You work as the network administrator at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers on the Domain.com network run Windows Server 2003 and all client computers run Windows XP Professional.
A Domain.com client named Kara Lang has asked you to configuring Windows XP her computer. There are devices on this computer that are not officially supported by XP. You are requesting drivers from multiple sources. It appears that the system is up and running but is quite unstable with the new drivers.
What feature of the Driver Verifier should you use to view the outstanding allocations the driver has at any point in time?

A.
Driver unload checking

B.
Driver load checking

C.
Driver failure checking

D.
Driver leak checking

E.
Pool Leakage Detection

Explanation:
According to Microsoft KB: All of the driver’s pool allocations are automatically tracked. At driver unload time, a bug check occurs if any of the allocations are not freed. You can then use the !verifier 3 kernel-debugger command to show all the allocations that are not freed. You can also use this command before unloading to view the outstanding allocations the driver has at any point in time.
