CCNA is a foundations certification, and it is a genuinely good one. Take it because you want to understand how systems actually connect. Do not take it expecting it to hand you a destination, because it does not carry that cargo. What it gives you is ground to stand on, and the ground holds.
“When we’re CCNA”
A friend got me into IT. He also got me my first entry-level role. At some point the two of us started joking about "when we're CCNA". Not if. When. It was a running line for years, usually deployed while we were doing something considerably less glamorous than configuring routers.
We put the certification on a pedestal. Nobody handed it to us that way. We built the pedestal ourselves, out of job adverts, forum posts and the observation that the people we looked up to all seemed to have one.
And the phrase was not really a joke. "When we're CCNA" meant doors opening. It meant a better salary, a proper job title, proof that we had made it into the industry for real. For two people at the very start of an IT journey, it was the key to the kingdom. We would not have said it that plainly at the time, but that is exactly what we believed.
Failing the first time
I failed CCNA the first time I sat it. I am not going to dress that up. What I did next matters more. I read the official certification guide cover to cover. Then I read it cover to cover again.
Worth saying here: I thought the official cert guide was brilliant. It covered everything the exam asked for and it explained the material in an order that made sense. Reading a full technical book is not for everyone, and plenty of people learn this material better in labs or videos. But for me it was on the money, and I would not have passed the second attempt without it.
Second time around, I passed. It was the first certification I ever earned, and I was genuinely proud of it. That pride was earned too. I had failed once, gone back through the material properly, and proved to myself that I could close a gap instead of walking around it.
What the pedestal got wrong
The pedestal promised a destination. Reach CCNA and you have arrived somewhere. In reality the certification measures an exam, and the exam measures fundamentals. Subnetting, routing, switching, how traffic moves and where it stops. That knowledge is real and it is useful, but it is a beginning dressed up in a serious-sounding title.
I did not go on to become a network engineer. Not because the certification misled me, but because my career kept pulling me toward other rooms in the building. The fundamentals came with me every time.
Here is the strange part though. In one sense the key to the kingdom worked. The certification set us both on our IT journeys. It gave us fundamentals, confidence and the first proof that we could reach something we had built up in our heads. The kingdom just did not look like the one we had imagined, and mine turned out to be in a different wing of the building entirely.
What it actually bought
Solid foundations is the honest answer, and I have leaned on them in every role since. You cannot troubleshoot what you cannot trace. You cannot secure traffic you do not understand. Every security conversation I have ever been in has eventually touched something I learned while working toward that first pass, and usually something I relearned while working toward the second.
There is also a quieter thing the pedestal got right. The shared goal gave my friend and me a way to push each other. Whatever the certification itself is worth, having somebody in the same chair asking when you are going to book the retake is worth more than most of the study material.
Letting it lapse
After I progressed into different roles I stopped renewing it, and I have not missed it. Cisco states the certification is valid for three years, and renewal is a business decision like any other. If your current work leans on the certification, renew it. If it does not, letting a certification lapse is not a failure or a betrayal of the effort. It is information about where you have gone since. The knowledge does not expire just because the badge does.
Who should take it now
If you are in a support role and keep bumping into networking you do not fully understand, this is one of the best foundations available. One exam, no prerequisites, and material you will still be using a decade later. If you failed it once, book the retake and read the guide properly first. The second pass teaches you something the first fail cannot.
If your target roles never touch networks, choose the certification that matches what those roles actually do. CCNA on a CV does not override evidence of the work you want to be hired for. And if you are weighing up networking against other first moves, I have written separately about why I think networking is still underrated as a foundation for everything that came after it.
Check the current facts
Cisco's exam codes and programme details change over time, so check its current CCNA certification page before booking. The TechWaymark CCNA guide puts the current facts beside the wider career tradeoff, including where CCNA fits if your eventual target is security rather than networking.
