✍️ Sample CWT Questions & Answers
1. How does a PoE Power Sourcing Equipment (PSE) detect a valid Powered Device (PD) before applying full power?
A PSE applies a low-voltage DC detection signal to identify the characteristic resistive signature (approximately 25kΩ) of a valid PD before committing full power.
2. In Certified Wireless Technician practice, what is the FIRST step when a safety hazard is identified in the workplace?
When a safety hazard is identified, the immediate priority is to secure the area to prevent injury and report the hazard through proper channels.
3. What is the PRIMARY purpose of obtaining CWT certification in Certified Wireless Technician?
Certification demonstrates verified competency and adherence to professional standards.
4. What is the 802.11v standard and what feature does it add for wireless network management?
802.11v (BSS Transition Management) enables APs to proactively suggest that clients roam to a better AP, helping the network steer clients away from congested or weak APs.
5. A technician notices that wireless clients in a conference room experience high latency during large meetings. Which likely cause should be investigated first?
High client density causes increased 802.11 medium contention, leading to longer backoff times and elevated latency as all clients compete for airtime on the same channel.
6. What best practice should be followed when planning power budgets for a PoE switch in a wireless deployment?
Summing per-device class power requirements and adding 20–25% headroom prevents power budget exhaustion, accommodating startup surges and future device additions.
