For the A+ exam, however, it's important to know that Last Known Good Configuration should be used if a device driver or something in the Registry becomes corrupted and keeps you from booting into the OS, whereas Recovery Console would be used to fix a damaged MBR or boot sector (using fixmbr or fixboot).
