8. Which of the following statements are true regarding VirtualBox?

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.

12. Which of the following are true regarding the CPU of a QEMU virtual machine? (Choose two.)

The CPU architecture of a QEMU virtual machine is independent of the host system's architecture.

Each QEMU virtual machine can only have one CPU with one core.

For each QEMU virtual machine, one dedicated physical CPU core must be reserved.

QEMU uses the concept of virtual CPUs to map the virtual machines to physical CPUs.

QEMU virtual machines support multiple virtual CPUs in order to run SMP systems.

13. How does Packer interact with system images?

Packer has to be installed within the target image and is executed during the image's first boot in order to execute preparation tasks.

Packer installs a client within the image which has to be run periodically via cron in order to retrieve the latest template from the Packer server and apply it locally.

Packer periodically connects through the network to the Packer daemons of all running Packer images in order to re-apply the whole template to the running instance.

Packer downloads and extracts an image in order to make changes to the image's file system, repack the modified image and upload it again.

Packer creates an instance based on a source image, prepares the instance through a network connection and bundles the resulting instance as a new system image.

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

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.
