What do 802.11 stations perform to help avoid collisions on the WLAN medium?
- A. Listen to verify that the medium is free before transmitting.
- B. Stations only transmit when polled by the access point.
- C. Transmit on a fixed schedule.
- D. 802.11 stations detect collisions and set a back-off timer.
Answer: A
Explanation:
Reference:
According to the IEEE 802.11 - Wikipedia document, one thing that 802.11 stations perform to help avoid collisions on the WLAN medium is to listen to verify that the medium is free before transmitting. This is part of the carrier-sense multiple access with collision avoidance (CSMA/CA) mechanism that 802.11 stations use to coordinate access to the shared medium.

- D. a honeypot AP
Answer: B
NEW QUESTION # 43
You have deployed location services at a site and have installed an application which includes the Mist SDK on Bluetooth-only mobile client devices. The devices with the SDK-enabled app have Bluetooth enabled, but the devices do not appear in the Mist GUI under Clients/App Clients.
What is causing this problem?
- A. There is BLE and Wi-Fi co-channel interference.
- B. The clients are connected to the wrong WLAN.
- C. The AP BLE radios do not hear the SDK-enabled client's BLE beacons.
- D. The client devices are not connected to Wi-Fi or to a cellular data plan.
Answer: C
Explanation:
Explanation
If Bluetooth-only mobile client devices with an SDK-enabled app do not appear in the Mist GUI under Clients/App Clients even though they have Bluetooth enabled, it could be because the AP BLE radios do not hear the SDK-enabled client's BLE beacons.
According to the Mist documentation1, Mist SDK is a software development kit that enables indoor location and proximity services using Mist's virtual Bluetooth LE (vBLE) technology. The SDK allows mobile applications to communicate with Mist APs using BLE beacons that are transmitted by the client devices.
The devices with the SDK-enabled app have Bluetooth enabled, but they do not appear in the Mist GUI under Clients/App Clients because the AP BLE radios do not hear the SDK-enabled client's BLE beacons. This could be due to various factors such as interference, distance, obstacles, or configuration issues that affect the BLE signal strength and quality.

What are basic data rates?
- A. optional data rates
- B. disabled data rates
- C. fastest data rates
- D. required data rates
Answer: D
Explanation:
Basic data rates are the required data rates that all devices on a wireless network must support in order to connect to the network. These rates are used for management and control frames and can affect the performance of the network.
According to the Lecture 3 - Radio Frequency and Antenna Fundamentals - Part 2 document2, basic data rates are required data rates that all devices must support to communicate on a WLAN.
NEW QUESTION # 50
Which two statements are correct about the radio frequency rule of 10s and 3s? (Choose two.)
- A. If the signal strength increases by 3 dB, the power is tripled.
- B. If the signal strength decreases by 10 dB, the power decreases tenfold.
- C. If the signal strength increases by 3 dB, the power is doubled.
- D. If the signal strength decreases by 10 dB, the power is halved.
Answer: B,C
Explanation:
Explanation
According to the radio frequency rule of 10s and 3s, for every loss or gain of 10 dBm, you divide or multiply the power in mW by 10. For every loss or gain of 3 dBm, you divide or multiply the power in mW by 2 1.
