Regarding the method and logic of thin AP P data forwarding, which of the following statements are correct? (Multiple choice)
- A. In the three-layer registration Option43 mode, after the AP obtains the IP address, it will directly send a Discovery unicast discovery request message to the AC address specified by Option43
- B. In the option43 mode of layer three registration, the AP will first send a broadcast discovery message after obtaining an IP address, and will try to send a unicast discovery request message when it does not receive the corresponding AC.
- C. In DNS mode, you only need to specify the relevant domain name on the DNS server to map to the AC IP address, and no special configuration by the DHCP server is required.

- C. wlan service-template 1 has been applied to the radio of the AP, you need to cancel the application first and then enter the command "wlanservice-template 1 crypto". If wlan service-template 1 is not applied, directly enter the command "wlan service-template 1" crypto".
- D. You cannot modify the encryption type of the existing wlan service-template 1. You can only delete the original service-template 1, and then create a new service-template 1 through the command "wlan service-template crypto" to modify it to the purpose of the encryption type, but if wlan service-template1 has been applied to the radio of the AP, the relevant application needs to be released first.
