질문 # 120
Which statement is true regarding the Linux kernel module that must be loaded in order to use QEMU with hardware virtualization extensions?

A. 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
B. It must be loaded into the kernel of each virtual machine to provide Para virtualization which is required by QEMU.
C. 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
D. It must be loaded into the kernel of each virtual machine that will access files and directories from the host system's file system.
E. It must be loaded into the Kernel of the host system in order to use the visualization extensions of the host system's CPU

정답：E

설명：
Explanation
The Linux kernel module that must be loaded in order to use QEMU with hardware virtualization extensions is KVM (Kernel-based Virtual Machine). KVM is a full virtualization solution that allows a user space program (such as QEMU) to utilize the hardware virtualization features of various processors (such as Intel VT or AMD-V). KVM consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. KVM must be loaded into the kernel of the host system in order to use the virtualization extensions of the host system's CPU. This enables QEMU to run multiple virtual machines with unmodified Linux or Windows images, each with private virtualized hardware. KVM is integrated with QEMU, so there is no need to load it into the kernel of each virtual machine or the first virtual machine. KVM also does not require paravirtualization, which is a technique that modifies the guest operating system to communicate directly with the hypervisor, bypassing the emulation layer. References:
* Features/KVM - QEMU
* Kernel-based Virtual Machine
* KVM virtualization on Red Hat Enterprise Linux 8 (2023)

질문 # 121
What is the default provider of Vagrant?

A. docker
B. lxc
C. vmware_workstation
D. virtualbox
E. hyperv

정답：D

설명：
Vagrant is a tool that allows users to create and configure lightweight, reproducible, and portable development environments. Vagrant supports multiple providers, which are the backends that Vagrant uses to create and manage the virtual machines. By default, VirtualBox is the default provider for Vagrant.
VirtualBox is still the most accessible platform to use Vagrant: it is free, cross-platform, and has been supported by Vagrant for years. With VirtualBox as the default provider, it provides the lowest friction for new users to get started with Vagrant. However, users can also use other providers, such as VMware, Hyper- V, Docker, or LXC, depending on their preferences and needs. To use another provider, users must install it as a Vagrant plugin and specify it when running Vagrant commands. Users can also change the default provider by setting the VAGRANT_DEFAULT_PROVIDER environmental variable. References:
* Default Provider - Providers | Vagrant | HashiCorp Developer1
* Providers | Vagrant | HashiCorp Developer2
* How To Set Default Vagrant Provider to Virtualbox3

FILL BLANK
Which subcommand ofvirshopens the XML configuration of a virtual network in an editor in order to make changes to that configuration? (Specify ONLY the subcommand without any parameters.)

정답：

설명：
net-edit

질문 # 123
Which of the following statements in aDockerfileleads to a container which outputs hello world? (Choose two.)

A. ENTRYPOINT "echo Hello World"
B. ENTRYPOINT [ "echo hello world" ]
C. ENTRYPOINT [ "echo", "hello", "world" ]
D. ENTRYPOINT echo Hello World
E. ENTRYPOINT "echo", "Hello", "World*

정답：B,C

질문 # 124
Which of the following statements are true for full virtualization? (Choose TWO correct answers)

A. Full virtualization always requires additional software components and cannot be done using Linux only
B. Full virtualization may be supported by special CPU extensions that provide better performance
C. Full virtualization does not require changes to the guest operating systems
D. Full virtualization has a severe performance impact and should not be used in production environments
E. Full virtualization has no performance impact compared to a non-virtualized bare-metal installation on the same machine

정답：B,C

설명：
Full virtualization is a virtualization approach where the hypervisor provides a complete simulation of the underlying hardware, allowingunmodified guest operating systemsto run without awareness of virtualization. Virtualization documentation consistently states that one of the defining characteristics of full virtualization is thatguest operating systems do not need to be modified, making optionCcorrect.
Additionally, modern full virtualization platforms benefit fromhardware-assisted virtualization, such as Intel VT-x and AMD-V CPU extensions. These extensions significantly improve performance by offloading virtualization tasks to the processor, making optionBcorrect.
Option A is incorrect because Linux-based hypervisors like KVM can perform full virtualization entirely within the Linux ecosystem. Option D is false because all virtualization introduces some performance overhead, even if minimal. Option E is incorrect because full virtualization is widely used in production environments, including enterprise data centers and cloud platforms.
Therefore, based on virtualization principles and documentation, the correct answers areB and C.
