ASmartZone cluster backupis a comprehensive backup of the controller cluster's system and configuration data, intended for disaster recovery or migration to similar SmartZone platforms. According to theRUCKUS One Online Help - Cluster Backup and RestoreandSmartZone Administration Guide (v5.2+), a cluster backup includes:
* Cluster and controller configuration, including IP addressing, zones, AP groups, WLANs, and policies.
* Client statistical data and historical analytics, which are also captured for restoration of system monitoring data.
When a cluster backup is initiated,the controller enters maintenance modeto ensure database consistency and prevent configuration changes during the process. This temporarily suspends management operations but preserves data integrity.
Cluster backupscannot be restored to different SmartZone models(e.g., vSZ to SZ-100) due to hardware and licensing differences. Backups alsorequire system services to be activeduring execution.
Therefore, the correct answers areB(contains IP addressing and client statistical information) andD(puts the controller into maintenance mode when executed).

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.

SmartZone controllerssupport a range ofexternal authentication servicesfor bothproxy (via controller)and non-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).

SmartCast is RUCKUS's advanced Quality of Service (QoS) engine that prioritizes latency-sensitive traffic such as voice, video, and real-time collaboration apps.
According to RUCKUS One Online Help - SmartCast Overview and RUCKUS Analytics 3.5 User Guide - QoS Monitoring, SmartCast identifies traffic types using Deep Packet Inspection (DPI) and applies 802.1p/DSCP markings to preserve QoS across wired and wireless segments.
It dynamically manages airtime scheduling and retransmissions to maintain low delay and jitter. Other features-like BeamFlex+ (antenna optimization) or ChannelFly (channel selection)-do not handle traffic prioritization.

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).
