Why each option
A wireless controller provides Radio Resource Management (RRM) services to manage interference and optimize performance in dense wireless networks.
Mitigating threats from the internet is primarily a function of firewalls, intrusion detection/prevention systems (IDS/IPS), or other security appliances, not a wireless controller's main role.
Wireless LAN Controllers (WLCs) offer Radio Resource Management (RRM) capabilities that automatically optimize wireless network performance by adjusting AP power levels, channels, and load balancing, effectively managing interference in dense environments.
While some WLCs can provide basic inter-VLAN routing for wireless clients, Layer 3 routing between wired and wireless devices is typically handled by dedicated routers, not the primary service of a WLC.
Issuing IP addresses (DHCP) can be a feature on some WLCs, but it is not their unique or primary service; DHCP is often handled by dedicated DHCP servers or routers for both wired and wireless devices.
