Which of the following IPv6 address types is a single address that can be assigned to multiple
interfaces?

A.
Unicast

B.
Multicast

C.
Loopback

D.
Anycast

Explanation:

An IPv6 anycast address is a single address that can be assigned to multiple interfaces. For example,
an IPv6 address is assigned to a multi-homed computer. A packet sent to an anycast address is
delivered to the first available interface of a device. An anycast address is used to provide loadbalancing and automatic failover. Currently, anycast addresses are used only as destination
addresses and can be assigned only to routers.
Answer option A is incorrect. A unicast address identifies a single interface within the scope of the
type of unicast address.
Answer option B is incorrect. A multicast address identifies multiple interfaces.
Answer option C is incorrect. The loopback address is used to test your network interface.
