Method 1: SLAAC

Which dynamic addressing method for GUAs is the one where devices rely solely on the contents of the RA message for their addressing information?

Method 3: Stateful DHCPv6

Which dynamic addressing method for a GUAs is the one where devices rely solely on a DHCPv6 server for their addressing information?

False

True or False: The Subnet ID field in a GUA must borrow bits from the interface ID.

True

True or False? IPv6 was designed with subnetting in mind.

EUI-64 randomly generated

What are the two methods a device can use to generate its own IPv6 interface ID?

a subnet ID that is used to identify networks inside of the local enterprise site an interface ID that is used to identify the local host on the network a global routing prefix that is used to identify the network portion of the address that has been provided by an ISP
