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.)
正解：
解説：
net-edit
Explanation:
The subcommand of virsh that opens the XML configuration of a virtual network in an editor in order to make changes to that configuration is net-edit1. This subcommand takes the name or UUID of the network as a parameter and opens the network XML file in the default editor, which is specified by the $EDITOR shell variable1. The changes made to the network configuration are applied immediately after saving and exiting the editor1.
:
1: net-edit - libvirt.

A clone of a previously used virtual machine should be created. All VM specific information, such as user accounts, shell histories and SSH host keys should be removed from the cloned disk image. Which of the following tools can perform these tasks?
正解：C
解説：
Explanation
Sysprep is a tool that removes all your personal account and security information, and then prepares the machine to be used as an image. It is supported by Windows and some Linux distributions. It can also remove drivers and other machine-specific settings. Sysprep is required when creating a managed image outside of a gallery in Azure

What is true aboutcontainerd?
正解：A
解説：
Containerd is an industry-standard container runtime that uses Runc (a low-level container runtime) by default, but can be configured to use others as well1. Containerd manages the complete container lifecycle of its host system, from image transfer and storage to container execution and supervision1. It supports the standards established by the Open Container Initiative (OCI)1. Containerd does not require the Docker engine and Docker CLI to be installed, as it can be used independently or with other container platforms2.
Containerd is not a text file format, nor does it run in each Docker container or provide DHCP client functionality. Containerd is not the initial process run at the start of any Docker container, as that is the role of the container runtime, such as Runc3. References: 1 (search for "containerd"), 2 (search for "Containerd is an open source"), 3 (search for "It uses rune to start containers").

Which of the following statements in aDockerfileleads to a container which outputs hello world? (Choose two.)
正解：C、E
解説：
Explanation
The ENTRYPOINT instruction in a Dockerfile specifies the default command to run when a container is started from the image. The ENTRYPOINT instruction can be written in two forms: exec form and shell form.
The exec form uses a JSON array to specify the command and its arguments, such as [ "executable",
"param1", "param2" ]. The shell form uses a single string to specify the command and its arguments, such as
"executable param1 param2". The shell form is converted to the exec form by adding /bin/sh -c to the beginning of the command. Therefore, the following statements in a Dockerfile are equivalent and will lead to a container that outputs hello world:
ENTRYPOINT [ "echo hello world" ] ENTRYPOINT [ "/bin/sh", "-c", "echo hello world" ] ENTRYPOINT
"echo hello world" ENTRYPOINT [ "echo", "hello", "world" ] ENTRYPOINT [ "/bin/sh", "-c", "echo",
"hello", "world" ] ENTRYPOINT "echo hello world"
The other statements in the question are invalid or incorrect. The statement A. ENTRYPOINT "echo Hello World" is invalid because it uses double quotes to enclose the entire command, which is not allowed in the shell form. The statement D. ENTRYPOINT echo Hello World is incorrect because it does not use quotes to enclose the command, which is required in the shell form. The statement E. ENTRYPOINT "echo", "Hello",
"World" is invalid because it uses double quotes to separate the command and its arguments, which is not allowed in the exec form. References:

質問 # 65
Which of the following commands boots a QEMU virtual machine using hardware virtualization extensions?
正解：D
解説：
Explanation
The correct command to boot a QEMU virtual machine using hardware virtualization extensions is qemu
-accel kvm -drive file-debian.img -cdrom debian.iso -m 1024 -boot d. This command uses the -accel option to specify the hardware accelerator to use, which in this case is kvm. KVM is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V)1. The -drive option specifies the disk image file to use, which in this case is debian.img. The -cdrom option specifies the ISO image file to use as a CD-ROM, which in this case is debian.iso. The -m option specifies the amount of memory to allocate to the virtualmachine, which in this case is 1024 MB. The -boot option specifies the boot order, which in this case is d, meaning to boot from the CD-ROM first. References:
