The Certification Ladder

Are you climbing the certification ladder? If you’re in IT the odds are good that you are. Some people are just starting out and see certifications as a way to get the knowledge they need to do their job. Others see certs as a way to get out of a job they don’t like. Still others have plenty of certifications but want to get the ones at the top of their field. This last group are the ones that I want to spend some time talking about.

Pushing The Limit

Expert-level certifications aren’t easy on purpose. They’re supposed to represent the gap between being good at something and going above and beyond. For some that involves some kind of practical test of skills like the CCIE. For others it involves a board interview process like the VCDX. Or it could even involve a combination of things like the CWNE does with board review and documentation submissions.

Expert certifications aren’t designed to be powered through in a short amount of time. That’s because it’s difficult to become an expert at something without putting in the practice time. For some tests, that means meeting some minimum requirements. You can only attempt your VCDX when you have already passed the VCAP-DCA and VCAP-DCD test, for example. Or you may have a minimum requirement of time in the industry, such as the CISSP requirement of four years in the security industry.

But, more importantly, the requirement is that you truly are an expert. How many times have you bumped into someone that has a certification that you think to yourself, “How on earth did they pass that?” It should be fairly uncommon to run into a CCIE that you feel that way about. The test is rigorous and requires everyone to pass a very similar version of the practical exam. Sure, you still run into people that say the old 2-day exam was harder. But by and large, most CCIEs have had to endure the same kind of certification requirements.

Now, what people do after they get there is an entirely different matter altogether. There are a lot of people that get to the pinnacle of their certification journey and sit there on top of their mountain. They take time to survey the lands that they now watch over and they relax. They don’t see any need in going any further. They’ve done what they came to do. And for many that’s the way to go. Congratulations on your ride.

Still others use this opportunity negatively. They expect people to kiss the brass certificate and pay deference to them because of it. This can affect almost anyone. I remember years ago back to a time when I had just gotten my CCIE lab out of the way. I was working on a proposal for a customer. We had just gotten an email from the customer asking why we didn’t include a particular switch in the design. I told our team that we didn’t need it because the requirements of the design didn’t need something that cost three times over what we recommended. The customer’s response was, “Well, this other partner guy is a CCIE and he says we need that switch.” I replied back with, “Well, I’m a CCIE too, so let’s cut that crap and talk about the hardware.”

I’m not sure how many times that person had used the “I’m a CCIE” justification for their recommendations, but it shows me that some people believe a piece of paper speaks louder than their track record. Those people are usually the ones that fall back into the pattern of “listen to me because I passed tests” not “listen to me because I did the studying”. It’s important to ascribe value to passing a test, but remember that the test is a way to prove you have knowledge. It reminds me of this scene from Tommy Boy:

Throwing up a certification as justification for a recommendation is no different that just tossing a worthless guarantee on a box. Prove you know what you’re talking about instead of just saying you do.

Exceeding Your Reach

The last type of person that climbs the certification ladder is like the one in this tweet from my friend Hank Yeomans:

He looks at the ascent to the top of his certification ladder as a chance to do more. To build more. It’s not the end of the journey. It’s not bad to stop and look around at the new view from the top of your ladder when you’ve climbed it. But if you look at the journey as the start of something that you need to finish, you’re going to start immediately looking around to find the next thing that you need to do. Perhaps it’s learning a new technology related to the one that you just finished. Or maybe it’s that you want to figure out how to get even better at what you do.

People that never rest in their attempts to be better at the ones that ultimately change the way things are done. They don’t just accept that this is the way that things need to be. Instead, they use the top of their ladder to stretch out and see what they can reach. They realize that everything we do in life it just building on something else we’ve already done. We use Crawl, Walk, Run as a metaphor for building through a project or a process all the time. That’s because we know that you have to make steps all the time to progress. But what if someone just said, “You know what, I’ve mastered walking. I don’t need to run. All you people who only crawl listen to me because I’m better than you!” It would show how short-sighted they are when it comes to continuing the journey.

