The practice exam closest to the real CCNA is the one written by the people who write the real CCNA: the official Cisco and Pearson practice tests. The practice exam that best prepares you to pass it is Boson ExSim‑Max, which is deliberately harder than the real thing. Those are two different questions and the answers point at two different products.
If you want to know what exam day feels like, use the official tests. If you want to be ready for it, use Boson. Most candidates who pass comfortably have used both, in that order of importance. What follows is the short version of a longer ranking of every CCNA practice exam worth considering, focused on the one question that ranking does not directly answer.
Which CCNA Practice Exam Is Most Realistic?
The official Cisco and Pearson practice tests, at around $50, and it is not really a contest. They are produced by the same organisation that writes the exam, which means phrasing, answer construction and difficulty calibration all come from the source rather than from someone reverse‑engineering it.
What they are less good at is teaching. Realistic difficulty means you get a fair read on where you stand, and a fair read is not the same as a study tool.
| Product | Cost | Difficulty vs real exam | Explanations |
|---|---|---|---|
| Boson ExSim‑Max | Around $99, $149 with NetSim | Harder, by design | Detailed, the actual product |
| Cisco U. / Pearson official | Around $50 | Closest match | Present, lighter |
| Udemy practice tests | Around $15 to $25, often $10 on sale | Easier | Variable by author |
| MeasureUp | Around $99 | Reasonable | Adequate |
| Free question banks | Free | Much easier | Usually none |
Why Is Boson Harder Than the Real Exam?
Because it is built that way on purpose, and that design choice is the reason it works. Boson writes each exam to match or exceed real exam difficulty, on the theory that a candidate comfortable at a harder level walks into the real thing with margin.
The practical effect is that first scores are demoralising and shouldn’t be. Most candidates land between 55 and 70 on a first untimed run, even after finishing a full video course. That is normal. What matters is whether the second exam, two weeks later, is meaningfully higher after reading every explanation from the first.
Are Free CCNA Practice Tests Worth Using?
At the very beginning, yes. At the end, no.
Free banks are useful in week one, when you have never seen a Cisco‑style question and any exposure to the phrasing helps. Their problem is that they recycle shallow question sets and rarely explain their answers, so they train you to recognise specific questions rather than to reason about new ones.
There is a failure mode worth naming: averaging high on free sites and walking into the exam confident. It is a common story, and a pattern we have seen enough times to treat as a warning rather than an anecdote. A high free‑site average measures familiarity with that site’s question bank.
What Score Should You Get Before Booking the Exam?
On Boson, 85 percent or higher in simulation mode, on an exam you have not seen before. Simulation mode means timed, explanations hidden, nothing looked up.
Some people will say 80 is enough, and it might be. The extra margin covers what no practice tool simulates: nerves, an unfamiliar room, and the fact that you cannot return to a question once you have moved past it. That last constraint changes how the exam feels more than most people expect.
Note that Cisco does not publish a fixed passing score for the 200‑301. Scores are scaled, and the widely cited 825 out of 1000 figure comes from older Cisco exams rather than current published policy. Practice exam percentages are a readiness signal, not a conversion to an official threshold.
How Should You Use Practice Exams Without Wasting Them?
The exams are a limited resource. Five exams burned during the learning phase leave you nothing for the final stretch, and a question you have already seen tests memory rather than reasoning.
- Finish learning the blueprint first, from a course and labs.
- Take the first exam untimed and read every explanation, including for questions you answered correctly.
- Go back to whatever topics the explanations exposed. This is the actual study step.
- Two weeks later, take a fresh exam in simulation mode.
- Repeat until a fresh exam clears 85 percent under timed conditions.
The explanations are the product. Treating the exams as scored quizzes rather than as a study text you unlock by being wrong is the most common way to own a good tool and get little from it.
Do Practice Exams Cover the Lab Questions?
Partially, and this is the honest gap. The CCNA includes lab simulations where you type real commands, and no practice exam reproduces that interface exactly.
Configuration skill comes from Packet Tracer, a simulator or real gear. What practice exams give you is the reasoning and the clock. It is worth knowing which question formats the CCNA actually uses before you judge a practice product on realism. For the interface itself, Cisco publishes exam tutorials showing how the question types behave, and ten minutes there before test day removes a surprise you do not want on the day.
Frequently Asked Questions
Which practice exam is closest to the real CCNA?
The official Cisco and Pearson practice tests, written by the same organisation that writes the exam. Boson is closer in style than anything else third party, but harder on purpose.
Is Boson worth $99 when Udemy tests cost $15?
Yes, for the explanations. Cheaper tests will tell you an answer was wrong. Boson tells you why the wrong one was attractive and why the right one wins in that specific scenario, which is the skill the exam is testing.
How many questions does Boson include?
Five full‑length practice exams built on roughly 370 questions in the current CCNA product. Older reviews citing three exams predate an expansion and are out of date.
Should I buy more than one practice exam product?
Most people do not need to. Boson for preparation plus the official tests for a realistic final check is plenty. Buying a third is usually procrastination wearing a productive disguise.
Can I pass using only free practice questions?
Possible, uncommon. Free banks are shallow and rarely explained, so they build recognition rather than reasoning. They are best treated as a starting point, not a readiness check.
Does the February 2027 blueprint change affect practice exams?
It will. The 200‑301 v2.0 blueprint goes live February 3, 2027, with February 2, 2027 the last day for v1.1. If you are testing after that, confirm any practice product targets v2.0 before buying, and check it against the current Cisco exam topics.
How long before the exam should I start practice tests?
Four to six weeks, after the blueprint is learned. Earlier than that and you spend the exams while you are still learning the material they are meant to test.
