RUCKUS RCWA Dumps

When two access points operate onoverlapping channelsin the same frequency band—such aschannel 7 and channel 8in the 2.4 GHz range—they createAdjacent Channel Interference (ACI). Unlikeco-channel interference (CCI), which occurs when APs share the exact same channel,ACIresults from partial channel overlap that causes energy spillover between adjacent frequencies.

According toRUCKUS 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’sChannelFlytechnology in bothRUCKUS AIandRUCKUS Analyticshelps automatically select non-overlapping channels (such as 1, 6, and 11) to minimize ACI and optimize network capacity.

Therefore, the correct answer isA – Adjacent interference, which directly applies to overlapping channel configurations.

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).

RUCKUS Wi-Fi Planner (Wi-R Planner)is a predictive design tool that helps plan AP placement and coverage before physical deployment. It relies on environmental and hardware data to simulate accurate RF propagation.

According toRUCKUS One Online Help – Wi-Fi Planner Configuration, essential inputs include:

AP model selection (A):Determines transmit power, antenna gain, and coverage pattern.

Building wall materials (C):Define RF attenuation and signal propagation characteristics.

Parameters likeDHCP/DNS settingsorcontroller cluster sizeare not required for predictive modeling—they’re part of post-deployment configuration.

RUCKUS Analyticsis a cloud-based network intelligence platform integrated withRUCKUS Onethat providesservice-level assurance (SLA)andend-user experience visibilityacross multiple sites and networks.

According to theRUCKUS Analytics 3.5 User Guide, it leverages AI-driven baselines and telemetry data from access points and switches to:

Detect anomalies

Measure Wi-Fi performance against SLAs

Generate detailed client experience reports

SmartZone Essentialshandles local management,ZoneDirectoris legacy controller software, andSmartMeshis a wireless backhaul technology—not a management analytics system.

Innon-proxy RADIUS mode, theSmartZone controller does not act as an intermediaryfor authentication requests. Instead, eachaccess point (AP)communicatesdirectly with the RADIUS serverfor client authentication.

According toRUCKUS One Online Help – WLAN Authentication Modes (Proxy vs Non-Proxy), the key requirement is thateach AP must be defined as a RADIUS clientin 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 fromproxy mode, where only the SmartZone controller needs to be added as a RADIUS client. Port numbers (1812/1813) and encryption types remain standard, and both802.1XandMAC authenticationare supported.

Therefore, authentication failure in this scenario occurs becauseeach AP must be authorized individuallyin the RADIUS server when non-proxy mode is used.

In high-density environments such as stadiums or auditoriums,ceiling height and materialdirectly influencesignal propagation, attenuation, and AP coverage patterns.

As defined inRUCKUS One Online Help – High-Density Wi-Fi Design Guidelines, proper AP placement and downtilt must account for ceiling height and reflective surfaces to avoid co-channel interference and ensure sufficient SNR for every seat zone.

RUCKUS Wi-Fi Planner includes modeling tools for line-of-sight optimization and reflective surface analysis. DHCP and VLAN configurations affect logical segmentation but not physical RF propagation.

When configuring an802.1X-secured WLAN, RUCKUS systems such asSmartZone,RUCKUS One, orRUCKUS Cloudtypically rely on anexternal RADIUS serverfor user authentication. However, in the event of acontroller failure or connectivity loss to the RADIUS server,RUCKUS APs can continue to authenticate users locally if thelocal user databaseis enabled and configured.

TheLocal Authentication Databaseallows APs or controllers to store a limited set of credentials that can be used when external AAA services are unavailable. This ensurescontinued access and redundancyfor critical WLANs without requiring external dependency. According toRUCKUS One Online Help – WLAN Configuration and AAA Settings, enabling theLocal Authentication Databaseprovides fallback authentication for 802.1X clients during system or connectivity failures.

In contrast, theproxyandnon-proxymodes define how authentication requests are relayed to the RADIUS server, whileDynamic PSK (DPSK)is a separate authentication method that replaces 802.1X with per-user keys.

