NEW QUESTION # 14
When configuring a WLAN for 802.1X, which mode will provide authentication service for APs in the event of a controller failure?

• A. Proxy
• B. Local user database
• C. Dynamic PSK
• D. Non-proxy

Answer: B

Explanation:
When configuring an 802.1X-secured WLAN, RUCKUS systems such as SmartZone, RUCKUS One, or RUCKUS Cloud typically rely on an external RADIUS server for user authentication. However, in the event of a controller failure or connectivity loss to the RADIUS server, RUCKUS APs can continue to authenticate users locally if the local user database is enabled and configured.
The Local Authentication Database allows APs or controllers to store a limited set of credentials that can be used when external AAA services are unavailable. This ensures continued access and redundancy for critical WLANs without requiring external dependency. According to RUCKUS One Online Help - WLAN Configuration and AAA Settings, enabling the Local Authentication Database provides fallback authentication for 802.1X clients during system or connectivity failures.
In contrast, the proxy and non-proxy modes define how authentication requests are relayed to the RADIUS server, while Dynamic PSK (DPSK) is a separate authentication method that replaces 802.1X with per-user keys.

NEW QUESTION # 15
Which two 802.1X Roles are available when 802.1X is enabled on an Access Port in an Ethernet Port Profile? (Choose two.)

• A. MAC-based Authenticator
• B. Port-based Authenticator
• C. Authentication Server
• D. Supplicant
• E. Host-based Authenticator

Answer: B,D

Explanation:
When enabling 802.1X authentication on a RUCKUS Access Port via an Ethernet Port Profile (used for ICX switches or AP wired interfaces), the available roles are:
(A) Supplicant: The device (AP or switch port) acts as the client that must authenticate to the upstream authenticator (e.g., a switch or NAC system).
(C) Port-based Authenticator: The device enforces 802.1X authentication for devices connected to it (e.g., a switch controlling a connected host).
According to RUCKUS One Online Help - 802.1X and Wired Authentication Configuration and RUCKUS Analytics 3.5 User Guide - Wired Client Authentication Monitoring, these two roles define whether the port initiates or enforces authentication.
"Host-based" and "MAC-based" refer to specific authentication methods, not roles, and "Authentication Server" (e.g., RADIUS) is an external entity, not a port role.

NEW QUESTION # 16
Which two are true of a SmartZone cluster backup? (Choose two.)

• A. It can be restored onto a cluster of any SmartZone model.
• B. It can be performed even if the system services are stopped.
• C. It is much smaller than a configuration backup.
• D. It puts the controller into maintenance mode when executed.
• E. It contains IP addressing and client statistical information.

Answer: D,E

Explanation:
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).

NEW QUESTION # 17
Which three actions help keep airtime utilization low within a wireless deployment? (Choose three.)

• A. Requiring all APs to use full transmit power
• B. Placing APs for coverage only
• C. Ensuring sufficient AP capacity for clients
• D. Creating extra WLANs to spread usage
• E. Mitigating sources of non-802.11 interference
• F. Limiting older/legacy clients

Answer: C,E,F

Explanation:
Maintaining low airtime utilization is key to achieving high efficiency and performance in Wi-Fi networks. RUCKUS recommends minimizing factors that increase channel contention and protocol overhead.
Per RUCKUS One Online Help - Airtime Management and Optimization and RUCKUS AI Documentation - Channel Utilization Insights, the following actions are most effective:
(A) Limiting older/legacy clients: 802.11a/b/g clients transmit at lower rates and occupy more airtime per packet.
(D) Ensuring sufficient AP capacity for clients: Proper AP density ensures users are distributed evenly, reducing per-AP contention.
(F) Mitigating non-802.11 interference: Removing microwave ovens, Bluetooth devices, and other RF noise sources prevents wasted airtime from retries.
Adding more SSIDs (WLANs) increases management frame overhead, and full transmit power causes excessive cell overlap-both raise airtime use.

NEW QUESTION # 18
Which factor primarily determines the maximum theoretical throughput of a Wi-Fi link?

