Be careful what companies you give your certification numbers to.

We recently had a case where a partner company was decertified for multiple violations of the partner agreement. They attempted to dodge this disciplinary action by re-registering under a different name. Some of the key tools that made that possible were the CCIE numbers of two part-time employees. Since it appeared that those employees were willing participants, we banned them and put a block on their certifications.

Further investigation revealed that the part-time employees were just pawns, innocent bystanders who did not know their certification numbers were being used to intentionally violate the Cisco Partner Agreement. The block on their profiles has since been lifted, but only after weeks of nervous anticipation, as they waited to see if they would be banned for life from any and all Cisco certifications.

Lesson 1 from this incident is to vet potential employers you will be giving your cert number to as best as possible. As with anything of value, your cert number is not something you want to hand over to just anyone. And while you won’t always be able to predict that an employer will become unscrupulous down the road, due diligence on your part may help weed out some companies and will at least send a message to others that you do not hand over your cert number lightly.

Lesson 2 is that, when you leave a company, you make sure to take your cert number with you. Update your information in the candidate database just as you would a new email or postal address, being very clear about when you moved on and when the old company should have stopped using your number.

Hi Praveen,

I am not working for Cisco but I have delivered tremendous number of Cisco training classes for Cisco employees around the globe starting from CCNA and ending by CCIE in almost all the specializations.

I can simply tell you that if you really keen to be a Cisco employee, you have to achieve 2 important points:

1- Usually thinks in how you could add to the team that you would like to join. Big companies like Cisco are usually looking for people that will add a value not for people that will get a value.

2- Build very strong communications with Cisco’s employees in the area that you are willing to join. The majority of Cisco’s employees that I have met were referred from their friends or their connections due to their potential skills that they may add to the company.

#01 Nicholas Ong

Like the subject says it, I find it weird that there is no mention of the renewal of the basic CCNA when upgrading to the new concentration which sounds quite weird since the new CCNA concentrations can be renewed by taking same level exams - other CCNA concentrations, CCNA or CCDA.

#02 Andrew

Individuals passing any current CCNA concentration exam (wireless, security, voice) will automatically recertify their expiring CCNA concentration, CCNA or CCENT certification. Passing any 642 professional level exam or written CCDE or CCIE exam will also recertify a CCNA Concentration.

#03 Nicholas Ong

Hi Andrew, Do you know if taking the CCDA exam will renew the CCNA as well?

#04 Cisco Moderator

Sorry, the CCDA will not recert the CCNA. Please review the recertification policy listed below. This is also listed on the CCNA syllabus page.

https://cisco.hosted.jivesoftware.com/community/certifications/ccna/syllabus?view=overview

CCNA certifications are valid for three years. To recertify, either pass the current CCNA exam, or pass the ICND2 exam, or pass any 642 professional level or Cisco Specialist exam (excluding Sales Specialist exams), or pass a current CCIE written exam.

It’s telling to watch how young children, as they mature, confront physical or intellectual challenges, applying as much perseverance as their abilities permit, while keeping the effort entirely within the context of having fun. As a parent this process can manifest itself at the playground where my daughter Annika, after spending a few weeks trying to master the monkey bars, will finish, satisfied with her accomplishment…for a while…until ambition leads her to gaze at the giant climbing rock, the next challenge, just across the playground.

I’m excited to introduce you to our new playground, the Cisco Learning Network. Its intent is to assist you in defining your professional goals; planning a strategy to execute; and facilitating success via Educational content, peer exchanges in the Discussion Forums, and finally career guidance as you continue to strive for opportunities provided through your continued Education and Certifications.

Whether your interest is in being introduced to Cisco Certifications; working to prepare for your Entry, Associate, Professional, or Expert Certification; looking for a refresh before taking your re-certification exam; checking in on what people are blogging about; or just stopping by to see what’s new in our ever expanding technical library, we fully expect you to either find what you are in need of, or to let us know what’s missing and we’ll work to correct that.

The exciting news this month, above and beyond the introduction of Cisco Learning Network, is the simultaneous introduction of our newest Associate Certifications: CCNA Wireless, CCNA Voice, and CCNA Security. The continued goal of the Cisco Certification process is to provide ample Certification opportunities for all the different technology frameworks within the four primary Certification levels (Entry, Associate, Professional, and Expert), and we trust the new CCNAs will complement the existing Certifications.

Providing Certification resources and guidance can be a slippery slope; we don’t want to surprise candidates regarding content and exam topics, but we want the Certifications to be an accurate gauge of one’s abilities and competencies, to stand on its own merits, and to continue to be a badge of honor within the Network Community. We all have a vested interest in the continued success of Cisco Certifications, and so we depend upon your feedback to regularly monitor the state of that art.

The Cisco Learning Network is here to help you meet your professional goals, while also establishing new challenges—a process that hopefully leaves you as satisfied yet eager as that 5-year-old on the playground. Let your determination inspire us all. And just as I tell Annika: have fun, play nice, and let me know when you need help.

Anweesy3’s Question:

I am a current CCNA pursuing the CCNP. I have the ONT and ISCW left to take. This new CCNA Security cert seems very valuable since I want to pursue security. I was wondering since the CCNA Security and ISCW have very similar topics, can I bypass purchasing the exam guide for the IINS 640-553 and use my study materials for the ISCW instead? What are your opinions?

List of helpful answers:

It is better to continue with the CCNP track, as you said ONT and ISCW left to take. You can go through the syllabus which is given in this site itself and compare with the ISCW. It is better to wait for CCNA security as it is a fresh paper recently released. Even i am preparing, but planning to take this exam after one month. We can get more views, and details about the paper.

I am using SND and SNRS for my prepartion. Just go for the link and I hope this will clear it..

http://www.cbtnuggets.com/webapp/product?id=445

My advice is to take for CCNP and meanwhile material will be available.. and then go for the security.

—— Naresh

Just so you are aware, Cisco Press has two product out for the CCNA Security Exam. They are:

• CCNA Security Official Exam Certification Guide (print book with CD test engine)
• CCNA Security Quick Reference (digital review product)

Hope that helps!

Vishal’s Question:

I will be taking 640-802 exam in a couple of months. I thought that I would save USD $125 by taking this single composite exam(which’s USD $125) option rather than going for two exams option(ICND1 & ICND 2) which is USD $125 each. But today when I try to register myself for the exam, I find that 640-802 is USD $ 250 NOT 125 & ICND1 &ICND2 are $25 each. Did Cisco revised the fee for 640-802 or i was wrong in the first place??? If somebody could please tell me if Cisco gives us some option to save moeny by going for a certain option.

List Of Helpful Answers:

Unfortunately, Cisco have increased the prices for the CCNA exams (both for the CCENT route and the single 640-802). Therefore it will cost the same, in monetary terms, to take the single CCNA or the double exam route. — Jordan Mazurke

As of June 24, 2008, the price of the CCNA comprehensive exam #640-802, the single exam option for achieving CCNA certification, will be $250 USD, the professional-level Composite exam #642-892, will be $300 USD and the CCIE written exams will be $350 USD or the local currency equivalent in all regions. All other exam prices still apply. If additional charges are incurred, please contact Pearson VUE at www.pearsonvue.com/cisco/contact. — Andrew
