5. What three primary sources can Migration Assistant pull from?

A) A network client uses the subnet mask to determine whether the destination IP address is on the LAN. If the destination IP address isn't on the LAN, it's assumed the destination address is on another network, and the client sends the data to the IP address of the local network router. The network router then sends the data, via a WAN connection, on to another router that it thinks is closer to the destination. This continues across WAN connections from router to router until the data reaches its destination.
B) The OS X Recovery Disk Assistant can create a small OS XB.Recovery disk that lacks the OS X installation assets. An OS X Installation disk, which includes the full OS X installation assets, can be created by using the create install media command line tool found inside the Install OS X Mavericks application.
C) Migration Assistant can migrate information from other OS X systems, Windows systems, and other disks, including Time Machine backups.
D) Time Machine starts with a full copy of the file system to the backup disk. Then it maintains a list of changes to the file system, and every hour copies only the changes to the backup disk. In the backup, it creates a simulation of the full file system using hard links for files that haven't changed.
