Courseiva
This free N10-009 practice test mirrors the structure and difficulty of the real CompTIA Network+ N10-009 exam. Every question is written against the official 2026 exam blueprint published by CompTIA, ensuring you practise exactly what the exam tests — not last year's objectives.
The N10-009 blueprint is divided into 5weighted domains. Questions on this page are distributed proportionally across each domain, so the mix you see here reflects the same weighting you'll face on exam day. High-weight domains like Network Troubleshooting and Networking Concepts contribute the most questions, meaning focused practice on these areas gives you the highest return on study time.
N10-009 Exam Blueprint — 5 Domains
Networking Concepts
Network Implementation
Network Operations
Network Security
Network Troubleshooting
34 numbered sets, 5 domain question banks, and targeted sessions — every page is a unique set of questions.
Each chapter page covers one topic in depth — theory, key concepts, and focused practice questions. Use these to close knowledge gaps before returning to full practice tests.
Getting the most from practice questions requires more than just clicking through answers. Here is the study method used by candidates who pass N10-009 on their first attempt:
Answer before revealing
Read each N10-009 question fully, eliminate obviously wrong choices, then commit to an answer before clicking to reveal. This active recall process is what builds lasting knowledge.
Read every explanation
Even when you answer correctly, read the full explanation. Knowing WHY the right answer is correct — and why the distractors are wrong — is what separates a 750 score from a 900 score.
Track weak domains
Note which N10-009 domains you get wrong most often. Then do a targeted 20-30 question session focused only on that domain until your accuracy improves.
Simulate exam pacing
The real N10-009 gives you roughly 1 minutes per question. Use the 60 or 120-question sessions to practise hitting that pace comfortably.
Most candidates who pass N10-009 on their first attempt report doing between 400 and 800 practice questions over 4–8 weeks of preparation. With 472+ questions in the Courseiva bank, you have more than enough material to build that repetition without seeing the same question twice.
Answer each question to reveal the full explanation and correct answer. This starter set is drawn from all 5 exam domains in blueprint proportion. Use the session selector to start a longer focused practice run.

A network technician is configuring a small office network with two subnets: 10.0.1.0/24 and 10.0.2.0/24. Each subnet has its own switch, and both switches are connected to a router with interfaces 10.0.1.1 and 10.0.2.1. Hosts on subnet A can ping the router's interface in their subnet but cannot ping hosts on subnet B. Which of the following is the most likely cause?

A user reports that they cannot access the internet. The technician tests connectivity: pinging the default gateway succeeds, but pinging a public IP address like 8.8.8.8 fails. Firewall logs show outbound ICMP to 8.8.8.8 is permitted. What is the most likely cause?

Answer all 20 questions to see your domain score breakdown
A structured study plan dramatically increases your chances of passing N10-009 on the first attempt. The most effective approach combines reading the official CompTIA documentation or a study guide, watching video explanations for difficult concepts, and then reinforcing everything with daily practice questions.
We recommend the following weekly structure for N10-009 preparation:
Cover each N10-009 domain systematically. Read the exam objectives, watch explanatory content, and do 10–20 practice questions per domain to test understanding as you go.
Run full 50–60 question mixed sessions daily. Review every wrong answer in detail. Identify which domains are consistently scoring below 70% and revisit those study materials.
Do 100–120 question timed sessions to simulate real exam conditions. Aim for consistent scores above 80% before booking your exam date. A score above 80% in practice typically translates to a passing N10-009 score.
On exam day, the N10-009 tests your ability to apply knowledge to realistic scenarios — not just recall definitions. This is why reading explanations and understanding the reasoning behind every answer matters more than simply grinding question volume. Use the high-count sessions (100, 120) in the final weeks as your confidence benchmark.

Scaled scoring
The N10-009 exam uses a scaled scoring system — your raw score of correct answers is converted to a score out of 1000. A passing score of 720/1000 does not mean you need 72% of questions correct; the conversion accounts for question difficulty. Consistently scoring above 75–80% on practice tests puts you in a strong position to achieve 720/1000 on the real exam.
N10-009 includes performance-based questions (PBQs) alongside standard multiple-choice. PBQs ask you to complete simulated tasks in a lab environment. The domain knowledge you build here applies equally to both question types.
Multiple-choice and performance-based questions covering network infrastructure, IP addressing, switching, routing, security, operations, and troubleshooting.

Every question is written against the official N10-009 exam blueprint published by CompTIA. Our questions follow the same wording style, scenario complexity, and answer structure as the actual exam. They are original questions — not brain dumps — so you learn the underlying concepts and reasoning, not just memorised answers. Candidates who study with brain dumps often pass but have no transferable knowledge; Courseiva questions make you genuinely competent.
Most candidates who pass N10-009 on their first attempt do 30–60 questions per day. Use the Quick 10 session for daily warm-ups when you are short on time. On study days, run a 50 or 60-question session to build stamina. Reserve 100 and 120-question sessions for the final two weeks when you want to simulate real exam conditions and benchmark your readiness.
The N10-009 covers 5 domains: Networking Concepts (23%), Network Implementation (20%), Network Operations (19%), Network Security (14%), Network Troubleshooting (24%). Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — Network Troubleshooting and Networking Concepts — should receive the most attention.
Exam dumps are memorised question-and-answer lists taken from actual exam papers, often obtained illegally and shared without CompTIA's authorisation. Using them violates your NDA and CompTIA's certification agreement, and can result in certification revocation. Courseiva questions are original — AI-assisted, checked against the official exam objectives, and published under the editorial oversight of an engineer with 12+ years' experience. They test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
