Last spring, about three weeks into my CCNA study grind, I did something I’m not proud of. I opened up ChatGPT and typed: “Give me 20 CCNA practice questions on OSPF with detailed explanations.” Then I sat back, practiced for two hours, scored myself a 95%, and went to bed feeling great about my progress.
A week later, I took a real practice exam and got absolutely humiliated on OSPF.
That experience taught me more about AI-generated exam questions than any article probably could. But I’ve spent enough time experimenting with this approach since then that I think there’s a more nuanced story worth telling. Because AI-generated questions aren’t worthless. They’re just not what most people think they are.
What AI Actually Gets Right
Let me start with the genuine upside, because it’s real. If you’re early in your studies and trying to get reps on a concept you just learned, AI can generate questions faster than anything else on the market. You can type “give me 10 beginner questions on STP port states” and have a quiz in 30 seconds. There’s no subscription to manage, no waiting, no hunting through a question bank hoping the topic comes up.
The sheer customizability is genuinely useful. Struggling with a specific sub-topic, like OSPF neighbor states versus STP states and you keep confusing the two? Ask an AI to write questions that specifically target the distinction. It’ll do it. No dedicated practice tool gives you that kind of surgical control over content.
AI also tends to be decent at explaining foundational concepts in plain language. If you get a question wrong and ask for an explanation, you’ll usually get something coherent. For someone who’s brand new and just needs a concept explained three different ways until it clicks, that’s a real value. I still remember using it to understand the binary logic behind subnet masks when I was first getting started, before I eventually dug into the deeper subnetting practice that actually made it stick.
Where It Falls Apart
Here’s the problem. The CCNA exam is not testing whether you understand concepts. It’s testing whether you can think through a scenario the way Cisco wants you to think through it. Those are very different skills, and AI-generated questions almost never develop the second one.
The questions tend to be straightforward in a way the real exam isn’t. AI writes things like: “What does OSPF stand for?” or “Which command shows the routing table?” That’s not an exam question. That’s a flashcard. The real exam gives you a scenario with a partially configured network, tells you a symptom, lists six possible causes that all sound vaguely plausible, and asks you to pick the three that apply. AI rarely recreates that structure, and when it tries, it usually gets the wrong answers mixed up with the right ones in ways that don’t actually reflect how Cisco designs distractors.
The accuracy problem is significant. I’ve caught AI tools generating questions with flat-out wrong answers. Not subtle errors. Wrong answers stated with total confidence. Once, I got a question about EIGRP metric calculation where the provided explanation had the formula partially backwards. If I’d been new enough to trust it, I would have learned the wrong thing entirely. There’s no editorial process behind these questions. Nobody who has passed the CCNA reviewed them. They’re generated on the fly and handed to you.
The false confidence issue is probably the most dangerous part. Because AI questions are generally easier than the real thing, you’ll score higher on them. You study, you quiz yourself, you score 90%, you feel ready. Then you sit down for the actual exam and get hit with scenario-based questions that require three interconnected concepts to unpack simultaneously, and the confidence evaporates fast. I’ve heard this story from more than one person who wondered why they studied so hard and still came up short. The practice material they used wasn’t calibrated to the actual difficulty of what they were preparing for.
There’s also the format problem. The CCNA includes simulation questions where you have to actually configure a device in a command-line interface. AI can write questions about configuration, but it can’t simulate the experience of typing commands under time pressure and getting error messages you have to interpret. That’s a skill you have to build somewhere else.
The Underlying Issue With “Free” Practice Questions
I want to be honest about something. Part of the appeal of AI questions is the price. Zero dollars is a compelling number. And I completely understand the impulse. Exam fees are expensive, courses cost money, and the whole certification process adds up fast.
But there’s a real cost to practicing with inaccurate or calibration-wrong material. You spend time developing false confidence instead of identifying your actual weak spots. You practice the wrong mental model for how the exam questions are structured. And then you fail, or you pass with a lower score than you should have, because the tool you used wasn’t built to prepare you for this specific exam.
Purpose-built tools like Boson ExamSim exist for exactly this reason. The questions are written and reviewed by people who understand Cisco’s exam methodology. The difficulty is calibrated intentionally. The explanations are detailed and accurate. It costs money, but it costs money because that quality was built by people doing real work. I wrote about my experience with it at length in my Boson review — the short version is that it’s the tool that actually got me certified after failing on my own.
That’s not a knock on AI tools. It’s just an honest comparison of what each one is built to do.
How I Actually Use AI in My Study Routine Now
I didn’t stop using AI for studying after my OSPF humiliation. I just recalibrated how I use it.
It’s good for concept clarification. When I’m reading through a section in the glossary or studying from a video course and something doesn’t click, I’ll ask an AI to explain it a different way. That conversation format can unstick a concept faster than re-reading the same paragraph three times.
It’s decent for low-stakes recall drills. If I want to make sure I remember the basic facts around something I just learned, a quick five-question AI quiz before moving on isn’t harmful. The risk comes when people treat this as real exam prep rather than what it actually is: a cheap way to do a knowledge check on fundamentals you’re actively studying.
It’s useful for generating lab scenario ideas. “Give me five VLAN troubleshooting scenarios to lab in Packet Tracer” is a totally reasonable AI prompt. You’re not trusting the AI to evaluate whether you got it right. You’re using it as a creative brainstorming partner to build your own practice situations.
Where I don’t use it anymore: the final stretch before an exam. Once I’m in exam-prep mode, the last thing I want is questions that don’t match the real difficulty and format. That’s when purpose-built practice exams matter most, because that’s when calibration matters most.
The Verdict
AI-generated exam questions are a legitimate supplementary tool for early-stage studying. They’re fast, flexible, and free, which makes them genuinely useful for building a basic understanding of concepts before you start treating practice exams seriously.
They’re a bad primary study strategy for anyone who actually wants to pass. The questions are too easy, the accuracy isn’t guaranteed, and they don’t teach you to think the way Cisco expects. Using them as your main practice source is like training for a marathon on a treadmill that only goes three miles per hour. You’ll feel like you’re working, but you won’t be ready for race day.
The CCNA is a hard exam. It deserves tools built specifically for it. Use AI for what it’s good at, and save the serious prep work for tools that take the exam as seriously as you do.
