AnUnleashed backup file(e.g., RUCKUS-Unleashed_db_082719_ll_07.bak) contains a comprehensive snapshot of theUnleashed network configuration, including SSIDs, WLAN policies, AP settings, and network parameters. According to theRUCKUS One Online Help - Backup and Restoresection, administrators can use this file to:
* Restore all configuration settings(A), re-establishing the network's operational state.
* Restore only WLAN settings(B), providing flexibility when preserving SSID configurations while leaving system details unchanged.
* Restore all configuration except the system name and IP address(E), allowing recovery to a new system without IP conflicts.
The backup file cannot display the configuration ascleartext, as it is encrypted for security. It also cannot restoreSmartZonecontroller configurations orICX switch settingsdirectly-those require separate management mechanisms.
Thus, the valid operations areA,B, andE.

The SmartZone Trace Tool enables administrators to capture packet-level traces from selected APs, clients, or controller interfaces to troubleshoot communication issues.
As defined in RUCKUS One Online Help - Trace and Packet Capture, this tool is used to analyze AP-to-controller join problems, authentication failures, or network latency conditions. Administrators specify the client MAC and associated AP(s) to collect targeted trace logs.
RUCKUS Analytics 3.5 User Guide - Client Troubleshooting Section further notes that trace outputs can be downloaded as .pcap files for Wireshark analysis, providing detailed visibility into control-plane and data-plane interactions.
Other options serve different roles: AP Debug Mode provides command-line diagnostics; Network Health Dashboard shows aggregated metrics; Cluster Diagnostics assesses overall cluster health.

MIMO (Multiple Input, Multiple Output) is a fundamental wireless technology that enhances Wi-Fi throughput and reliability by transmitting multiple data streams simultaneously using multiple antennas on both the transmitter and receiver. It was introduced in the IEEE 802.11n standard, which marked the beginning of high-throughput (HT) Wi-Fi.
According to RUCKUS One Online Help and the RUCKUS Analytics 3.5 User Guide, MIMO enables spatial multiplexing, diversity gain, and beamforming, allowing higher data rates and improved signal quality in multipath environments. Subsequent standards (802.11ac and 802.11ax) expanded this concept to MU-MIMO (Multi-User MIMO), allowing simultaneous communication with multiple clients.
MIMO requires support on both the AP and client for full functionality; otherwise, the connection falls back to single-stream operation. It is used in both uplink and downlink directions (especially in Wi-Fi 6 and later). Thus, option B-introduced in 802.11n-is correct, while options A, C, and D are incorrect.

TheWi-Fi Alliance (WFA)is the global organization responsible fortesting and certifying interoperability of wireless LAN products based on the IEEE 802.11 standards. While theIEEEdevelops and maintains the technical specifications (e.g., 802.11a/b/g/n/ac/ax), it doesnotperform certification or compliance testing.
Instead, the Wi-Fi Alliance ensures that certified devices from different manufacturers operate together seamlessly under the"Wi-Fi CERTIFIED™"program.
According toRUCKUS One Online Helpand theRUCKUS AI documentation, RUCKUS access points and controllers undergo Wi-Fi Alliance certification to ensure compatibility with a wide range of client devices, including those using WPA3, Wi-Fi 6 (802.11ax), and Wi-Fi 6E technologies. This certification is critical for enterprise environments where heterogeneous client ecosystems exist.
TheIETFfocuses on internet protocols (e.g., IP, TCP), and theISOhandles broader international standards, not wireless interoperability. Therefore, theWi-Fi Allianceis the correct organization ensuring cross-vendor interoperability for Wi-Fi.

Cloud Auto-Upgrade is a RUCKUS One feature that automatically updates AP firmware to the latest stable release without requiring manual scheduling.
According to RUCKUS One Online Help - Firmware and Lifecycle Automation, this capability ensures security compliance and performance optimization across managed APs. Administrators can opt in or out of automatic updates per site or organization.
SmartZone uses manual scheduling via Image Management, while RUCKUS One provides hands-free upgrades integrated into its cloud management platform.
