Кто-нибудь знает правильный ответ на вопрос который приводится ниже? В разных braindump-ах по разному - где c, где d. Может кто-нибудь обоснует?

27.You are the administrator of a Microsoft Windows NT Server 4 0 computer
The server is the PDC in your domain and also runs SQL Server 2000. The
server has four processors and 1 GB of RAM. Your network consists of 500
client computers that are running Microsoft Windows Millennium Edition.
Users report that when they log on in the morning their computers respond
slowly and occasionally return error messages. You use System Monitor to
monitor processor performance and RAM utilization You discover that the %
Total Time and % User Time counters average 90 percent and the %
Privileged Time counter averages 20 percent. The Available Mbytes counter
averages 800 MB. You need to improve server performance for user logons.
What should you do?

a. Increase the physical RAM on the computer to 2 GB
b. Increase the virtual RAM on the computer to 4 GB
c. Configure SQL Server to use only processors 1,2, and 3
d. Configure SQL Server to use only processors 0, 1, and 2

Я поискал и сам нашел такое обьяснение(думаю оно правильное):

Answer: C
Explanation: The system monitor clearly indicates that the processors are overloaded. We need to decide which processors we should use for SQL Server.
Processor 0 is the default CPU for the I/O subsystem. Network Interface Cards (NIC) are assigned to the remaining CPUs, starting from the highest-numbered CPU. The NIC would get processor 3. SQL Server would be using all four processors by default.

The Windows NT/2000/XP operating system use processor 0. In order to avoid the logon problems we should not let SQL Server to use this processor. Instead SQL Server should be configured to use processor 1,
2, and 3.
