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).

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).

InRUCKUS Wi-Fi Planner, definingattenuation valuesfor wall materials enables the simulation ofRF signal lossacross physical barriers such as drywall, concrete, or glass.

According toRUCKUS One Online Help – Wi-Fi Planner RF Modeling, accurate wall attenuation data allows the planner to predict signal propagation and coverage maps with greater accuracy. This ensures optimal AP placement and reduces coverage overlap or dead zones.

TheRUCKUS Analytics 3.5 User Guide – RF Validation Reportsconfirms that modeling real-world materials provides reliable pre-deployment visibility of expected SNR and throughput performance.

Other options—like RSSI thresholds or DHCP zoning—are not part of RF prediction modeling.

Designing Wi-Fi forLarge Public Venues (LPV)such as stadiums, arenas, or convention centers requires a highly strategic RF approach to handleextreme client densityanddynamic environmental factors.

According toRUCKUS One Online Help – High-Density Design Best PracticesandRUCKUS AI Documentation – LPV Deployment Planning, three critical considerations are:

Expected number of devices (B):Determines AP count, bandwidth capacity, and airtime utilization. LPV environments often exceed one device per seat, requiring precise capacity planning.

Effect of human bodies on RF propagation (D):Human absorption of 2.4 GHz and partial reflection of 5 GHz signals dramatically affects coverage. RUCKUS recommends directional antennas and elevated AP placement to overcome this.

Versions of iOS and Android (F):Client device capability (e.g., Wi-Fi 5/6 support, roaming features) influences channel width, band steering, and roaming design.

Other factors like WAN speed and charging stations are operational but not primary design variables in LPV RF engineering.

Admin DomainsinSmartZoneproviderole-based access control (RBAC)by dividing system management into separate administrative scopes. Each Admin Domain can contain specific zones, WLANs, and devices, with access limited to assigned administrators.

As outlined inRUCKUS One Online Help – Administrative Domains and Roles, this feature enables organizations or MSPs to securely delegate management tasks to different teams or customers while maintaining full isolation between configurations.

Partner Domainsexist only in vSZ-H (multi-tenant environments), whileCluster Rolesmanage global system functions.AP Groupsare configuration containers but not access control boundaries.

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.

Local BreakoutandVLAN Assignmentare functions oftraffic forwardinganddevice policy, not application policy.URL filteringis managed under separatecontent controlmodules, not part of Application Policies.

For optimalvoice and video performance, RUCKUS recommends maintaining aSignal-to-Noise Ratio (SNR)of25 dB or higherto ensure a clear, low-latency wireless link.

According toRUCKUS One Online Help – Wi-Fi Quality and SNR ThresholdsandRUCKUS AI Documentation – VoIP and Streaming Application Optimization, SNR values above 25 dB correspond to high modulation and coding schemes (MCS8–MCS11 in Wi-Fi 6), supporting stable throughput with minimal jitter or packet loss.

The exhibit shows that theBoardroommaintains an SNR of28 dB, which exceeds the recommended 25 dB threshold, making it ideal forHD video conferencing and VoIPapplications.

Other areas (Office, Breakroom, Warehouse) fall below optimal levels, which can lead to voice dropouts, jitter, and reduced data rates.

RUCKUS Analytics 3.5 User Guide – Client Experience Metricsfurther validates SNR as a key indicator of real-time application quality.

RUCKUS Analyticsprovideshistorical and AI-driven insightsinto network health and client connectivity trends. It identifieschronic connectivity issues, such as repeated association failures, high retry rates, or roaming delays, over extended timeframes.

According to theRUCKUS Analytics 3.5 User Guide – Client Troubleshooting and Service Assurance, the platform uses machine learning to analyze large volumes of telemetry data from APs, automatically flagging recurring issues per client or SSID.

TheSmartZone Trace Toolcaptures short-term packet traces, whileCluster DiagnosticsandSmartMesh Dashboardfocus on infrastructure health—not client behavior.

TheWi-Fi Alliance (WFA)is the global organization responsible fortesting and certifying interoperabilityof wireless LAN products based on the IEEE 802.11 standards. While theIEEEdevelops and maintains the technical specifications (e.g., 802.11a/b/g/n/ac/ax), it doesnotperform 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 toRUCKUS One Online Helpand theRUCKUS 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.

TheIETFfocuses on internet protocols (e.g., IP, TCP), and theISOhandles broader international standards, not wireless interoperability. Therefore, theWi-Fi Allianceis the correct organization ensuring cross-vendor interoperability for Wi-Fi.

TheWireless Intrusion Prevention System (WIPS)in SmartZone continuously monitors the RF environment to detect and mitigate rogue or malicious behavior.

According toRUCKUS One Online Help – WIPS Policy Configuration, availablerule typesinclude:

(B) High RSSI:Detects potentialrogue APs or clientsbroadcasting at unusually strong signal levels that suggest proximity or spoofing attempts.

(C) NAV Abuse:Identifies devices misusing theNetwork Allocation Vectorfield to monopolize airtime, degrading performance for other users.

(E) SSID Spoofing:Detects devices broadcasting identical SSIDs to legitimate WLANs, often used in man-in-the-middle or phishing attacks.

Other listed options, such asShort GI (Guard Interval)andSame Network, are PHY or configuration settings, not WIPS rules.Excessive Powerdetection is handled indirectly viaHigh RSSIthresholds.
