You want to install a new application on the Management Server. To achieve this, you need to increase the size of drive D.

Which utility should you use to perform this task without affecting the users accessing the data?

A.
Diskpart.exe

B.
Chkdsk.exe

C.
Fsutil.exe

D.
Fdisk.exe

Explanation:
You should use the Diskpartexe command. The Diskpart utility enables a superset of the actions that are supported by the Disk Management snap-in. You can use the Diskpartexe utility to manage disks, partitions, and volumes from a command-line interface. You can use Diskpartexe on both basic and dynamic disks. To extend a volume, you should use the extend [size=/7] [disk=/7] parameter with the Diskpartexe utility. The Extend parameter extends the selected volume onto disk n, and make the extension size=/7 megabytes (MB) in size. This task can also be performed by using the Extend Volume Wizard in the Disk Management snap-in.

You should not use the Chkdsk.exe command because this command cannot be used to increase the size of a partition. Chkdsk.exe creates and displays a status report for a disk based on the file system. The Chkdsk.exe utility also lists and corrects errors on the disk.

You should not use the Fsutil.exe command. Fsutil.exe performs many FAT and NTFS file system-related tasks, such as managing reparse points, managing sparse files, dismounting a volume, or extending a volume. However, the Fsutil.exe utility cannot be used to extend a volume without affecting the users accessing the data from that volume.

You should not use the Fdisk.exe command because this utility cannot be used to increase the size of an existing partition. Fdisk.exe partitions a hard disk. You can use the Fdisk.exe utility to create, change, delete, or display current partitions on the hard disk and to assign a drive letter to each allocated space on the hard disk.
