Is Network+ N10-009 Hard? An Honest Look

The short answer

Network+ N10-009 is a moderate exam: broader than it is deep. Most people who struggle do so because of the range of topics, the subnetting math and the performance-based questions, not because any single idea is extreme. If you already work with networks, it can feel manageable. If you are new to IT, expect to study for longer.

Difficulty is personal, so no one can promise a result. What you can do is measure yourself, and this page shows how.

What makes it feel hard

Breadth. The exam objectives cover everything from cable connectors to SD-WAN, DNS records, wireless encryption, disaster recovery and attack types. Each topic alone is learnable. Holding all of them at once is the work.

Look-alike concepts. Many questions put two close ideas side by side. RPO or RTO. IDS or IPS. A reservation or an exclusion. A rogue AP or an evil twin. The right answer usually depends on one detail in the scenario.

Numbers on demand. You need common port numbers, subnet sizes and basic IPv6 forms ready in your head. There is nothing to look up in the exam.

Performance-based questions. CompTIA lists performance-based questions alongside multiple-choice. They ask you to do something, not to pick a letter, and they usually take more time.

Time. Up to 90 questions in 90 minutes leaves little spare time. If a few questions eat several minutes, the rest has to go faster.

Scenario reading. Many stems are short stories with a detail that rules out the second-best answer, such as a budget limit, a legacy device or a no-downtime rule.

Who usually finds it easier

  • People who already do network support, such as help desk staff who reset ports, check DHCP and read switch output.
  • People who finished A+ recently and kept the habit of studying.
  • People who build things at home: VLANs on a managed switch, a lab with virtual machines, a packet capture now and then.

Who usually finds it harder

  • People who have worked only with software and have never touched a switch, router or access point configuration.
  • People who rely on one video course and never practice in a timed setting.
  • People who skip subnetting and hope it will not come up. It will.
  • People who study material for N10-008 and miss the topics that were added.

Common reasons people fail

  1. Learning by reading only. Recognizing a term on a page is not the same as picking it among four lookalikes under time pressure.
  2. Weak subnetting. A dozen lost points can come from not being fast with CIDR.
  3. Ignoring troubleshooting. It is the biggest domain at 24%. Knowing the method and which tool answers which question matters.
  4. Mixing up ports and protocols. A small table, reviewed daily, fixes most of this.
  5. Poor time use. Spending too long on early questions or on a performance-based task.
  6. Skipping weak domains. A strong score in security does not make up for a weak one in operations or implementation.
  7. Using outdated material. Old books skip SD-WAN, VXLAN, IaC, SASE and zero trust.

How to judge your readiness

Use evidence, not feelings.

  • Score consistently above your target across several full-length practice sets, not on one lucky attempt. Set a target comfortably above where you think the passing line is, because practice material varies and the real scale is not a simple percentage.
  • Check every domain. If one domain trails the others by a wide margin, fix that first.
  • Track your repeat misses. If the same ten concepts keep costing you, you are not ready, however good the average looks.
  • Time yourself. Finish a full set within the limit with a few minutes to review flagged items.
  • Explain, don’t just recognize. Pick five topics at random and explain each to someone in two minutes. If you stall, review.
  • Do a hands-on check. Run ping, traceroute, nslookup, dig, netstat and arp on a real machine and read the output out loud.

Our study plan puts these checks into a schedule. The how to study guide covers general habits.

A fair expectation

Steady, structured study is the best preparation. If a first attempt does not go well, CompTIA’s retake rules allow another try. You can retake right after a first failed attempt, but each attempt needs a new fee, so preparation pays for itself. Treat a practice score as a signal, never as a promise.

FAQ

Is Network+ harder than A+?

Many people find it deeper in networking and less broad in hardware. Both cover a lot. Which is harder depends on your background.

Is Network+ harder than Security+?

They test different things. Network+ goes deeper on how networks work and how to fix them. Security+ goes deeper on security concepts and risk. Your own experience decides which feels harder.

How much of the exam is subnetting?

CompTIA does not publish topic-level question counts. Addressing sits in Networking Concepts (23%), and it also helps in troubleshooting scenarios, so be quick with it.
