✍️ Sample CWS Questions & Answers
1. Which growth factor plays a primary role in stimulating angiogenesis during wound healing?
VEGF is the principal mediator of angiogenesis, promoting new blood vessel formation essential for granulation tissue development.
2. Why does using many SSIDs on a single AP negatively impact network performance?
Each SSID generates its own beacon frames at the beacon interval, consuming shared airtime and reducing capacity for data traffic.
3. A -70 dBm received signal level at a wireless client is generally considered to be:
-70 dBm is generally considered a good received signal level, adequate for most WLAN applications though not as strong as -50 to -60 dBm.
4. What is the recommended minimum overlap between adjacent access point coverage cells in an enterprise WLAN for seamless roaming?
A 15-20% cell overlap ensures that roaming clients maintain a usable signal from the new AP before completely losing signal from the old one, enabling seamless handoff.
5. U-APSD (Unscheduled Automatic Power Save Delivery) is a QoS-aware power-save mechanism. How does a client trigger delivery of buffered frames from the AP?
In U-APSD, the client sends a trigger frame (a QoS Data or QoS Null frame) to the AP, which then delivers buffered downlink frames for that AC immediately.
6. A patient's pressure injury presents as intact skin with non-blanchable erythema. This is classified as which stage?
Stage 1 pressure injuries are characterized by intact skin with localized non-blanchable erythema, typically over a bony prominence.
