1. Which of the following BEST defines the organizational goal of 'coverage' in a WLAN design? → Providing a minimum signal strength level throughout all required physical areas.
2. What is the fundamental channel access method that is a mandatory part of the 802.11 standard, based on the principle of "listen before you talk"? → Distributed Coordination Function (DCF)
3. During the process of connecting to a Wi-Fi network, what is the first type of active frame a client device typically sends to discover available access points? → Probe Request
4. Which of the following are pressure ulcer risk factors? → All of the above
5. What does the term 'sticky client' refer to in a WLAN environment? → A client that refuses to roam away from a weak AP signal
6. A technician is deploying a new Wi-Fi 6 access point that requires 22 watts of power. Which IEEE PoE standard is the minimum requirement to power this device? → 802.3at (PoE+)
7. During the initial planning phase for a new WLAN, what is the primary purpose of defining the types of devices and applications that will use the network? → To establish the capacity and performance requirements.
8. What problem does load balancing address in a multi-AP WLAN deployment? → Prevents too many clients from associating with one AP while nearby APs are underutilized
9. What is the primary purpose of a transparent film dressing? → Maintain a moist wound environment while allowing gas exchange on low-exudate wounds
10. What is the primary function of the 802.11e amendment? → To introduce Quality of Service (QoS) enhancements.
11. Which of the following is a key feature of the 802.11ac standard that distinguishes it from 802.11n? → Exclusive operation in the 5 GHz band
12. What does SNR (Signal-to-Noise Ratio) measure in a wireless network? → The difference in dB between received signal strength and the noise floor
13. Which TXOP parameter in WMM defines the maximum time a station may transmit after winning channel access? → TXOP Limit
14. The amount of protein needed in the diet to encourage wound healing is: → 1.25 to 1.5 g/kg per day
15. Which of the following uniquely identifies a Basic Service Set (BSS) and is typically the MAC address of the access point's radio? → Basic Service Set Identifier (BSSID)
16. Which QoS mechanism in 802.11 replaces the legacy DCF for differentiated traffic handling? → EDCA (Enhanced Distributed Channel Access)
17. Which sort of insert relieves pressure when contemplating orthotics and shoe inserts for patients with a neuropathic foot? → Semi-rigid
18. What is the purpose of conducting a post-deployment site survey for WLAN troubleshooting? → To verify that actual signal coverage and channel usage match the design
19. Which tool uses a color-coded visual guide to classify wound tissue types (black, yellow, red, pink)? → RYB (Red-Yellow-Black) wound color classification
20. What is the primary goal of negative pressure wound therapy (NPWT)? → Remove excess exudate, reduce edema, and promote granulation tissue formation
21. Which type of barrier protection is the best for intact skin to keep it safe from exudate and adhesive stripping? → Skin sealant
22. What is the function of 802.11v BSS Transition Management? → Allows APs to suggest roaming targets to clients
23. Which of the following therapies is recommended as a first line of treatment for weepy, red, itchy atopic dermatitis? → Wet aluminum acetate compresses
24. What is the best dressing to use when a deep ulcerated area has a lot of exudate and the drainage is caused by tumor necrosis? → Alginate
25. Subcutaneous tissue may be damaged or necrosed during full-thickness skin loss. → Stage III
26. Which of the following units of measurement represents an absolute power level referenced to 1 milliwatt? → dBm
27. What is the purpose of 802.11k in a wireless network? → Radio Resource Management for neighbor reports
