You are the network administrator for your company. All network servers run Windows Server 2003.The network includes a file server named File1. File1 contains a single disk for system files and two SCSIhard disks that comprise a 72-GB mirrored volume with 65 GB of read-only data. Users connect to thisdata by using shortcuts on their desktops.File1 is scheduled for replacement. You have a scheduled maintenance window to complete this task.Before the maintenance window, you build a new server.You need to bring the new server online with current data and re-establish redundancy as quickly aspossible. You must also ensure that the desktop shortcuts will continue to function.What should you do? ()A、Name the new server File2. Create a new mirrored volume by using two 72-GB disks. Connect File2 to the network and copy the data from File1. When copying is complete, shut down the old File1.B、Name the new server File1. Move both disks from the old File1 to the new File1. Scan the disks for changes. Import the disks. Connect the new File1 to the network.C、Name the new server File1. Break the mirror on the old File1. Move one of the disks from the old File1 to the new File1. Scan the disk for changes. Initialize the disk. Select the spare disk and create the mirror. Connect the new File1 to the network.D、Name the new server File1. Remove one of the disks in the mirror from the old File1. Move the disk to the new File1. Scan the disk for changes. Import the disk. Shut down the old File1 and connect the new File1 to the network.
