• Transceivers and connectors: SC, LC, ST, MPO, RJ11, RJ45, F-type, BNC.
• Network topologies: mesh, hybrid, star/hub and spoke, spine and leaf, point-to-point, three-tier, and collapsed core.
• IPv4 addressing: public vs. private, APIPA, RFC1918, loopback, subnetting (VLSM, CIDR), and address classes (A, B, C, D, E).

Domain 2 - Network implementation (20%)

• Routing technologies: static and dynamic routing (BGP, EIGRP, OSPF), route selection, NAT, PAT, FHRP, VIP, and subinterfaces.
• Switching technologies: VLANs, interface configuration, spanning tree, MTU, and jumbo frames.
• Wireless devices: channels, frequency options, SSID, network types, encryption, guest networks, authentication, antennas, and access points.
• Physical installations: installation implications, power considerations, and environmental factors.

Domain 3 - Network operations (19%)

• Documentation: physical vs. logical diagrams, rack diagrams, cable maps, network diagrams, asset inventory, IPAM, SLA, and wireless surveys.
• Life-cycle management: EOL, EOS, software management, and decommissioning.
• Change management: request process tracking.
• Configuration management: production, backup, baseline configurations.
• Network monitoring: SNMP, flow data, packet capture, baseline metrics, log aggregation, API integration, and port mirroring.
• Disaster recovery: RPO, RTO, MTTR, MTBF, cold/warm/hot sites, active-active/passive, and testing.
• Network services: DHCP, SLAAC, DNS, NTP, PTP, and NTS.
• Access and management: VPNs, SSH, GUI, API, and console.

Domain 4 - Network security (14%)

• Audits and compliance: data locality, PCI DSS, and GDPR.
• Network segmentation: IoT, IIoT, SCADA, ICS, OT, guest, and BYOD.
• Types of attacks: DoS/DDoS, VLAN hopping, MAC flooding, ARP poisoning/spoofing, DNS poisoning/spoofing, rogue devices/services, evil twin, on-path attack, and social engineering (phishing, dumpster diving, shoulder surfing, tailgating).
• Security features and defense: device hardening, NAC, key management, ACL, URL/content filtering, trusted vs. untrusted zones, and screened subnet.

Domain 5 - Network troubleshooting (24%)

• Troubleshooting methodology: identifying the problem, establishing a theory, testing, planning, and implementing a solution, verifying functionality, and documenting findings.
• Cabling and physical interface issues: cable issues (incorrect type, signal degradation, improper termination, TX/RX transposed), interface issues (increasing counters, port status), and hardware issues (PoE, transceiver mismatch, signal strength).
• Network services issues: switching issues (STP, VLAN assignment, ACLs), routing issues (routing table and default routes), address pool exhaustion, and incorrect gateway/IP/subnet mask.
