   An administrator needs to run two legacy applications that require different operating systems on a single physical server. The applications are not resource-intensive, and the administrator wants to minimize hardware costs. What is the most efficient way to achieve this?

   • ACreate two virtual machines on a hypervisor, each with the required OS.
   • BUse a container runtime to run both applications in isolated containers.
   • CPurchase two separate physical servers, one for each application.
   • DInstall both applications on the same OS using compatibility mode.

   An administrator is planning to deploy a virtualized environment. They have a choice between a Type 1 hypervisor and a Type 2 hypervisor. The environment will host production workloads that require high performance and reliability. Which factor is most important in this decision?

   • AType 2 hypervisors provide better isolation between VMs.
   • BType 1 hypervisors have lower overhead and better performance because they run directly on hardware.
   • CType 2 hypervisors are easier to install and manage.
   • DType 1 hypervisors support more guest operating systems.
