The Background Scanning interval is increased to 90 seconds. Which three processes will take longer to update their data? (Choose three.)
Answer(s): B,C,E
Background Scanning in RUCKUS APs allows radios to periodically scan other channels to collect RF environment data while still serving clients. The scan interval determines how often the AP samples channel information for features like ChannelFly, Auto Cell Sizing, and rogue detection.According to RUCKUS One Online Help Background Scanning and RF Management, and RUCKUS Analytics 3.5 User Guide RF Monitoring, increasing the Background Scanning interval to 90 seconds delays updates for processes that depend on real-time RF sampling, specifically:Rogue AP Detection (B): Takes longer to discover unauthorized or neighboring APs.Auto-Channel Selection (C): Updates channel quality metrics less frequently, slowing responsiveness to interference changes.Auto Power Adjustment (E): Depends on scanning results to optimize transmit power for coverage balance, so adjustments occur less frequently.Processes such as client count and throughput measurement rely on active client data, not background scanning, and spectrum analysis operates in a dedicated analysis mode outside of normal scanning intervals.

Which three external proxy and non-proxy authentication services are available in SmartZone? (Choose three.)
Answer(s): A,B,E
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).

Load Balancing can be configured to balance clients across access points based on which two criteria? (Choose two.)
Answer(s): B,C
Client Load Balancing in RUCKUS WLANs is designed to optimize client distribution among nearby access points, preventing over-association to a single AP and improving overall airtime efficiency.According to the RUCKUS One Online Help Load Balancing and Band Steering and RUCKUS Analytics 3.5 User Guide Client Distribution Analysis, SmartZone load balancing can be configured using two key parameters:Client RSSI (B): The system evaluates the signal strength of a client device relative to multiple APs to ensure that it connects to the most suitable AP, not necessarily the strongest or first one detected.Client Count (C): Balances client connections by redistributing associations when one AP exceeds a configured threshold compared to its neighbors.AP capacity and device type are not direct load-balancing criteria, and proximity is implicitly derived from RSSI measurements rather than configured explicitly.Therefore, the correct answers are B (Client RSSI) and C (Client count).

Which two statements are true regarding roaming on RUCKUS WLANs? (Choose two.)
Answer(s): C,D
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).

Which 802.11 PHY layer feature allows Wi-Fi 6 (802.11ax) to efficiently serve multiple clients simultaneously on both uplink and downlink?
Answer(s): B
OFDMA (Orthogonal Frequency Division Multiple Access) is one of the core features introduced in IEEE 802.11ax (Wi-Fi 6). It divides a channel into smaller subcarriers called Resource Units (RUs), allowing an AP to communicate with multiple clients simultaneously, both on uplink and downlink.According to the RUCKUS One Online Help Wi-Fi 6 Features Overview, OFDMA improves spectrum efficiency, reduces latency, and increases throughput in high-density environments. RUCKUS APs such as the R750 and R850 use OFDMA in coordination with RUCKUS AI's client traffic analysis to allocate resources dynamically.In contrast, MU-MIMO also supports multi-user communication but only in one direction (downlink for 802.11ac Wave 2, both for 11ax). QAM256 enhances modulation efficiency but doesn't enable concurrent multi-client service.
