🌐 CompTIA Network+ N10-009 (Exam-Prep)
Free exam-prep for CompTIA Network+ (N10-009) with a signed certificate. Learn the modules, pass the 10-question exam, EN/FR/AR, no account.
Last updated: June 2026
An independent, free exam-preparation course built around the publicly published CompTIA Network+ N10-009 exam objectives — networking concepts, infrastructure and implementation, network operations, security, and troubleshooting — with visual lessons, original self-check questions and a final exam. It is awareness and preparation only; it is not the official CompTIA course or exam and is not affiliated with or endorsed by CompTIA. The course is organized into 12 modules, ending with a final exam (pass mark 70%). It is independent, free exam-preparation training — not an official or accredited review course.

Learning objectives
- Understand that this is independent N10-009 exam-prep over the public exam objectives, not the official CompTIA course or exam
- Name the five exam domains and their weightings: Networking Concepts (23%), Network Implementation (20%), Network Operations (19%), Network Security (14%), Network Troubleshooting (24%)
- Explain the OSI model, encapsulation, common ports/protocols, and IPv4/IPv6 addressing including subnetting and CIDR
- Identify cabling, connectors, transceivers, network devices, and physical/logical topologies
- Compare network architecture tiers, SDN, virtualization, and cloud connectivity (IaaS/SaaS, VPC, gateways)
- Configure and secure wireless (802.11 standards, channels, security) and routing/switching technologies (VLANs, STP, NAT, routing protocols)
- Apply network operations: documentation, SNMP/syslog monitoring, high availability, disaster recovery, and change management
- Apply security: the CIA triad, defense in depth, common attacks, hardening, NAC, and Zero Trust
- Use a structured troubleshooting methodology with the right tools (ping, traceroute, ipconfig/ip, nmap, cable testers) to resolve faults
- Sit a 10-question exam-style final (80% to pass) built from original questions spanning all five domains
