Hi all,

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 :)

Can I use older versions of the study material?

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for example has plenty of CCNA related series such as their CCNA packet capture course that is still good info though out of date.


Discount Exams

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.

www.itexamvouchers.com or www.getcertified4less.com

The Exam Change

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.

Exam topics

100-105 - ICND1 3.0

200-125 - CCNAX 3.0

Composite 3.0 Exam topics

All in all some pretty fair additions and only a couple questionable removals.

Should you 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:

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!

Reading List

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.

Home Lab

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

  • Packet Tracer - a mostly functional emulation tool that meets most of the CCNA requirements, it requires very little resources or technical knowledge but only supports just enough IOS features for you to pass the CCNA.

PT 7.0 is out now and can be gotten for free from Cisco.

  • GNS3 - a functional solution that runs real IOS images, the downside is you need to get your hand on IOS images. It also doesn't have native support for most L2 features.

Here is a blog post I wrote about setting it up end to end:

Mastering GNS3

  • VIRL - this is the most resource heavy option but its benefit is that Cisco provides IOS images to you.

Here is the post I did about VIRL:

Mastering VIRL

Exam Tips

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.

The Best Answer

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

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.

Question Marks and Tab

Sim's generally have support for the tab and ? 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.

Practice Tests

The Boson practice tests are highly regarded and tend to be of similar difficulty or more difficult than the actual exam.

New topic posts

I'll try to keep this updated as they pop up but here is the current posts that are cover the new topics

What is Metro Ethernet

What is MPLS as a WAN Service

What is BGP?

I was super demoralized after failing the ICND2, it was the first cert exam I've failed. All I could think about was the wasted $160 I paid to take the proctored exam. Anyway, it all worked out in the end, it just cost me more than I wanted it to.

I used the TestOut Labsim Routing and Switching Pro course. I had to buy it for a university class anyway, and it covers almost all of the material except the APIC traceroute and SPAN troubleshooting and a few other little things. The videos, demos, labs, info sheets, and loads of practice questions were all good and I would recommend it if you're looking for a one stop shop for your studies. You just need to supplement that studying with the newest stuff that isn't covered in the course, but you can find those easily in the exam objectives.

/32 increments by 2.

0-1: 0 is the network id and 1 is broadcast

2-3: 2 is the network id and 3 is broadcast

so theres no usable IP in its range. What is the use of having a /32 network?

Try no. 2, just want to thank this sub for the encouragement to keep on! Now, on to ICND 2...

Used INE videos/rack rentals, Boson Exams, the practicalnetworking.net site was helpful with getting started again, after a hiatus of a few months, and Lammle's book. Of course I had the old version of the book and didn't realize it until I read the whole damn thing!

I started my IT apprenticeship when I was 15years old, during my apprenticeship I got to experience a lot of different IT departments and the Network team was by far the most interesting one. So for my last year I worked there and learned a lot and since a position opened up as a network specialist around the time I'd be finished my mentor told me that they'd hire me and give me a better salary if I passed the CCNA R&S. So around 4 months ago I started studying for the exam and after 2 months I had my first attempt, as expected I failed with a score of 750/810.

I wasn't discouraged by that and started reading on those topics I had problem with and did a lot of Switching labs since that was my weak point. Going into my second attempt last week I felt a lot more comfortable with all the material and I actually passed! My score isn't really impressive (839/810) and I was expecting to be a little bit better but I'm glad I was able to achieve that.

I'm not quite sure where I'm going with all this now but I'm glad I can get a lot of work experience now.

I've also got a question, in my first attempt I had less questions but 2 more exam topics, Infrastructure Security and Infrastructure Management were missing on my second try. Could anyone explain this?

EDIT: *"I wasn't discouraged" and not "I wasn't encouraged" :D was a typo

I thought i failed this exam because i skipped a whole sim question by accident...

Anyways, break down is here:
Network Fundamentals - 92%
LAN Switching Fundamentals - 81%
Routing Fundamentals - 100%
Infrastructure Services - 33%
Infrastructure Maintenance - 50%

I used the following:
INE Videos and Labs
Boson exSim
On-job experience
These Packet Tracer labs found in the comments - https://learningnetwork.cisco.com/thread/4933

I didn’t use the OCG as i'm not a big fan of reading and it's not really the way i learn personally. I started my job about 5 months ago and i started actually studying about 2 months ago.

Will be starting my studying on ICND2 come Monday!

