How Hard Is Network+? Where the N10-009 Exam Costs You Points

How hard is Network+? For someone with some hands-on IT time, it is a fair exam with a fast clock. The content sits at an early-career level, but the N10-009 asks you to apply it, not just recite it: up to 90 questions in 90 minutes, a mix of multiple-choice and performance-based items, and a passing score of 720 on a scale of 100 to 900.

Most people who find it hard lose points in a few predictable places: subnetting math done slowly or off by one, the troubleshooting methodology taken out of order, and scenario questions where they pick the answer that sounds busiest. If you are still deciding whether to sit it, what the Network+ certification is covers the credential itself. This post is about the exam.

What does a 720 passing score mean?

CompTIA states the passing score as 720 on a scale of 100 to 900. That is a scaled score, and CompTIA does not publish the formula that turns your answers into it. So 720 is not "72% correct" or "80% correct", and any calculator that claims to convert it is guessing.

What you can take from the number is simpler. You need a solid result across the whole exam, and you cannot plan to pass by counting how many questions you think you got right. Clear 720 by being competent in all five domains, and leave the arithmetic out of the exam room.

Does CompTIA publish a Network+ pass rate?

No. CompTIA does not publish a pass rate for Network+, and it does not publish how many people hold the certification. Any percentage you see on a forum or a training site is someone's estimate, not CompTIA's figure.

That matters for how you judge difficulty. Without an official rate, the honest way to size the exam is by its structure: the time limit, the item types and where the domain weight sits. Those are known, and they explain most of what candidates report.

Why does 90 questions in 90 minutes feel so tight?

The exam has a maximum of 90 questions and a 90-minute limit. On paper that is a minute per question. In practice it is less even than that, because the questions do not take equal time.

A port-number recall item can take fifteen seconds. A scenario that asks you to read a subnet plan, or work out which of four show outputs points to the fault, can take several minutes. Performance-based items ask you to do something rather than pick a letter, and they eat the clock fastest.

My opinion: the clock, not the content, is what makes Network+ feel hard to most first-time candidates. People who know the material well still run short because they did every practice question untimed. Do at least some of your practice in timed blocks at under a minute per item, and get used to moving on when a question stalls you.

CompTIA does not say how many performance-based questions appear on a given exam, so do not plan around a number you read somewhere. Plan to be fast on the recall items so the scenario items have room.

Why does subnetting cost so many points?

Objective 1.7 reads "Given a scenario, use appropriate IPv4 network addressing". It sits in Networking Concepts, the second-largest domain at 23%, and in my view it is the topic most worth fearing early. The math itself is not advanced. It is binary place values, prefix lengths and subtraction. The difficulty is doing it correctly and quickly while the timer runs.

The book's chapter on 1.7 lists the off-by-one errors that cost the most:

• Counting the network ID as a usable host. It is not.

• Counting the broadcast address as a usable host. It is always the last address in the subnet, and it is not usable either.

• Applying "subtract two" to a /31. On a point-to-point link between routers, a /31 uses both addresses (RFC 3021). A /32 is a route to a single host.

A question about a router interconnect that offers "0 usable hosts" for a /31 is testing exactly that last rule. If subnetting is slow for you today, it is the single best place to put early study time, because the same skill shows up again in addressing, routing and troubleshooting scenarios.

How hard is the Network Troubleshooting domain?

Network Troubleshooting is the largest domain on N10-009 at 24%. Four of its five objectives begin "Given a scenario", so most of it is applied: cabling and physical interface faults, network service faults, performance problems, and choosing the right tool or protocol. The fifth objective, 5.1, is the troubleshooting methodology, and that is where a lot of easy points get thrown away.

CompTIA's methodology has seven steps in a fixed order. Identify the problem. Establish a theory of probable cause. Test the theory. Establish a plan of action and identify potential effects. Implement the solution or escalate. Verify full system functionality and implement preventive measures. Document findings, actions, outcomes and lessons learned.

The trap is that real technicians often skip steps, and the exam marks skipping as wrong. Here is a question in the style the exam uses:

A technician suspects a user's connectivity problem is caused by a misconfigured switch port. The technician checks the port configuration and confirms the theory. What should the technician do NEXT?

A. Change the port configuration to fix the problem

B. Establish a plan of action and identify potential effects

C. Document the findings and lessons learned

D. Verify full system functionality

The answer is B. A confirmed theory tells you what is wrong, not how to fix it safely. The next step is to plan the change and think about what else it could affect, such as other devices on that switch or a change window. Option A is the tempting one, and it is the most common process error the book's methodology chapter describes: jumping straight from confirmation to implementation. Documentation (C) is the last step, not the next one. Verifying functionality (D) only makes sense after a fix has been made.

