Lesson 1: How the N10-009 Exam Works

What this level does

Before you study any networking, you need to know what you are preparing for. This level sets out the exam's format, its scoring, its five domains and what this course does and does not offer.

Read this first: this course is independent of CompTIA. It is not written, authorized or endorsed by CompTIA, and it does not promise that you will pass.

Step 1: Learn the exam's format

CompTIA Network+ is a certification exam for people who build, run and fix networks. The exam code is N10-009. Commit these facts to memory:

Three points need explaining.

1. "Maximum of 90" is a ceiling. Your exam may contain fewer than 90 questions. The 90 minutes do not change.
2. 720 is a scaled score. The scale runs from 100 to 900, so 720 is not "720 out of 900 questions" and should not be read as a simple percentage of questions correct. Your aim is to reach 720 or higher.
3. There are two question types.
   • Multiple-choice: you read a question, often a short scenario, and select the best answer or answers.
   • Performance-based: you complete a task instead of picking from a list. For example, you might match items, place devices or complete a configuration in a simulated environment. These take longer than multiple-choice questions.

What to do: plan your time now. With up to 90 questions in 90 minutes, you have about one minute per question on average. Performance-based questions use more than that, so you must answer straightforward multiple-choice questions faster.

Step 2: Learn the five domains and their weights

CompTIA publishes a document called the exam objectives. It lists everything the exam can measure, grouped into five domains. Each domain has a percentage that shows how much of the exam it represents.

Read the table like a technician reading a work schedule:

• Network Troubleshooting (24%) is the largest domain. Diagnosing faults is the single most heavily measured skill.
• Networking Concepts (23%) is almost as large. Together these two domains make up 47% of the exam.
• Network Security (14%) is the smallest domain, but it is still about one-seventh of the exam. Do not skip it.

CompTIA also notes that the bulleted examples in the objectives are not exhaustive. Related technologies, processes or tasks may appear on the exam even if they are not listed.

Step 3: See how this course follows the domains

This course has 63 levels. They are organized as follows:

1. This level is orientation.
2. The remaining levels work through the domains in CompTIA's order, from 1.0 Networking Concepts to 5.0 Network Troubleshooting.
3. Each domain receives a share of levels roughly in proportion to its weight. Heavier domains get more levels.
4. Every level ends with the exam's angle on its topic.

What to do: when you feel short of study time, use the weights to decide where to spend it. An hour on a 24% domain usually returns more than an hour on a 14% domain.

Step 4: Understand what this course is and is not

Independent of CompTIA. CompTIA writes and owns the exam. This course is a separate study aid built around the published objectives.

Original practice questions only. Every check in this course is an original practice question written for teaching. None is a real exam question, and none should be described as one. This matters for your certification:

• CompTIA does not authorize or endorse content from unauthorized third-party training sites, which it calls "brain dumps".
• CompTIA states that individuals who use such materials to prepare will have their certifications revoked and be suspended from future testing, in accordance with the CompTIA Candidate Agreement.
• If you are unsure whether a study resource is unauthorized, CompTIA directs you to ask at examsecurity@comptia.org.

No pass is guaranteed. The course can explain the material and give you practice. It cannot control your preparation, the questions you receive or your result on the day.

What to do: avoid any site that claims to offer "real" or "actual" N10-009 questions. Review the CompTIA Certification Exam Policies before you begin studying.

Step 5: Check the recommended experience

The exam objectives state the recommended experience as a minimum of 9-12 months of experience in the IT networking field. CompTIA's certification page adds the CompTIA A+ certification to that recommendation.

This is a recommendation, not an entry requirement. It describes the background the exam is written for. You can book the exam without it.

What to do: if you have less hands-on experience, expect to spend more time on practical topics such as commands, cabling and troubleshooting scenarios. This course explains each term from first principles for that reason.

Step 6: Confirm the exam version before you book

CompTIA launched N10-009 on June 20, 2024, and its website lists an estimated retirement in 2027. Before you schedule, confirm on CompTIA's website that N10-009 is still the exam you intend to take.

What the exam asks about this

The exam does not test its own format, so you will not be asked for the passing score. This level matters for strategy:

• Expect scenario-based multiple-choice questions and performance-based tasks.
• Expect troubleshooting and concepts to dominate.
• Expect time pressure.

Key takeaways

• N10-009: maximum of 90 questions, 90 minutes, multiple-choice and performance-based.
• Pass at 720 on a scale of 100-900. It is a scaled score.
• Domains: Networking Concepts 23%, Network Implementation 20%, Network Operations 19%, Network Security 14%, Network Troubleshooting 24%.
• The course's levels follow the domains in order and in rough proportion to their weights.
• This course is independent of CompTIA, uses only original practice questions and promises no pass.
• 9-12 months of IT networking experience is recommended, not required.
