Which three options can be configured as roaming triggers on a WGB? (Choose three.)
The correct answer is C. RSSI E. packet retries F. minimum data rate. Workgroup Bridges (WGBs) can be configured to initiate roaming based on specific wireless metrics, including Received Signal Strength Indicator (RSSI), the number of packet retries, and the minimum data rate.

Why each option
Workgroup Bridges (WGBs) can be configured to initiate roaming based on specific wireless metrics, including Received Signal Strength Indicator (RSSI), the number of packet retries, and the minimum data rate.
While Signal-to-Noise Ratio (SNR) is a critical metric for wireless quality, it is typically derived or used internally by devices and not directly configurable as a primary roaming trigger on Cisco WGBs.
Co-channel interference affects wireless performance, but it is not a direct, configurable roaming trigger parameter for WGBs; rather, it is a condition that might lead to other triggers like increased packet retries or lower data rates.
RSSI (Received Signal Strength Indicator) is a common metric used to determine signal quality, and a low RSSI value can trigger a WGB to roam to an AP with a stronger signal.
Packet fragmentation refers to breaking larger packets into smaller ones, which can happen due to various reasons but is not a direct configurable roaming trigger for WGBs.
Excessive packet retries indicate poor link quality or interference, prompting the WGB to roam to an AP that provides a more reliable connection.
A minimum data rate can be configured as a threshold; if the current data rate drops below this value, it signals poor performance and triggers the WGB to seek a better association.