Tom’s Take

Many times, I’ve talked about the fact that I relaxed after I passed my CCIE and enjoyed not studying into the wee hours of the night. But after a while I started getting uncomfortable around 8-9pm. Because there was a little voice in the back of my head that kept telling me “You should be studying for something.” Instinctively, that voice knew that I needed to continue my journey. I would never be content resting on my laurels and I could never bring myself to use my certification as a crutch to make myself look important to others. Instead, I needed to push myself to build on what I’ve already done and make myself better. As Hank said, it’s just a foothill on a greater journey. Once you’ve learned how to use your ladder to increase your reach, even the sky isn’t the limit any longer.

VMware Certification for Cisco People

During the November 14th vBrownBag, which is an excellent weekly webinar dedicated to many interesting virtualization topics, the question was raised on Twitter about mapping the VMware certification levels to their corresponding counterparts in Cisco certification.  That caught me a bit off guard at first because certification programs among the various vendors tend to be very insular and don’t compare well to other programs.  The Novell CNE isn’t the same animal as the JNCIE.  It’s not even in the same zoo.  Still, the watermark for difficult certifications is still the CCIE for most people, due to its longevity and reputation as a tough exam.  Some were wondering how it compared to the VCDX, VMware’s premier architect exam.  So I decided to take it upon myself to write up a little guide for those out there that may be Cisco certification junkies (like me) and are looking to see how their test taking skills might carry over into the nebulous world of vKernels and port groups.  Note that I’m going to focus on the data center virtualization track of the VMware certification program, as that’s the one I’ve had the most experience with and the other tracks are relatively new at this time.

VCP

The VMware Certified Professional (VCP) is most like the CCNA from Cisco.  It’s a foundational knowledge exam designed to test a candidate’s ability to understand and configure a VMware environment consisting of the ESXi hypervisor and vCenter management server.  The questions on the VCP tend to fall into the area of “Which button do you click?” and “What is the maximum number of x?” types of questions.  These are the things you will need to know when you find yourself staring at a vCenter window and you need to program a vKernel port or turn on LACP on a set of links.  Note that according to the VCP blueprint, there aren’t any of those nasty simulation questions on the VCP, unlike the CCNA.  That means you won’t have to worry about a busted Flash simulation that doesn’t support the question mark key or other crazy restrictions.  However, the VCP does have a prerequisite that I’m none too pleased about.  In order to obtain the VCP, you must attend a VMware-authorized training course.  There’s no getting around it.  Even if you take the exam and pass, you won’t get the credential until you’ve coughed up the $3000 US for the class.  That creates a ridiculous barrier to entry for many that are starting out in the virtualization industry.  It’s difficult in some cases for candidates to pony up the cost of the exam itself.  Asking them to sell a kidney in order to go to class is crazy.  For reference, that’s two CCIE lab fees.  Just for a class.  Yes, I know that existing VCPs can recertify on the new version without going to class.  But it’s a bit heavy handed to require new candidates to go to class, especially when the material that’s taught in class is readily available from work experience and the VMware website.

VCAP-DCA

The next tier of VMware certifications is the VMware Certified Advanced Professional (VCAP).  This is actually split into two different disciplines – Data Center Administration (DCA) and Data Center Design (DCD).  The VCAP-DCA is very similar to the CCIE.  Yes, I know that’s a pretty big leap from the CCNA-like VCP.  However, the structure of the exam is unlike anything but the CCIE in Ciscoland.  The VCAP-DCA is a 4-hour live practical exam.  You are configuring a set of 30-40 tasks on real servers.  You have access to the official documentation, although just like the CCIE you need to know your stuff and be able to do it quickly or you will run out of time.  Also, just like the CCIE, you are given constraints on some things, such as “Configure this task using the CLI, not the GUI.”  When you leave the secured testing facility, you won’t know your score for up to fifteen days until the exam is graded, likely by a combination of script and live person (just like the CCIE).  David M. Davis of Trainsignal is both a CCIE and a VCAP and has an excellent blog post about his VCAP experience.  He says that while the exam format of the VCAP is very similar to the CCIE, the exam contents themselves aren’t as tricky or complicated.  That makes sense when you think about the mid-range target for this exam.  This is for those people who are the best at administering VMware infrastructure.  They know more than the VCP blueprint and want to show that they are capable of troubleshooting all the wacky things that can happen to a virtual cluster.  Note that while there is a recommended training class available for the VCAP, it isn’t required to sit the test.  Also note that the VCAP is a restricted exam, meaning you must request authorization in order to sit it.  That makes sense when you consider that it’s a 4-hour test that can only be taken at a secured Pearson VUE testing center.

