What is a reason to configure LAG (link aggregation) on a Cisco WLC?

Configuring Link Aggregation (LAG) on a Cisco Wireless LAN Controller (WLC) provides both link redundancy and load balancing. Redundancy is achieved because if one physical link in the LAG bundle fails, traffic automatically shifts to the remaining active links, preventing service interruption. Load balancing distributes traffic across all active links in the bundle, increasing the overall throughput capacity between the WLC and the connected switch. Incorrect options: LAG does not increase security or encrypt management frames; those are functions of security protocols like WPA3 or management frame protection. LAG enables failover between physical links within the same logical bundle, not to different VLANs. VLAN assignment is independent of LAG. Stateful and link-state failover are typically features of high-availability clustering or routing protocols, not directly a function of LAG on a WLC.
