Background/Story
Since I used to be a child, I used to be fascinated by many issues I discovered attention-grabbing. I grew up being the nosy child, or “preguntón,” in Spanish. I used to be nearly at all times asking “why?” at any time when I acquired one thing defined or instructed, which might drive many of the adults to madness after a few hours with me.
My mother, in an try and get this matter solved, gave me a guide known as “El porqué de las cosas,” which roughly interprets to English as “The why of the issues.”
I may spend hours studying and asking much more questions. It was an countless loop I loved as a (un)naturally curious child. To my shock, the guide had a number of volumes explaining issues all of us surprise about, however not many people have the drive to lookup, or “to Google,” in at this time’s parlance.
Years later I thank my mother for such a superb transfer; I picked up studying in my early years and continued to develop keen on it. Encyclopedias (do any of you keep in mind Microsoft Encarta?), novels (Potterhead right here!), tales, newspapers, and my profession subject: IT.
I began tweaking my very own laptop when it felt gradual, as I needed to play the cool video games different children have been enjoying. Over time, it morphed into cracking video games, modifying registry keys, disabling/enabling companies, troubleshooting issues, and operating a shared LAN (Hamachi) to play with my associates — the chances have been countless!
Touching and troubleshooting programs, putting in gadgets, and connecting cables and printers (gadgets from hell!) turned pure, and I began making a residing out of it once I was 16 years outdated. It naturally grew into networking, and that’s precisely the place my story with Cisco, being it Academy, certifications, boards, all of it!
As I turned a community engineer, the urge to understand how issues labored simply made it pleasurable and compelling. There was an invisible world to us underneath cables, numbers, and blinking lights. I discovered an countless curiosity effectively (or hose) I may drink from each day.
Why CCDE?
Round 2016, after a number of years as a community help engineer, I made a decision to check community design. However why? By that point, I labored with many engineers and will see a distinction between them. Some have been pleased to implement issues and see them working, generally with out them being fully clear to them. And another engineers, although, knew very effectively how issues labored and why the modifications have been being launched. That they had a distinct perspective.
That instantly caught my consideration; I needed to know the explanations behind issues. I was curious! At the moment, the CCDE neighborhood was rising and all people was so vibrant and welcoming that I acquired lured into it. I made a decision that although it will be a tough factor to do, I needed to check community design.
You might be normally instructed that CCDE is a certification for skilled engineers and, given the quantity of data required, it is best to have not less than one CCIE earlier than making an attempt it. It initially discouraged me—till I spoke with individuals like Elaine Lopes, Daniel Dib, Jeremy Filiben, Mark Holm, and Andre Azevedo. They assured me you that don’t want a CCIE to aim the examination, however you do want the information that comes with it. (Notice that each one of them have not less than one CCIE!)
Like my good good friend, Peter Palúch, instructed me a number of instances: “You should be on the identical degree. Make expertise your second nature, and perceive issues right down to the bone.”
That 12 months, I began learning and assessing myself truthfully, in search of areas to enhance. I aimed for CCDE and the huge information it will require.
I initially took the CCDP* examination to gauge myself, which lined not solely fundamentals but in addition finest practices; what was really useful given sure circumstances. After passing, I keep in mind feeling energized and prepared for extra.
Again then, I assumed: “What if I attempt the CCDEv2 written examination?”
Narrator: “And with out realizing, David was setting himself up for a candy and skin-scorching lesson.”
My Cisco certification examination journey
It took me three makes an attempt and loads of learning to cross the CCDE written examination. The primary one was my approach of gauging myself, whereas the second failure felt excruciatingly shut. Lastly, my third try was a candy cross.
The CCDEv2 written examination was a beast. It primarily mixed Enterprise and Service Supplier subjects, whereas additionally including some safety as effectively, making it a mighty difficult examination by itself.
Was all my learning sufficient to cross the written examination? Sure. Barely.
