Your network contains a server named Server1 that runs Windows Server 2008 R2. You add a new 3-terabyte hard disk to Server1.
You need to create a 3-terabyte volume.
What should you do first?
A. Disable write caching for the hard disk.
B. Initialize the disk as a Master Boot Record (MBR) disk.
C. Initialize the disk as a GUID Partition Table (GPT) disk.
D. Disable direct memory access (DMA) for the hard disk controller.
Correct Answer: C
Explanation/Reference:
A GPT disk uses the GUID partition table (GPT) disk partitioning system. A GPT disk offers these benefits:
Allows up to 128 primary partitions. Master Boot Record (MBR) disks can support up to four primary partitions and an additional 124 partitions inside extended partitions.
Allows a much larger partition size–greater than 2 terabytes (TB), which is the limit for MBR disks.
Provides greater reliability because of replication and cyclical redundancy check (CRC) protection of the partition table.
Can be used as a storage volume on all x64-based platforms, including platforms running Windows XP Professional x64 Edition. Starting with Windows Server 2003 SP1, GPT disks can also be used as a storage volume on x86-based Windows platforms.
Can be used as a boot volume on x64-based editions of Windows 7, Windows Vista, and Windows Server 2008. Starting with Windows Server 2003 SP1, GPT disks can also be used as a boot volume on Itanium-based systems.
Note: Windows only supports booting from a GPT disk on systems that contain Unified Extensible Firmware Interface (UEFI) boot firmware.
