Free Practice Questions for RUCKUS RCWA Exam

TheSmartZone CLI command get scgprovides detailed information about an AP’s connection to its controller.

From the output provided:

The“State: RUN_STATE”line confirms the AP is fullyconnected, accepted, and managedby the controller (E). If the AP were pending, it would display “JOIN_STATE” or “CFG_STATE.”

Thepresence of two controller IPsand anSSH tunnel connection to 10.1.1.245indicates a control-plane tunnel established via NAT traversal, meaning the controller isbehind a control NAT IP(D).

The “Controller Cert Validation: disable” line shows certificate validation is off, but it doesn’t affect operational state. TheServer Listconfirms static IP discovery rather than DNS-based assignment.

Thus, the AP is active and managed by the controller, with communication handled through an SSH-based control tunnel.

In this layout, the indoor APs are centrally mounted to provide even signal distribution in all directions, while outdoor APs are wall-mounted facing the exterior coverage zone.

According toRUCKUS One Online Help – Antenna Selection and DeploymentandRUCKUS AI Documentation – RF Design Guidelines, the best configuration for complete coverage is:

Indoor space:UseOmni-Directional antennas, which radiate uniformly in 360° for even indoor coverage and minimal dead zones.

Outdoor space:UsePatch antennas, which aresemi-directionalwith a 60°–90° beamwidth ideal for covering patios, courtyards, or building perimeters without wasting signal behind the AP.

Yagi antennasare highly directional and suited for long-distance point-to-point links, not area coverage.Semi-directional indoor antennasare unnecessary unless indoor partitioning or wall density requires focused energy.

This combination—Omni indoorsandPatch outdoors—provides optimal performance for mixed indoor-outdoor designs and aligns withRUCKUS high-density deployment best practices.

RSSI (Received Signal Strength Indicator)is a key measurement representing the power level of a received RF signal. It is typically displayed indBm (decibel-milliwatts), a logarithmic unit that expresses the power relative to 1 milliwatt. In Wi-Fi systems, RSSI values usually range between–30 dBm (excellent)and–90 dBm (very weak).

According to theRUCKUS One Online Helpand theRUCKUS Analytics 3.5 User Guide, signal strength metrics shown in dashboards, client views, and RF reports are represented indBmfor consistency across platforms. This allows network engineers to correlate signal levels with client connectivity performance and thresholds used for roaming or troubleshooting.

Other units such asdBirefer to antenna gain,Wattsmeasure absolute power (not typically used in client reporting), andOhmsmeasure resistance. Thus,dBmis the correct and standard unit used for RSSI measurement in RUCKUS and all IEEE 802.11-based systems.

Image ManagementinSmartZoneautomates the firmware upgrade process for APs, ensuring consistent software versions across all zones and AP models.

As detailed inRUCKUS One Online Help – Image Management and Firmware Control, administrators can upload, assign, and schedule firmware images by zone. The system automatically validates version compatibility before deployment to prevent mismatched or unsupported upgrades.

RUCKUS Analytics 3.5 User Guide – Firmware Compliance Monitoringconfirms that this ensures version uniformity across large distributed networks.

Options likeZone Upgrade SchedulerandAP Provisioning Policyare part of related workflows but not the primary feature controlling image management.

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.

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.

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.

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.

Maintaininglow airtime utilizationis key to achieving high efficiency and performance in Wi-Fi networks. RUCKUS recommends minimizing factors that increase channel contention and protocol overhead.

PerRUCKUS One Online Help – Airtime Management and OptimizationandRUCKUS AI Documentation – Channel Utilization Insights, the following actions are most effective:

(A) Limiting older/legacy clients:802.11a/b/g clients transmit at lower rates and occupy more airtime per packet.

(D) Ensuring sufficient AP capacity for clients:Proper AP density ensures users are distributed evenly, reducing per-AP contention.

(F) Mitigating non-802.11 interference:Removing microwave ovens, Bluetooth devices, and other RF noise sources prevents wasted airtime from retries.

Adding more SSIDs (WLANs) increases management frame overhead, and full transmit power causes excessive cell overlap—both raise airtime use.

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.