Was I able to take the CCDE sensible examination? Not likely. Not emotionally… and much much less technically. However that was a lesson I discovered over time after incomes myself a few scars.
From August 2017 till Might 2018, I studied extra, I mentioned extra, and I assumed it was time. I had heard so many issues in regards to the examination; the type of the check, the quantity of data, the studying and highlighting. It appeared doable.
Then, my examination day got here! There I used to be in Madrid on Might 30, 2018, arriving sooner than anyone else! The testing heart wasn’t opened till 10:00, although the examination was supposed to begin at 09:00. Don’t ever ask a Spaniard to get up early, or you’re setting your self up for failure! 😀
It was precisely like I had heard—however on steroids! The data, the emails, the diagrams, the questions. I assumed I used to be prepared for it, however I wasn’t. The examination made me notice that rather more was wanted; extra information, extra studying, extra expertise.
Typically, that meant that I didn’t perceive a specific expertise effectively sufficient. Different instances, that meant I had missed said necessities or constraints or was not in a position to focus for all the time of the check (8 hours).
This occurred twice in 2018, in Might and November. On each events, it was a FAIL for me.
After getting crushed twice, I continued making an attempt. Out and in, it was powerful to get on my toes once more.
In between my makes an attempt in 2018 and 2019, I additionally took different exams to check my information and get myself nearer to the “CCIE-level” information I wanted earlier than I confronted the beast as soon as extra.
I used to be in a position to cross the CCIE R&S** and Service Supplier exams whereas getting ready for the following out there makes an attempt for the CCDE examination. It felt nearer, knowledge-wise, in addition to in examination expertise.
In 2019, I went for it once more. Twice. Each instances, I used to be visiting Frankfurt. And sure, though it felt higher, smoother, and clearer, it wasn’t sufficient. I failed each makes an attempt that 12 months and thought of taking a break earlier than going through the examination once more. I didn’t know, nonetheless, that my break can be all that lengthy.
Taking a break
Between 2019 and 2022, loads occurred in my life. (And possibly yours too!) A pandemic, modifications in my private and work life, amongst different issues. I devoted time to understanding myself (I began visiting a psychologist) to discover what else was inside past the technical acumen.
I used to be not prepared but, technically and personally. However I wasn’t in a position to see it. I used to be too proud to confess it and too cussed to cease making an attempt. I used to be solely bullying via the makes an attempt and pushing additional.
What would you assume after an try?
- I used to be not studying quick sufficient.
- I used to be studying too quick.
- I missed the necessities.
- I missed that constraint.
- Did they are saying you couldn’t do X?
- I should have missed X expertise.
- I couldn’t keep targeted all through all the examination.
- I introduced preconceived notions into the examination.
- No person does that in the actual world!
- I shouldn’t have second-guessed myself…
- God, I hate tables!
Every a kind of makes an attempt teaches you one thing, however you must listen. In any other case, it goes over your head, and you find yourself bumping into the identical stone once more. Every lesson burns your pores and skin within the course of, or not less than, that was the sensation for me. Taking the examination was akin to being a meteorite getting nearer to the earth: the extra you method it, the mightier the burn and items of you proceed to fall except you brace your self.
In my case, I used to be not in a position to see the forest due to the timber. Though it sounds humorous, it was the case. I used to be an issue as an alternative of zooming out and searching on the massive image with all the shifting items.
What else occurred throughout my break? Nicely, CCDEv2 was revamped to CCDEv3, and subjects have been adjusted, together with the exam-taking expertise. Much less Service Supplier, and extra Enterprise, extra Safety, extra Information Middle, extra enterprise, extra Cloud, and extra Wi-fi!
Earlier than persevering with with my story after the break, we may speak about which issues are vital to your CCDE journey. Don’t fear. We can be shedding some tears in a bit.
What do it is advisable cross the examination?
Examine group and associates – AKA neighborhood
Your examine group may very well be the important thing useful resource it is advisable cross. The extra views you get, the higher your technical arsenal can be when going through the examination.
