About this exam
The CompTIA Network+ (N10-009) Examination is a vendor-neutral certification for people building foundational networking skills. It is commonly pursued by aspiring IT support specialists, network support technicians, and junior network administrators in the United States. The exam assesses whether candidates can understand, implement, operate, secure, and troubleshoot networks; it is not a license or a guarantee of employment. There are no formal prerequisites, but hands-on familiarity with computers and basic networking concepts can make preparation more manageable.
The N10-009 exam covers networking concepts, network implementation, network operations, network security, and network troubleshooting. Candidates should review the OSI model, TCP/IP and common protocols, IPv4 and IPv6 addressing, subnetting, routing, switching, VLANs, and wireless and security fundamentals. The exam uses multiple-choice questions and performance-based questions that ask you to apply knowledge to realistic tasks; it allows up to 90 questions in 90 minutes. Strong preparation combines concept review with scenario-based practice, especially for troubleshooting and configuration.
How to prepare for the CompTIA Network+ N10-009 exam
- Use CompTIA’s current N10-009 exam objectives as a checklist, and review each domain rather than relying on a general networking course outline.
- Practice IPv4 and IPv6 subnetting, interpreting routing tables, and diagnosing VLAN or connectivity problems; explain why each answer is correct, not just which answer to choose.
- Take timed, mixed-topic practice sessions that include performance-based scenarios, then use missed questions to identify weak areas and revisit the relevant concepts.
