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

• 1
  Packets addressed to a multicast address are delivered to a single interface
• 2
  packets are delivered to all interfaces identified with the address. This is also called a one-to-many address
• 3
  A multicast address identifies multiple interfaces and is delivered to only one address. This address can also be called one-to-one-of-many
• 4
  These addresses are meant for nonrouting purposes,but they are almost globally unique, so it is unlikely they will have an address overlap
