Given a network scenario, which step should you perform first when configuring a DHCP server for IPv4?

• Assign DNS server addresses

• Define the IP address pool and subnet mask

• Set up time synchronization

• Configure static routes

When setting up a DHCP server for IPv6, which configuration step is necessary to enable automatic address assignment?
