Which three states are indicated by the LEDs on RUCKUS indoor APs? (Choose three.)
A, C, D
Explanation:
RUCKUS indoor Access Points use status LEDs to communicate key operational states during
deployment and runtime. The LEDs provide immediate visual feedback about the AP’s connectivity,
power condition, and client activity.
According to the RUCKUS One Online Help – Access Point LED Indicators, and verified in the RUCKUS
AI documentation, the LEDs typically display the following primary states:
Controller Connected (A): Confirms that the AP has successfully registered and established a control
session with the RUCKUS controller or RUCKUS Cloud instance.
Insufficient PoE Power (C): Indicates that the AP is receiving inadequate power, such as being
powered through 802.3af instead of 802.3at, which may disable high-power features or additional
radios.
Clients Connected to a Radio (D): Lights up when one or more clients are associated with the AP’s
wireless radios, signifying active WLAN operation.
Other listed options—USB dongle inserted, data plane tunnel connected, and routable IP assigned—
are not standard LED indications across RUCKUS indoor AP models. They may represent system
events but not physical LED states.

Which SmartZone controller interface is present only in the physical hardware appliance?
A
Explanation:
The Data Interface is unique to physical SmartZone (SZ) hardware appliances such as the SmartZone
100 (SZ-100) or SmartZone 300 (SZ-300). This interface handles user traffic data forwarding in
hardware-based deployments and is not present in virtualized versions such as the vSZ (Virtual
SmartZone).
According to the RUCKUS One Online Help and SmartZone system architecture descriptions, the
physical controller includes four main interfaces:
Management Interface: Handles GUI, CLI, and administrative access.
Control Interface: Manages control-plane communications with access points.
Cluster Interface: Manages synchronization and redundancy between cluster members.
Data Interface: Dedicated for data-plane traffic processing and forwarding (exclusive to physical
appliances).
Virtual SmartZone controllers use tunnel-based data forwarding (via GRE or VXLAN) instead of a
dedicated hardware Data Interface. Hence, the Data interface exists only on physical appliances,
making A the correct answer.

Which type of interference occurs when two APs are configured on channel 7 and channel 8 in the
same physical space?
A
Explanation:
When two access points operate on overlapping channels in the same frequency band—such as
channel 7 and channel 8 in the 2.4 GHz range—they create Adjacent Channel Interference (ACI).
Unlike co-channel interference (CCI), which occurs when APs share the exact same channel, ACI
results from partial channel overlap that causes energy spillover between adjacent frequencies.
According to RUCKUS One Online Help – Radio Configuration and Channel Planning, adjacent
channels in 2.4 GHz are only 5 MHz apart, while each Wi-Fi channel occupies 20–22 MHz of
bandwidth. As a result, channels like 7 and 8 significantly overlap, creating degraded performance,
retransmissions, and reduced throughput.
RUCKUS’s ChannelFly technology in both RUCKUS AI and RUCKUS Analytics helps automatically
select non-overlapping channels (such as 1, 6, and 11) to minimize ACI and optimize network
capacity.
Therefore, the correct answer is A – Adjacent interference, which directly applies to overlapping
channel configurations.

What happens when enabling spectrum analysis mode on a RUCKUS AP?
A
Explanation:
When spectrum analysis mode is enabled on a RUCKUS Access Point, the AP’s radios are temporarily
dedicated to spectrum scanning and interference analysis, meaning they cannot serve wireless
clients during that period. Therefore, new clients will not be able to join, and existing clients are
typically disconnected.
According to the RUCKUS One Online Help – Spectrum Analysis Tool and RUCKUS AI Documentation
– RF Monitoring and Optimization, spectrum analysis mode captures and reports RF energy
utilization, identifying interference sources such as non-Wi-Fi devices, microwave ovens, or
Bluetooth. The AP alternates its radio into “sniffer” mode to analyze RF characteristics, during which
client association and data traffic handling are suspended.
The output is visualized through graphs and real-time utilization charts, not histograms.
Furthermore, an AP can only scan one band (either 2.4 GHz or 5 GHz) at a time — not both
simultaneously.
Thus, the correct answer is A, since enabling spectrum analysis prevents new client associations
while the AP is in scanning mode.

