You have a customer who wants to install Windows XP professional on her computer. What is the
minimum amount of RAM she must have for this to work?

A.
128 Megabytes

B.
64 Megabytes

C.
2 Gigabytes

D.
1 Gigabyte

Explanation:

64 Megabytes is the minimum. Now, this may seem odd as many modern machines come with 1, 2,
or even 4 gigabytes of RAM. Remember, we are asking in this question what the minimum amount
of RAM is. You should absolutely consider getting more RAM.
What are the minimum requirements for installing Windows XP Professional?
The minimum requirements for installing Windows XP Professional are:
Processor: Pentium II processor running at 233MHz or faster.
RAM: 64MB minimum. Microsoft recommends 128MB RAM.
Hard Disk Drive: 1.5GB of free hard disk space for boot partition. More space will be needed if
installing over a network.
Video Card and Monitor: Running at VGA resolution or higher. Network Card: PXE-enabled or a
network boot disk and network card for network-based installation. Other Appliances: CD-ROM or
DVD drive for CD-ROM-based and DVD-based installations, Keyboard and pointing device.
Answer options D, A, and C are all incorrect. Obviously more RAM is always a good idea, but these
numbers are not the minimum requirements.