Expanding aVLAN Poolbeyond 32 VLANs in SmartZone requires access points that support the802.11ac Wave 2 standard or higher.

According toRUCKUS One Online Help – VLAN Pooling and Dynamic VLAN Assignment, older AP platforms (prior to 802.11ac Wave 2) are limited to 32 VLANs due to hardware constraints in VLAN ID indexing and memory allocation. Wave 2 and newer models (including Wi-Fi 6 and 6E APs) supportexpanded VLAN pools up to 64 or more entries.

This capability enables more granular segmentation of large user groups, especially in high-density enterprise or education environments where dynamic VLAN assignment distributes clients evenly across multiple subnets.

User roleandtraffic profileshandle authentication and QoS mapping, not VLAN scalability. 802.11k and 802.11r improve roaming, not VLAN allocation.

Therefore,802.11ac Wave 2 and abovehardware is required to support VLAN pools beyond 32 entries.

To maintainseamless client roamingin enterprise-grade Wi-Fi environments,RUCKUS recommends 20–25% signal overlapbetween adjacent AP coverage cells.

According toRUCKUS 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 Analysisconfirms 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.

AI Anomaly DetectioninRUCKUS Analyticsuses machine learning to detect, classify, and correlate service-impacting events such as authentication failures, RF interference, and backhaul latency.

According toRUCKUS Analytics 3.5 User Guide – AI-Driven Insights, this feature correlates telemetry across APs, clients, and switches to isolate root causes automatically. It identifies deviations from normal baselines and links related issues under unified incident reports.

RUCKUS One Online Help – Anomaly Detection and Correlation Engineconfirms this system dramatically reduces troubleshooting time by surfacing the exact source of network degradation.

Other tools likeEvent Timeline ViewerandHealth Dashboardvisualize events but do not perform automatic RCA (Root Cause Analysis).

SmartZone controllerssupport a range ofexternal authentication servicesfor bothproxy (via controller)andnon-proxy (direct-to-AAA)authentication mechanisms. According to theRUCKUS One Online Help – Authentication Services Configuration, the supported external services include:

Active Directory (AD) (A):Used for domain-based user authentication and group policy enforcement.

Lightweight Directory Access Protocol (LDAP) (B):Provides user authentication through directory lookup, commonly used for enterprise identity systems.

RADIUS (E):A widely used AAA protocol that integrates with external servers such as FreeRADIUS, Cisco ISE, or Microsoft NPS for centralized authentication and accounting.

WhileSAMLandOAuthare used inRUCKUS Cloud and RUCKUS Onefor SSO (Single Sign-On) and API authentication, they arenot used for WLAN or AAA authenticationwithin SmartZone.TACACS+is not supported as an external client authentication method in SmartZone (it is only used for admin login on some platforms).

Therefore, the correct authentication services areA (AD),B (LDAP), andE (RADIUS).

SmartCastis RUCKUS’s advancedQuality of Service (QoS)engine that prioritizes latency-sensitive traffic such asvoice, video, and real-time collaboration apps.

According toRUCKUS One Online Help – SmartCast OverviewandRUCKUS Analytics 3.5 User Guide – QoS Monitoring, SmartCast identifies traffic types usingDeep Packet Inspection (DPI)and applies802.1p/DSCP markingsto preserve QoS across wired and wireless segments.

It dynamically manages airtime scheduling and retransmissions to maintain low delay and jitter. Other features—likeBeamFlex+(antenna optimization) orChannelFly(channel selection)—do not handle traffic prioritization.

TheSmartZone Trace Toolenables administrators to capturepacket-level tracesfrom selected APs, clients, or controller interfaces to troubleshoot communication issues.

As defined inRUCKUS One Online Help – Trace and Packet Capture, this tool is used to analyze AP-to-controller join problems, authentication failures, or network latency conditions. Administrators specify theclient MACandassociated AP(s)to collect targeted trace logs.

RUCKUS Analytics 3.5 User Guide – Client Troubleshooting Sectionfurther notes that trace outputs can be downloaded as .pcap files for Wireshark analysis, providing detailed visibility into control-plane and data-plane interactions.

