CompTIA Network+ (N10-009) 5-Domain Structure
The 90 questions on the Network+ exam map proportionally to 5 core domains:
Networking Fundamentals
OSI and TCP/IP models, IPv4/IPv6 addressing and subnetting, common network ports and protocols, topologies, and copper/fiber cabling standards.
- OSI & TCP/IP Layer Model & Encapsulation
- IPv4 Addressing, Subnetting & CIDR Math
- IPv6 Addressing Schemes, SLAAC & EUI-64
Network Implementations
Routing protocols (OSPF, BGP, RIP), switching concepts (VLANs, 802.1Q, STP, PoE, LACP), wireless standards (802.11a-be), and cloud/virtualized networking architectures.
- Dynamic & Static Routing (OSPF, BGP, Admin Distance)
- VLANs, 802.1Q Trunking & Native VLAN Security
- Spanning Tree Protocol (STP 802.1D / RSTP 802.1w)
Network Operations
Monitoring solutions (SNMPv3, Syslog, NetFlow), network documentation, change management, business continuity, disaster recovery, and high availability (FHRP, load balancing).
- SNMPv3 Architecture, Syslog Levels & NetFlow
- Change Management & Standard Operating Procedures
- High Availability, FHRP (VRRP/HSRP) & Load Balancing
Network Security
Security concepts (CIA, Zero Trust), threat vectors and attacks (MitM, ARP poisoning, DoS), hardening (DHCP snooping, port security, DAI), firewalls, AAA (RADIUS/TACACS+), and IPsec/VPN cryptography.
- Threat Vectors: MitM, ARP/DNS Poisoning & DoS
- Switchport Hardening: Port Security, DHCP Snooping & DAI
- Firewalls, NGFW, IDS vs. IPS & Proxies
Network Troubleshooting
CompTIA 7-step troubleshooting methodology, hardware testing tools (OTDR, cable tester, tone probe), CLI diagnostics (ping, traceroute, netstat, dig, tcpdump), and real-world copper, fiber, wireless, and service issues.
- CompTIA Official 7-Step Troubleshooting Methodology
- Hardware Diagnostic Tools (OTDR, TDR, Tone & Probe)
- CLI Utilities: ping, tracert, dig, netstat, iperf & tcpdump

Frequently Asked Questions (CompTIA Network+ N10-009)
What is the format, duration, and passing score of the CompTIA Network+ (N10-009) exam?
The CompTIA Network+ (N10-009) examination consists of a maximum of 90 multiple-choice and performance-based questions (PBQs) administered over 90 minutes. The passing score is 720 on a scale of 100 to 900 (approximately 77.5% raw accuracy).
How is the N10-009 exam weighted across CompTIA's 5 blueprint domains?
The exam is proportioned strictly across 5 domains: Domain 1.0 Networking Fundamentals (24%, ~22 Qs); Domain 2.0 Network Implementations (19%, ~17 Qs); Domain 3.0 Network Operations (16%, ~14 Qs); Domain 4.0 Network Security (19%, ~17 Qs); and Domain 5.0 Network Troubleshooting (22%, ~20 Qs).
What major changes were introduced in N10-009 compared to the retired N10-008?
N10-009 expands emphasis on modern Wi-Fi 6E (6 GHz band) and Wi-Fi 7 (802.11be), spine-and-leaf datacenter architectures, software-defined networking (SDN), Zero Trust architecture (ZTA), and cloud networking (VPCs, transit gateways, direct cloud interconnects), while trimming legacy telephony and obsolete bus topologies.
What is the official CompTIA 7-step troubleshooting methodology tested on the exam?
The standardized sequence is: 1) Identify the problem; 2) Establish a theory of probable cause (question the obvious); 3) Test the theory to determine cause; 4) Establish a plan of action and identify potential effects; 5) Implement the solution or escalate; 6) Verify full system functionality and implement preventive measures; and 7) Document findings, actions, and outcomes.
What subnetting skills are required for CompTIA Network+?
Candidates must be able to calculate IPv4 subnets quickly without a calculator, including determining usable host ranges for /24 through /30 prefixes, calculating block sizes (increments), identifying broadcast addresses, and distinguishing RFC 1918 private scopes (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) and APIPA (169.254.0.0/16).
