Which statement is true regarding the Linux kernel module that must be loaded in order to use QEMU with hardware virtualization extensions?

It must be loaded into the Kernel of the host system in order to use the visualization extensions of the host system's CPU

It must be loaded into the kernel of the host system only if the console of a virtual machine will be connected to a physical console of the host system

It must be loaded into the kernel of each virtual machine that will access files and directories from the host system's file system.

It must be loaded into the Kernel of the host system in order to use the visualization extensions of the host system's CPU

It must be loaded into the kernel of the first virtual machine as it interacts with the QEMU bare metal hypervisor and is required to trigger the start of additional virtual machines

It must be loaded into the kernel of each virtual machine to provide Para virtualization which is required by QEMU.

How can data be shared between several virtual machines running on the same Linux-based host system?

By using a network file system or file transfer protocol.

By writing data to the file system since all virtual machines on the same host system use the same file system.

By mounting other virtual machines' file systems from /dev/virt-disks/remote/.

By setting up a ramdisk in one virtual machine and mounting it using its UUID in the other VMs.

By using a network file system or file transfer protocol.

By attaching the same virtual hard disk to all virtual machines and activating EXT4 sharing extensions on it.

Which of the following statements are true regarding resource management for full virtualization? (Choose two.)

The hypervisor provides each virtual machine with hardware of a defined capacity that limits the resources of the virtual machine.

It is up to the virtual machine to use its assigned hardware resources and create, for example, an arbitrary amount of network sockets.

The hygervisor may provide fine-grained limits to internal elements of the guest operating system such as the number of processes.

The hypervisor provides each virtual machine with hardware of a defined capacity that limits the resources of the virtual machine.

Full virtualization cannot pose any limits to virtual machines and always assigns the host system's resources in a first-come-first-serve manner.

All processes created within the virtual machines are transparently and equally scheduled in the host system for CPU and I/O usage.

It is up to the virtual machine to use its assigned hardware resources and create, for example, an arbitrary amount of network sockets.

Which of the following kinds of data can cloud-init process directly from user-data? (Choose three.)

cloud-config declarations in YAML

Base64-encoded binary files to execute

Which of the following statements are true about sparse images in the context of virtual machine storage? (Choose two.)

Sparse images may consume an amount of space different from their nominal size.

Sparse images allocate backend storage at the first usage of a block.

Sparse images are automatically shrunk when files within the image are deleted.

Sparse images may consume an amount of space different from their nominal size.

Sparse images can only be used in conjunction with paravirtualization.

Sparse images allocate backend storage at the first usage of a block.

Sparse images are automatically resized when their maximum capacity is about to be exceeded.

Which of the following statements are true regarding VirtualBox?

It provides both a graphical user interface and command line tools to administer virtual machines.

It is a hypervisor designed as a special kernel that is booted before the first regular operating system starts.

It only supports Linux as a guest operating system and cannot run Windows inside a virtual machine.

It requires dedicated shared storage, as it cannot store virtual machine disk images locally on block devices of the virtualization host.

It provides both a graphical user interface and command line tools to administer virtual machines.

It is available for Linux only and requires the source code of the currently running Linux kernel to be available.

Which of the following commands moves the libvirt domain web1 from the current host system to the host system host2?

virsh migrate web1 qemu+ssh://host2/system

virsh node-update host1=-dom:web1 host2=+dom:web1

virsh migrate web1 qemu+ssh://host2/system

virsh patch web1 .Domain.Node=host2

Which of the following types of guest systems does Xen support? (Choose two.)

Foreign architecture guests (FA)

Which of the following commands lists all differences between the disk images vm1-snap.img and vm1.img?

virt-diff -a vm1-snap.img -A vm1.img

virt-delta -a vm1-snap.img -A vm1.img

virt-cp-in -a vm1-snap.img -A vm1.img

virt-cmp -a vm1-snap.img -A vm1.img

virt-history -a vm1-snap.img -A vm1.img

virt-diff -a vm1-snap.img -A vm1.img
