Background Scanningin RUCKUS APs allows radios to periodically scan other channels to collect RF environment data while still serving clients. The scan interval determines how often the AP samples channel information for features likeChannelFly,Auto Cell Sizing, androgue detection.
According toRUCKUS One Online Help - Background Scanning and RF Management, andRUCKUS Analytics 3.5 User Guide - RF Monitoring, increasing theBackground Scanning intervalto90 seconds delays updates for processes that depend on real-time RF sampling, specifically:
* Rogue AP Detection (B):Takes longer to discover unauthorized or neighboring APs.
* Auto-Channel Selection (C):Updates channel quality metrics less frequently, slowing responsiveness to interference changes.
* Auto Power Adjustment (E):Depends on scanning results to optimize transmit power for coverage balance, so adjustments occur less frequently.
Processes such asclient countandthroughput measurementrely on active client data, not background scanning, andspectrum analysisoperates in a dedicated analysis mode outside of normal scanning intervals.

Chanalyzeris a specialized RF spectrum analysis tool developed for use with Wi-Spy spectrum analyzers. It is used tovisualize and validate Wi-Fi and non-Wi-Fi interference sourcesacross the 2.4 GHz and 5 GHz bands.
According to theRUCKUS 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-inspectrum analysis mode, Chanalyzer providesexternal, high-resolution spectrum visualizationthat helps confirm interference sources in physical environments.
In contrast,RUCKUS Wi-Fi Planner(orWi-R Planner) is used for predictive RF design and coverage estimation, not live interference detection. TheWLAN discovery toolidentifies SSIDs and basic network parameters but cannot detect non-Wi-Fi signals.
Therefore, the correct answer isD (Chanalyzer)- the standard tool for verifying valid Wi-Fi operation and identifying non-Wi-Fi interference sources.

SmartCast is RUCKUS's advanced Quality of Service (QoS) engine that prioritizes latency-sensitive traffic such as voice, video, and real-time collaboration apps.
According to RUCKUS One Online Help - SmartCast Overview and RUCKUS Analytics 3.5 User Guide - QoS Monitoring, SmartCast identifies traffic types using Deep Packet Inspection (DPI) and applies 802.1p/DSCP markings to preserve QoS across wired and wireless segments.
It dynamically manages airtime scheduling and retransmissions to maintain low delay and jitter. Other features-like BeamFlex+ (antenna optimization) or ChannelFly (channel selection)-do not handle traffic prioritization.

To throttle download speeds for specific device types-such as ChromeOS devices-and assign them to a dedicated VLAN, the appropriate configuration is to create a Device Policy and apply it to the target WLAN.
According to the RUCKUS One Online Help - Device Policy Management, and RUCKUS AI documentation - Policy Control and Device Analytics, Device Policies can classify client devices based on operating system, MAC OUI, or fingerprinting data. Once identified, administrators can enforce rate limits, VLAN tagging, and access restrictions for that device type.
By applying this policy to the STUDENT SSID, all detected ChromeOS clients will have bandwidth limits applied and their traffic segmented into the configured VLAN for management and security isolation.
Other options-such as Layer 2 ACLs or Application Control Policies-manage packet-level permissions or app-level prioritization, not per-device bandwidth or VLAN segmentation. Creating a new WLAN is unnecessary since RUCKUS policy management allows dynamic device-based enforcement on a single SSID.

To maintain seamless client roaming in enterprise-grade Wi-Fi environments, RUCKUS recommends 20-25% signal overlap between adjacent AP coverage cells.
According to RUCKUS One Online Help - Roaming and Coverage Design Guidelines, this overlap ensures clients maintain an adequate RSSI and SNR threshold during roaming events without coverage gaps.
RUCKUS Analytics 3.5 User Guide - Client Mobility Analysis confirms that insufficient overlap often leads to disconnects or sticky-client behavior, while excessive overlap increases co-channel interference.
This guideline applies across 2.4 GHz and 5 GHz deployments, ensuring smooth transitions for 802.11r/k/v-enabled clients.
