One of the most thorough assessments of networking abilities among the available credentials is the CNAE-101 (Certified Network Administrator & Engineer) exam. By bridging theory and practice, it guarantees that candidates can configure and troubleshoot real-world systems in addition to understanding the concepts. This post provides a thorough explanation of CNAE-101, including its definition, topics covered, preparation tips, and potential career effects.
What is CNAE-101?
The dual duties of network administrators and engineers are the focus of the mid-level certification CNAE-101. CNAE-101 strikes a balance between fundamental concepts and applied engineering, in contrast to entry-level certificates that mostly emphasise conceptual knowledge. Candidates must be familiar with both design-level duties, such as creating IP addressing schemes, putting security policies into place, and maximising performance, as well as daily administration duties, such as managing users, configuring devices, or keeping an eye on the health of the network.
The certification is well-suited for IT professionals who:
- Work with wired and wireless infrastructures
- Support enterprise connectivity and troubleshooting
- Are looking to advance into mid-level or senior technical roles
- Want to build a foundation before pursuing higher vendor-specific or advanced certifications
Domains and Knowledge Areas
Here’s a closer look at the CNAE-101 exam domains, broken into detail:
- Network Fundamentals
Candidates must be comfortable with:
- OSI model layers and their functions
- TCP/IP protocols (IPv4 and IPv6)
- Ethernet standards, cabling types, and physical connections
- Core devices: switches, routers, bridges, hubs
This domain ensures you can explain the “why” behind networking decisions.
- Routing and Switching
Skills expected here include:
- VLAN configuration and management
- Trunking and inter-VLAN routing
- Static routes and the introduction of dynamic routing protocols
- Troubleshooting loops, routing errors, and spanning tree issues
This section forms the backbone of enterprise networking knowledge.
- Security Principles
Security is woven into every modern network. You must know:
- Access Control Lists (ACLs) and traffic filtering
- Switch-level security (port security, MAC filtering)
- Secure remote management with SSH
- Concepts of AAA (Authentication, Authorization, Accounting)
- Wireless Networking
While the exam leans heavily on wired technologies, wireless is included because of its dominance in modern work environments. Focus areas include:
- Wi-Fi standards (802.11a/b/g/n/ac/ax)
- Frequency bands, channels, and interference sources
- WPA2/WPA3 security protocols
- Wireless coverage, roaming, and site planning basics
- Performance and Monitoring
This domain tests your ability to ensure networks run smoothly:
- Understanding latency, jitter, packet loss, and throughput
- Implementing Quality of Service (QoS) for traffic prioritization
- Monitoring via SNMP and syslog
- Using tools for diagnostics and long-term performance tracking
- Troubleshooting and Diagnostics
One of the most critical skills:
- Structured troubleshooting methodology
- Commands and tools like ping, traceroute, nslookup, netstat
- Isolating IP addressing and subnetting issues
- Resolving VLAN, DHCP, and DNS misconfigurations
Preparation Strategies
A strong preparation plan can make all the difference.
Build a Study Roadmap
Start with the official exam objectives and create a checklist. Divide your study time across the domains, ensuring no topic is overlooked.
Hands-On Practice
Theory is not enough for CNAE-101. Build a virtual lab using tools like Cisco Packet Tracer, GNS3, or EVE-NG. Configure VLANs, apply ACLs, simulate wireless setups, and troubleshoot intentionally broken networks.
Focus on Subnetting
Subnetting remains one of the biggest stumbling blocks. Practice until you can calculate subnets quickly without relying on calculators.
Emphasize Security and Wireless
Avoid the error of neglecting these areas. Wireless knowledge is becoming more and more necessary, even if your daily work is wired.
Practice Exams
To become accustomed to timing and scenario formats, take practice exams. These boost confidence and draw attention to areas of weakness.

Career Opportunities
With CNAE-101, you can pursue roles such as:
- Junior/Mid-Level Network Administrator
- Network Engineer
- Wireless Technician
- IT Infrastructure Engineer
- Systems Support Specialist
Beyond job titles, CNAE-101 provides you with the practical credibility to manage routine network tasks, such as securing remote connections and onboarding new devices.
Many professionals also use this certification to launch into advanced learning:
- Cisco CCNA/CCNP for vendor-specific expertise
- CWNP certifications for wireless specialization
- CompTIA Security+ or CySA+ for network security paths
- Cloud certifications (AWS, Azure, GCP) as networking converges with cloud services
Four-Week Study Plan
- Week 1: Review fundamentals, subnetting, OSI/TCP-IP.
- Week 2: VLANs, routing, and switch troubleshooting labs.
- Week 3: Wireless, ACLs, and network security configurations.
- Week 4: Practice exams, timed mock tests, final review of weak areas.
Adapt this timetable to your experience and free time. Newcomers might benefit from a slower pace, while candidates with practical experience might require less review.
If you are serious about elevating your networking career, CNAE-101 is a smart choice. By following a structured study plan, practicing hands-on labs, and taking practice tests, you’ll be well-prepared to earn the certification and apply your skills in the real world.
