Answer : C

Band Steering is a RUCKUS feature designed to guide dual-band capable clients toward the 5 GHz band, which generally provides better performance and less interference than 2.4 GHz.

As described in RUCKUS One Online Help -- Band Steering Configuration and RUCKUS AI Documentation -- Client Connectivity Optimization, when a client attempts to connect, the AP temporarily delays responses to 2.4 GHz probes, encouraging the client to associate on 5 GHz.

This feature enhances airtime efficiency and reduces congestion in dense environments. Band Balancing distributes clients between APs, while SmartCast and ChannelFly manage QoS and channel optimization, respectively.

SmartZone controllers support a range of external authentication services for both proxy (via controller) and non-proxy (direct-to-AAA) authentication mechanisms. According to the RUCKUS 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.

While SAML and OAuth are used in RUCKUS Cloud and RUCKUS One for SSO (Single Sign-On) and API authentication, they are not used for WLAN or AAA authentication within 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 are A (AD), B (LDAP), and E (RADIUS).

Answer : B

In high-density environments such as stadiums or auditoriums, ceiling height and material directly influence signal propagation, attenuation, and AP coverage patterns.

As defined in RUCKUS 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.

Answer : A, C

When enabling 802.1X authentication on a RUCKUS Access Port via an Ethernet 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 to RUCKUS One Online Help -- 802.1X and Wired Authentication Configuration and RUCKUS 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 authentication methods, not roles, and ''Authentication Server'' (e.g., RADIUS) is an external entity, not a port role.

Answer : A

To throttle download speeds for specific device types---such as ChromeOS devices---and assign them to a dedicated VLAN, the appropriate configuration is to create a Device Policy and apply it to the target WLAN.

According to the RUCKUS One Online Help -- Device Policy Management, and RUCKUS AI documentation -- Policy Control and Device Analytics, Device Policies can classify client devices based on operating system, MAC OUI, or fingerprinting data. Once identified, administrators can enforce rate limits, VLAN tagging, and access restrictions for that device type.

By applying this policy to the STUDENT SSID, all detected ChromeOS clients will have bandwidth limits applied and their traffic segmented into the configured VLAN for management and security isolation.

Other options---such as Layer 2 ACLs or Application Control Policies---manage packet-level permissions or app-level prioritization, not per-device bandwidth or VLAN segmentation. Creating a new WLAN is unnecessary since RUCKUS policy management allows dynamic device-based enforcement on a single SSID.
