The CWNE study guide has 9 sections and about 4,626 words.
01RF measurements, antennas and link-budget assumptions
A dB value expresses a logarithmic ratio, while dBm expresses power referenced to one milliwatt. Antenna gain stated in dBi uses an isotropic reference and is not itself an absolute transmitter output.
385 words, about 2 min02Requirements, capacity and accountable wireless design
A wireless design starts with users, devices, applications, location, peak concurrency and measurable acceptance criteria. Define coverage and capacity separately.
365 words, about 2 min03Predictive, passive, active and spectrum observations
A predictive design models a location using supplied plans, device characteristics and material assumptions. A passive WLAN survey listens to relevant existing radio transmissions without associating as a traffic-generating client in the stated method.
378 words, about 2 min04WLAN forwarding, roaming and application architecture
A wireless service includes the client, AP radio, local switching or tunnel path, authentication, IP services and destination application. Controller-based, distributed and cloud-managed architectures divide management/control and forwarding responsibilities differently.
356 words, about 2 min05WLAN authentication, keying and protected access
A WLAN security design chooses supported identity, key-establishment and data-protection mechanisms for its users and devices. WPA-family labels are not interchangeable settings.
383 words, about 2 min06Wireless frame analysis and structured troubleshooting
A client can fail discovery, association, authentication, keying, address assignment, name resolution or application access. Correlate the actual client, AP, location and trustworthy timestamps.
369 words, about 2 min07Identity, access and cryptographic protection
This domain tests the identity lifecycle and the mechanisms that turn an identity into an authorised action. Expect questions that separate authentication from authorisation and that ask which access control model fits a scenario.
857 words, about 4 min08Security operations, monitoring and response
This domain is about running security as a repeatable service rather than a series of heroic acts. Questions target process ownership, change control and the operational metrics that show the programme is working.
803 words, about 4 min09Continuity, backup and technical recovery
This domain tests continuity planning: how an organisation keeps critical services running during disruption and how it recovers afterwards. Distinguish the continuity plan from the disaster recovery plan and know the time-based metrics precisely.
