Which of the following server types would be an ideal candidate for virtualization? (Select two.)

A hypervisor is the software that creates and runs virtual machines; it is the platform for virtualization, not a server type to be virtualized itself.

While terminal servers can be virtualized, they often host many concurrent user sessions and can be very resource-intensive, particularly in terms of CPU and memory, making them less universally 'ideal' if not properly sized and managed.

Mail servers are often excellent candidates for virtualization because they can benefit significantly from resource sharing, live migration capabilities, and simplified management inherent in virtualized environments, typically having predictable and scalable performance requirements. Organizations virtualize mail servers to consolidate hardware and improve resilience.

Enterprise database servers, especially those with variable workloads or requiring high availability and easy scaling, can be ideal for virtualization; modern hypervisors and storage solutions can meet their demanding I/O and CPU requirements, allowing for snapshotting and migration benefits.

Domain controllers can be virtualized and it's a common practice, but they require specific considerations and careful planning to avoid issues like time synchronization problems and USN rollback, making them less universally 'ideal' without specific caveats compared to mail or database servers.
