Load Balancing can be configured to balance clients across access points based on which two criteria?
(Choose two.)

• A. Client device type
• B. Proximity
• C. Client RSSI
• D. AP capacity
• E. Client count

正解：C、E

解説：
Client Load Balancingin RUCKUS WLANs is designed to optimize client distribution among nearby access points, preventing over-association to a single AP and improving overall airtime efficiency.
According to theRUCKUS One Online Help - Load Balancing and Band SteeringandRUCKUS Analytics 3.5 User Guide - Client Distribution Analysis, SmartZone load balancing can be configured using two key parameters:
* Client RSSI (B):The system evaluates the signal strength of a client device relative to multiple APs to ensure that it connects to the most suitable AP, not necessarily the strongest or first one detected.
* Client Count (C):Balances client connections by redistributing associations when one AP exceeds a configured threshold compared to its neighbors.
AP capacityanddevice typeare not direct load-balancing criteria, andproximityis implicitly derived from RSSI measurements rather than configured explicitly.
Therefore, the correct answers areB (Client RSSI)andC (Client count).

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

• A. Create a new WLAN for ChromeOS with a rate-limited VLAN.
• B. Create an Application Control Policy and apply it to the WLAN.
• C. Create a Layer 2 Access Control Policy and apply it to the WLAN.
• D. Create a Device Policy and apply it to the WLAN.

正解：D

解説：
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.

Which factor primarily determines the maximum theoretical throughput of a Wi-Fi link?

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

正解：D

解説：
The maximum theoretical throughput of a Wi-Fi link is primarily defined by the channel width (e.g., 20, 40, 80, or 160 MHz) and the Modulation and Coding Scheme (MCS) rate selected by the device.
As stated in the RUCKUS 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 sufficient SNR, which influences the MCS level that can be sustained.
