An administrator needs to move a VM from one host to another, but the two hosts do not share storage. The VM must remain available during the migration, but a brief pause of a few seconds is acceptable. Which migration method is most appropriate?

Live migration with shared storage: transfer memory while the VM runs.

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

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

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

A small hosting provider wants to manage multiple KVM hosts and VMs through a centralized web interface, including live migration and high availability. They also need to manage virtual networking across hosts. Which combination of tools best fits this requirement?

Use Proxmox VE for centralized management and standard Linux bridges for networking.

Use VirtualBox for centralized management and standard Linux bridges for networking.

Use oVirt for centralized management and Open vSwitch for virtual networking.

Use systemd-machined for centralized management and Open vSwitch for networking.

A system administrator manages a KVM host running several VMs. One VM runs a batch job that is known to consume excessive CPU and memory, potentially starving other VMs. The administrator wants to ensure the batch VM cannot exceed a specific CPU share and memory limit, while other VMs remain responsive. Which feature should the administrator configure?

Configure CPU and memory resource limits (cgroups) for the batch VM.

Pause the batch VM when it is not in use.

Clone the batch VM and run the clone instead.

Enable snapshots for the batch VM so it can be rolled back if it misbehaves.

What is the effect of pausing (suspending) a virtual machine?

The VM's resources are permanently released

The VM's state is saved and execution stops

A company runs a mix of legacy and modern operating systems in a virtualized environment. The legacy OS does not support paravirtualization drivers, and the modern OS does. The hypervisor supports both full virtualization (with hardware assistance) and paravirtualization. The administrator wants to optimize performance for both types of guests. What is the best strategy?

Run all guests using full virtualization with hardware assistance, regardless of OS support.

Run the legacy OS with full virtualization and the modern OS with paravirtualization.

Use containers for the modern OS and full virtualization for the legacy OS.

Run all guests using paravirtualization, even if the legacy OS does not support it.
