Partner Domains are specific to the Virtual SmartZone – High Scale (vSZ-H) management platform. This feature is designed to provide multi-tenancy support for managed service providers (MSPs) and large enterprises managing multiple organizations under a single SmartZone instance.

As defined in the RUCKUS 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.

The vSZ-E (Essentials) version does not support Partner Domains because it is intended for single-tenant environments. Unleashed and RUCKUS Cloud provide simpler management for smaller deployments and inherently separate tenants by account, not by Partner Domain.

Therefore, B (vSZ-H) is the correct answer.

In SmartZone , Generic Routing Encapsulation (GRE) tunnels are used to encapsulate client traffic and forward it to a remote gateway, typically for security or centralized routing.

As described in RUCKUS One Online Help – GRE Tunneling Configuration , a tunnel profile becomes available for WLAN association only when it is explicitly linked to an AP Zone . This ensures that all APs in the zone can apply the correct tunnel endpoint and keying parameters.

If a GRE profile is not mapped to a zone, it will not appear in the WLAN configuration dropdown , even if successfully created.

Other options are incorrect because SmartZone supports GRE for WLANs by design, split-tunnel profiles are optional, and tunnel count limitations are far higher than typical enterprise use.

A SmartZone cluster backup is a comprehensive backup of the controller cluster’s system and configuration data, intended for disaster recovery or migration to similar SmartZone platforms. According to the RUCKUS One Online Help – Cluster Backup and Restore and SmartZone 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 mode to ensure database consistency and prevent configuration changes during the process. This temporarily suspends management operations but preserves data integrity.

Cluster backups cannot be restored to different SmartZone models (e.g., vSZ to SZ-100) due to hardware and licensing differences. Backups also require system services to be active during execution.

Therefore, the correct answers are B (contains IP addressing and client statistical information) and D (puts the controller into maintenance mode when executed).