Other options serve different roles:AP Debug Modeprovides command-line diagnostics;Network Health Dashboardshows aggregated metrics;Cluster Diagnosticsassesses overall cluster health.

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 theR750andR850use 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.

ForVoice-over-Wi-Fi (VoWiFi)deployments, RUCKUS recommends maintainingairtime utilization under 50%and ensuring aminimum RSSI of –65 dBmat the edge of coverage areas to guarantee clear call quality and low latency.

According toRUCKUS One Online Help – WLAN Design for Real-Time ApplicationsandRUCKUS AI Documentation – VoIP Quality Optimization, these thresholds ensure aSignal-to-Noise Ratio (SNR)above 25 dB, keeping jitter under 30 ms and packet loss below 1%.

RUCKUSSmartCast QoSautomatically prioritizes voice packets (802.11e WMM Voice AC) to further protect call performance, but maintaining low channel congestion remains critical.

RUCKUS Analytics 3.5 User Guide – Airtime and Voice Traffic Metricsemphasizes monitoring airtime utilization through dashboards to verify compliance with design thresholds.

AnApplication Policyin SmartZone defines actions applied to identified applications or categories of traffic traversing a WLAN. UsingDeep Packet Inspection (DPI), RUCKUS APs recognize application types and enforce predefined behaviors.

According toRUCKUS One Online Help – Application Policy Configuration, the supported rule actions include:

(A) QoS:Assigns priority levels to traffic (Voice, Video, Best Effort, Background) for latency and throughput management.

(B) Deny:Blocks specific applications or categories (e.g., streaming or gaming) to preserve network performance.

(D) Rate Limit:Restricts bandwidth available to defined applications, ensuring fair use of airtime and bandwidth resources.

The exhibit shows avirtual SmartZone (vSZ)configuration running in a VMware environment withthree separate virtual NICs (vNICs), each mapped to a different port group:Management,Control, andCluster.

According toRUCKUS One Online Help – SmartZone Interface ConfigurationandRUCKUS AI Documentation – SmartZone High-Scale Architecture, this design is specific tovSZ-H (High-Scale)deployments, which requirethree distinct network interfacesfor distributed control, management, and cluster synchronization.

Thethree NIC mappingsconfirm physical or virtual separation of traffic for scalability and redundancy (AandE).vSZ-E(Essentials) requires onlytwo interfaces(Management and Control) and does not use a dedicated cluster interface, distinguishing it from vSZ-H (D).

There is no indication of a four-node cluster in the exhibit, and SmartZone appliances typically show node counts under the Cluster Dashboard, not at the NIC configuration stage.

Thus, based on the configuration, this is avSZ-Hsystem withthree NICs and three port groups, each serving a dedicated function.

TheIEEE 802.11kamendment enhances Wi-Fi client roaming by allowing an AP to share information about nearby access points with connected clients. This process, known as theNeighbor Report, provides alist of available APsthat the client can use to make faster, more informed roaming decisions.

When a client device receives this neighbor list, it canscan fewer channels, reducing latency and improving the handoff experience—especially in enterprise networks managed byRUCKUS One,SmartZone, orRUCKUS Cloud. According toRUCKUS One Online HelpandRUCKUS AI documentation, enabling802.11k/v/rfeatures together allows forfast and seamless roaming, as 802.11k supplies discovery data, 802.11v assists with steering decisions, and 802.11r enables fast re-authentication.

OptionCis correct because 802.11k’s core function is to help clients identify the best potential APs to roam to. The other options describe unrelated functions: encryption caching relates to 802.11r, ignoring weak clients is an AP policy function, and forcing disconnections occurs during load balancing or steering—not through 802.11k.

TheData Interfaceis unique tophysical SmartZone (SZ) hardware appliancessuch as theSmartZone 100 (SZ-100)orSmartZone 300 (SZ-300). This interface handlesuser traffic data forwardingin hardware-based deployments and isnot presentin virtualized versions such as thevSZ (Virtual SmartZone).

