CompTIA Network+ Practice Test (N10-009): Drilling the Five Domains to a Pass
A CompTIA Network+ practice test works best when you drill by domain weight. Here is how to prep the five N10-009 domains and hit the 720 passing score.
A CompTIA Network+ practice test does its real work when you stop treating it as one big quiz and start drilling it by domain. The current exam, N10-009, is a maximum of 90 questions in 90 minutes, and you need 720 on a 100-to-900 scale to pass, per CompTIA. But the five domains are weighted very unevenly, so the candidate who spreads practice time equally across them is wasting effort on light domains and under-drilling the heavy ones.
Here is how to use a full-length N10-009 bank as a diagnostic, then aim your practice where the exam actually puts its points.
Quick takeaways
- N10-009 is the current Network+ exam: a maximum of 90 questions in 90 minutes, multiple-choice plus performance-based questions (PBQs), with 720 to pass on a 100-to-900 scale, per CompTIA.
- The exam has five domains, and Networking Concepts (23%) and Troubleshooting (24%) are the two heaviest. Drill in proportion.
- Subnetting and port-and-protocol questions reward drilling to speed, because the PBQs on those topics eat time.
- Network+ sits between A+ and Security+ on the standard path. If you already hold A+, a focused practice sprint is often enough.
- Use a full-length practice test to diagnose first, then weight your study by domain, then re-test with fresh questions.

What the N10-009 exam actually is
Get the format exact before you shop for practice, per CompTIA:
| Attribute | N10-009 |
|---|---|
| Number of questions | Maximum of 90 |
| Time limit | 90 minutes |
| Question types | Multiple-choice and performance-based (PBQs) |
| Passing score | 720 (on a scale of 100 to 900) |
| Recommended experience | CompTIA A+ and 9 to 12 months of networking experience |
| Version | N10-009 (the current release) |
The passing score is scaled, not a percentage, so there is no "you need X of 90 correct." Aim for a comfortable margin above 720 on full-length practice sets. And note the recommended experience line: CompTIA suggests holding A+ and having roughly a year of hands-on networking before Network+, which is why the standard advice is to take A+ first.
The five domains, and where the points are
CompTIA publishes N10-009 domain weights. This is the map that should drive how you split your practice time.
| N10-009 domain | Exam weight |
|---|---|
| 1.0 Networking Concepts | 23% |
| 2.0 Network Implementation | 20% |
| 3.0 Network Operations | 19% |
| 4.0 Network Security | 14% |
| 5.0 Network Troubleshooting | 24% |
Troubleshooting (24%) and Networking Concepts (23%) together are nearly half the exam. If you have a fixed number of practice hours, that is where most of them belong. Network Security is the lightest domain at 14 percent, which surprises people who assume it overlaps heavily with Security+. It does not; Network+ security is narrow and foundational, and over-studying it steals time from the two big domains.
The two topics worth drilling to speed
Most Network+ topics you either know or you look up. Two are different, because they are calculation-and-recall tasks that the exam times you on:
- Subnetting. Converting between CIDR notation, subnet masks, host counts, and network ranges. Under exam time pressure, slow subnetting is a score-killer. Drill it until you can do the common conversions without a scratchpad, then keep drilling until it is fast.
- Ports and protocols. The exam expects instant recall of common port numbers and what runs on them (HTTP 80, HTTPS 443, SSH 22, and the rest). These are pure memorization, and flashcard-style repetition until recall is automatic is exactly the right method here.
Everything else is best learned through scenario questions with rationales. These two are the exceptions where speed drilling pays off directly, because the PBQs built on them punish hesitation.
How to use a Network+ practice test
The loop is the same disciplined diagnostic approach that works for every CompTIA exam.
- Take one full-length timed test. Ninety questions, real clock, PBQs included. Record your starting score and, more importantly, your per-domain breakdown.
- Weight study by domain. Pour time into Troubleshooting and Networking Concepts first. Do not equalize across all five.
- Speed-drill subnetting and ports separately. Treat these as their own timed exercises until they are automatic.
- Read rationales on every miss. For the conceptual and troubleshooting questions, the explanation of why the right answer is right is the real lesson.
- Re-test with fresh questions, confirm you are comfortably clear of 720, then book the exam.
Network+ after A+, or straight to Security+
Two common questions decide where Network+ sits in your plan.
If you hold A+ already, Network+ is a natural next step and a focused practice sprint of one to three weeks is often enough, because A+ Core 1 already introduced networking basics. If you are brand new to IT, take A+ first; jumping straight to Network+ without the A+ hardware-and-networking foundation makes the concepts domain much harder.
If your only goal is a cybersecurity job, some people debate skipping Network+ and going A+ to Security+ directly. That works for the certification, but the networking knowledge Network+ builds is genuinely load-bearing for security work, so skipping it tends to catch up with you on the job even if it does not on the exam.
FAQ
How many questions are on the Network+ N10-009 exam?
A maximum of 90 questions in 90 minutes, per CompTIA, mixing multiple-choice and performance-based questions (PBQs). You will not always see exactly 90; that is the ceiling.
What is the passing score for Network+?
720 on a scale of 100 to 900, per CompTIA. It is a scaled score, not a raw percentage, so practice to a clear margin above 720 on full-length tests rather than aiming for a specific number correct.
Should I take A+ before Network+?
CompTIA recommends holding A+ and having 9 to 12 months of networking experience before Network+. If you already have A+, Network+ is a manageable next step. Complete beginners generally find A+ first makes Network+ much easier.
Is Network+ security the same as Security+?
No. The Network Security domain is only 14 percent of N10-009 and covers narrow, foundational network-security topics. Security+ is a separate, deeper cybersecurity certification. Do not over-study the security domain at the expense of the two heaviest domains.
What is the hardest part of the Network+ exam?
For most people, subnetting under time pressure and the troubleshooting domain (24 percent of the exam). Both reward drilling: subnetting to speed, and troubleshooting through scenario questions with rationales that teach the diagnostic method.
Can I use a free Network+ practice test?
Yes, as a readiness check. Free sets place you across the domains but tend to be light on PBQs and rationales. A full-length bank with explanations is what closes gaps once a free test shows you have them.
