Refer to the exhibit. What will be the result of entering the commands as shown in the exhibit?

RIPng will not be enabled on interface fa0/0 because the network address is a broadcast address.

RIPng will not be enabled on this interface because the IPv6 address is only /64 bits long.

RIPng will be enabled on interface fa0/0 and will advertise the configured network.

The IPv6 interface configuration requires a network statement for the network.

The IPv6 routing instance must be called RTA not RT0.
