Refer to the exhibit. Which two statements are true?（）
A. DHCPDISCOVER packets will reach the DHCP server.
B. The router will not forward DHCPDIS COVER packets because it has not been configured to do so.
C. This configuration is applied to interface Fa0/1.
D. DHCPDISCOVER packets will not reach the DHCP server because DHCPDISCOVER packets are broadcasts.
