You are reviewing disk management basics with a new technician in your department and are currently discussing dynamic disks. Of the following, what do you say is true about dynamic disks?

A. Dynamic disk space is allocated in partitions.

B. The number of volumes in a dynamic disk is limited to four.

C. A volume can extend to include the available space on any hard disk on the computer.

D. Dynamic disk usage began in Windows XP.

Solution

A. The power-on self-test, or POST, is the very first step that occurs when a computer starts: a diagnostic testing sequence that a computer’s basic input/output system runs to determine if the computer keyboard, random access memory, disk drives, and other hardware are working correctly. The POST occurs in all computers and is not specific to Windows, since at this point, the operating system has not yet loaded.
