Option available to enable Encrypted vMotion (Choose two)

'Enable' is not a valid Encrypted vMotion setting; the three actual options are Disabled, Opportunistic, and Required.

Opportunistic encrypts vMotion traffic only when both the source and destination ESXi hosts support encryption, falling back to unencrypted migration if one host lacks support, providing a best-effort security posture.

Required enforces encryption for all vMotion migrations and will block the migration entirely if either host does not support encrypted vMotion, ensuring no live migration traffic ever travels in plaintext.

'Default' is not a valid Encrypted vMotion option in vSphere; it is not one of the three choices presented in the VM's vMotion encryption configuration.