VCAP-DCD

The other VMware Certified Advanced Professional (VCAP) exam is the Data Center Design (DCD) exam.  This is where the line starts to blur between people that spend their time plugging away and configurations and people that spend their time in Visio putting data centers together.  Rather than focusing on purely practical tasks like the VCAP-DCA, the VCAP-DCD instead tests the candidate’s ability to design VMware-focused data centers based on a set of conditions.  The exam consists of a grouping of multiple choice, fill-in-the-blank, and in-exam design sessions.  The latter appears to have some Visio-like design components according to those that have taken the test.  This would put the exam firmly in the territory of the CCDP or even the CCDE.  The material on the DCD may be focused on design specifically, but the exam format seems to speak more to the kind of advanced questions you might see in the higher level Cisco design exams.  Just like the DCA, there are recommended courses for the DCD (like the VMware Design Workshop), but these are not requirements.  You will receive your score as soon as you leave, since there aren’t enough live configuration items on the exam to warrant a live person grading your exam.

VCDX

The current king of the mountain for VMware certifications is the VMware Certified Design Expert (VCDX).  This the VMware’s premier architecture certification.  It’s also one of the most rigorous.  A lot of people compare this to the CCIE as the showcase cert for a given industry, but based on what I’ve seen the two certifications only mirror each other in number of attempts per candidate.  The VCDX is actually more akin to the Cisco Certified Architect (CCAr) or Microsoft Certified Master certification.  That’s because rather than have a lab of gear to configure, you have to create a total solution around a given problem and demonstrate your knowledge to a council of people live and in person.  It’s not a inexpensive, either in terms of time or cost.  You have to pay a $300 fee to even have your application submitted.  This is pretty similar to the CCIE written exam.  However, even if you submit the proposal, there’s no guarantee you’ll make it to the defense.  Your application has to be scrutinized and there has to be a reasonable chance of you defending it.  If you’re submission isn’t up to snuff, you get recycled to the back of the pile with a pat on the head and a “try again later” note.  If you do make the cut, you have to fly out to a pre-determined location to defend.  Unlike Cisco’s policy of having a lab in many different locations all over the world, the defense locations tend to move around.  You may defend at VMWorld in San Francisco and have to try again in Brussels or even Tokyo.  It all really depends on timing.  Once you get in the room for your defense, you have to present your proposal to the council as well as field questions about it.  You’ll probably have to end up whiteboarding at some point to prove you know what you’re talking about.  And this council doesn’t accept simple answers.  If they ask you why you did something, you’d better have a good answer.  And “Because it’s best practice” doesn’t cut it either.  You need to show an in-depth knowledge of all facets of not only the VMware pieces of the solution, but third party pieces as well.  You need to think about all the things that you would put into a successful implementation, from environmental impacts to fault tolerance. Implementation plans and training schedules could also come up.  The idea is that you are working your way through a complete solution that shows you are a true architect, not just a mouse-clicker in the trenches.  That’s why I tend to look at the VCDX as above the CCIE.  It’s more about strategic thinking instead of brilliant tactical maneuvers.  Read up on my CCAr post from earlier this year to get an idea of what Cisco’s looking for in their architects.  That’s what VMware is looking for too.

That’s VMware certification in a nutshell.  It doesn’t map one-to-one to the existing Cisco certification lineup, but I would argue that’s due more to the VMware emphasis on practical experience versus book learning.  Even the VCAP-DCD, which would appear to be a best practices exam, has a component of live drag-and-drop design in a simlet.  I would argue that if Cisco had to do it all over again, their certification program would look a lot like the VMware version.  I talked earlier this year about wanting to do the VCAP in some form this year.  I don’t think I’m going to get there.  But knowing what I know now about the program and where I need to focus my studies based on what I’m doing today, I think that the VCAP is a very realistic goal for 2013.  The VCDX may be a bit out of my league for the time being, but who knows?  I said the same thing about the CCIE many years ago.
