CompTIA Network+ (N10-009) practice exam: 900 questions on the V9 objectives, 197 drag-and-drop boards. 40 free N10-009 practice exam questions.
900 practice questions for CompTIA Network+ (N10-009), written to the V9 objectives and spread across all five domains in their published weightings. Every question carries an explanation that teaches the distinction it turned on, and 40 are free.CompTIA Network+ N10-009 practice exam is the vendor-neutral networking certification, and it is the exam most people sit between A+ and Security+. It covers what a network is made of, how it is built and operated, how it is defended and how it is fixed when it stops working. This practice exam holds 900 questions written against Exam Objectives Version 4.0. The document CompTIA publishes the V9 paper that launched in June 2024, and the split between domains follows the weightings printed in it rather than an even division.
Network+ tests whether you understand what a mechanism does and when it is the right one, not whether you can type a vendor's syntax. That is why the exam names seven show commands and no configuration commands at all, and why almost every question here starts from a situation rather than from a definition. The wrong preparation is memorizing command reference. The right preparation is being able to say what a symptom rules out: a port that is up and silent is not a cabling fault, a mask that is too narrow splits reachability on a power of two, and a link that is idle may be the protection working rather than anything broken. The questions are built around those distinctions.
Every question carries an explanation, and none of them restates the winning option. That distinction matters more than it sounds. An explanation that says a duplex mismatch is correct because the duplex was mismatched has taught you nothing you can carry to a question you have not seen. Each explanation here names the mechanism the question turned on, then the boundary where a different answer would have been the right one - why a discard is not an error, why a mask fault splits a segment arithmetically while a duplicate address makes one host unstable, why prioritizing traffic solves a contention problem and never a capacity one. Each also cites the objective it was written against, so you can take a topic you keep failing straight back to CompTIA's own document.
197 of the 900 questions are drag-and-drop boards, and they are spread across all five domains rather than concentrated where they were easiest to write. They exist because a large part of this syllabus is classification - which layer, which port role, which tool answers which question, which symptom points at which fault - and a four-option question tests recognition where a board tests whether you can separate five things that sound alike. Each board carries at least one tile that belongs nowhere, so it cannot be completed by elimination. There is a smaller set of questions built on real command output - a routing table, an interface counter, a resolution table, a path report - where the task is reading the output rather than recalling the command.
Exam Coach AI sits alongside the paper while you work. Ask it what a term means, how two things differ, or when you would choose one over the other, and it answers in a sentence or two without leaving the question you are on. It will not tell you which option to pick, and it will not comment on the question in front of you - that part is yours, and it stays yours whether you are two minutes or two hours into a sitting. The most useful on the vocabulary this exam is dense with the difference between an access port and a trunk port, between RPO and RTO, between a tap and a mirrored port.
A+ Core 1 has already introduced cabling, connectors, wireless standards and small-office networking, and Network+ is where all four stop being inventory and start being decisions. Core 1 asks what a fiber connector is; Network+ asks why the link will not come up when light is present at both ends. If you have sat Core 1 recently, the media and hardware material here will feel familiar and the routing, spanning tree and troubleshooting domains will not - budget your time accordingly. Going the other way, Network+ is the usual step before Security+, and the security domain here is deliberately the network-shaped half of that syllabus.
A sitting draws 90 questions from the pool of 900 and marks them out of 100. The pass mark is 70%, which is our own threshold and not a vendor scale. The 90 are drawn in the published domain weightings, so a sitting looks like the real paper's shape - roughly a quarter troubleshooting, a quarter concepts, and the rest split across implementation, operations and security. Your result breaks down by domain, so a pass with a weak domain still tells you where to go back to, and a fail tells you which of the five is actually costing you the exam.
