Hi All! I can't figure out this one...Sad

Q: You are the desktop administrator for your company. All users in the network have Windows XP Professional computers. Users in the research department  have dual-processor computers.
Users in the research department report that when they run 16-bit Windows programs, their computer performance becomes very slow. You use system  monitor to monitor the users‘«÷ computers. You discover that when the users are running their 16-bit applications, one processor shows a sustained utilization of  more than 90 percent while the other processor only shows utilization of less than 10 percent.

You need to improve application performance for the users in the research department.
What should you do?

A. Configure each application to run in a separate memory space.
B. Configure each application to run in AboveNormal priority class.
C. For each application, set the compatibility mode to Windows 95.
D. Configure processor affinity for each application to allow it to run on both processors.

I would say A. Running in separate memory space means running in different NTVDMs -- NT Virtual Dos Machine.

An NTVDM is a win32 process, therefore if you start 2 of them, they will be load-balanced over your two CPUs.

If you start both apps in the same NTVDM, only one CPU will get the gig... makes sense?

Did you read 70-270 for freaks! today? Wink

awesome! Congrats Smiley

You chose the right answer as well! Start /separate is the command line way to start an app in a separate memory space.

Anybody knows what the other way is?

There is a registry hack that adds a "check-box" option to "run in a separate memory space"  when you click Start & then Run!:D
