During a post-implementation survey, you have detected a non-802.11 wireless device transmitting in the area used by handheld 802.11g scanners. What is the most important factor in determining the impact of this non-802.11 device?
- A. Airtime utilization
- B. Channel occupied
- C. Protocols utilized
- D. Receive sensitivity
Answer: A
Explanation:
Airtime Utilization is a per-channel statistic that defines what percentage of the channel is currently being used, and what percentage is therefore free. Airtime usage can come from: Data traffic to and from client devices. Interference from WiFi and non-WiFi sources. Management overhead from APs and client devices. https://wyebot.com/2019/06/06/understanding-airtime-utilization/
NEW QUESTION 78

- C. WEP
- D. SSID hiding
Answer: A
NEW QUESTION 79
A client complains of low data rates on his computer. When you evaluate the situation, you see that the signal strength is -84 dBm and the noise floor is -96 dBm. The client is an 802.11ac client and connects to an 802.11ac AP. Both the client and AP are 2x2:2 devices. What is the likely cause of the low data rate issue?
- A. Lack of support for 802.11n
- B. Too few spatial streams
- C. CAT5e cabling run to the AP
- D. Weak signal strength
Answer: D
NEW QUESTION 80

NEW QUESTION 82
You are attempting to locate the cause of a performance problem in two WLAN cells in a mostly overlapping coverage area. You note that one AP is on channel 1 and the other is on channel 2.
When you document yoy findings, what term do you use to describe the problem in this configuration?
- A. CCI
- B. Bluetooth interference