OK, so in this lammlie packettracer lab it says to use a subnet mask that will allow 4096 subnets with 4094 hosts per subnet with the 10.0.0.0 network. I completely understand that I need 12 1's to do this making a 255.255.240.0 subnet (11111111.11111111.11110000.00000000). Where I'm confused is where all of these subnets are coming from? The way I understand they're laid out is as follows:

10.0.0.0 - .15.255
10.0.16.0 - .32.255
10.0.32.0 - 63.255
10.0.64.0 - 79.255
10.0.80.0
10.0.96.0
10.0.112.0
10.0.128.0
10.0.144.0
10.0.160.0

10.0.172.0

10.0.188.0

10.0.204.0

10.0.220.0

10.0.236.0

10.0.252.0

I understand how to subnet these out, but what is confusing me is the 4096 subnets. How is that making that many subnets? I only see 16 subnets here, what am I missing!?

I know to use the powers of 2 to get there, but something isn't clicking.

Ran into this and tried to lab it in PT but could not replicate. I don't have a router handy to try it on until tomorrow. So this is the gist of the issue:

Boson ExSim 200-105 H1

Q: RouterA is unable to communicate with RouterB?

Running config on RouterB shows this:

interface Serial0

ip address 10.1.1.2 255.255.255.240

no ip directed-broadcast

ppp authentication chap

Correct answer is: Router B is using default encapsulation.

I know HDLC does not support authentication. I know in PT you cannot place authentication on an HDLC serial (PT tells you no). Just to test I tried swapping to PPP, entering ppp auth chap, and swapping back to HDLC. Still does not show in running config.

In the Boson ex-sim it will let you place authentication on an HDLC serial(it does not say no). Also you can swap to PPP, enter ppp auth chap, swap back to HDLC and it will still show in running config.

I'm just guessing here but I should never see a running config that looks like the one from the ExSim?

I attempted the ICND1 exam about 2 years ago and I remember the simulation questions really overwhelming me (it was my first cert test) and I was wondering if you guys have any advice on how to tackle them for my next attempt in two (2) weeks.

Passed my SECFND today. Was very shocked to see I only got 854/1000 but I rushed through it taking only 17 minutes out of the allotted 80 minutes hahaha.

Keys to my success: -Cyber Ops online scholarship material -Udemy practice tests (did these until I was getting over 90% on all them) -Working out/keeping physically fit (kept me mentally engaged when studying)

I have no idea how I passed that. I thought after the first 10 questions I had failed, and kept going to "see what else I don't know". Got to the end and passed, which seems to be a recurring theme here - Cisco must be running numbers on heart attacks in their exams

I mainly used Chris Bryant's udemy courses, Ross B on pluralsight, Rene M from Network Lessons and the books. I really liked Network Lessons. Its a bit pricey, but I liked the ability to copy it into an evernote note and read it on my phone when work is quiet. Chris Bryant also has a strangely soothing voice - fell asleep listening to a few of his videos late at night.

I'm really interested in the sdn stuff, so I'm going to "borrow" a beefy server from work and see If I can get Apic-em going on my lab equipment.

Next step is to do some Mikrotik training for work, then get into the ccnp with a guy from work. Going to go home and have some rum while playing Civ 5.

Hey guys, I hate to be that guy, but I'm broke as hell and unable to renew my CBTNuggets subscription to do those awesome labs I used for ICND1. Anyone have any good recommendations for ICND2 labs? I've tried to just make stuff up, but it really isn't working for me. I appreciate the help.

Hi! I'd like some help with my nat config.

My host is using IP address 10.0.0.50/24. It has the default gateway set. I can ping from the router to the Internet but not from my host, a tracert shows that the traffic stops at my router.

Can you guys see what I messed up?

ip nat pool nat1 10.0.0.1 10.0.0.254 netmask 255.255.255.0

I'm starting to get into studying for the ccent, in my spare time I've just been browsing facebook marketplace for bits and pieces for a home lab. Today I came across a complete kit that somebody is no longer using. The kit contains :

  • 3 Catalyst 2950 switches
  • 1 Cisco 2800 router
  • 2 Cisco 2651 XM routers
  • Rack for the above

From what I've read 2950's are no longer desirable but I haven't really seen why. I'm assuming age, support, features, and I don't think you can go up to 15 on them. As for the 2 Cisco 2651 XM routers, I think those were also old and can't go up to 15. The 2800 seems to be the best of the group while still supporting ios 15. This whole kit is selling for $200 and I'm struggling to figure out if it's worth it or not for use past ccent or if I should get less dated hardware.

For EUI-64, don't you just split the MAC and add FF:FE into the middle? If so, didn't I choose the correct answer? Is there an error on this practice test?

So fresh off my ICND1 I'm now working my way through the ICND2 OCG. I've just started looking at STP and something isn't clear to me.

