Cisco CCNA Certification: Should You Take The One

Cisco CCNA Certification: Should You Take The OneExam or TwoExam Approach?

by: Chris Bryant, CCIE #12933

One question I’m often asked by CCNA candidates is whether to take the ขone big examข, or take the two separate exams required by Cisco to achieve the Cisco Certified Network Associate (CCNA) exam.

The question comes up because there are now two separate paths to the CCNA certification. Candidates may take a single exam, 640811, or two exams, 640821 and 640811.

What’s the difference? The twoexam approach involves exams with different topics and therefore different preparation techniques. 640821 is the Introduction To Cisco Networking Technologies exam. This course does introduce the candidate to Frame Relay, PPP, and other WAN technologies, but goes into little detail. Emphasis in the Intro course is placed on knowing how Ethernet behaves, how different types of cable are used for different purposes, and knowing what cable to use in a certain situation. The candidate should expect some questions involving binary math as well, but they will involve fairly simple conversions.

The 640811 exam, Interconnecting Cisco Networking Devices, goes into much more detail on WAN technologies. Routing and switching behavior are covered, and the candidate is expected to answer difficult questions involving binary math and subnetting as well. The candidate may also have to demonstrate ability to configure a router or switch via a simulator. Since the ICND exam goes into more detail, it’s generally considered the more difficult exam.

The approach I recommend to a CCNA candidate depends on their background. If the candidate is a relative newcomer to networking, or hasn’t taken a certification exam before, I recommend they take the twoexam approach. This allows the candidate to focus only on the Intro topics, and gives them a strong sense of confidence after passing the Intro exam. That confidence flows over into the ICND exam.

For those who have networking experience, and are very familiar with Ethernet behavior and cable types, I recommend the oneexam approach. This allows the candidate to focus on the more advanced topics they’ll be seeing in the single exam, while spending just a little time reviewing their Introlevel knowledge.

Regardless of the approach you choose, the path to true CCNA success remains the same. Get some real handson experience, either by renting rack time online or by putting together your own home lab. Understand what’s going on ขbeneath the commandข; don’t use router commands when you don’t understand what they’re doing. Add to that a true mastery on binary math, and you’re on your way to having the magic letters ขCCNAข behind your name!

Cisco Certification: How To Build Your Own Home La

Cisco Certification: How To Build Your Own Home Lab

by: Chris Bryant, CCIE #12933

CCNA and CCNP candidates hear it all the time: ขGet some handson experienceข. From my personal experience climbing the Cisco certification ladder, I can tell you firsthand that there is no learning like handson learning. No simulator in the world is going to give you the experience you will get cabling and configuring your own routers.

Whenever I mention this to one of my students, they always say it costs too much. The truth is, it is cheaper now to build your own CCNA and CCNP lab than it has ever been. The secret? Used routers.

The word ขusedข turns off a lot of people not many of us buy used computers or used servers. Cisco routers, though, are robust. I personally own a Cisco 4000 router that I use as a Frame Relay switch in my lab that I’ve had for about four years, and I’ve never had a problem with it.

The good news for current CCNA and CCNP candidates interested in building their own labs is that used Cisco equipment has never been more plentiful or cheaper. eBay is a good way to get an idea of what’s out there and what the prices are, but you don’t have to assemble your lab one piece at a time. Many eBay vendors who sell used Cisco equipment sell readymade CCNA and CCNP labs for one price, including cables.

I asked one major vendor of CCNA and CCNP labs, www.ciscokits.com, what the most common questions are regarding building your own home lab. Here’s what they had to say:

Why do I need real routers instead of a simulator?

You need a physical router,as the simulators just don’t have the ability to give you the ขhands onข you need to see what happens when you disconnect a cable or put a cable in the wrong location. You will come to find quickly that mistakes you make on Router 1 are affecting Router 5 all because you did not screw in a cable properly. No simulator can simulate that.

How many routers do I need?

Two routers really are required to see if anything works. If you have a very limited budget, you can receive value from only purchasing a single router over working with a simulator. However, you will not be able to see the main thing we are trying to accomplish. The propagation of route tables!

The only way you can see if your configurations work, is to have at least two routers. Therefore, I strongly recommend that you purchase a dual router kit that comes with all the accessories you need. Otherwise you can spend days trying to find all the little extra pieces you need to get your lab up and running.

Do I need a switch?

Well, it is nice to have. However, with only about 2 questions on the test dedicated to ขhands onข switch knowledge, if you have to skimp on something, skimp on the switch.

What routers and switches should I buy?

Choices, choices, choices! Which 2500/2600 router do I pick? I will list some pros and cons of each router below, along with current prices (note that prices are generally lower if you buy a dual router kit instead of a single router). Please note that prices are approximations.

1) Cisco 2501 Router with 16 MB Flash/16MB DRAM $94.99. The cheapest introduction router, and it can support a vast majority of the commands that you will need to learn for your CCNA test. All 2500 routers that we will discuss come with a minimum of two serial ports and an Ethernet port.

