質問 # 33
An admin has configured a non-proxy RADIUS authentication server and applied it to a WLAN. Which state explains why user authentication is failing?
- A. Non-proxy only works with 802.1X authentication.
- B. Non-proxy authentication requires use of standard ports.
- C. Non-proxy requires a unique shared secret.
- D. Each AP needs to be a RADIUS client.
正解：D
解説：
In non-proxy RADIUS mode, the SmartZone controller does not act as an intermediary for authentication requests. Instead, each access point (AP) communicates directly with the RADIUS server for client authentication.
According to RUCKUS One Online Help - WLAN Authentication Modes (Proxy vs Non-Proxy), the key requirement is that each AP must be defined as a RADIUS client in the RADIUS server configuration. If not, authentication requests from the APs are rejected because the server does not recognize their source IPs or shared secrets.
This behavior differs from proxy mode, where only the SmartZone controller needs to be added as a RADIUS client. Port numbers (1812/1813) and encryption types remain standard, and both 802.1X and MAC authentication are supported.
Therefore, authentication failure in this scenario occurs because each AP must be authorized individually in the RADIUS server when non-proxy mode is used.

質問 # 35
Which type of interference occurs when two APs are configured on channel 7 and channel 8 in the same physical space?
- A. Diffraction
- B. Adjacent
- C. Multipath
- D. Co-channel
正解：B
解説：
When two access points operate on overlapping channels in the same frequency band-such as channel 7 and channel 8 in the 2.4 GHz range-they create Adjacent Channel Interference (ACI). Unlike co-channel interference (CCI), which occurs when APs share the exact same channel, ACI results from partial channel overlap that causes energy spillover between adjacent frequencies.
According to RUCKUS One Online Help - Radio Configuration and Channel Planning, adjacent channels in 2.4 GHz are only 5 MHz apart, while each Wi-Fi channel occupies 20-22 MHz of bandwidth. As a result, channels like 7 and 8 significantly overlap, creating degraded performance, retransmissions, and reduced throughput.
RUCKUS's ChannelFly technology in both RUCKUS AI and RUCKUS Analytics helps automatically select non-overlapping channels (such as 1, 6, and 11) to minimize ACI and optimize network capacity.
Therefore, the correct answer is A - Adjacent interference, which directly applies to overlapping channel configurations.

- A. Institute of Electrical and Electronics Engineers (IEEE)
- B. International Standards Organization (ISO)
- C. Internet Engineering Task Force (IETF)
- D. Wi-Fi Alliance
正解：D
解説：
The Wi-Fi Alliance (WFA) is the global organization responsible for testing and certifying interoperability of wireless LAN products based on the IEEE 802.11 standards. While the IEEE develops and maintains the technical specifications (e.g., 802.11a/b/g/n/ac/ax), it does not perform certification or compliance testing. Instead, the Wi-Fi Alliance ensures that certified devices from different manufacturers operate together seamlessly under the "Wi-Fi CERTIFIED™" program.
According to RUCKUS One Online Help and the RUCKUS AI documentation, RUCKUS access points and controllers undergo Wi-Fi Alliance certification to ensure compatibility with a wide range of client devices, including those using WPA3, Wi-Fi 6 (802.11ax), and Wi-Fi 6E technologies. This certification is critical for enterprise environments where heterogeneous client ecosystems exist.
The IETF focuses on internet protocols (e.g., IP, TCP), and the ISO handles broader international standards, not wireless interoperability. Therefore, the Wi-Fi Alliance is the correct organization ensuring cross-vendor interoperability for Wi-Fi.

