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 virtually at all times asking “why?” each time I obtained one thing defined or instructed, which might drive a lot of the adults to madness after a few hours with me.
My mother, in an try and get this matter solved, gave me a e book known as “El porqué de las cosas,” which roughly interprets to English as “The why of the issues.”
I might spend hours studying and asking much more questions. It was an infinite loop I loved as a (un)naturally curious child. To my shock, the e book had a number of volumes explaining issues all of us marvel about, however not many people have the drive to search for, 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 bear in mind Microsoft Encarta?), novels (Potterhead right here!), tales, newspapers, and my profession area: IT.
I began tweaking my very own laptop when it felt gradual, as I wished 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 probabilities have been infinite!
Touching and troubleshooting techniques, putting in units, and connecting cables and printers (units from hell!) grew to become pure, and I began making a residing out of it after I was 16 years outdated.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 grew to become a community engineer, the urge to know the way issues labored simply made it pleasurable and compelling. There was an invisible world to us underneath cables, numbers, and blinking lights. I discovered an infinite curiosity properly (or hose) I might drink from every single day.
Why CCDE?
Round 2016, after a number of years as a community help engineer, I made a decision to review community design. However why? By that point, I labored with many engineers and will see a distinction between them. Some have been glad to implement issues and see them working, generally with out them being utterly clear to them. And another engineers, although, knew very properly how issues labored and why the modifications have been being launched. They’d a distinct perspective.
That instantly caught my consideration; I wished to know the explanations behind issues. I was curious! At the moment, the CCDE group was rising and everyone was so vibrant and welcoming that I obtained lured into it. I made a decision that although it might be a tough factor to do, I wished to review community design.
You’re normally instructed that CCDE is a certification for skilled engineers and, given the quantity of information required, you must have not less than one CCIE earlier than making an attempt it. It initially discouraged me—till I spoke with folks like Elaine Lopes, Daniel Dib, Jeremy Filiben, Mark Holm, and Andre Azevedo. They assured me you that don’t want a CCIE to try the examination, however you do want the data 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 occasions: “You have to be on the similar degree. Make expertise your second nature, and perceive issues all the way down to the bone.”
That 12 months, I began finding out and assessing myself truthfully, in search of areas to enhance. I aimed for CCDE and the huge data it might require.
I initially took the CCDP* examination to gauge myself, which lined not solely fundamentals but additionally greatest practices; what was beneficial given sure circumstances. After passing, I bear in mind feeling energized and prepared for extra.
Again then, I assumed: “What if I strive 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 finding out to move the CCDE written examination. The primary one was my means of gauging myself, whereas the second failure felt excruciatingly shut. Lastly, my third try was a candy move.
The CCDEv2 written examination was a beast. It primarily mixed Enterprise and Service Supplier subjects, whereas additionally including some safety as properly, making it a mighty difficult examination by itself.
Was all my finding out sufficient to move 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 concerning the examination; the fashion of the take a look at, the quantity of knowledge, 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 middle 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 data, extra studying, extra expertise.
Typically, that meant that I didn’t perceive a specific expertise properly sufficient. Different occasions, that meant I had missed said necessities or constraints or was not capable of focus for the whole time of the take a look at (8 hours).
This occurred twice in 2018, in Might and November. On each events, it was a FAIL for me.
After getting overwhelmed twice, I continued making an attempt. Out and in, it was powerful to get on my ft once more.
In between my makes an attempt in 2018 and 2019, I additionally took different exams to check my data and get myself nearer to the “CCIE-level” data I wanted earlier than I confronted the beast as soon as extra.
I used to be capable of move the CCIE R&S** and Service Supplier exams whereas getting ready for the following accessible 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 occasions, 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 considered taking a break earlier than dealing with the examination once more. I didn’t know, nonetheless, that my break can be all that lengthy.
Taking a break
Between 2019 and 2022, rather a lot occurred in my life. (And doubtless 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 capable of 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 suppose 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 the whole examination.
- I introduced preconceived notions into the examination.
- No one does that in the actual world!
- I mustn’t have second-guessed myself…
- God, I hate tables!
Every a type of makes an attempt teaches you one thing, however you must concentrate. 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 until you brace your self.
In my case, I used to be not capable of see the forest due to the bushes. Though it sounds humorous, it was the case. I used to be an issue as an alternative of zooming out and looking out 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 Heart, extra enterprise, extra Cloud, and extra Wi-fi!
Earlier than persevering with with my story after the break, we might discuss which issues are necessary to your CCDE journey. Don’t fear. We will likely be shedding some tears in a bit.
What do it’s good to move the examination?
Research group and associates – AKA group
Your research group might be the important thing useful resource it’s good to move. The extra views you get, the higher your technical arsenal will likely be when dealing with the examination.
Throughout my CCDE journey, I had the luxurious of finding out with folks like Mike McPhee, Jason Beltrame, Bruno Wollman, Fareed Fakoor, Remington Free, Ronald Lopez, Anti Sourdi, Freerk Terpstra, Nicolas Vallet and Fabian Beck. All of them are good engineers/architects, they usually all taught me one thing alongside the way in which. We shared suggestions and data, had periods to show others about what we have been good at, and naturally, made stunning bonds within the course of.
On prime of that, I had great associates who weren’t finding out to take the CCDE examination however have been supporting me and educating me issues (educate me your secrets and techniques, grasp!) or supporting me as an individual, as a good friend: folks 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 research buddies, folks to debate with, folks keen to pay attention, a ground that might help me… a group. With out them, I’d not have handed it. This late success was because of 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 stored me on observe, pulled my ears when wanted, and hugged me laborious sufficient to drag my items collectively once more after I couldn’t do it myself.
