A storage administrator has presented thin LUNs to a vSphere cluster from an EMC Symmetrix VMAX array. The vSphere administrator then uses those thin LUNs to create VMFS partitions to store virtual disks. When the vSphere administrator creates new virtual machines, a new 100 GB virtual disk was also created. The virtual disks use 100 GB even though an operating system has not been installed on the guest. Why are the virtual disks using 100 GB of actual array space once they are created and before any data is put on them?

A.    Virtual disks have been formatted “Eagerzeroedthick”.
B.    Virtual disks have been formatted “Zeroedthick”.
C.    Virtual disks have been formatted “Thin” and zeroed on demand.
D.    vmkfstools was not used to format the disks.

Answer: A

A company has a Microsoft Exchange Server 2010 database running on Windows Server 2008. The Windows server contains users with dynamic mailbox growth requirements. In order to efficiently use capacity while still allowing room for extended growth, the company is considering implementing virtual provisioning on their Symmetrix VMAX for this specific mailbox database. The company is trying to determine which option to use when performing a volume format on the NTFS partition that will contain the mailbox database. Which option should be used and why?

A.    A quick format because it only performs a read request on the thin device and does not cause any space to be allocated.
B.    A quick format because it will not take as long as a regular format on thin devices.
C.    A regular format because it will write zeros to every block in the file system, causing the thin device to become fully allocated.
D.    A regular format because it will scan the entire volume for bad sectors.

Answer: A