• A. Transmit power level
• B. Signal-to-noise ratio (SNR)
• C. Channel width and MCS rate
• D. Beacon interval timing

Answer: C

Explanation:
Themaximum theoretical throughputof a Wi-Fi link is primarily defined by thechannel width(e.g., 20, 40,
80, or 160 MHz) and theModulation and Coding Scheme (MCS) rateselected by the device.
As stated in theRUCKUS One Online Help - PHY and Data Rate Concepts, throughput increases with wider channels and higher modulation (e.g., 1024-QAM in Wi-Fi 6). However, achieving these rates depends on sufficientSNR, which influences the MCS level that can be sustained.
RUCKUS Analytics collects PHY rate metrics to validate link efficiency and helps determine whether MCS downgrades are caused by environmental noise or interference.
Transmit power and beacon timing affect stability, not raw throughput.

NEW QUESTION # 19
What unit is commonly used to display RSSI values?

• A. Watts
• B. Ohms
• C. dBi
• D. dBm

Answer: D

Explanation:
RSSI (Received Signal Strength Indicator)is a key measurement representing the power level of a received RF signal. It is typically displayed indBm (decibel-milliwatts), a logarithmic unit that expresses the power relative to 1 milliwatt. In Wi-Fi systems, RSSI values usually range between-30 dBm (excellent)and-90 dBm (very weak).
According to theRUCKUS One Online Helpand theRUCKUS Analytics 3.5 User Guide, signal strength metrics shown in dashboards, client views, and RF reports are represented indBmfor consistency across platforms. This allows network engineers to correlate signal levels with client connectivity performance and thresholds used for roaming or troubleshooting.
Other units such asdBirefer to antenna gain,Wattsmeasure absolute power (not typically used in client reporting), andOhmsmeasure resistance. Thus,dBmis the correct and standard unit used for RSSI measurement in RUCKUS and all IEEE 802.11-based systems.

NEW QUESTION # 20
Which two statements about Auto Cell Sizing (ACS) are true? (Choose two.)

• A. It can automatically adjust radio power.
• B. It can automatically adjust channel selection.
• C. It is enabled by default.
• D. Tx power can be manually adjusted when using Auto Cell Sizing.
• E. It requires background scanning to be enabled.

Answer: A,E

Explanation:
Auto Cell Sizing (ACS)is a RUCKUS feature designed to automatically optimize the RF environment by dynamically adjustingtransmit power levelsof access points to ensure balanced coverage and minimal interference between APs.
According to theRUCKUS One Online Help - RF Management and Auto Cell SizingandRUCKUS AI documentation - RF Optimization Tools, ACS:
* Automatically adjusts radio transmit power (B)based on environmental conditions and neighboring AP coverage.
* Requires background scanning to be enabled (D)so the system can measure the surrounding RF conditions and interference patterns.
ACS doesnot automatically adjust channel selection, as that functionality is handled byChannelFly, a separate RUCKUS technology. It isnot enabled by default, and manual power tuning is typically disabled when ACS is active, since the controller manages power dynamically to maintain optimal cell overlap.
Thus, the correct answers areB(it can automatically adjust radio power) andD(it requires background scanning to be enabled).

NEW QUESTION # 22
When designing for a high-density large public venue (LPV) deployment such as a stadium, which three considerations need to be taken into account? (Choose three.)

• A. Effect of human bodies on RF propagation
• B. Versions of iOS and Android used on mobile devices
• C. WAN connection speed
• D. Expected number of devices
• E. Expected number of VPN connections
• F. Availability of mobile device charging points

Answer: A,B,D

Explanation:
Designing Wi-Fi for Large Public Venues (LPV) such as stadiums, arenas, or convention centers requires a highly strategic RF approach to handle extreme client density and dynamic environmental factors.
According to RUCKUS One Online Help - High-Density Design Best Practices and RUCKUS AI Documentation - LPV Deployment Planning, three critical considerations are:
Expected number of devices (B): Determines AP count, bandwidth capacity, and airtime utilization. LPV environments often exceed one device per seat, requiring precise capacity planning.
Effect of human bodies on RF propagation (D): Human absorption of 2.4 GHz and partial reflection of 5 GHz signals dramatically affects coverage. RUCKUS recommends directional antennas and elevated AP placement to overcome this.
Other factors like WAN speed and charging stations are operational but not primary design variables in LPV RF engineering.

NEW QUESTION # 24
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?

• A. SNMPv3 is not enabled on SmartZone.
• B. SmartZone High Scale is required for ICX switch management.
• C. SmartZone is not configured to allow self-signed certificates.
• D. DHCP options are not properly configured for the switch.

