4. Core Knowledge Modules for 2026

(1) Network Fundamentals (24%)

Focus on mastering the correspondence between the OSI seven-layer model and the TCP/IP four-layer model, and understanding the functions and protocols of each layer. Be proficient in IPv4/IPv6 addressing, subnetting, routing protocols, and switching technologies.

Remember key concepts: IP address classification, subnet mask calculation, default gateway, DNS, DHCP. This part is the foundation of all network knowledge; be sure to master it thoroughly to avoid losing points on basic questions.

(2) Network Implementation (19%)

Master the deployment and configuration of wired and wireless network devices. Understand the advantages and disadvantages of different network topologies, and be familiar with common cable standards and fiber optic types. Pay special attention to SDN and cloud network fundamentals, which are new additions to the 2026 exam.

Remember key technologies: VLAN configuration, port security, link aggregation, wireless encryption, 802.11ax standard. Emphasize practical operation; be able to select appropriate devices and topologies according to the scenario to achieve efficient network connections.

(3) Network Operations (16%)

Understand the use of network monitoring tools and master the analysis methods of network performance indicators. Be familiar with high availability technologies and disaster recovery strategies. Understand the importance of network document management, including topology diagrams, configuration files, IP address planning tables, etc. Focus on learning change management processes to ensure the security and controllability of network changes, which is the core standard of enterprise network operations.

(4) Network Security (19%)

The 2026 exam will focus on the zero-trust security concept, understanding the core principle of "never trust, always verify." Master common network attack types and defense methods. Be familiar with network security equipment and technologies.

Remember key products and standards: WPA3 wireless security, IPsec VPN, SSL/TLS, NAC. Be able to combine security technologies with business needs.

(5) Network Troubleshooting (22%)

This is the core module of the Network+ exam and the most commonly used skill in actual work. Master the structured troubleshooting methodology: identify the problem → collect information → formulate hypotheses → verify hypotheses → implement solutions → verify results → record the process. Be familiar with diagnosing and resolving common network problems: connectivity issues, performance issues, security issues, and wireless issues.

Focus on practicing performance-based mock exams, which account for approximately 20% of the exam and directly assess practical skills; these are key to passing the exam.
