Which three are requirements when using vMotion to move a virtual machine across vCenter Server systems? (Choose three.)

Enhanced Linked Mode is required for cross-vCenter vMotion because it enables both vCenter Servers to share a unified inventory view, allowing the destination vCenter to appear as a valid migration target during the live migration workflow.

Both vCenter Servers must belong to the same Single Sign-On domain so that authentication tokens are mutually trusted between systems, which is a mandatory prerequisite for authorizing the cross-vCenter vMotion session.

Time synchronization via NTP is required because vSphere uses timestamps for Kerberos-based authentication and session tokens - a skew greater than the allowed threshold between hosts or vCenter servers will cause the vMotion handshake to fail.

Duplicate VM MAC addresses are never a valid configuration requirement and would cause network collisions on the destination segment - unique MAC addresses must be preserved across the migration.

High Availability is a cluster-level feature that restarts VMs on host failure and has no dependency relationship with vMotion - HA does not need to be enabled on either cluster to perform a live migration.
