1. Which is a common wireless security risk? → Open network with no encryption
2. What can reduce signal interference in Wi-Fi? → Change Wi-Fi channel
3. What is a MAC address used for? → To identify devices on a network
4. How should an CWS professional handle unexpected results that differ from predictions? → Analyze factors, document findings, and adjust the approach based on what was learned
5. What is the relationship between antenna gain and beamwidth? → Higher gain produces a narrower beamwidth
6. What is the advantage of conducting a predictive site survey using software tools before a physical survey? → It provides an estimated RF model to guide AP placement, saving time and cost
7. What causes interference in wireless networks? → Microwaves
8. What is the primary competency framework for Certified Wireless Specialist professionals? → Structured competency standards defined by the certifying body
9. What role does documentation play in Certified Wireless Specialist client communications? → It creates clear records of discussions, decisions, and agreements
10. What does the acronym EIRP stand for in the context of wireless networking? → Effective Isotropic Radiated Power
11. What does SSID stand for? → Service Set Identifier
12. What is a heat map in the context of a wireless site survey? → A visual representation of signal strength across a floor plan
13. What is the typical range of a standard Wi-Fi router indoors? → 150 feet
14. What is the first step in risk assessment for Certified Wireless Specialist professionals? → Identifying potential hazards and vulnerabilities in the specific context
15. When conducting an outdoor wireless site survey, which environmental factor is most likely to cause signal multipath? → Reflections off buildings, vehicles, and the ground
16. What is the maximum conducted (transmitter output) power permitted by the FCC under Part 15 rules for 2.4 GHz WLAN devices? → 1 watt (30 dBm)
17. What does RSSI stand for in wireless site surveys? → Received Signal Strength Indicator
18. How is the half-power beamwidth (HPBW) of an antenna defined? → The angular width of the main lobe where gain is within 3 dB of its maximum value
19. How should CWS professionals apply research findings to practice? → Critically evaluate applicability, adapt to context, and monitor outcomes
20. How should an CWS professional respond to discovering a compliance violation? → Report promptly, investigate root cause, and implement corrective actions
21. Which action helps prevent unauthorized access? → Changing default password
22. What is the role of QoS (Quality of Service) in a wireless network? → To prioritize certain traffic types (e.g., VoIP, video) to reduce latency and jitter
23. Why is evidence-based practice important in Certified Wireless Specialist? → It integrates best available evidence with expertise for improved outcomes
24. How do CWS professionals effectively transfer training knowledge to workplace practice? → Through supervised practice, mentoring, and progressive independence with feedback
25. Which protocol is used to secure wireless networks? → WPA2
26. What type of device connects computers within the same network? → Switch
27. How do CWS professionals integrate compliance into daily practice? → By embedding compliance requirements into standard operating procedures
28. What role does mentorship play in Certified Wireless Specialist professional development? → It provides guided learning from experienced practitioners to develop practical skills
29. What distinguishes risk mitigation from risk avoidance in Certified Wireless Specialist practice? → Mitigation reduces impact or likelihood while avoidance eliminates the activity entirely
30. What is the effect of enabling band steering on a dual-band AP? → It encourages capable clients to connect on the 5 GHz band to reduce 2.4 GHz congestion