Throughout my CCDE journey, I had the posh of learning with individuals like Mike McPhee, Jason Beltrame, Bruno Wollman, Fareed Fakoor, Remington Unfastened, Ronald Lopez, Anti Sourdi, Freerk Terpstra, Nicolas Vallet and Fabian Beck. All of them are sensible engineers/architects, and so they all taught me one thing alongside the best way. We shared suggestions and information, had classes to show others about what we have been good at, and naturally, made lovely bonds within the course of.
On prime of that, I had great associates who weren’t learning to take the CCDE examination however have been supporting me and educating me issues (train me your secrets and techniques, grasp!) or supporting me as an individual, as a good friend: individuals like Peter Paluch, Daniel Dib, Mark Holm, Martin Novak, Ivan Zlatkov, David Chapcak, Matt Saunders, Kurt Claes, Peter Haluska, and Martin Duggan.
A bunch of associates and examine buddies, individuals to debate with, individuals keen to pay attention, a flooring that might help me… a neighborhood. With out them, I might not have handed it. This late success was due to them for his or her unwavering help and motivation. It’s as a lot mine as it’s theirs.
Each time I felt like quitting (particularly the final two makes an attempt) I used to be supported by them. (Particular point out to Peter, Daniel, Kurt, and Mark!) By individuals who, not less than at that second, believed in me greater than I did. They saved me on monitor, pulled my ears when wanted, and hugged me onerous sufficient to drag my items collectively once more once I couldn’t do it myself.
Know your self
One other vital a part of your journey is to know your self. This would possibly sound like a cliché for a lot of, however it’s tremendously vital, or not less than it was for me.
The CCDE examination is completely different from another CCIE examination. It doesn’t depend on muscle reminiscence or quick typing. You will need to take into account every possibility, learn each doc, and consider each alternative. It’s an 8-hour-long studying comprehension examination with technical and enterprise subjects. Your psychological state is paramount.
- Have you learnt while you examine one of the best? Is it through the morning, afternoon, or evening?
- How briskly are you able to learn?
- How a lot of that may you keep?
- Are you able to deal with eight hours of learning?
- What about 4-hour or 2-hour blocks?
- How good is your focus? (I get distracted simply.)
- How do you deal with nervousness?
- How do you calm your nerves?
- Are you into meditation? Or do you do a fast collection of 20 pushups and really feel like new and targeted?
- What about your emotions in regards to the examination?
- How do you’re feeling when getting into, leaving, and through the examination?
- Anxious?
- Nervous?
- Scared?
- Relaxed?
All these items have been vital for me, and I want I might have thought of them beforehand. I needed to be taught to contemplate them after each failed try.
Initially, my drivers once I began all this have been: ambition, delight (moderately hubris), and worry. I needed to get as excessive as attainable, to be actually good at one thing, to be acknowledged, to close up each mouth that mentioned (there have been many) that I couldn’t make it or it was too onerous and I used to be going to fail, and in addition, my worry of lacking out (FOMO).
An exquisite music about that is Vienna, by Billy Joel.
Over time I discovered (due to my pricey good friend Peter Palúch, my psychologist, and a ridiculous quantity of introspection) that though my earlier drivers helped me to remain motivated and depart the nation, I used to be not going to make it any additional with adverse feelings, they might chew me up ultimately. What can be higher? Discovering optimistic motivation!
I did my finest to cease evaluating myself with others and solely evaluate myself with David from the previous. All of us have failures, everyone knows one thing any person else doesn’t, and all of us can be taught one thing from others. Even the individuals we don’t like can train us one thing.
I began trying on the journey in addition to the objective. I didn’t cease chasing the solar, however I began to benefit from the view whereas I used to be doing it. I additionally began to understand extra of what I used to be doing, what I used to be studying, and what I used to be making, as an alternative of considering, “I gained’t have sufficient time in my life to do all of the issues I wish to do; I have to go quicker.”
