Partner Domainsare specific to theVirtual SmartZone - High Scale (vSZ-H)management platform. This feature is designed to providemulti-tenancysupport for managed service providers (MSPs) and large enterprises managing multiple organizations under a single SmartZone instance.
As defined in theRUCKUS One Online Help - SmartZone Multi-Tenant Management, Partner Domains allow administrators to create separate logical domains, each with its own system administrators, policies, and reporting. This enables service providers to host multiple customers securely on the same vSZ-H infrastructure without sharing configuration or visibility across domains.
ThevSZ-E (Essentials)version does not support Partner Domains because it is intended for single-tenant environments.UnleashedandRUCKUS Cloudprovide simpler management for smaller deployments and inherently separate tenants by account, not by Partner Domain.
Therefore,B (vSZ-H)is the correct answer.

Indoor WLAN coverage is influenced by multiple RF and physical parameters that determine how effectively a signal propagates and maintains connectivity quality.
According to RUCKUS One Online Help - RF Design Fundamentals and RUCKUS AI Documentation - Coverage Optimization, the three most impactful factors are:
AP Transmit Power (A): Directly affects signal reach; excessive power can cause co-channel interference, while low power results in coverage holes.
AP Orientation (C): Affects signal radiation direction-wall-mounted, ceiling-mounted, or tilted deployments impact pattern uniformity and coverage overlap.
Antenna Pattern (D): Defines gain and directional behavior; omnidirectional antennas provide uniform coverage, while directional models concentrate energy for targeted areas.
Antenna diversity and spatial multiplexing improve throughput and reliability, but do not primarily determine raw coverage boundaries. "Earth bulge" is irrelevant for indoor deployments.

The IEEE 802.11k amendment enhances Wi-Fi client roaming by allowing an AP to share information about nearby access points with connected clients. This process, known as the Neighbor Report, provides a list of available APs that the client can use to make faster, more informed roaming decisions.
When a client device receives this neighbor list, it can scan fewer channels, reducing latency and improving the handoff experience-especially in enterprise networks managed by RUCKUS One, SmartZone, or RUCKUS Cloud. According to RUCKUS One Online Help and RUCKUS AI documentation, enabling 802.11k/v/r features together allows for fast and seamless roaming, as 802.11k supplies discovery data, 802.11v assists with steering decisions, and 802.11r enables fast re-authentication.
Option C is correct because 802.11k's core function is to help clients identify the best potential APs to roam to. The other options describe unrelated functions: encryption caching relates to 802.11r, ignoring weak clients is an AP policy function, and forcing disconnections occurs during load balancing or steering-not through 802.11k.

RUCKUS BeamFlex+is an advanced adaptive antenna technology that dynamically selects from thousands of possible antenna patterns to optimize signal quality and performance for each client connection. Unlike Transmit Beamforming (TxBF), which depends on feedback from client devices that must support specific beamforming protocols,BeamFlex+ operates entirely on the access point side.
The key advantage of BeamFlex+ is thatit does not require any client-side support or compatible drivers.
It continuously analyzes signal characteristics and client locations to select the optimal antenna pattern in real time, enhancing both range and throughput without additional client configuration.
According to theRUCKUS One Online HelpandRUCKUS AI documentation, BeamFlex+ combines adaptive antenna pattern selectionwithpolarization diversity (PD-MRC)to improve performance in dynamic environments. In contrast,Tx Beamformingrequires explicit feedback (channel state information) from clients-limiting its effectiveness when clients lack driver or chipset compatibility.
Thus, the correct answer isD, as BeamFlex+ provides all the benefits of adaptive beamforming without the need for client-side dependencies.

The SmartZone Trace Tool is used to capture and analyze packets related to specific client connectivity sessions, helping administrators identify association, authentication, and DHCP issues.
According to RUCKUS One Online Help - Troubleshooting Tools and Packet Capture and RUCKUS Analytics 3.5 User Guide - Client Connectivity Tracing, the following two pieces of information are required to initiate a trace:
Client MAC Address (C): Identifies the exact device on the network to filter relevant packet captures and session details.
Correct AP(s) to select (D): Specifies the access point(s) currently or recently serving that client, ensuring the trace targets the correct radio interface for capturing traffic.
Other details like device name, AP model, or client OS are useful for contextual understanding but not required inputs for running the trace. The trace tool uses these two core identifiers to isolate logs and generate capture data efficiently for troubleshooting connectivity issues.
