- Da global routing prefix that is used to identify the portion of the network address provided by a local administrator
- Ean interface ID that is used to identify the local host on the network
14An administrator wants to configure hosts to automatically assign IPv6 addresses to themselves by the use of Router Advertisement messages, but also to obtain the DNS server address from a DHCPv6 server. Which address assignment method should be configured?

- Dthe destination device is reachable through the network
- Ethe average time it takes each router in the path between source and destination to respond
17What is the purpose of ICMP messages?
- Ato inform routers about network topology changes
- Bto ensure the delivery of an IP packet