Know your self
One other necessary a part of your journey is to know your self. This may sound like a cliché for a lot of, however it’s tremendously necessary, or not less than it was for me.
The CCDE examination is totally different from some other CCIE examination. It doesn’t depend on muscle reminiscence or quick typing. You will need to contemplate every choice, learn each doc, and consider each selection. It’s an 8-hour-long studying comprehension examination with technical and enterprise subjects. Your psychological state is paramount.
- Are you aware once you research one of the best? Is it throughout 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 finding out?
- What about 4-hour or 2-hour blocks?
- How good is your focus? (I get distracted simply.)
- How do you address anxiousness?
- 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 concerning the examination?
- How do you are feeling when getting into, leaving, and throughout the examination?
- Anxious?
- Nervous?
- Scared?
- Relaxed?
All this stuff have been necessary for me, and I want I’d have considered them beforehand. I needed to be taught to contemplate them after each failed try.
Initially, my drivers after I began all this have been: ambition, delight (relatively hubris), and worry. I wished to get as excessive as doable, to be actually good at one thing, to be acknowledged, to close up each mouth that stated (there have been many) that I couldn’t make it or it was too laborious and I used to be going to fail, and likewise, my worry of lacking out (FOMO).
A beautiful tune about that is Vienna, by Billy Joel.
Over time I discovered (because of my expensive good friend Peter Palúch, my psychologist, and a ridiculous quantity of introspection) that though my earlier drivers helped me to remain motivated and go away the nation, I used to be not going to make it any additional with unfavourable feelings, they’d chew me up ultimately. What can be higher? Discovering constructive motivation!
I did my greatest to cease evaluating myself with others and solely examine myself with David from the previous. All of us have failures, everyone knows one thing anyone else doesn’t, and all of us can be taught one thing from others. Even the folks we don’t like can educate us one thing.
I began wanting on the journey in addition to the purpose. 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 pondering, “I received’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 greatest to cease worrying concerning the examination’s consequence. In spite of everything, I had already failed a number of occasions. Will it burn extra? Perhaps a bit. Will or not it’s a disaster? Not likely. Simply choose up your items, regroup, and deal with it once more. The examination is already nerve-racking sufficient, and worrying about failing earlier than taking it is going to 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’ve gotten 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 greatest throughout the examination. Go or fail, it will likely be one of the best of me.
I didn’t know if I handed, and I used to be about to examine the following accessible date for the examination. Little did I do know that I’d move 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 observe
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 wonderful.
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 at last be taught properly: QoS, and multicast.
Now, the examination was supplied in Brussels like some other CCIE examination, so I didn’t need to juggle balls to e book an examination in a Pearson Skilled Heart in Frankfurt or Madrid. I might go to the Cisco workplace in Brussels like everyone else!
Additionally, a number of associates work there, so it’s a acquainted place for me.
In the midst of ten months, I visited Brussels 4 occasions. Each time, I used to be welcomed by my expensive 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 totally different: the brand new engine, the brand new situations, the fashion, the expertise. And, God, I did.
I got here out of the examination wanting like a fish in a fridge: eyes and mouth large 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 part was unfavourable!)
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 state of affairs and defined it to us intimately.
I went once more in February with loads of hopes, nonetheless, it wasn’t but my time. Despite the fact 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 infinite listing!
I stored an inventory of subjects I felt not sure about and added extra after each try. The listing began enormous 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 finding out. My Cisco Reside 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 periods 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 relatively 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 greatest and felt prepared for the examination. Proper after Cisco Reside US, I headed again to Brussels for my third try at CCDEv3.
I labored on my data, 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 virtually positive.
I got here out hoping for one of the best and was shot down by a FAIL. It was, by far, essentially 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 capable of conquer such a titanic purpose 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 after 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, they usually gave me extra encouragement than I might have requested for.
I felt like Spiderman (Tobey Maguire) getting carried over their heads after saving the folks on the prepare 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 totally different for the October try.
Was it about data? What else was I doing throughout the examination? In some unspecified time in the future, when you take care of the data gaps (otherwise you suppose you probably did), you must fear about your exam-taking expertise and technique.
I labored extra on my focus and on workout routines to maintain myself energetic. I introduced loads of sweets, caffeine, and water and did many, many pushups throughout the take a look at.
Each time I felt my thoughts was slipping away from me, I’d step up, do 20 pushups, stretch myself, wash my face, and are available again to my seat.
Throughout the examination, I used to be consuming vitality drinks, water, espresso, sourworms, and Nutella biscuits. I used to be glad I might carry this stuff to the testing room!
I additionally supplied from my arsenal to all of the folks taking the examination with me. Most of them responded to my proposal with incredulous appears and awkward silence. However a few them did get nearer. They obtained Nutella crackers and an vitality drink, some candies.
This time my angle wasn’t about passing the examination. It was about having fun with the trip, doing my greatest, and feeling happy with how far I’ve come.
This time I didn’t really feel anxiousness crawling over my shoulder throughout the examination, worrying concerning the end result. I used to be targeted, entertained, and constructive, all about having fun with myself whereas it occurred.
This time the anxiousness wasn’t within the driver’s seat. I felt tremendous, 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 greatest, and I used to be happy with it. I checked the outcomes someday after whereas sitting subsequent to my associates. To start with, I couldn’t imagine 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 unsuitable. I actually handed, every part was all proper.
It was the top 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 will likely be, for me, essentially the most profitable set of failures I’ve ever encountered. And I’m happy with it, just like the quote attributed to Thomas A. Edison:
I’ve not failed. I’ve simply discovered 10,000 ways in which received’t work.
—Thomas A. Edison
