   A VCF administrator is preparing to add a new VCF Instance to an existing fleet. The pre-scaling validation fails, reporting insufficient storage capacity in the management domain. The administrator checks the management domain's datastores and finds that there is 2 TB of free space, which seems sufficient for the new instance. What is the most likely reason for the validation failure?

   • AThe datastores are formatted with VMFS5, but VCF requires VMFS6 for new instances.
   • BThe free space calculation includes snapshots that VCF cannot use for new deployments.
   • CThe management domain's storage policy requires a specific RAID level that the new instance cannot use.
   • DThe free space is spread across multiple datastores, but VCF requires a single datastore with sufficient contiguous space.

The administrator suspects that the instance's vCenter Server is still registered in the management domain. What should the administrator do to resolve this issue?

   • AManually unregister the vCenter Server from the management domain's SSO domain before retrying the removal.