Here is the topology STP topology

From the book. "The root switch sends Hellos, with a listed root cost of 0. The idea is that the root’s cost to reach itself is 0.

Next, look on the left of the figure. SW3 takes the received cost (0) from the Hello sent by SW1, and adds the interface cost (5) of the interface on which that Hello was received. SW3 calculates that the cost to reach the root switch, out that port (G0/1), is 5.

On the right side, SW2 has realized its best cost to reach the root is cost 4. So, when SW2 forwards the Hello toward SW3, SW2 lists a root cost 4. SW3’s STP port cost on port G0/2 is 4, so SW3 determines a total cost to reach root out its G0/2 port of 8.


A few questions:

Why does SW2 list a root cost of 4 when forwarding a hello to SW3 on Gi0/1? Does SW2 not need to calculate the root cost out that port which would be 0 + the interface cost of Gi0/1. This interface cost isn't listed in the diagram so is it inferred to be 4?

Also why does SW3 not list a root cost of 4 out of Gi0/2? Is this because it's received the hello forwarded by Sw2 before SW3 has received the hello from sw1 and had a chance to forward it?

CORE BREAKDOWN

Network Fundamentals : 40%

LAN Switching Fundamentals : 73%

Routing Fundamentals : 88%

WAN Technologies : 57%

Infrastructure Services : 71%

Infrastructure Security : 63%

Infrastructure Management : 71%

First of all HOW DID I PASS OMG!!!!!!!

Sources that i used were the lammle book and other free practice testing websites

About the test i was not prepared about the entire time management. I started to panic at my first simlet taking about 25 mins. I got the hang of the format as i went on. I also want to add THIS WAS MY FIRST ATTEMPT IN ANY CERTIFICATION!!! I only have 1 year of IT experience from going to university. I found this subreddit a bit later than i should have but thank you for all of your tips. If you have any questions feel free to ask

EDIT: Also i would like to add is what do i do now. The sheet said i have to wait 10 days. Is the passing grade final or should i panic?

Hello!

I'm building my own LAN using Cisco routers and switches. I'm studying (slowly) for the CCENT and CCNA certifications.

What are your "must do" configurations for every switch and router?

I'm not looking for everything I need to know for the exams, just wondering what you guys think should always be set up in a router and switch.

Passed 210-255 SECOPS yesterday and received an email this morning containing notification my CSCO profile was updated with my Cert! Excited!

I got vouchers for the program and studied the online resource, the Official Study Guide, the 2 main NIST PDFs containing CSIRT guidelines.

Not sure what to do next. I initially planned to get CCNA:R&S certified so I may do that. Then climb that track.. since there inst a CCNP: Cyber Ops. Right now I wanna find a job in Networking/Security. I enjoy the general sysadmin position I have now, but want to focus on those things.

Anywho, I just wanted to share! Thanks for reading. Have a great day!

Hey All! Quick question, going through the boson, setup of intervlan routing between vlan 1, 2 and 3. When applying config to the trunk port of the router (fa0/1), is it correct to add vlan 1 router address to the physical fa/01 int or is it correct to add vlan 1 to the first subinterface (fa0/1.1)?

Hi, I might I'm ready for certification but still I wanna make myself sure that I really do. Has anyone of you found pages where you can test yourself and which you'd recommend to me?

Thx in advance.

Hello everyone, I am currently an Information Systems undergrad and I am very interested in the networking field and hoping to become a network engineer. I’m planning to get an internship or an entry level job in the networking field next summer, companies usually come to my university and start hire interns super early like in the fall or spring.

I don’t really have much experience in networking, I took a class back in community college and know a lil bit about TCP/IP, subnet masks, mac adress, etc... there are some networking classes for my major that could help prepare me for my certs but I won’t be able to take them until spring after I complete my gateway classes in the fall.

The question is should I try to drop 2 classes in the fall (I’ve signed up for 4), keep only my gateway classes and start working on CCENT cert? By doing this, my network classes will be open up in the spring and I will prob have a CCENT cert by then. This will prob make my resume looks better and will provides better chances at landing an internship or a helpdesk job.

Hello,

I need to get some practise in and wondered what other people do when working on a lab.

I've got PT and have access to the full CCNA R&S course which comes with PT labs. Do I just work through them repeatedly or are there other pre-built labs?

Alternatively (which I do like doing), do people just build their own labs and experiment?

Cheers

Curious if I'm assigning a vlan to a port (or is it assigning a port to a vlan) what happens if i don't use

switchport mode access

but instead skip it and go to

switchport access vlan <id>
