質問 # 123
Which value must be set in the option builder in the configuration file of a Xen guest domain in order to create a fully virtualized machine instead of a paravirtualized one?
正解：
解説：
builder = "hvm"
Explanation:
In Xen virtualization, guest domains can be created using either paravirtualization (PV) or hardware-assisted full virtualization, also known as HVM (Hardware Virtual Machine). According to official Xen documentation, the builder option in a Xen guest domain configuration file determines the type of virtualization used when creating a virtual machine.
To create a fully virtualized (HVM) guest, the configuration file must explicitly set the value of the builder option to "hvm":
builder = "hvm"
This instructs the Xen toolstack to use hardware-assisted virtualization features provided by the CPU, such as Intel VT-x or AMD-V, allowing unmodified guest operating systems to run. Fully virtualized guests behave like physical machines and can run operating systems that are unaware of Xen.
If the builder option is omitted or set to the default paravirtualized builder, Xen expects a PV-capable kernel, which requires guest operating system modifications. HVM guests, by contrast, rely on device emulation and hardware virtualization support.
Virtualization documentation clearly distinguishes between PV and HVM guests and identifies builder =
"hvm" as the required configuration for full virtualization. This setting is fundamental when deploying operating systems such as Windows or standard Linux distributions without Xen-specific kernels.
Therefore, the correct and documented value is builder = "hvm".
質問 # 124
Which CPU flag indicates the hardware virtualization capability on an AMD CPU?
正解：B
解説：
Explanation
The CPU flag that indicates the hardware virtualization capability on an AMD CPU is SVM. SVM stands for Secure Virtual Machine, and it is a feature of AMD processors that enables the CPU to run virtual machines with hardware assistance. SVM is also known as AMD-V, which is AMD's brand name for its virtualization technology. SVM allows the CPU to support a hypervisor, which is a software layer that creates and manages virtual machines. A hypervisor can run multiple virtual machines on a single physical machine, each with its own operating system and applications. SVM improves the performance and security of virtual machines by allowing the CPU to directly execute privileged instructions and handle memory access, instead of relying on software emulation or binary translation. SVM also provides nested virtualization, which is the ability to run avirtual machine inside another virtual machine. To use SVM, the CPU must support it and the BIOS must enable it. The user can check if the CPU supports SVM by looking for the svm flag in the /proc/cpuinfo file or by using the lscpu command. The user can also use the virt-host-validate command to verify if the CPU and the BIOS are properly configured for hardware virtualization123. References:

質問 # 125
Which directory is used bycloud-initto store status information and configuration information retrieved from external sources?
正解：E
質問 # 126
What is the name of the kernel module that is required to be loaded in order to use KVM on an Intel CPU architecture?
(Specify ONLY the module name without any path information and with or without the module suffix.) Solution:
kvm-intel.ko - or - kvm-intel - or - kvm_intel.ko - or - kvm_intel
Determine whether the given solution is correct?
正解：B
解説：
Kernel-based Virtual Machine (KVM) relies on hardware-assisted virtualization features provided by modern CPUs. OnIntel CPU architectures, this support is enabled through thekvm_intelkernel module. Official KVM and Linux virtualization documentation clearly states that the required module for Intel processors is namedkvm_intel, with the optional .ko suffix when referring to the kernel object file.
The provided solution lists multiple acceptable representations of the module name, includingkvm_inteland kvm_intel.ko, both of which are valid and correct. Linux kernel module naming conventions allow the module to be referenced with or without the .ko suffix when loading it using tools such as modprobe or lsmod.
Although variants using a hyphen (kvm-intel) are not the canonical kernel module name, the solution explicitly includes the correct and documented module name. Therefore, the solutioncorrectly identifies the required kernel modulefor enabling KVM on Intel CPUs.
Virtualization documentation emphasizes that KVM functionality requires both the generic kvm module and the CPU-specific module (kvm_intel for Intel or kvm_amd for AMD). Hence, the determination that the solution iscorrectaligns with verified documentation.
質問 # 127
Which of the following commands deletes all volumes which are not associated with a container?
正解：B
解説：
Explanation
The command that deletes all volumes which are not associated with a container is docker volume prune. This command removes all unused local volumes, which are those that are not referenced by any containers. By default, it only removes anonymous volumes, which are those that are not given a specific name when they are created. To remove both unused anonymous and named volumes, the --all or -a flag can be added to the command. The command will prompt for confirmation before deleting the volumes, unless the --force or -f flag is used to bypass the prompt. The command will also show the total reclaimed space after deleting the volumes12.
The other commands listed in the question are not valid or do not have the same functionality as docker volume prune. They are either made up, misspelled, or have a different purpose. These commands are:
* docker volume cleanup: This command does not exist in Docker. There is no cleanup subcommand for docker volume.
* docker volume orphan -d: This command does not exist in Docker. There is no orphan subcommand for docker volume, and the -d flag is not a valid option for any docker volume command.
* docker volume vacuum: This command does not exist in Docker. There is no vacuum subcommand for docker volume.
* docker volume garbage-collect: This command does not exist in Docker. There is no garbage-collect subcommand for docker volume.

* docker volume prune | Docker Docs
