ChannelFlyis RUCKUS's machine learning-baseddynamic channel selectiontechnology. It evaluates real- timethroughputon each channel rather than relying only onnoise or interference metricsto determine the best operating channel.
As outlined inRUCKUS One Online Help - ChannelFly OperationandRUCKUS AI Documentation - Channel Optimization, ChannelFly continuously monitors channel conditions and switches to those offering higher capacity.
This ensures maximum real-world performance, especially in dense environments with unpredictable interference.
BeamFlex+adjusts antenna patterns,SmartCastprioritizes traffic, andPD-MRCenhances signal reception but do not handle channel learning or selection.

RUCKUS indoor Access Points usestatus LEDsto communicate key operational states during deployment and runtime. The LEDs provide immediate visual feedback about the AP's connectivity, power condition, and client activity.
According to theRUCKUS One Online Help - Access Point LED Indicators, and verified in theRUCKUS AI documentation, the LEDs typically display the following primary states:
* Controller Connected (A):Confirms that the AP has successfully registered and established a control session with the RUCKUS controller or RUCKUS Cloud instance.
* Insufficient PoE Power (C):Indicates that the AP is receiving inadequate power, such as being powered through 802.3af instead of 802.3at, which may disable high-power features or additional radios.
* Clients Connected to a Radio (D):Lights up when one or more clients are associated with the AP's wireless radios, signifying active WLAN operation.
Other listed options-USB dongle inserted,data plane tunnel connected, androutable IP assigned-are not standard LED indications across RUCKUS indoor AP models. They may represent system events but not physical LED states.

AnEthernet Port ProfileinSmartZonedefines wired interface behavior and port settings for access points that have multiple Ethernet ports. These profiles are used to configure connectivity, security, and redundancy on wired links between APs and the upstream network.
According to theRUCKUS One Online Help - AP Ethernet Port ProfilesandSmartZone 5.x Configuration Guide, the following parameters are supported:
* Port Speed (A):Defines link negotiation-Auto, 10/100/1000 Mbps, or fixed rate.
* Spanning Tree Mode (D):Controls loop prevention through STP configuration on AP Ethernet ports.
* 802.1X Authentication (E):Enables port-based authentication for secure wired access on AP Ethernet interfaces, commonly used in hospitality and MDU deployments.
Other listed options-LAG creation(handled via controller-side link aggregation configuration),number of clients(a WLAN-level setting), andTunnel Profile selection(handled under WLAN or Zone configuration)- are not part of the Ethernet Port Profile feature.
Thus, the correct answers areA (Port speed),D (Spanning Tree mode), andE (802.1X Authentication).

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
802.11ac Wave 2, both for 11ax).QAM256enhances modulation efficiency but doesn't enable concurrent multi-client service.

Chanalyzer is a specialized RF spectrum analysis tool developed for use with Wi-Spy spectrum analyzers. It is used to visualize and validate Wi-Fi and non-Wi-Fi interference sources across the 2.4 GHz and 5 GHz bands.
According to the RUCKUS One Online Help - Spectrum Analysis and RF Interference Tools, spectrum analysis tools like Chanalyzer can detect non-802.11 interference sources such as microwave ovens, Bluetooth devices, DECT phones, and radar signals. While RUCKUS APs have built-in spectrum analysis mode, Chanalyzer provides external, high-resolution spectrum visualization that helps confirm interference sources in physical environments.
In contrast, RUCKUS Wi-Fi Planner (or Wi-R Planner) is used for predictive RF design and coverage estimation, not live interference detection. The WLAN discovery tool identifies SSIDs and basic network parameters but cannot detect non-Wi-Fi signals.
Therefore, the correct answer is D (Chanalyzer) - the standard tool for verifying valid Wi-Fi operation and identifying non-Wi-Fi interference sources.
