drive is configured as a basic disk and has two partitions. Partition C is 2 GB in size and contains the operating system files. Partition D is 16 GB in size and contains user data that is updated frequently.

Both partitions are formatted as NTFS. Both partitions are backed up to a tape every evening at 10:00 P.M.You have a current Emergency Repair Disk (ERD) for EzonexamSrv, and the Recovery Console is installed on the computer.

One day at4:00 P.M., the server fails. You attempt to restart EzonexamSrv, but you receive the following error message:

"Boot disk or operating system not found".

You use Recovery Console to discover that the files on partition C are corrupted.

You need to recover EzonexamSrv from the failure as quickly as possible. You also must recover as much user data as possible.

What should you do？

A．Use the ERD to start the computer. Replace the corrupted files on partition C by copying them from a Windows 2000 Server CD-ROM.

B．Boot the Recovery Console. Copy any files that have changed since 10:00 P.M. the previous evening to a second server. Use the most recent tape backup to restore the remaining user data to the second server.

C．Start the computer by using a Windows 2000 Server CD-ROM. Select the Repair option in Setup.

D．Install a second hard disk in the computer. Install Windows 2000 Server on the new hard disk. Re-create the shared folders on the first hard disk.

Professional. You successfully upgrade computer1. During the upgrade of computer2, a series of power outages interrupts the upgrade.

You discover that the upgrade of computer2 is incomplete. Furthermore, you find that computer2 can no longer run Windows NT workstation 4.0. Computer2 does not support booting from the Windows 2000 Professional CD-ROM. You decide to use computer1 to help recover the failed upgrade.

What should you do？

A．On computer1, copy the CD-ROM driver and system files named ntdetect, ntbootdd.sys, Ntdll.dll and Setupldr.bin to a formatted floppy disk. On computer2, restart the computer by using the floppy disk. Then run WinNT32/debug from the Windows 2000 Professional CD-ROM.

B．From computer1, copy the CD-ROM driver and system files named Ntdetect, Ntbootdd.sys, Ntdll.dll, and Setupldr.bin to a formatted floppy disk. On the computer2, restart the upgrade by using the floppy disk. Then run WinNT32/rx from the Windows 2000 Professional CD-ROM.

C．On the computer1, run Makebt32.exe from the Bootdisk folder on the Windows 2000 Professional CD-ROM. On computer2, restart the upgrade by using the newly created floppy disks.

D．On computer1, perform. a remote installation from a network share. On computer2, when the text portion of setup has completed, resume the installation by using the Setup Manager.