Answer: C

Explanation:
When deployingSmartZone-Essentials (SZ-100/SZ-144)forRUCKUS ICX switch management, the switches establish a secure HTTPS-based connection to the controller using theSmartZone registrar IP. A common issue preventing connection occurs whenSmartZone is not configured to accept self-signed certificates-which are typically used by ICX switches by default for initial onboarding.
As described in theRUCKUS One Online Help - SmartZone Switch Management SetupandRUCKUS AI documentation, administrators must explicitly enable the option to"Allow Self-Signed Certificates"in the controller'sSwitch 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-Essentialsfully supports ICX management;SmartZone High Scaleis not required.
Thus, the correct answer isC- the connection fails because the controller is not set to accept self-signed certificates from the switch.

• A. Rate Limit
• B. URL Filter
• C. Deny
• D. QoS
• E. Local Breakout
• F. VLAN Assignment

Answer: A,C,D

Explanation:
An Application Policy in SmartZone defines actions applied to identified applications or categories of traffic traversing a WLAN. Using Deep Packet Inspection (DPI), RUCKUS APs recognize application types and enforce predefined behaviors.
According to RUCKUS One Online Help - Application Policy Configuration, the supported rule actions include:
(A) QoS: Assigns priority levels to traffic (Voice, Video, Best Effort, Background) for latency and throughput management.
(B) Deny: Blocks specific applications or categories (e.g., streaming or gaming) to preserve network performance.
(D) Rate Limit: Restricts bandwidth available to defined applications, ensuring fair use of airtime and bandwidth resources.
Local Breakout and VLAN Assignment are functions of traffic forwarding and device policy, not application policy. URL filtering is managed under separate content control modules, not part of Application Policies.

NEW QUESTION # 28
Which statement accurately describes the relationship between SNR and data rate in Wi-Fi networks?

• A. SNR only affects transmit power, not throughput.
• B. Lower SNR allows higher modulation rates.
• C. SNR has no effect when using OFDMA.
• D. Higher SNR supports higher modulation rates.

Answer: D

Explanation:
Signal-to-Noise Ratio (SNR) directly influences the modulation and coding scheme (MCS) that can be used between a Wi-Fi client and AP. A higher SNR allows the AP to select higher-order modulations (e.g., 256-QAM or 1024-QAM), which increases throughput efficiency.
According to RUCKUS One Online Help - RF Signal and SNR Concepts, an SNR of around 25 dB or greater is typically required for high-rate modulation such as MCS 9 or above.
RUCKUS Analytics 3.5 User Guide - PHY Metrics confirms that RUCKUS APs continuously adapt MCS levels based on SNR, optimizing link performance dynamically.
Lower SNR conditions force modulation downshifts (e.g., QPSK or BPSK), reducing data rates for reliability.

NEW QUESTION # 29
What is a true statement regarding MIMO in Wi-Fi networks?

• A. It is supported upstream only.
• B. It needs support on the AP only.
• C. It was introduced in 802.11n.
• D. It uses a single transmitter.

Answer: C

Explanation:
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.

NEW QUESTION # 30
By which process does 802.11k assist in client roaming?

• A. Ignoring join requests for weak clients
• B. Forcing clients to disconnect from their associated AP
• C. Providing a list of available neighbor APs
• D. Caching encryption information

Answer: C

Explanation:
TheIEEE 802.11kamendment enhances Wi-Fi client roaming by allowing an AP to share information about nearby access points with connected clients. This process, known as theNeighbor Report, provides alist of available APsthat the client can use to make faster, more informed roaming decisions.
When a client device receives this neighbor list, it canscan fewer channels, reducing latency and improving the handoff experience-especially in enterprise networks managed byRUCKUS One,SmartZone, or RUCKUS Cloud. According toRUCKUS One Online HelpandRUCKUS AI documentation, enabling
802.11k/v/rfeatures together allows forfast and seamless roaming, as 802.11k supplies discovery data,
802.11v assists with steering decisions, and 802.11r enables fast re-authentication.
OptionCis 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.

NEW QUESTION # 31
Which organization certifies wireless devices as interoperable across vendors?

• A. Internet Engineering Task Force (IETF)
• B. International Standards Organization (ISO)
• C. Institute of Electrical and Electronics Engineers (IEEE)
• D. Wi-Fi Alliance

Answer: D

Explanation:
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.
