icnd1 may also you 10 subnetting questions but the composite may just ask a couple and move on the next topic. This makes things harder since your more likely to hit a hard question rather than get a few easier ones.
Cisco assumes your a network professional so they may hit harder than with the other exams. Based on my own observations from watching this sub and talking to people, I would say a junior has about a 90% fail rate for the composite and it typically takes them about 3 tries to pass it. Incidentally they also tend to be bitter with Cisco after paying for so many failed exams. Long story short, it isn't worth it, I should also point out that you get the same CCNA no matter what path you take. The only difference is that with the two exam method you get the CCENT as well, which means you can get up to two kitty gifs!
Books by Odom and Lammle remain our recommendations for this CCNA version, you should read both to get both perspectives on topics. Generally Odom is considered to be more dry and technical and Lammle is more readable and approachable.
There are two main options for a home lab - physical and virtual. You can also mix and match as needed.
Because of the new version it is recommended to try to use IOS 15 in all your physical gear so you can utilize the modern features that IOS brings to the table. The router models don't matter all that much since features at the CCNA and CCNP level are mostly the same, you also don't need to worry about serial modules nearly as much because serial is a very small topic now.
Model numbers matter with switches though, you should aim to get 3 or 4 Cisco 3560 switches so your lab will last you well past your CCNA R&S studies, though you can pick up a some L2 Cisco 2960 switches if need be.
For virtual you have 3 main options
PT 7.0 is out now and can be gotten for free from Cisco.
Here is a blog post I wrote about setting it up end to end:
Here is the post I did about VIRL:
Remember there is no back button so always read the question until you fully understand what it is asking you and you know what technology it is testing you on before answering.
If you can't think of an answer within a minute consider picking the best answer and moving on. You are unlikely to correctly figure out the question after thinking about it for another minute and will likely talk yourself into a wrong answer. You don't have a ton of time in the exam!
For people with a bit more IT experience, remember the context and level of the exam. There are many solutions to problems in the real world and at the end of the day the CCNA doesn't get too deep into topics. Keep the exam topics in mind when answering a question...for example if Cisco asks what device would run BGP? Then the answer would be a router even though most devices can support BGP these days from hosts to servers to firewalls etc. The reason why is the CCNA v3.0 only teaches about basic eBGP on a router so Cisco isn't going to expect you to know that Windows Server can do BGP.
People also have a lot of issues getting used to the concept of the best answer. Like the BGP scenario above you have to keep the context of the question in mind, a router can indeed use a switch module to act like a switch and a L3 switch can act like a router etc but if they ask what device is best for switching then it will be a switch.
The "Cisco Answer" is something that keeps popping up over and over, and in my opinion is drastically overblown and misunderstood in most cases. Basically it is the claim that Cisco wants you to answer the question their way as opposed to the industry correct answer. Generally this seems to be feed from the pitfalls I mentioned above:
An example of an old Cisco answer was back when other vendors first started supporting CDP and if you were asked if CDP only ran on Cisco you had to decide if Cisco was expecting you to know that polycom phones could do CDP. But generally those types of questions are gone in the R&S track at least (I'm told the wireless track needs more time in the oven)
The other place it comes from is when you are multi vendor and/or have a higher knowledge/experience level then the exam your writing. A simple example might be if they asked you how many link state routing protocols are supported by Cisco, a CCNA will probably say 1, whereas a more advanced candidate may answer 2. But considering CCNA doesn't mention IS-IS then 1 would be the CCNA correct answer. The trick is you have to keep your exam level in mind as your writing it.
Finally there is the obvious actual Cisco answer where if they asked you what OSPF's Administrative Distances is? Now on Cisco it is 110/110/110, on Juniper it is 10/150, and on HPE it is 10/150/150. So in this case they are looking for the Cisco right answer but that only really can affect you if you are multi-vendor.
Sim's generally have support for the
? but it can be limited if Cisco decides to remove them to make sure you know how to do a task or if they simply just don't fully implement them since the sim is just a flash animation they have to program. It is also worth noting that even if Cisco does give you full functionality, you would still need to know the full commands since Cisco can just straight up ask you syntax questions.
