Which command will be used to display file and directory names only, without size, date, and time information?
Answer: C
Correct answer: DIR/B
The /B (bare) switch lists names alone, with no heading, no size, date or time, and no summary line - which is what makes it useful for piping into another command or capturing to a file. /W gives a wide listing and /S descends into subdirectories.

The _____ command allows you to modify the default prompt to provide other information
Answer: A
Correct answer: prompt
The PROMPT command redefines what DOS displays before each command. Its codes stand for pieces of information - $p for the current path, $g for the greater-than sign, $t for the time - so PROMPT $P$G gives the familiar C:\DOS>.

Which of the following commands will take you directly to the root directory no matter what subdirectory you are currently in?
Answer: B
Correct answer: CD\
CD\ changes to the root of the current drive from wherever you are, because the leading backslash makes the path absolute. CD.. only moves up one level, so from a deep subdirectory it takes several goes.

After trying to unload a TSR, you get an error message saying that other TSRs were loaded after the one you tried to remove. Which of the following commands could you use to see the current load order?

Which command is used to send the contents of file named REPORT.TXT to the standard printing device?
Answer: B
Correct answer: TYPE REPORT.TXT > PRN
> redirects standard output, and PRN is the DOS device name for the standard printer, so TYPE REPORT.TXT > PRN sends the file’s contents there instead of to the screen. The pipe symbol feeds output into another program, and PRN is a device, not a program.

Answer: D
Correct answer: Extended Memory
HIMEM.SYS is the extended memory manager: it takes charge of the memory above 1 MB and hands it out through the XMS interface, which is why it must be loaded before EMM386, SMARTDRV or DOS=HIGH can do anything.
