(4) Network Security (19%)

The 2026 version focuses on strengthening modules that meet the security needs of enterprises

Threat protection: common attack and defense methods such as DDoS, ARP spoofing, port scanning, etc.

Access control: ACL, 802.1X, AAA authentication, minimum privilege principle

Security technologies: VPN, firewall, IDS/IPS, WPA3 wireless encryption

New Security: Zero Trust Security Architecture, Software Defined Boundaries (SDP) Basic Concepts

Equipment reinforcement: disabling insecure services, password policies, SSH replacing Telnet

Security Compliance: Enterprise Network Security Standards, Data Transmission Encryption Requirements

(5) Network Troubleshooting (22%)

The core module with the highest proportion tests practical problem-solving ability:

Troubleshooting process: Standardized fault location, analysis, resolution, and verification closed-loop

Connectivity troubleshooting: using ping, tracert, pathping tools and fault analysis

Equipment troubleshooting: interface failure, routing failure, VLAN configuration error, wireless connection failure

Service troubleshooting: DHCP address allocation failure, DNS resolution exception, NAT translation failure

Security troubleshooting: Access denied, traffic intercepted, wireless intrusion investigation

Cloud and SD-WAN troubleshooting: Cloud connection interruption, SD-WAN link fault location

3. Core Changes in the 2026 Exam

(1) Deep integration of cutting-edge technologies

New examination points have been added for AI network operation and maintenance, zero trust, Wi Fi 6, SD-WAN, 5G and IoT networks, and outdated technology content has been eliminated.

(2) Practical oriented comprehensive upgrade

The proportion of practical simulation questions (PBQ) has increased, requiring completion of real-world tasks such as equipment configuration and fault repair, and rejecting empty talk on paper.

(3) Strengthening the neutral advantage of manufacturers

Not bound to specific brand devices, focusing on universal standards and protocols, adapting to a mixed network environment of multiple vendors, with a wider employment coverage.

(4) Significant increase in safety weight

Take zero trust, boundary protection, and equipment reinforcement as the core examination points to match the essential needs of enterprise network security.

(5) Normalization of Cloud and Automation

Cloud network SDN and basic automation is included in the mandatory exam content, in line with the trend of digital transformation.

4. Exam skills and precautions

Single choice question shall be answered quickly, and each question shall not exceed 1 minute; reserve sufficient time for practical exercises and prioritize completing the questions that you will be able to do.

Carefully review the multiple-choice questions to ensure that all correct options are selected; Drag and drop questions arranged in logical order; Complete the configuration of practical exercises and verify the results.

Mark and skip difficult problems first to avoid excessive time consumption; after answering all the questions, go back and process the marked questions without leaving any blank spaces.

Familiarize yourself with the rules and interface of the examination room in advance; Bring valid identification and arrive at the examination room in advance; Maintain a stable mindset and focus on answering questions.

5. Certification Value and Career Development

CompTIA Network+ is a globally recognized gold certification for entry-level networking, unrestricted by vendors, and suitable for various enterprise networking positions. Holding this certification is suitable for positions such as network engineer, technical support engineer, cloud network operation and maintenance, and is also an ideal foundation for advanced certifications.

Summary: The new version of the CompTIA Network+ N10-009 exam in 2026 has completed the upgrade from traditional network certification to modern full stack network capability certification, covering both basic network knowledge and keeping up with trends in AI, cloud, security, and automation.