The Boson practice tests are highly regarded and tend to be of similar difficulty or more difficult than the actual exam.
I'll try to keep this updated as they pop up but here is the current posts that are cover the new topics
With the exam cutoff looming there have been a ton of questions lately about if people should take the composite exam. The short answer is....no, probably not.
Generally speaking the composite is only for the experienced network professionals who are used to certification exams. It is really meant for convenient switching to the R&S track from say Juniper.
Why not take it? It's just considered to be a much more difficult exam because:

I feel like I'm taking way too long hammering in the information. Decided to just take a chance on it. I studied for about 4 months.
I took the Boson exams over the past month.
Exam 1: 672
Exam 2: 831
Exam 3: 762
I'll save exam 4 in case I don't pass my first attempt on the real exam. Wish me luck!
I'm super happy I passed and didn't expect to score so high. Onto the ICND2!
-Boson Exams (This helped a ton)
I found it difficult applying for networking jobs when I had little to no experience after I earned the CCNA(R&S).
Helpdesk and IT support always seemed to be more entry level and easier to apply for.
As the title says, I'm interested if anyone has read both and that your thoughts are. I have both, bought Lammle and was given OCG by my school. I'm about to take ICND1 tomorrow and I used CBTnuggets and the OCG with boson sim/exam prep, but I feel like I'm missing some info. If I pass I'll move right on to icnd2, so lmk if you think I should change books!! TiA!
this is my first post on Reddit so I hope I won't mess this up.
I'm studying for the 200-125 on the Cisco NetAcademy and there is one thing I can't quite understand.
In the example there is a web server in the inside network with local IP 192.168.10.254, listening on the port 80.
The global IP of the web server is 22.214.171.124
On the external router of the web server the following port forwarding command is implemented
So far I understood that port forwarding must be used because by default our router won't accept external connection that were not originally started by us.
I understand why I need to translate the IP, I don't get why I have to translate the port too if I need the HTML service (80) and the server is listening already to 80.
Can't the Client requesting the website just use the normal URl without the translation from 8080 to 80?
I hope I managed to explain myself in a decent way :)
Please ELI5 :D
Thanks for helping a network noob trying to understand stuff!
Anyone know of a respectable training center or boot camp in the Chicago area? Not looking for a certmill.
Gotta renew for work VERY soon, don't have the time to self study at the moment and would prefer a class room environment.
Basically, my CCNA R&S expires at the start of next month. I'm taking CCNA security for my school (WGU) but I'm not ready to take it before my R&S expires. I have to take if after the fact. If I pass, I'll pass but not become certified. If I take my CCNA R&S exam later on, will I become certified in R&S and Sec or just R&S? Thanks all.
I've been working on a series of 60 second videos related to subnetting recently to try and demystify it a little. This week's video pertains to subnet masks and how they relate to subnets IP addresses. I hope this clears some things up for some of you. If you enjoy the video, please consider subscribing as it helps me a lot.
If you have any suggestions, I'm happy to hear them. I've been using some of the great feedback I've received to improve my videos each week. That being said, the most frequent criticism that I have is that I am speaking too fast. At the same time, I get a lot of praise for having the videos as fast as they are and the point of the videos is to cover the topic in 60 seconds or less. I'm looking into ways to make the videos more understandable so that more people enjoy the videos, yet fast enough that the topic is covered with enough detail that the video is useful. For now though, the speed of the videos will remain around what is normally a 2x pace.
I have purchased both Lammle's and Odom's CCENT books. I also was given access to the CBT nuggets which I've used before for Network+ to great success. My question is, how should I integrate the books into the training?
Should I go through all the videos and lab with the videos and just read the books after I finish the video series?
Or should I watch a couple videos, read the books sections on the same topics, and then do the labs?
If anyone has any recommendations how to incorporate the books with the video training, I would love some advice. I am a pretty good reader and I enjoy both Lammle's and Odom's style and how they vary. Time is not really of the essence, I just want to truly learn as much as I can. The exam is more of an afterthought.
I had a student ask me for a link of every article on my blog that covers CCNA topics. I put together this list, and thought I would pass it on to /r/ccna as well.
