Câu 82: 300-425: Designing Cisco Enterprise Wireless Networks (300-425 ENWLSD)

Two Cisco 5520 Wireless LAN Controllers are managing all APs throughout the network. The WLCs are in different locations to provide geographical redundancy. A mobility group has been configured on both WLCs and has an UP status on both controllers. The APs in location A are statically configured to use controller A as the primary and controller B as the secondary. If the WLC in location A goes offline, the APs successfully join the WLC in location B, but they do not fail over to the primary configured controller. Which configuration task fixes this issue?