According to theRUCKUS One Online HelpandSmartZone system architecture descriptions, the physical controller includes four main interfaces:

Management Interface:Handles GUI, CLI, and administrative access.

Control Interface:Manages control-plane communications with access points.

Cluster Interface:Manages synchronization and redundancy between cluster members.

Data Interface:Dedicated for data-plane traffic processing and forwarding (exclusive to physical appliances).

Virtual SmartZone controllers usetunnel-based data forwarding(via GRE or VXLAN) instead of a dedicated hardwareData Interface. Hence, theData interfaceexists only on physical appliances, makingAthe correct answer.

When enabling802.1X authenticationon a RUCKUSAccess Portvia anEthernet Port Profile(used for ICX switches or AP wired interfaces), the available roles are:

(A) Supplicant:The device (AP or switch port) acts as the client that must authenticate to the upstream authenticator (e.g., a switch or NAC system).

(C) Port-based Authenticator:The device enforces 802.1X authentication for devices connected to it (e.g., a switch controlling a connected host).

According toRUCKUS One Online Help – 802.1X and Wired Authentication ConfigurationandRUCKUS Analytics 3.5 User Guide – Wired Client Authentication Monitoring, these two roles define whether the port initiates or enforces authentication.

“Host-based” and “MAC-based” refer to specific authenticationmethods, notroles, and “Authentication Server” (e.g., RADIUS) is an external entity, not a port role.

ASmartZone cluster backupis a comprehensive backup of the controller cluster’s system and configuration data, intended for disaster recovery or migration to similar SmartZone platforms. According to theRUCKUS One Online Help – Cluster Backup and RestoreandSmartZone Administration Guide (v5.2+), a cluster backup includes:

Cluster and controller configuration, including IP addressing, zones, AP groups, WLANs, and policies.

Client statistical data and historical analytics, which are also captured for restoration of system monitoring data.

When a cluster backup is initiated,the controller enters maintenance modeto ensure database consistency and prevent configuration changes during the process. This temporarily suspends management operations but preserves data integrity.

Cluster backupscannot be restored to different SmartZone models(e.g., vSZ to SZ-100) due to hardware and licensing differences. Backups alsorequire system services to be activeduring execution.

Therefore, the correct answers areB(contains IP addressing and client statistical information) andD(puts the controller into maintenance mode when executed).

In this SmartZone 5.2 onboarding scenario:

San Mateo (200.7.10.202.121):These APs are runningUnleashed firmware, which cannot directly join a SmartZone controller. According to theRUCKUS One Online Help – AP Firmware Migration, Unleashed APs must first be converted toStandalone (Solo) modeusing CLI (set director ip or set scg ip) before they can connect. Thus,D (San Mateo devices can use ap-mode commands to onboard)is correct.

Toronto (102.0.0.0.5):This firmware version representsZoneDirector (ZD)code. APs on ZD firmware communicate usingLWAPP, and to migrate them, administrators must perform a firmware conversion process (using set scg ip) for SmartZone compatibility. Therefore,E (Toronto devices will use LWAPP to communicate to SmartZone)is correct.

Mexico City (5.2.0.0.1412):These APs already match the SmartZone firmware family (5.2.x), meaning they are currently or can immediately be managed by this SmartZone cluster. Therefore,Fis correct.

TheSmartZone Trace Toolis used to capture and analyze packets related to specific client connectivity sessions, helping administrators identify association, authentication, and DHCP issues.

According toRUCKUS One Online Help – Troubleshooting Tools and Packet CaptureandRUCKUS Analytics 3.5 User Guide – Client Connectivity Tracing, the following two pieces of information are required to initiate a trace:

Client MAC Address (C):Identifies the exact device on the network to filter relevant packet captures and session details.

Correct AP(s) to select (D):Specifies the access point(s) currently or recently serving that client, ensuring the trace targets the correct radio interface for capturing traffic.

Other details likedevice name,AP model, orclient OSare useful for contextual understanding but not required inputs for running the trace. The trace tool uses these two core identifiers to isolate logs and generate capture data efficiently for troubleshooting connectivity issues.
