B) 2.4GHz
C) 1.8GHz
D) 5GHz

3. 关于瘦 AP 数据转发的方式和逻辑,下列说法正确的是:

A) 如果直接在 AP 上手动配置 AC 的 IP 地址,也可以完成三层注册但由于这种方式需要做初始化配置,实施比较麻烦,所以并不推荐。
B) DNS 方式下,只需要在 DNS sever 上指定相关的域名映射到 ACIP 地址即可,并不需要 DHCP server 做特殊配置
C) 三层注册 Option 方式下, AP 获取到 IP 地址后会直接向 Opt on 指定的 AC 地址发送 Discovery 单播发现请求报文
D) 三层注册 Option 方式下, AP 获取 IP 地址后会先发送广播型 Discovery 报文,未收到 AC 相应时,才会开始尝试发送单播发现请求报文。
