RUCKUS RCWA Exam Dumps

Seamless roaming on RUCKUS WLANs is achieved through support for 802.11k, 802.11r, and 802.11v enhancements, which collectively improve handoff efficiency and reduce latency when clients move between APs.

According to RUCKUS One Online Help -- Fast Roaming Configuration and RUCKUS AI Documentation -- Client Mobility Optimization, the following statements are true:

802.11k (C): Enables APs to provide Neighbor Reports listing surrounding APs and their channels, allowing clients to make faster and more intelligent roaming decisions.

802.11r (D): Implements Fast BSS Transition (FT), reducing authentication delay during roaming by pre-establishing encryption keys. However, its operation depends on the encryption type---it is supported only with WPA2-Enterprise (802.1X) and WPA2/WPA3-Personal modes, not open WLANs.

The other options are incorrect: 802.11ac aggregation does not affect roaming; 802.11u supports Hotspot 2.0, not fast transition; and 802.11w (PMF) adds management frame protection, not roaming enhancements.

Thus, the correct answers are C (802.11k neighbor lists) and D (802.11r depends on encryption type).

RSSI (Received Signal Strength Indicator) is a key measurement representing the power level of a received RF signal. It is typically displayed in dBm (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 the RUCKUS One Online Help and the RUCKUS Analytics 3.5 User Guide, signal strength metrics shown in dashboards, client views, and RF reports are represented in dBm for 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 as dBi refer to antenna gain, Watts measure absolute power (not typically used in client reporting), and Ohms measure resistance. Thus, dBm is the correct and standard unit used for RSSI measurement in RUCKUS and all IEEE 802.11-based systems.

SmartCast is RUCKUS's patented traffic classification and Quality of Service (QoS) technology. It dynamically prioritizes network packets based on type, marking delay-sensitive applications such as voice or video for prioritized transmission.

Per RUCKUS One Online Help -- SmartCast Traffic Prioritization, SmartCast identifies traffic categories using Deep Packet Inspection (DPI) and applies corresponding 802.1p/DSCP markings across wired and wireless segments.

This ensures consistent service quality for time-sensitive applications even during network congestion. BeamFlex+, PD-MRC, and ChannelFly operate at the RF level and do not manage traffic prioritization or QoS policies.

The SmartZone CLI command get scg provides detailed information about an AP's connection to its controller.

From the output provided:

The ''State: RUN_STATE'' line confirms the AP is fully connected, accepted, and managed by the controller (E). If the AP were pending, it would display ''JOIN_STATE'' or ''CFG_STATE.''

The presence of two controller IPs and an SSH tunnel connection to 10.1.1.245 indicates a control-plane tunnel established via NAT traversal, meaning the controller is behind a control NAT IP (D).

The ''Controller Cert Validation: disable'' line shows certificate validation is off, but it doesn't affect operational state. The Server List confirms 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.

RUCKUS indoor Access Points use status LEDs to 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 the RUCKUS One Online Help -- Access Point LED Indicators, and verified in the RUCKUS 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, and routable IP assigned---are not standard LED indications across RUCKUS indoor AP models. They may represent system events but not physical LED states.
