220-1101 Virtualization and Cloud Computing Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  Initialize disks, then create mirrored volume, then format the volume, then verify.

  Why this is correct

  Initialization is the prerequisite step because Windows must write a disk signature and partition table (MBR or GPT) to the physical disk before the disk can be recognized by the storage subsystem. After both disks are initialized, the mirrored volume is created, which reserves the same logical space on each disk and establishes the mirroring relationship. Formatting then assigns a file system, such as NTFS or ReFS, so the volume can store files, and verification checks the volume status to confirm the mirror is synchronized and healthy.

• ✗

  Create mirrored volume, then initialize disks, then format the volume, then verify.

  Why it's wrong here

  This sequence is invalid because creating a mirrored volume requires the disks to already be online and have a valid disk signature; Windows will fail to allocate the needed extents on uninitialized disks. Initialization also activates the disk for use with dynamic storage, and without it the 'New Mirrored Volume' wizard cannot select the destination disks. Even if the wizard somehow proceeded, the underlying storage would be inconsistent because the disk signature is what allows the OS to consistently track the members of the mirror set.

• ✗

  Initialize disks, then format the volume, then create mirrored volume, then verify.

  Why it's wrong here

  Formatting cannot be performed before the volume exists because formatting acts on a logical volume object (a drive letter or mount point) to install a file system; if you try to format a bare partition on one disk, you only create an independent partition with no fault tolerance. The mirrored volume must be created first to logically combine the same region on both disks and to expose a single volume object to the file system formatter. Attempting to format before creation would either fail with 'The operation is not available' or silently produce a non-mirrored disk, defeating the purpose of RAID 1.

• ✗

  Initialize disks, then create mirrored volume, then verify, then format the volume.

  Why it's wrong here

  Verification of a mirrored volume checks that the file system is intact and the mirror relationship is synchronized; an unformatted volume has no file system to validate, so the verification step would fail or return meaningless results. Additionally, the act of formatting writes metadata to the volume and may trigger a resynchronization of the mirror, meaning a verification performed before formatting could report an outdated or inconsistent state. Therefore, the correct logical order is to create the volume, format it, and only then verify redundancy and readability.
