質問 2：
How can data be shared between several virtual machines running on the same Linux-based host system?
A. By attaching the same virtual hard disk to all virtual machines and activating EXT4 sharing extensions on it.
B. By mounting other VM's file systems from /dev/virt-disks/remote/.
C. By setting up a ramdisk in one virtual machine and mounting it using its UUID in the other VMs.
D. By using a network file system or file transfer protocol.
E. By default, Linux-based virtualization products provide full access to the host system to all virtual machines.
正解：D

質問 5：
Which of the following statements describes the concept behind paravirtualization?
A. To avoid the need for virtualization, special security measures are taken to allow different applications to coexist on one physical machine.
B. Each operating system is trusted to use only those resources assigned to it, thereby eliminating the need of an additional virtualization layer.
C. Guest operating systems are modified to actively cooperate with the hypervisor in order to ease virtualization costs and gain better performance.
D. Instead of running full virtual machines, containers are used to separate distinct parts of one commonly shared operating system that appear as a virtual machine.
正解：C
