NEW QUESTION # 62
What unit is commonly used to display RSSI values?
Answer: C
Explanation:
RSSI (Received Signal Strength Indicator) is a key measurement representing the power level of a received RF signal. It is typically displayed in dBm (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 the RUCKUS One Online Help and the RUCKUS Analytics 3.5 User Guide, signal strength metrics shown in dashboards, client views, and RF reports are represented in dBm for 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 as dBi refer to antenna gain, Watts measure absolute power (not typically used in client reporting), and Ohms measure resistance. Thus, dBm is the correct and standard unit used for RSSI measurement in RUCKUS and all IEEE 802.11-based systems.

NEW QUESTION # 63
By which process does 802.11k assist in client roaming?
Answer: D
Explanation:
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.

NEW QUESTION # 64
Which statement accurately describes the relationship between SNR and data rate in Wi-Fi networks?
Answer: B
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 # 65
The Background Scanning interval is increased to 90 seconds. Which three processes will take longer to update their data? (Choose three.)
Answer: B,C,F
Explanation:
Background Scanning in RUCKUS APs allows radios to periodically scan other channels to collect RF environment data while still serving clients. The scan interval determines how often the AP samples channel information for features like ChannelFly, Auto Cell Sizing, and rogue detection.
According to RUCKUS One Online Help - Background Scanning and RF Management, and RUCKUS Analytics 3.5 User Guide - RF Monitoring, increasing the Background Scanning interval to 90 seconds delays updates for processes that depend on real-time RF sampling, specifically:
Rogue AP Detection (B): Takes longer to discover unauthorized or neighboring APs.
Auto-Channel Selection (C): Updates channel quality metrics less frequently, slowing responsiveness to interference changes.
Auto Power Adjustment (E): Depends on scanning results to optimize transmit power for coverage balance, so adjustments occur less frequently.
Processes such as client count and throughput measurement rely on active client data, not background scanning, and spectrum analysis operates in a dedicated analysis mode outside of normal scanning intervals.

NEW QUESTION # 66
Review the output. Which two states can be determined from this output? (Choose two.) rkscli: get scg
----- SCG Information ------
SCG Service is enabled.
AP is managed by SCG.
State: RUN_STATE
Server List: 10.1.1.245,47.187.140.218
SSH tunnel connected to 10.1.1.245
Failover List: Not Found
Failover Max Retry: 2
DHCP Opt43 Code: 6
Server List from DHCP (Opt43/Opt52): Not found
SCG default URL: RuckusController
SCG config heartbeat intervals: 30 | 30
SCG gwloss|serverloss timeouts: 1800 | 86400
Controller Cert Validation: disable
OK
Answer: B,D
Explanation:
The SmartZone CLI command get scg provides detailed information about an AP's connection to its controller.
From the output provided:
* The "State: RUN_STATE" line confirms the AP is fully connected, accepted, and managed by the controller ( E ). If the AP were pending, it would display "JOIN_STATE" or "CFG_STATE."
* The presence of two controller IPs and an SSH tunnel connection to 10.1.1.245 indicates a control- plane tunnel established via NAT traversal, meaning the controller is behind a control NAT IP ( D ).
The "Controller Cert Validation: disable" line shows certificate validation is off, but it doesn't affect operational state. The Server List confirms static IP discovery rather than DNS-based assignment.
Thus, the AP is active and managed by the controller, with communication handled through an SSH-based control tunnel.
