DHCP snooping is enabled on Switch A.Detailed requirements are as follows:z Client A (with the MAC address of 00-01-02-03-04-06) obtains an IP address through the DHCPserver.z On Switch A, create a DHCP snooping entry for Client A.z On port GigabitEthernet 1/0/1 of Switch A, enable dynamic binding function to prevent attackersfrom using forged IP addresses to attack the server.