Lastly, and the toughest one: I did my finest to cease worrying in regards to the examination’s end result. In any case, I had already failed a number of instances. Will it burn extra? Perhaps a bit. Will or not it’s a disaster? Not likely. Simply choose up your items, regroup, and sort out it once more. The examination is already worrying sufficient, and worrying about failing earlier than taking it can solely make me really feel extra anxious.
Don’t beat your self up beforehand. Give your self an opportunity, forgive your self, and be sort to your self. All of us make errors. Belief me, you’re sufficient. You are able to do it. You will have it in you.
Throughout my final try, I used to be targeted on the examination itself, and the evening earlier than I assumed: Well, no matter occurs, I’ll give my finest through the examination. Move or fail, it is going to be one of the best of me.
I didn’t know if I handed, and I used to be about to verify the following out there date for the examination. Little did I do know that I might cross this time, however extra on that later.
Narrator: “After which David ugly cried for hours as a result of he was a llorón when he knew he handed.”
Again on monitor
After the break, I used to be again on sq. one: the examination was revamped to model 3. Its contents had modified, and my written examination (legitimate for 3 years) had already expired.
What was the very first thing to do? Take the written examination once more! I used to be fortunate sufficient to have a final likelihood earlier than the CCDEv2 written examination can be retired on November 1, 2021.
I brushed up on all of the subjects and studied for some weeks earlier than feeling prepared and, after all, having the looming shadow of the soon-to-be-retired examination over my head. To my luck, I handed, as soon as once more with a candy 860. I can not lie about this: it was superb.
I earned the fitting to take the sensible examination once more, nevertheless it was a brand new model. The examination subjects have been step one to take. I had new issues to be taught: Wi-fi, Cloud, and Safety. And likewise others to brush up and eventually be taught effectively: QoS, and multicast.
Now, the examination was supplied in Brussels like another CCIE examination, so I didn’t should juggle balls to guide an examination in a Pearson Skilled Middle in Frankfurt or Madrid. I may go to the Cisco workplace in Brussels like all people else!
Additionally, a number of associates work there, so it’s a acquainted place for me.
In the middle of ten months, I visited Brussels 4 instances. Each time, I used to be welcomed by my pricey good friend Peter Palúch and supported until no finish by him and Kurt Claes.
My first try was an exploratory one. I had completely no hopes of passing. I needed to see what was completely different: the brand new engine, the brand new eventualities, the type, the expertise. And, God, I did.
I got here out of the examination trying like a fish in a fridge: eyes and mouth vast open, however I couldn’t see or say something. So many new issues to meet up with, extra tech, extra enterprise, and the testing engine was cooler and simpler to make use of. (Not every thing was adverse!)
I spent loads of time studying about Wi-fi, one of many weakest areas in my technical acumen. Freerk Terpstra and Fabian Beck gave me a masterclass on many issues, they defined particulars, deployments, authentication, and the character of wi-fi networks, it was intense! Freerk even created a mini CCDE situation and defined it to us intimately.
I went once more in February with loads of hopes, nonetheless, it wasn’t but my time. Regardless that I felt higher, extra assured, and happier with my efficiency, it wasn’t sufficient. I noticed I wanted extra cloud, extra migrations, extra enterprise acumen, extra studying expertise, and extra focus. It was an countless record!
I saved a listing of subjects I felt not sure about and added extra after each try. The record began big and continued to shrink over time whereas I addressed extra subjects—till the final try.
For the June try, I put loads of effort into learning. My Cisco Stay US session catalog was all about issues I wanted for the examination, together with a CCDE techtorial with Mark Holm, Zig Zsiga, and Rick Bauer, and a number of other classes about design.
There I used to be within the CCDE Techtorial: “Dude, don’t inform me this bull****, I already took the examination!” (I’m sorry, Mark.)
