What is the purpose of the command ping ::1?

• It tests the internal configuration of an IPv6 host.

• It tests the broadcast capability of all hosts on the subnet.

• It tests the multicast connectivity to all hosts on the subnet.

• It tests the reachability of the default gateway for the network.

What are the three parts of an IPv6 global unicast address? (Choose three.)

• an interface ID that is used to identify the local network for a particular host

• a global routing prefix that is used to identify the network portion of the address that has been provided by the ISP

• a subnet ID that is used to identify networks inside the local enterprise site
