Which of the following is true when describing a multicast address?

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

Ethernet and Token-Ring are the two most commonly used network architectures in the world. Jim has heard of the different topologies for networks and wants to choose the architecture that will provide him with the most options. Which of the following would that be? Choose the most correct answer.

Neither Token-Ring nor Ethernet is the proper choice. Only ARCnet can be used in all topologies
Token-Ring because it currently can run at both 4Mbps and 16Mbps. This means that it can be used in any topology
Token-Ring, because it uses a MAU
Ethernet, because it can be set up with most topologies and can use multiple transfer speeds
Ethernet, because it is cabled using fiber-optic cable
