Computer Networking Which of the following is true when describing a global unicast address? These are like private addresses in IPv4 in that they are not meant to be routed. These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4. 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.

Computer Networking What is the main reason the OSI model was created? So Cisco could use the model. So different networks could communicate. To create a layered model larger than the DoD model. So application developers can change only one layer's protocols at a time. So Cisco could use the model. So different networks could communicate. To create a layered model larger than the DoD model.