The scenario objectives in this domain have their own traps, and they share a pattern: the obvious tool or the obvious culprit is wrong.

• Blaming DNS when routing is broken. If nslookup returns the right address but the application still cannot connect, name resolution worked. The packet is being dropped somewhere in the path, so check routing and the default gateway next.

• Trusting a good ping for voice problems. Choppy VoIP with a 20 ms average round-trip time does not mean the network is fine. Ping averages hide jitter, which needs a tool that reports per-packet delay variation.

• Replacing a cable that tested clean. CRC errors plus late collisions on a cable that passes the tester point to a duplex mismatch, not the cable.

• Using a toner to find a break. A toner and probe identifies which cable you are holding. A TDR tells you where on that cable the fault is.

For how the five domains fit together and why Troubleshooting edges out Networking Concepts, see the Network+ domains explained.

Which smaller traps add up?

None of these is hard on its own. Together, under time pressure, they account for a lot of near-misses. Each one is a pair of similar terms where the exam rewards knowing the deciding detail.

Switching has two more that the book flags for scenario questions in objective 2.2. A newly created VLAN with no connectivity across switches is usually missing from a trunk's allowed VLAN list. And a native VLAN mismatch between the two ends of a trunk produces intermittent problems on one VLAN that look like something else.

How hard is Network+ for your background?

CompTIA's recommended background, A+ plus 9 to 12 months in a junior network role, is not an entry requirement (the Network+ requirements post covers what CompTIA does and does not ask for). It is a good guide to who struggles, though.

It tends to be harder for career changers with no networking exposure, who meet subnetting, port numbers and CLI output all at once. It is also harder for people who studied from flashcards alone. Recall is enough for some items, but the scenario objectives ask you to read a situation and choose an action, and recall does not train that.

It tends to be easier for help desk and support technicians who already run ping, traceroute and ipconfig daily and have patched a cable or two. They have seen the symptoms before. Their risk runs the other way: they answer the way their own shop does it, skip methodology steps, or accept "Telnet is fine on a private network" reasoning that the exam rejects.

Holding A+ helps with the hardware and cabling vocabulary. It does not cover subnetting or routing in depth, so A+ holders still need real time on Domains 1 and 2.

What fixes the hard parts fastest?

Preparation follows directly from where the points go.

Get subnetting fast before anything else, to the point where a /27 or a /22 gives up its network ID, broadcast and usable range in seconds. Learn the seven methodology steps word for word and in order, then practice "what should you do NEXT" questions against them.

Weight your hours toward Domains 5 and 1, which together make up 47% of the exam, and read explanations for the wrong options as carefully as for the right one. The CompTIA Network+ N10-009 Study Guide 2026 includes worked, step-by-step drills for each of the ten "Given a scenario" objectives, with every practice answer explained, for exactly that reason. The Network+ study plan turns the weights into a schedule, and the Network+ practice questions walkthrough works through several items in full.

If the first attempt does not go your way, CompTIA lets you retake right away the second time. A third attempt, and any after that, needs at least 14 calendar days of waiting, and you pay the exam price each time. The Network+ exam cost breakdown covers the voucher and retake options.

FAQ

Is Network+ harder than A+?

For most people it is the harder of the two, mainly because of subnetting and the scenario-based troubleshooting items, which ask you to diagnose rather than identify. CompTIA itself positions A+ as the recommended starting point before Network+. The two exams cover different ground, so passing A+ does not prepare you for the IP addressing and routing material.

Is 720 out of 900 the same as 80%?

No. The score is on a scale of 100 to 900, and CompTIA does not publish how raw answers convert to that scale. Do not try to translate 720 into a percentage of questions correct. Aim to be solid across all five domains instead.

What is the Network+ pass rate?

CompTIA does not publish a pass rate for Network+. Figures you see online are unofficial estimates. A more reliable way to judge difficulty is the exam's structure: up to 90 questions in 90 minutes, with the largest share of weight on troubleshooting.

What is the hardest topic on Network+?

For most candidates it is subnetting under time pressure, from objective 1.7, because the same skill comes back in routing and troubleshooting scenarios. Close behind is the troubleshooting methodology, where knowing the steps is easy and keeping them in CompTIA's order under a tempting answer is not.

Getting ready for N10-009? The CompTIA Network+ N10-009 Study Guide 2026 gives each of the 25 exam objectives its own chapter, with worked drills for the scenario objectives and 164 practice questions across five domain banks, every answer explained.
