题库的答案是C,D

Reference: https://www.cisco.com/c/en/us/support/docs/wireless/5500-series-wireless-controllers/119286-lap-notjoin-wlc-tshoot.html#backinfo
下面这句话：
if you do not tell the LAP where the controller is via DHCP option 43, DNS resolution of "Cisco-capwap-controller.local_domain", or statically configure it, the LAP does not know where in the network to find the management interface of the controller.

答案是：

C. DHCP Option 43

D. broadcasting on the localsubnet

官方寫的是：cisco-capwap-controller

答案選項是：CISCO-DNA-PRIMARY.localdomain

沒發現你標的黃色重點跟答案選項不一樣嗎？

一般用DHCPoption43， https://www.cisco.com/c/en/us/su ... p-option-43-00.html, 其次是local broadcast 255.255.255.255，最后用DNS
