Explanation

Virtual hosts (VMs) with differing security requirements must be stored on separate physical hosts to enforce true isolation. When VMs of different trust levels share the same physical hardware, a compromise of the lower-security VM can potentially escalate to the higher-security VM through VM escape attacks, shared CPU caches (side-channel attacks like Spectre/Meltdown), or hypervisor vulnerabilities. Physical separation eliminates this risk entirely. Answer A (one-time passwords) addresses authentication, not isolation. Answer C (moving to the cloud) does not resolve the co-tenancy problem. Answer D (vulnerability scanning) is a good practice but does not prevent cross-VM compromise from hardware sharing.
