    Correct answer is A! You only change the format AFTER 2TB If it was 2.01 TB then yes the answer would be correct but it’s 2 TB even meaning A is the correct Answer.

    Ref: page 4, vsphere-50-configuration-maximums.pdf
    “Maximum file size for upgraded VMFS5 is 2TB minus 512 bytes, irrespective of the file‐system block “

    Sorry, but . . . i don’t understand. Answer “A” is “The maximum virtual disk size remains 512MB”, but I think that you replay about answer “B: The maximum virtual disk size increases to 2TB minus 512B”. It’s correct?

  4. Rich says:

    The correct answer seems to be a mash-up of A, C & D:

    “The maximum virtual disk size remains 512MB, but the maximum virtual disk size increases to 2TB minus 512B providing the datastore is also increased.”
