Final answer:
A freshly installed ESXi 6 host uses the GUID partition table (GPT) which is true. GPT offers advantages such as supporting larger disk sizes compared to the older MS-DOS partition label.
Step-by-step explanation:
True, a freshly installed ESXi 6 host does indeed use the GUID partition table (GPT) format instead of the MS-DOS style partition label for the disk. GPT is a newer partitioning scheme with many advantages over the older Master Boot Record (MBR) format, also known as MS-DOS partition label.
These include support for larger disk sizes and more partitions per disk. VMware's ESXi is a hypervisor used to virtualize servers, and as such, it benefits from using a partition table scheme that is more suitable for modern computing environments.