An administrator has completed a new install of SmartZone-Essentials for switch management, and
has configured the SmartZone IP as the registrar IP on an ICX 7450. Which condition explains why the
switch is not connecting?
C
Explanation:
When deploying SmartZone-Essentials (SZ-100/SZ-144) for RUCKUS ICX switch management, the
switches establish a secure HTTPS-based connection to the controller using the SmartZone registrar
IP. A common issue preventing connection occurs when SmartZone is not configured to accept self-
signed certificates—which are typically used by ICX switches by default for initial onboarding.
As described in the RUCKUS One Online Help – SmartZone Switch Management Setup and RUCKUS
AI documentation, administrators must explicitly enable the option to “Allow Self-Signed
Certificates” in the controller’s Switch Management settings. Without this configuration, the
SmartZone rejects the ICX connection request during SSL/TLS handshake, causing registration failure.
SNMPv3 configuration and DHCP options are unrelated to initial controller registration. Additionally,
SmartZone-Essentials fully supports ICX management; SmartZone High Scale is not required.
Thus, the correct answer is C — the connection fails because the controller is not set to accept self-
signed certificates from the switch.

Which task will throttle download speeds on all ChromeOS devices on the STUDENT SSID and
segment their device traffic into a separate VLAN?
A
Explanation:
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.

A wireless administrator wishes to consolidate the management of RUCKUS APs by onboarding three
new sites to SmartZone 5.2. The APs currently managed by this SmartZone cluster are running AP
firmware 5.2.1.0.1038. The administrator has noted the following AP software versions for each of
the sites:
The APs in San Mateo are running 200.7.10.202.121
The APs in Toronto are running 102.0.0.0.5
The APs in Mexico City are running 5.2.0.0.1412
Which three statements are true with regard to onboarding, one for each of these three sites?
(Choose three.)
D, E, F
Explanation:
In this SmartZone 5.2 onboarding scenario:
San Mateo (200.7.10.202.121): These APs are running Unleashed firmware, which cannot directly
join a SmartZone controller. According to the RUCKUS One Online Help – AP Firmware Migration,
Unleashed APs must first be converted to Standalone (Solo) mode using CLI (set director ip <SZ_IP>
or set scg ip) before they can connect. Thus, D (San Mateo devices can use ap-mode commands to
onboard) is correct.
Toronto (102.0.0.0.5): This firmware version represents ZoneDirector (ZD) code. APs on ZD firmware
communicate using LWAPP, and to migrate them, administrators must perform a firmware
conversion process (using set scg ip) for SmartZone compatibility. Therefore, E (Toronto devices will
use LWAPP to communicate to SmartZone) is correct.
Mexico City (5.2.0.0.1412): These APs already match the SmartZone firmware family (5.2.x), meaning
they are currently or can immediately be managed by this SmartZone cluster. Therefore, F is correct.

Partner Domains are specific to which RUCKUS management platform?
B
Explanation:
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.

Which tool verifies RF spectrum for valid Wi-Fi networks and sources of non-Wi-Fi interference?
D
Explanation:
Chanalyzer is a specialized RF spectrum analysis tool developed for use with Wi-Spy spectrum
analyzers. It is used to visualize and validate Wi-Fi and non-Wi-Fi interference sources across the 2.4
GHz and 5 GHz bands.
According to the RUCKUS One Online Help – Spectrum Analysis and RF Interference Tools, spectrum
analysis tools like Chanalyzer can detect non-802.11 interference sources such as microwave ovens,
Bluetooth devices, DECT phones, and radar signals. While RUCKUS APs have built-in spectrum
analysis mode, Chanalyzer provides external, high-resolution spectrum visualization that helps
confirm interference sources in physical environments.
In contrast, RUCKUS Wi-Fi Planner (or Wi-R Planner) is used for predictive RF design and coverage
estimation, not live interference detection. The WLAN discovery tool identifies SSIDs and basic
network parameters but cannot detect non-Wi-Fi signals.
Therefore, the correct answer is D (Chanalyzer) — the standard tool for verifying valid Wi-Fi
operation and identifying non-Wi-Fi interference sources.

A network administrator has saved a backup file using the default file name “RUCKUS-
Unleashed_db_082719_ll_07.bak”. Which three actions can be taken with this backup file? (Choose
three.)
A, B, E
Explanation:
An Unleashed backup file (e.g., RUCKUS-Unleashed_db_082719_ll_07.bak) contains a
comprehensive snapshot of the Unleashed network configuration, including SSIDs, WLAN policies,
AP settings, and network parameters. According to the RUCKUS One Online Help – Backup and
Restore section, 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 as cleartext, as it is encrypted for security. It also
cannot restore SmartZone controller configurations or ICX switch settings directly—those require
separate management mechanisms.
Thus, the valid operations are A, B, and E.
