You need to manually assign IPv6 addresses to the interfaces on an IPv6-enabled router. While assigning addresses, you need to ensure that the addresses
participate in neighbor discovery and in stateless auto-configuration process on a physical link.
Which of the following addresses can be assigned to the interfaces?
A.
FEC0:0:0:1::1/64
B.
FE80::260:3EFF:FE11:6770/10
C.
2001:0410:0:1:0:0:0:1/64
D.
2002:500E:2301:1:20D:BDFF:FE99:F559/64
Explanation:
The FE80::260:3EFF:FE11:6770/10 address can be assigned to an interface of the IPv6-enabled router. This address is a link-local address as it has the prefix
FE80::/10. Link-local addresses can be configured for an interface either automatically or manually.
Link-local addresses are IPv6 unicast addresses that are configured on the interfaces of an IPv6-enabled router. With link-local addresses, the nodes can connect
to a network (local link) and communicate with other nodes. In addition, these addresses participate in the neighbor discovery protocol and the stateless autoconfiguration process.
The FEC0:0:0:1::1/64 address should not be used for the interfaces because this address is a site-local address. Site-local addresses are IPv6 equivalent
addresses to IPv4’s private address classes. These addresses are available only within a site or an intranet, which typically is made of several network links.
You should not use the 2001:0410:0:1:0:0:0:1/64 and 2002:500E:2301:1:20D:BDFF:FE99:F559 addresses for the interfaces. These two addresses are global
unicast addresses as they fall in the range from 2000::/3 and to E000::/3. A global address is used on links that connect organizations to the Internet service
providers (ISPs).
