What you'll learn
- Test your readiness for CompTIA Network+ N10-009 with 500 questions weighted like the five official exam domains
- Recognise ports, protocols, appliances, cloud concepts and modern technologies such as SD-WAN, VXLAN, zero trust and SASE
- Calculate subnets, summaries and IPv6 address forms, and interpret output from ping, tracert, dig, netstat, arp and show commands
- Apply the troubleshooting methodology to cabling, interface, service, wireless and performance problems in realistic scenarios
- Tell apart easily confused concepts such as RPO and RTO, IDS and IPS, DHCP relay and reservation, or a rogue AP and an evil twin
- Learn from feedback on every answer option and build up to a full-length, timed 100-question simulation

Description
Preparing for CompTIA Network+ and still finding N10-008 material? That exam retired in December 2024. The current exam is N10-009, and this course has been fully rebuilt for it: 500 new questions, written against the official CompTIA Network+ N10-009 exam objectives (version 4.0).
What changed since N10-008
The domains were renamed and reweighted
New topics: SD-WAN, VXLAN, Infrastructure as Code, zero trust architecture, SASE and SSE, DNSSEC and encrypted DNS
Much of the old hardware and 802.11 standards detail was dropped
Practice material written for N10-008 prepares you for an exam that no longer exists. Every question in this course follows the current N10-009 objectives.
Every practice test follows the official domain weighting
23% Networking Concepts
20% Network Implementation
19% Network Operations
14% Network Security
24% Network Troubleshooting
Five practice tests of 100 questions each, building up step by step
Test 1, Groundwork: one concept per question, short and direct
Test 2, In Practice: short scenarios that separate easily confused concepts
Test 3, Trade-offs: two reasonable answers, one constraint decides
Test 4, Under the Hood: subnetting, port numbers, command output and exact values
Test 5, Exam Day: long multi-constraint scenarios across all domains
Every answer option has its own explanation. For a wrong option, you learn what that option actually is, so the distinction sticks. Every question also has an overall explanation that ends with a link to the source documentation, such as RFCs, NIST publications or vendor documentation.
After each attempt, Udemy reports your score per domain, so you can see exactly where to focus. The pass mark is 80% for Tests 1 to 4 and 85% for Test 5, higher than the real exam requires, so a pass here leaves you some margin.
What this course is not: it is not a video course, and it does not contain real exam questions. The real N10-009 exam also includes performance-based questions, which a practice-test format cannot reproduce. Use these practice exams alongside the official objectives and a full study course.

Who this course is for:
- Candidates for CompTIA Network+ N10-009, the current exam that replaced N10-008 in December 2024
- Help desk and desktop support staff moving into networking, and junior network administrators and support technicians
- Students and career switchers building a first IT certification path after or alongside CompTIA A+
- N10-008 learners: N10-009 renamed and reweighted the domains, and older question banks still test removed topics
- Not for you if you want a video course: these practice tests test and explain, they do not replace hands-on practice
