Which of the following is true when describing a link-local address?
Options: Packets addressed to a unicast address are delivered to a single interface., These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4., These are like private addresses in IPv4 in that they are not meant to be routed., These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.

The advantage of a command processor running only built-in commands is:
Options: flexibility to the users in running lists of commands by simply collecting them in named batch command files, the command set being common across different hardware configurations, users can create system programs and run them as commands, the processing is much faster than would other-wise be the case when user defined commands are used
