질문 # 100
You are troubleshooting a client issue on a Windows laptop. The laptop can see and connect to
2.4 GHz APs, but is does not even see 5 GHz APs. While evaluating the issue, you determine that this problem is happening for all of the laptops of this model in the organization. Several other tablets connect on channel 48 and channel 52 in the same work areas. What is the likely problem?
정답：A
설명：
The client drivers are faulty and should be upgraded is the likely problem for the laptop that can see and connect to 2.4 GHz APs, but does not even see 5 GHz APs. The client drivers are the software components that enable the wireless adapter of the laptop to communicate with the operating system and the network. The client drivers are responsible for scanning the available wireless channels, detecting and connecting to the access points, negotiating the security and data rate parameters, and transmitting and receiving data frames. If the client drivers are faulty, outdated, or incompatible, they may cause various issues with the wireless performance and functionality, such as low data rates, poor signal strength, frequent disconnections, or inability to see or connect to certain access points or channels.
One of the possible causes of faulty client drivers is that they do not support or recognize some of the features or standards of the 802.11ac technology, such as wider channel bandwidths, higher modulation schemes, or DFS (Dynamic Frequency Selection) channels. This could explain why the laptop can see and connect to 2.4 GHz APs, but not 5 GHz APs, as 802.11ac operates only in the 5 GHz band and uses channels that are wider (up to 160 MHz) and higher (up to channel
165) than those used by previous standards. Moreover, some of the 5 GHz channels are subject to DFS rules, which require the access points and client stations to monitor and avoid using channels that are occupied by radar systems or other primary users. If the client drivers do not support or comply with DFS rules, they may not be able to see or connect to access points that use DFS channels. To solve this problem, the client drivers should be upgraded to the latest version that supports and is compatible with 802.11ac features and standards. This can be done by downloading and installing the updated driver software from the manufacturer's website or using a device manager tool. Upgrading the client drivers may also improve other aspects of wireless performance and functionality, such as data rates, signal strength, security, and stability.
질문 # 101
In a split-MAC architecture, which functions are typically handled by the WLAN controller rather than the access point?
정답：C
설명：
In a split-MAC architecture, MAC layer functions are divided between the access point and the WLAN controller. Time-sensitive, real-time functions such as beacon generation, frame acknowledgment, and RTS/CTS handling remain at the access point, since they require very fast response times. Centralized, non-real-time functions, such as authentication, key management, RF channel and power management, and roaming coordination, are handled by the WLAN controller. This division allows for centralized policy control while keeping latency-sensitive operations local to the AP.
질문 # 102
What technology allows an access point to use multiple antennas to transmit and receive multiple spatial streams simultaneously, increasing throughput and reliability by taking advantage of multipath?
정답：C
설명：
Multiple-Input Multiple-Output (MIMO) technology uses multiple antennas at both the transmitter and receiver to send and receive multiple spatial streams of data simultaneously over the same channel. MIMO takes advantage of multipath propagation rather than being hindered by it, using techniques such as spatial multiplexing to increase throughput, and Maximal Ratio Combining along with Transmit Beamforming to improve reliability. MIMO was introduced with 802.11n and remains a core component of 802.11ac and 802.11ax.
질문 # 103
What statement about 802.3, Clause 33 Power over Ethernet is true?
정답：D
설명：
The statement that the lowest voltage drop is achieved when using CAT6 cable instead of Cat5 or CAT5e is true about 802.3, Clause 33 Power over Ethernet. Power over Ethernet (PoE) is a technology that allows electrical power to be delivered over Ethernet cables along with data signals. PoE is defined by IEEE 802.3, Clause 33 and has several variants, such as PoE (802.3af), PoE+ (802.3at), and PoE++ (802.3bt). PoE works by using a device called PSE (Power Sourcing Equipment) that injects power into the Ethernet cable and a device called PD (Powered Device) that receives power from the Ethernet cable. The PSE can be either an endpoint device, such as a switch or a router, or a midspan device, such as an injector or a splitter, that is inserted between two Ethernet devices. The PD can be any device that requires power, such as an access point, a camera, or a phone. One of the factors that affects PoE performance is voltage drop, which is the reduction of voltage that occurs as current flows through a cable due to its resistance. Voltage drop can cause power loss and inefficiency in PoE systems, as well as damage to PDs if the voltage falls below their minimum requirement. To minimize voltage drop, it is recommended to use high-quality cables with low resistance and short length. Among the common types of Ethernet cables, CAT6 has the lowest resistance and therefore the lowest voltage drop compared to Cat5 or CAT5e. CAT6 also has higher bandwidth and data rate than Cat5 or CAT5e, making it more suitable for PoE applications.
질문 # 104
A wireless engineer needs to calculate the total power radiated from an antenna, accounting for transmitter power, cable/connector losses, and antenna gain. What is this calculated value called?
정답：B
설명：
Effective Isotropic Radiated Power (EIRP) is the total amount of power that is effectively radiated from an antenna in the direction of maximum gain, calculated by taking the transmitter's output power, subtracting any losses from cables and connectors, and adding the antenna's gain. EIRP is an important calculation because regulatory bodies, such as the FCC, impose maximum EIRP limits for unlicensed WLAN devices to prevent excessive interference, and exceeding these limits without proper licensing is a regulatory violation.