This doesn't cover the entire CCNA curriculum, but I earnestly believe that what it does cover, it does so in the best way possible. I am, of course, open to hear any feedback to the contrary =)
Disclaimer: I wrote these articles, and I earnestly believe they will help the readers of this subreddit. These are all 100% free. There is no ads on the site. I make no revenue from you reading them. There is no mandatory e-mail sign up or soft paywall.
Edit: Whoa, this blew up. Thank you for the kind words, everyone, I'm really happy you're getting a lot out of the articles. Truly. Also, thank you for the gold, kind stranger =) Was not expecting that at all!.
Edit2: Just because I'm a feedback junky... I would love to hear what some of you think about the articles themselves... which have been your favorites, why? Which left more questions than answers? Which need more details, which needs less? Anything you want to provide =)
I recently got my CCNA but I'm having trouble finding a job where I can put it to use. I am subscribed to job searches in my desired city (Austin, TX) and apply to all of the ones that I think would be a good fit. I haven't heard anything back except for a few responses along the lines of, "Nice resume, but we're going with another candidate."
For a little backstory, I've been a System Administrator for three years now. Along the way I was exposed to myriad systems, OSes, networks, and configs. I have a big job with a ton of responsibility in a place that absolutely requires 100% up time and I mostly man the job alone during my current shift. I have found that any time I get to do networking stuff, those are the best days. That's what lead me to pursue my CCNA and that's that path I see my career going in.
However, as I outlined above, I don't feel like I'm garnering the interest that I should. In my cover letter I outline that I am constantly praised by management (my boss calls me a Rockstar, my colleagues say I'm one of our strongest, most creative problem solvers) and have excelled in my current position.
I don't really want to stay with my current company or in my current area (SoCal) because I don't enjoy the environment that I'm in. I know that if a new Network Engineer (the job I want) position were to become available here, it would be mine but I'm also worried about getting "stuck" here for even longer while I rake in more experience.
Thanks in advance for any help!
Hi all, absolute newb here. I saw in this post that IOS15 and PoE don't play nicely together. Can someone confirm/elaborate? What's the preference for CCNA study?
My current lab setup (purchased, waiting on delivery) is:
3 x 2821 IOS 15 routers
2 x C3550 PoE L3 switches
1 x unknown 3rd switch (it disappeared in delivery, negotiating replacement...)
Have I shagged myself already by purchasing IOS 15 routers and PoE switches?
Sorry if it's not directly CCNA related but I'm not sure where else to ask. I tried r/GNS3 but no luck so I thought I'd try a larger audience.
I have CiscoIOSv15.6(2)T routers and when I try to turn on the nodes I get this error message.

I've tried to setup a network bridge though I'm not sure if it's needed but I had an issue with that too. I used my wireless interface as the bridge port but DHCP never worked (never picked up an IP) when I'd bring the bridge interface up and with a manual IP I would lose internet connectivity once I brought up the bridge interface. Again not sure it's even needed but I found it in some KVM VM guides.
I just had a quick question on the topic of study guides. I'm looking into buying the Odom book for 100-105, but have my doubts on whether I should. Like I mentioned in the title, I took a course for networking which covered everything for both ICND1 and ICND2 (it was about a year and a half), the teacher used Netacad as a source for us to study by so I have all my notes from when I was at school. Should I still buy a study guide like Odom, even though I have all my notes from school?
922/1000, minimum passing score of 810
Gotta say I was worried going into it because I was reading things on here and other places like 'don't go for the composite unless you have 2 years/5 years/however many years of experience working with Cisco equipment'.
However, despite having 0 experience networking or the IT field in general, I studied for just 8 weeks and passed comfortably. I was super relieved to see that score when I pressed finish!
Neil Anderson's CCNA course/labs
Alphaprep practice quizzes/exams
Read a couple chapters from the official cert guides when I wasn't sure of something.
Although taking the two exam approach is still the safer option: for those going for the single exam, just know it is possible without prior experience. Learn the material, and go for it!
