Actually I am using the CCDA EXAM Certificate Guide, Top Down Book, and Boson, But I am probably doing it slightly backwards, I am getting about 96 or 98% on the Boson EXAMS (All 12), I read The TOP Down Book first, and Dwelled on the BOSON EXAMS, when I didn't get the answer correct, I would read either Top & Down or the CCDA EXAM guide for Clarification.

To be honest the real reason to pursue the CCDA was to answer 1 or 2 questions. I actually work for investors, and constantly do business cases for satellite communications, And one of the question I am always running into, is the following:

If you are extending the Internet VIA satellite to a Developing Country how much throughput do you need, I know most people say it depends, the niche I found my self I would assume certain Parameters, take for example you were to service 1000 Subscriber in Lagos, Nigeria and you were using Frame Relay (Wireless) technology, and A Satellite Earth Station for the Backhoe Link to the USA and wireless access for the last mile. What would the required link be if the CIR was 16Kbps, and the PIR 64Kbps. You see for every DSO over the satellite it could be 30K per month or 3K per Month, In any case You can see that if I simply added the CIR with the amount of QTY (Like the TOP DOWN BOOK SUGGESTS), I could never make a business case, so I had to assume a certain usage. Each Person would pay thousands of dollars for internet services. I actually found my answer through Newbridge courses, they had some normal traffic behavior(For Internet) that I could use. Recently the combination of DVB and TDMA (Frequency) hopping has provided a mature access scheme that squeezes every last bit into the RF B.W over the satellite. The combination of the latest satellite access methods and frame Relay Technology can bring the sale price down to a reasonable level while still providing profit to the Operator and Investor (And maybe some for myself)


I hope you got that all but since you have experience I can bridge my Telecom with your IT experience,

I can go into details if you wish but I have done this for 46 Countries now, (Extending the Internet, Voice and DATA), However my Demark has always been V.35 or 449 interface of the router or Multiplexer and I thought it would be a natural to learn more about the IT world through the Cisco using the Certificate route.

The reason I went into all this is maybe you can advise me after A I pass the CCDA (I assuming I do), were do I go next, and further do you believe with the above information (The scope of the work), I could find the right personal here to support my efforts?

Tom,

In response, I put your last message here as it is off topic for the last thread and I think if we don't start a new thread, at the least we'll confuse folks, or at the worst piss off the moderators. ;-)

Anyway, I don't have a lot of time to go over your post in detail right now, but you're on the right track. 1) no matter what $$$$ rules. So if you can't cost justify something management won't approve. I know you know this but others reading this probably have to be reminded of this. 2). Certification is an individual thing. I never got a MCSE because I was busy with dealing with client's projects and problems with my ex-wife. Kind of wish that I had done it way back when. But I'm not going to make the same mistakes and I'm busting butt to get my Cisco certs. One down, 4 to go (CCDA, CCDP, CCNP, and then CCIE)

My opinion is that you finish what you've started with your CCDA and get it. Since the CCNP and CCDP are almost the same (except for the design exam requirement) you might as well get both. If you go on to CCIE should just depend on how things go over the next year or two. Life has a funny way of changing things along the way. But whatever you do, keep getting all the info that you can, and learn as much as possible from as many sources as possible.

Gotta run right now.

Tom
