Detailed CWNA Exam Topics:
The CWNA exam assesses your foundational knowledge and skills in wireless networks across various key areas. While the specific questions and weightings may vary slightly, here's a breakdown of the major topics covered:
1. Radio Frequency (RF) Theory and Technologies:
- Electromagnetic spectrum and radio wave basics
- Frequency bands used in WLAN (2.4 GHz, 5 GHz, etc.)
- Signal propagation, attenuation, and interference
- Antenna types and characteristics (omni-directional, directional)
- RF safety and regulations
2. Wireless LAN Standards (802.11x):
- Key features and differences between various 802.11 standards (a, b, g, n, ac, ax)
- Physical layer (PHY) and Medium Access Control (MAC) layer operation
- Data rates, channel width, modulation techniques
- MIMO (Multiple-Input Multiple-Output) technology
3. WLAN Components:
- Access Points (APs): functions, types, modes (standalone, managed)
- Wireless clients (laptops, smartphones, IoT devices)
- Wireless LAN Controllers (WLCs): centralized management
- Repeaters, extenders, and mesh networks
4. WLAN Security:
- WEP (Wired Equivalent Privacy) and its vulnerabilities
- WPA (Wi-Fi Protected Access) versions and improvements (WPA2, WPA3)
- Authentication methods (PSK, 802.1X)
- Encryption protocols (TKIP, AES)
- Security best practices and hardening techniques
5. Site Surveys and Wireless Planning:
- Importance of conducting site surveys for optimal network deployment
- Tools and techniques for measuring signal strength, coverage, and interference
- Factors to consider in access point placement and channel selection
- Capacity planning and estimating user load
6. Basic WLAN Troubleshooting:
- Identifying common connectivity issues (signal strength, authentication errors)
- Tools for troubleshooting (ping, traceroute, packet capture)
- Basic troubleshooting methodologies (isolation, escalation)
- Understanding logs and monitoring wireless network performance
Additional Topics:
- Introduction to network fundamentals (TCP/IP, OSI model)
- Basic wireless LAN management tasks (creating SSIDs, setting security)
- Regulatory compliance and wireless spectrum considerations
- Emerging technologies in WLAN (Wi-Fi 6E, Mesh networking)
