A company runs a single application on a dedicated physical server that is only utilized at 10% capacity. They want to reduce hardware costs and improve resource utilization by running multiple isolated applications on one server. However, the applications have different operating system requirements. What is the most appropriate solution?

Keep the applications on separate physical servers to avoid any performance overhead.

Use a Type 2 hypervisor on a desktop OS and run all applications in VMs on that host.

Use virtualization to run each application in its own VM with its required OS.

Use containers to run all applications on a single Linux host, sharing the kernel.

An administrator needs to move a running production VM from one KVM host to another to perform maintenance on the first host. The VM runs a critical database with in-memory state that must not be lost. The two hosts share the same storage pool. Which migration method should the administrator use?

Live migration: transfer the VM's memory state to the new host while it continues running, then switch over with minimal downtime.

Warm migration: pause the VM, copy memory and disk, then resume on the new host.

Snapshot the VM, copy the snapshot to the new host, and start the VM from the snapshot.

Cold migration: shut down the VM, copy its disk to the new host, and start it there.

What is the primary purpose of Open vSwitch in a virtualized environment?

To provide a hypervisor for running VMs

To provide a virtual switch for connecting VMs and containers

To manage virtual machine snapshots

To convert virtual disks to physical disks

A network administrator is setting up a virtualized environment with multiple VMs that need to communicate with each other and with the physical network. The administrator wants to implement VLAN tagging, traffic shaping, and monitoring at the virtual switch level. Which component should be used?

Open vSwitch (OVS) configured as the virtual switch for the hypervisor.

A physical network switch configured with VLANs and connected to the hypervisor.

The hypervisor's built-in virtual network adapter (vNIC) configured directly.

A standard Linux bridge (br0) configured with ip commands.
