• C

• D

Explanation

Option C is correct because Huawei WLAN load balancing allows the switching threshold to be configured in two distinct ways: based on the number of associated users on an AP, or based on traffic volume (bandwidth utilization). This gives administrators flexibility to trigger load balancing using whichever metric best suits their network environment.

Option A is wrong because wireless controllers (ACs) in Huawei's WLAN architecture do not support stacking. High availability for ACs is achieved through mechanisms like hot standby (HSB) or dual-link backup - stacking is a feature that belongs to switches, not controllers.

Option B is wrong because Huawei AP radio frequency calibration is not categorized as "global tuning and local tuning." The actual classification is based on calibration timing modes (such as scheduled and real-time/triggered calibration), not a global-versus-local distinction.

Option D is wrong because the behavior described for dual-link backup in tunnel forwarding mode is inaccurate - in tunnel mode, traffic flows through the AC, and during failover the active AC handles continuity in a way that contradicts whatever the truncated option claims.

Memory tip: For load balancing thresholds, remember "two counters - heads or bytes." You either count the users (heads) or count the traffic (bytes), and Huawei lets you pick which one triggers the switch.
