Q:

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 0, 1, and 2. D) Configure SQL Server to use only processors 1, 2, and 3.

Answer:   D) Configure SQL Server to use only processors 1, 2, and 3.

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.

Note 1: The Affinity mask is used to exclude a processor on a multiprocessor computer from processing SQL Server 2000 threads. Default is equal distribution of SQL Server 2000 processes across all processors.

Note 2: Monitoring the Processor and System object counters provides information about the CPU utilization and helps in determining whether or not a bottleneck exists. The %Total Processor Time is used on multiple CPU Severs to gauge the average activity of the processors and shows the percentage of elapsed time that a processor is busy executing a nonidle thread. Values around 100 percent on a Server computer that processes many client requests indicate that processes are queuing up, waiting for processor time, and causing a bottleneck. Such a sustained high level of processor usage is unacceptable for a server.

Q:

Q:

You are installing Windows 2000 on a computer that already has another operating system installed on it. You choose to install Windows 2000 in a different folder than the previously installed operating system. What will Windows 2000 do?

A) Abort the installation process B) Delete the previously installed operating system
C) Display an error message indicating that windows 2000 cannot be installed in a different folder D) Cause the computer to dual boot between Windows 2000 and the previously installed operating system
 
Answer & Explanation Answer: D) Cause the computer to dual boot between Windows 2000 and the previously installed operating system

Explanation:

When windows 2000 is installed in the same folder as the other operating system, Windows 2000 will delete the previously installed operating system. When Windows 2000 is installed in a different folder than the other operating system, it will automatically configure the computer to dual boot between Windows 2000 and the previously installed operating system.

Q:

You create a mirrored volume on a Windows 2000 Server computer. What additional item should you create?

A) A new Config.nt file B) A new Auto exec.nt file
C) A fault tolerance boot disk D) A set of Windows 2000 Setup Boot Disks
 
Answer & Explanation Answer: C) A fault tolerance boot disk

Explanation:

A fault tolerance boot disk is a floppy disk that you create that enables you to boot your Windows 2000 computer in the event that the first disk in your computer's mirrored volume fails. This disk contains an edited copy of the Boot.ini file.

Q:

You want to implement Active Directory on your Windows 2000 network. Your network consists of Windows 2000 Server computers, Windows 2000 Professional computers, Windows NT Workstation 4.0 computers, and Windows 98 computers. You want to achieve optimum functionality of all the client computers with Active Directory. What should you do?

A) Install the Directory Service Client on all of the Windows 98 computers. B) Upgrade all of the Windows 98 computers to Windows 2000 Professional
C) Upgrade all of the Windows NT Workstation 4.0 computers and Windows 98 computers to Windows 2000 Professional D) Nothing. Windows 2000 will automatically detect all client computers and optimize them to function with Active Directory.
 
Answer & Explanation Answer: C) Upgrade all of the Windows NT Workstation 4.0 computers and Windows 98 computers to Windows 2000 Professional

Explanation:

To achieve optimum functionality of the client computers, you must upgrade all of them to Windows 2000. Upgrading some of them and/or installing the Directory Service Client will gain some functionality, but the question specifically states that "optimum functionality" is the required result.
