1. A. Enable the IPv4 address family under the router ospfv3 4 process by using the address-family ipv4 unicast command
2. B. Disable IPv6 on the E0/0 interface using the no ipv6 enable command
3. C. Enable the IPv4 address family under the E0/0 interface by using the address-family ipv4 unicast command
4. D. Disable OSPF for IPv4 using the no ospfv3 4 area 0 ipv4 command under the E0/0 interface

Correct Answer: A

Once again, Cisco changed the IOS configuration commands required for OSPFv3 configuration. The new OSPFv3 configuration uses the “ospfv3” keyword instead of the earlier “ipv6 router ospf” routing process command and “ipv6 ospf” interface commands.
The Open Shortest Path First version 3 (OSPFv3) address families feature enables both IPv4 and IPv6 unicast traffic to be supported. With this feature, users may
have two processes per interface, but only one process per address family (AF).