You will need to add a transceiver to this unit to convert the Ethernet AUI port to an RJ45 style Ethernet port.

2) Cisco 2503 Router with 16 MB Flash/16MB DRAM $119.99. This is the same as a Cisco 2501, except it adds an ISDN port so you can complete all your ISDN commands for the CCNA test. You will need to add a transceiver to convert the Ethernet AUI port to an RJ45 style Ethernet port.

3) Cisco 2505/2507 with 16 MB Flash/16MB DRAM $109.99. The same as a Cisco 2501 except it has a builtin 8 or 16 port hub so you do not have to purchase a transceiver.

4) Cisco 2514 Router with 16 MB Flash/16MB DRAM $149.99. This router is the same as a Cisco 2501 except instead of one Ethernet port you have two. You may ask, what is the big deal? Well, you can use this as your Cable Modem/DSL Modem router. Now you can test your ability to setup a firewall and router in a live environment on the Internet. Lots of fun! You will need to add two transceivers to convert the Ethernet AUI ports to an RJ45 style Ethernet ports.

5) Cisco 2520 Router with 16 MB Flash/16MB DRAM $119.99. This is the same as a 2503 but it also adds two more serial ports so you can use this as a frame relay switch later in your CCNA studies. It costs the same as a 2503, so this is a great money saving tip.

6) Cisco 2612 Router with 32 DRAM and 8 MB Flash $199.99. This is a modular router unlike any of the 2500 series routers. So the big benefit of this is you can buy extra modules to add functionality such as more serial ports, ISDN ports, Ethernet ports, WICs and such. However, due to the flexibility you will pay a bit more. One day it is a frame relay switch, the next it is your ISDN router. In the long run it will be cheaper than purchasing a bunch of dedicated routers for each

discipline you want to learn.

7) Cisco 1912 or 1924 Switch with Enterprise Software $109.99. This is a good low cost switch. The only drawback is it is a 10 MB switch except for the two 100 MB uplink ports. Not a big deal since you have 10 MB routers.

8) Cisco 2912 or 2924 Switch with Enterprise Software $249.99. This switch will run all the current commands needed for the test and is a full 100 MB switch.

And should you desire to sell your lab after you complete your certification, you can either negotiate a price with the vendor who sold it to you, or you can sell it yourself on ebay. It’s my experience that 95% of candidates who earn their CCNA go on to pursue their CCNP within one year, though, so don’t sell it too quickly.

In the end, you spend only a few hundred dollars, and you gain invaluable experience and knowledge that will help you both in your certification quest and your job performance. Having worked my way from the CCNA to the CCIE, I can tell you that you will learn much more from actually configuring and cabling your own equipment than you ever will from any simulation of the real thing.

To your success,

Chris Bryant

Cisco CCNA Certification: Why You MUST Have Hands

Cisco CCNA Certification: Why You MUST Have HandsOn Experience

by: Chris Bryant, CCIE #12933

CCNA and CCNP candidates hear it all the time: ขyou have to get some handson experience to pass the examsข.

Candidates tend to think that’s just so they can solve the simulator problems, but that’s only the more obvious reason.

First, I want to make it clear that I’m not bashing learning from books you have to learn theory before you can really know what’s going on in the first place. The key is that to truly understand routing and switching processes, you’ve got to have that handson experience.

So if the simulator questions are the more obvious reason to get handson experience, what are the less obvious reasons?

Glad you asked!

You see what happens when things don’t go according to the script. One of the biggest problems with learning your skills on software programs such as ขrouter simulatorsข is that with simulators, things go pretty much as planned.

I have news for you: that doesn’t always happen in the real world. While Cisco routers and switches are highly reliable devices, every once in a while you’re going to get an unexpected result from a command. Maybe it didn’t work after you typed it in maybe it has an effect on your prior configuration that you didn’t expect. Maybe you don’t know what happened – you just typed in that command and the router went nuts!

Sooner or later, that’s going to happen to you in the real world. And as I tell my students, it’s actually a good thing to have happen to you in a lab.

You don’t learn to troubleshoot or finetune a configuration when everything works perfectly. You don’t learn much at all when things go perfectly. And you’re practicing to learn!

I often say that great chefs don’t learn to cook on cooking simulators they learn in the kitchen, and they burn a lot of meals on the way to greatness. You need to screw up some configs on the way to greatness, and you can’t do that on a computer program. You have to be on the real thing.

You build confidence by working with real Cisco routers and switches. Would you want the Super Bowl to be the first football game you ever really played in? Of course not. Then why would you take router configuration exams and be nervous about having to create a VLAN, or troubleshoot an OSPF configuration?

You cannot walk into the testing room a nervous wreck. You must have the attitude that you are already a CCNA or CCNP, and you’re just there to make it official. I can tell you from firsthand experience with many students that the way you develop than confidence is to work with the real deal.

You can’t buy that confidence, and you can’t simulate your way to it. You’ve got to work with real Cisco routers and switches. By working with the real equipment, you develop the real skills and real confidence you need to pass the CCNA and CCNP exams.
