CompTIA Network+ (N10-009)

Network teams need a shared baseline before they can troubleshoot consistently, support mixed-vendor environments, or reduce escalation to senior admins. This beginner-level CompTIA Network+ (N10-008) course fits new IT Practitioners with about a year of networking exposure and experienced administrators who need to validate vendor-neutral fundamentals across addressing, routing, switching, wireless, security, cloud, and operations.

IT Directors should note that the N10-008 exam has been retired, and this course retires April 12, 2025. For current certification prep, assign the newer CompTIA Network+ (N10-009) course. Use this course when teams still need N10-008-aligned reference training, onboarding support, or a structured refresher. Most listed skills run 45–95 minutes, so Team Leads can schedule learning in weekly blocks rather than pulling staff out of operations for full-day sessions. CBT Nuggets Playlists can help sequence assignments, and Team Reporting helps Training Managers track progress across cohorts.

This training helps IT teams build the practical vocabulary and decision-making baseline needed for day-to-day network support across mixed environments.

• Faster onboarding for junior admins: New team members learn common network models, topologies, appliances, cables, connectors, services, protocols, and ports so tickets can be triaged with less hand-holding.
• More consistent IP planning and troubleshooting: Coverage of IPv4, IPv6, subnetting, NAT, PAT, DHCP, DNS, and NTP helps teams diagnose addressing and name-resolution issues that commonly disrupt users.
• Stronger LAN operations: VLANs, 802.1Q trunking, LACP, Ethernet switching, spanning tree, routing, and route selection support cleaner change planning and fewer avoidable outages.
• Better operational readiness: Wireless LANs, high availability, access methods, cloud fundamentals, security concepts, and network operations give teams a broader foundation for production support and risk reduction.

Knowledge

• Network models, reference models, topologies, and common network types.
• Core services, protocols, and ports used in enterprise networks.
• IPv4 and IPv6 addressing, subnetting concepts, NAT, and PAT.
• Routing concepts, route selection, first-hop redundancy, and Layer 3 options.
• Switching, VLANs, trunking, LACP, spanning tree, wireless, cloud, and high availability fundamentals.
• Foundational security and network operations concepts relevant to daily administration.

Ability

• Explain how network components, media, connectors, appliances, and infrastructure devices fit together.
• Interpret IP addressing plans and recognize subnetting, DHCP, DNS, NTP, NAT, and PAT behavior.
• Compare LAN design choices such as VLANs, trunks, aggregation, switching, and spanning tree.
• Discuss routing and redundancy options with enough context to support troubleshooting and escalation.
• Identify common wireless, cloud, access, availability, and security considerations during network support.
• Use the course as N10-008-aligned reference material while planning a move to current Network+ N10-009 certification prep.
