RUCKUS Updated RCWA Exam Questions and Answers by elsie-rose

In non-proxy RADIUS mode , the SmartZone controller does not act as an intermediary for authentication requests. Instead, each access point (AP) communicates directly with the RADIUS server for client authentication.

According to RUCKUS One Online Help – WLAN Authentication Modes (Proxy vs Non-Proxy) , the key requirement is that each AP must be defined as a RADIUS client in 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 from proxy mode , where only the SmartZone controller needs to be added as a RADIUS client. Port numbers (1812/1813) and encryption types remain standard, and both 802.1X and MAC authentication are supported.

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

The Client Isolation feature on RUCKUS access points and controllers prevents wireless clients connected to the same SSID from communicating directly with each other within the same subnet. This is particularly important for guest or public networks to enhance security and privacy. However, administrators may sometimes need to allow access to specific network services or devices—such as printers, gateways, or media servers—within that same subnet.

RUCKUS systems address this need through the Isolation Whitelist capability. As described in the RUCKUS One Online Help and RUCKUS Cloud documentation , the Isolation Whitelist allows administrators to specify destination IP or MAC addresses that are exempt from client isolation rules. This enables controlled access without fully disabling client isolation across the network.

Other options like directed multicast or access control list (ACL) manage traffic types or filtering policies but are not specific to client-to-client communication exceptions. Therefore, the Isolation Whitelist is the correct answer.

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.

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 to RUCKUS 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 like DHCP/DNS settings or controller cluster size are not required for predictive modeling—they’re part of post-deployment configuration.
