✍️ Sample CWS Questions & Answers
1. How should an CWS professional handle unexpected results that differ from predictions?
Unexpected results are learning opportunities. Professional practice requires analysis of contributing factors and adaptation based on those findings.
2. Which frequency band provides the longest range but lowest throughput in typical WLAN deployments?
The 2.4 GHz band propagates farther due to its lower frequency but offers lower throughput and more interference than 5 GHz.
3. What is a corrective action in Certified Wireless Specialist quality systems?
Corrective actions address root causes of quality issues to prevent recurrence, going beyond temporary fixes to create lasting improvement.
4. Which device assigns IP addresses in a wireless network?
A DHCP (Dynamic Host Configuration Protocol) server automatically assigns IP addresses and other network configuration parameters to devices connected to a network. This simplifies network management by eliminating the need to manually configure each device's IP address, ensuring efficient network operation.
5. What can reduce signal interference in Wi-Fi?
Wi-Fi networks operate on specific channels, and if multiple networks or other electronic devices in the vicinity use the same channel, signal interference can occur. Changing your Wi-Fi router to a less congested channel can significantly reduce this interference. This improves signal quality, increases data transfer speeds, and provides a more stable wireless connection.
6. What does the term 'throughput' measure in a wireless network?
Throughput is the real-world data transfer rate, which is always lower than the theoretical PHY rate due to overhead, retransmissions, and contention.