- A. QAM256
- B. RTS/CTS
- C. MU-MIMO
- D. OFDMA
正解：D
解説：
OFDMA (Orthogonal Frequency Division Multiple Access)is one of the core features introduced inIEEE
802.11ax (Wi-Fi 6). It divides a channel into smaller subcarriers calledResource Units (RUs), allowing an AP to communicate with multiple clients simultaneously, both on uplink and downlink.
According to theRUCKUS One Online Help - Wi-Fi 6 Features Overview, OFDMA improves spectrum efficiency, reduces latency, and increases throughput in high-density environments. RUCKUS APs such as the R750andR850use OFDMA in coordination withRUCKUS AI's client traffic analysisto allocate resources dynamically.
In contrast,MU-MIMOalso supports multi-user communication but only in one direction (downlink for

- A. vSZ-E
- B. RUCKUS Cloud
- C. Unleashed
- D. vSZ-H
正解：D
解説：
Partner Domains are specific to the Virtual SmartZone - High Scale (vSZ-H) management platform. This feature is designed to provide multi-tenancy support for managed service providers (MSPs) and large enterprises managing multiple organizations under a single SmartZone instance.
As defined in the RUCKUS One Online Help - SmartZone Multi-Tenant Management, Partner Domains allow administrators to create separate logical domains, each with its own system administrators, policies, and reporting. This enables service providers to host multiple customers securely on the same vSZ-H infrastructure without sharing configuration or visibility across domains.
The vSZ-E (Essentials) version does not support Partner Domains because it is intended for single-tenant environments. Unleashed and RUCKUS Cloud provide simpler management for smaller deployments and inherently separate tenants by account, not by Partner Domain.
Therefore, B (vSZ-H) is the correct answer.

- A. It does not require supported client drivers.
- B. It increases radio Tx power.
- C. It eliminates channel interference.
- D. It eliminates hardware PHY errors.
正解：A
解説：
RUCKUS BeamFlex+is an advanced adaptive antenna technology that dynamically selects from thousands of possible antenna patterns to optimize signal quality and performance for each client connection. Unlike Transmit Beamforming (TxBF), which depends on feedback from client devices that must support specific beamforming protocols,BeamFlex+ operates entirely on the access point side.
The key advantage of BeamFlex+ is thatit does not require any client-side support or compatible drivers.
It continuously analyzes signal characteristics and client locations to select the optimal antenna pattern in real time, enhancing both range and throughput without additional client configuration.
According to theRUCKUS One Online HelpandRUCKUS AI documentation, BeamFlex+ combines adaptive antenna pattern selectionwithpolarization diversity (PD-MRC)to improve performance in dynamic environments. In contrast,Tx Beamformingrequires explicit feedback (channel state information) from clients-limiting its effectiveness when clients lack driver or chipset compatibility.
Thus, the correct answer isD, as BeamFlex+ provides all the benefits of adaptive beamforming without the need for client-side dependencies.

Using the rule of 10s and 3s, how many mW does 23 dBm convert to?
- A. 250 mW
- B. 225 mW
- C. 200 mW
- D. 150 mW
正解：C
解説：
TheRule of 10s and 3sis a quick mental calculation used to convert betweendBm (decibel-milliwatts)and milliwatts (mW), which represent power levels. The rule states that:
* Every10 dB increasecorresponds to a10× increase in power.
* Every3 dB increasecorresponds to approximately a2× increase in power.
Starting from0 dBm = 1 mW:
* +10 dBm = 10 mW
* +20 dBm = 100 mW
* Add 3 dB # 23 dBm = 100 mW × 2 #200 mW
Thus,23 dBm converts to approximately 200 mW. This principle is used throughout RUCKUS documentation for understandingEIRP (Effective Isotropic Radiated Power)and ensuring compliance with regulatory transmit power limits.
According toRUCKUS One Online HelpandRUCKUS AI user documentation, administrators often use this conversion when optimizing transmit power settings to balance coverage and interference. The rule helps design engineers translate dB settings into physical power outputs during Wi-Fi tuning and planning.

TheNoise Floor Levelrepresents the background RF interference in dBm, which directly affects theSignal-to- Noise Ratio (SNR)and overall connection stability.
As stated inRUCKUS One Online Help - RF Diagnostics, an elevated noise floor (e.g., higher than -85 dBm) can indicate interference from devices such as wireless cameras or radar systems.
