An 802.11-based network uses an AP and has several connecting clients. The clients include iPhones, iPads, laptops and one desktop. What WLAN use case is represented?
正解：C
解説：
A BSS (Basic Service Set) is a WLAN use case that represents an 802.11-based network that uses an AP (Access Point) and has several connecting clients. The AP acts as a central point of coordination and communication for the clients, which can include iPhones, iPads, laptops, desktops, or any other devices that have Wi-Fi capabilities. A BSS can be identified by a unique BSSID (Basic Service Set Identifier), which is usually the MAC address of the AP's radio interface. A BSS can also be associated with an SSID (Service Set Identifier), which is a human-readable name that identifies the network. References: , Chapter 1, page 23; , Section 1.1

What is the final step in an effective troubleshooting process?
正解：D
解説：
The final step in an effective troubleshooting process is to document the results. Documentation is essential for keeping track of the problem history, the actions taken, the solutions implemented, and the outcomes achieved.
Documentation can also help to prevent future problems, improve best practices, and provide feedback for improvement. Documentation should include relevant information such as problem description, symptoms, root cause analysis, resolution steps, verification methods, and lessons learned.

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?
正解：A
解説：
Weak signal strength is the likely cause of the low data rate issue for the client that has a signal strength of -84 dBm and a noise floor of -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. Signal strength is the measure of how strong the RF signal is at the receiver. Signal strength can affect the reliability and performance of the wireless connection, as well as the data rate and throughput of the traffic. The higher the signal strength, the better the signal quality and the higher the data rate. The lower the signal strength, the worse the signal quality and the lower the data rate.
The data rate of an 802.11ac connection depends on several factors, such as channel bandwidth, modulation and coding scheme (MCS), spatial streams, guard interval, and beamforming.
However, these factors are also influenced by the signal strength, as they require a certain signal- to-noise ratio (SNR) to operate properly. SNR is the ratio of the signal strength to the noise floor, which is the measure of the background noise or interference in the RF environment. The higher the SNR, the more robust and efficient the communication. The lower the SNR, the more prone and vulnerable to errors and retries.
An 802.11ac connection with a channel bandwidth of 80 MHz, an MCS of 9, two spatial streams, a short guard interval, and no beamforming can achieve a maximum data rate of 867 Mbps.
However, this data rate requires a minimum SNR of 30 dB to maintain a sufficient signal quality. If the signal strength is -84 dBm and the noise floor is -96 dBm, then the SNR is only 12 dB (-84 dBm - (-96 dBm) = 12 dB), which is far below the required SNR for this data rate. Therefore, the data rate will drop significantly to match the lower SNR and signal quality.
To solve this problem, the signal strength should be increased to improve the SNR and data rate.
This can be done by adjusting the output power or channel assignment of the AP or client, relocating or reorienting some APs or antennas to reduce attenuation or interference, updating or replacing some faulty or outdated hardware or software components, etc.
質問 # 58
What channel width is defined as the default, and only mandatory, channel width for all 802.11 amendments prior to 802.11n?
正解：D
解説：
20 MHz has been the standard, mandatory channel width used by 802.11a, 802.11b (with an actual occupied bandwidth closer to 22 MHz), and 802.11g. Channel bonding to widths of 40 MHz, 80 MHz, and 160 MHz was introduced with later amendments, starting with 802.11n for 40 MHz channels, to increase available throughput. However, wider channels reduce the total number of non-overlapping channels available for reuse, which is an important tradeoff to consider during WLAN design, especially in the 2.4 GHz band and in high-density 5 GHz deployments.
質問 # 59
Which regulatory domain organization is responsible for defining RF power and channel regulations for WLAN devices operating in the United States?
正解：A
解説：
The Federal Communications Commission (FCC) is the regulatory body responsible for governing the use of RF spectrum in the United States, including the unlicensed ISM and U-NII bands used by WLAN devices. The FCC establishes rules regarding maximum transmit power, permissible channels, and technical requirements that WLAN equipment manufacturers must follow. Other countries and regions have their own regulatory bodies, such as ETSI in Europe, which may impose different power and channel restrictions.