I wasn’t making any associates throughout that session. Seems that some discussions aren’t about absolutes or sides, they moderately fall right into a grey space proper within the center, and there are a number of shades of grey to take care of. Some assumptions are honest, however an excessive amount of of that journeys you off. You find yourself strolling on a tightrope like a circus performer whereas the drums resonate within the background.
I felt assured and proud. I did my finest and felt prepared for the examination. Proper after Cisco Stay US, I headed again to Brussels for my third try at CCDEv3.
I labored on my information, note-taking, studying, and focus and mentioned with the already-certified CCDE people I knew. I felt prepared. This was my time. I used to be excited whereas taking the examination. It felt good, it felt like a breeze, and I used to be nearly positive.
I got here out hoping for one of the best and was shot down by a FAIL. It was, by far, probably the most painful of the makes an attempt. I felt misplaced, that I didn’t know what to work on anymore, and that I used to be not in a position to conquer such a titanic objective after so lengthy. My scores have been exhibiting some enchancment after each try, and but, I failed once more and was terribly confused.
It took me a number of days to even course of so many issues and deal with my emotions. And once I was about to throw the towel, my associates have been there for me. As soon as once more, they held me up, they assured me I used to be shut, and so they gave me extra encouragement than I may have requested for.
I felt like Spiderman (Tobey Maguire) getting carried over their heads after saving the individuals on the practice from an imminent crash. However this time, I used to be the one being saved, in addition to carried.
The final straw
With their assist, I used to be nonetheless a bit hesitant, however I picked up my items and tried to do one thing completely different for the October try.
Was it about information? What else was I doing through the examination? Sooner or later, when you take care of the information gaps (otherwise you assume you probably did), you must fear about your exam-taking expertise and technique.
I labored extra on my focus and on workouts to maintain myself energetic. I introduced loads of sweets, caffeine, and water and did many, many pushups through the check.
Each time I felt my thoughts was slipping away from me, I might step up, do 20 pushups, stretch myself, wash my face, and are available again to my seat.
In the course of the examination, I used to be consuming vitality drinks, water, espresso, sourworms, and Nutella biscuits. I used to be glad I may carry these items to the testing room!
I additionally supplied from my arsenal to all of the individuals taking the examination with me. Most of them responded to my proposal with incredulous appears to be like and awkward silence. However a few them did get nearer. They acquired Nutella crackers and an vitality drink, some goodies.
This time my angle wasn’t about passing the examination. It was about having fun with the journey, doing my finest, and feeling pleased with how far I’ve come.
This time I didn’t really feel nervousness crawling over my shoulder through the examination, worrying in regards to the end result. I used to be targeted, entertained, and optimistic, all about having fun with myself whereas it occurred.
This time the nervousness wasn’t within the driver’s seat. I felt wonderful, I felt calm (regardless of the irresponsible quantity of caffeine and sugar in my system), and I felt current.
There I used to be, telling Peter the way it was, how I felt, what I noticed. I wasn’t positive if I handed, however I did my finest, and I used to be pleased with it. I checked the outcomes someday after whereas sitting subsequent to my associates. To start with, I couldn’t consider it, I assumed the web site was damaged, and I couldn’t see the everyday “FAIL” I used to be anticipating.
I assumed: “That is kaput, the place is my fail?”
I continued to go looking the underside proper facet of the display screen.
And there it was, on the prime left of the display screen. It wasn’t damaged. It wasn’t flawed. I actually handed, every thing was all proper.
It was the tip of an period, the closure I a lot craved for. I couldn’t do anything however cry. I used to be at all times sufficient, I used to be at all times prepared, and the journey lastly made sense.
CCDE was and can be, for me, probably the most profitable set of failures I’ve ever encountered. And I’m pleased with it, just like the quote attributed to Thomas A. Edison:
I’ve not failed. I’ve simply discovered 10,000 ways in which gained’t work.
—Thomas A. Edison
