You are the systems administrator for your company. The network contains a server running Windows Small Business Server (SBS) 2003. You back up some important data on Windows SBS 2003 and store it on a tape drive.

You migrate from Windows SBS 2003 to Windows Essential Business Server 2008. A server named Serverl is configured as the Management Server. You want to restore data stored on the tape drive to Serverl.

Which files should you restore to Serverl?

A.
files with a .bck extension

B.
files with a .bkf extension

C.
files with a .bak extension

D.
files with a .bkp extension

Explanation:
You should restore the files with a .bkf extension. Windows SBS 2003 uses Windows Backup or the Ntbackup.exe utility for backup and restore. A backup created by using Windows Backup or the Ntbackup.exe utility has a .bkf extension. A backup file in .bkf format or in a backup tape created by using the Ntbackup.exe utility is a proprietary format that can be read by the Ntbackup.exe utility only. Backups with .bkf extensions cannot be restored using the Windows Server Backup utility available in Windows Server 2008. Therefore, you should download and install the Ntbackup.exe utility on Serverl.

All other options are incorrect because .bck, .bak, and .bkp are not valid extensions for backups created using Windows Backup or the Ntbackup.exe utility. A backup created with either Windows Backup or the Ntbackup.exe utility has a .bkf extension. Therefore, you should restore files with a .bkf extension.
