Which of the following is true when describing an anycast address?

Packets are delivered to all interfaces identified by the address. This is also called one-to-many addresses.
Packets addressed to a unicast address are delivered to a single interface.
This address identifies multiple interfaces and the anycast packet is only delivered to one address. This address can also be called one-to-one-of-many.
These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.

The difference between a multiplexer and a statistical multiplexer is

Statistical multiplexers need buffers while multiplexers do not need buffers
Multiplexer use X.25 protocol, while statistical multiplexers use the Aloha protocol
Multiplexers use Time Division Multiplexing (TDM) while statistical multiplexers use Frequency Division Multiplexing (FDM)
None of these
Multiplexers often waste the output link capacity while statistical multiplexers optimize its use