I know this is a CCNA sub-reddit, but if you know any co-workers who want to earn an entry-level Microsoft Technical Associate (MTA) certification, please feel free to share my course.
So I'm reading through ICND2 and a lot of questions have popped into my head in one particular section(Ch. 6 Miscellaneous LAN Topics in Odom OCG). I haven't really found an answer to these questions so far and I just want to make sure I understand these topics correctly.
I read that AAA authentication starts from the supplicant who initiates 802.1x authentication to a switch using EAP, but then after it uses RADIUS or TACACS+ encapsulated in an IP packet. My understanding of layer 2 switches is that they operate strictly on a layer 2 level by forwarding/filtering frames. It sounds to me like a switch that uses RADIUS or TACACS+ must need some level of layer 3(IP) functionality in order to communicate with the AAA server. Is this something that typical layer 2 devices can do, or is this functionality only available with layer 3 switches and routers?
And on that note, I imagine that even assigning a simple IP to VLAN 1 on a switch for management purposes must require some layer of IP functionality? If you can ping the switch, it must be able to encapsulate the ICMP echo request and then re-encapsulate a new packet for an ICMP echo reply. With that, I feel like I must conclude that just about every layer 2 switch must be able to encapsulate/deencapsulate layer 3 packets, but the difference is that they don't keep a routing table for forwarding/filtering purposes? Is my understanding correct?
Lastly, is a AAA server typically the same server that Active Directory is installed on? Can AD be used with Cisco switches/routers? I've used AD quite a bit and understand domain controllers, trees, trusts, etc and it just sounds to me like an AAA server has basically the exact same function. Is an AD domain controller just a more specific example of a AAA server?
WOOOO - I Passed!!!!
I feel so happy, because last year, I attempted the ICND1, but I failed miserably by 6 points. That day, I went in thinking I knew everything, but got out with less confidence.
Today I went in, and was a little nervous at first, mainly because (1) I forgot to reschedule my exam for the 5th time because (2) I sort of felt that I was not ready. And after months of studying, it all came down to this.
GNS3 n00b here. I have downloaded GNS3 but don't know where to start. How do I download the files to actually be able to use this? Where do I get practice labs and such? Any resources you could share would be great. Thank you, this community is fantastic.
So, if any of you have any input, it would be great.
Just wondering as a newbie, besides using it for lab purposes practicing show commands and configuration, what else can buying 3 switches, 2 routers, and a firewall do for me?
probably the 2811, 3560, etc.
Is there a practical use for these instruments at my home, or would it just be for lab practice?
The last time I sat for ICND2 was right before the exam update. Is it just me or have Cisco's questions become extremely vague? I mean the simulator stuff all makes perfect sense. But a diagram with no notation and a one sentence question about trouble shooting connectivity? Gimme a break. I was pretty shocked that I passed. It really felt like a roll of the dice. I am network engineer by day, but this exam didn't in anyway feel like an appropriate measure of my knowledge. Oh well.
So I’m a little ahead of my self here but I want to buy the lab I need to pass CCENT/CCNA and then figure out where I want to go beyond that.
I’ve read a lot about what to buy, but I’m confused on what cables I may need (serial, console, etc). I was reading for the new test we don’t need serial cables? If it’s needed, I’ll also need the rollover usb cable.
As far as Ethernet and cat v, I can make my own straight and crossover cables. So no issues there and power cables I have.
So will these six devices get me started, and what “console” or serial cables should I buy? Do I need some modules?
Is it safe to just buy these and then figure out what cables I need next? I know one comes with a “console” cable.
I’m just about to finish part one of Odom’s book. So a little ahead, but I want to have the stuff in advance and plan to continue after CCNA.
I also have more than enough different kinds of hosts to connect. Most of them have newer windows though, is that bad? I also have an old 2007 windows server I could play with if it was worth it, but again getting ahead of my self. I have some raspberry pi’s and ardinuo, maybe I can find a way to incorporate them. I set the pi up as an Apache server one time and was able to access it through my home network. There’s Ethernet ports in every room of the house I’m going to lab in, so that’s a bonus too.
My cart is $375 right now for these 6 devices. Seems about right?
