질문 # 122

정답：A


질문 # 123
Which of the following resources can be limited by libvirt for a KVM domain? (Choose two.)

정답：A,E

설명：
Libvirt is a toolkit that provides a common API for managing different virtualization technologies, such as KVM, Xen, LXC, and others. Libvirt allows users to configure and control various aspects of a virtual machine (also called a domain), such as its CPU, memory, disk, network, and other resources. Among the resources that can be limited by libvirt for a KVM domain are:
* Amount of CPU time: Libvirt allows users to specify the number of virtual CPUs (vCPUs) that a domain can use, as well as the CPU mode, model, topology, and tuning parameters. Users can also set the CPU shares, quota, and period to control the relative or absolute amount of CPU time that a domain can consume. Additionally, users can pin vCPUs to physical CPUs or NUMA nodes to improve performance and isolation. These settings can be configured in the domain XML file under the <cpu> and <cputune> elements12.
* Size of available memory: Libvirt allows users to specify the amount of memory that a domain can use, as well as the memory backing, tuning, and NUMA node parameters. Users can also set the memory hard and soft limits, swap hard limit, and minimum guarantee to control the memory allocation and reclaim policies for a domain. These settings can be configured in the domain XML file under the <memory>, <memoryBacking>, and <memtune> elements13.
The other resources listed in the question are not directly limited by libvirt for a KVM domain. File systems allowed in the domain are determined by the disk and filesystem devices that are attached to the domain, which can be configured in the domain XML file under the <disk> and <filesystem> elements14. Number of running processes and number of available files are determined by the operating system and the file system of the domain, which are not controlled by libvirt.

질문 # 124
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?

정답：D


질문 # 125
Which of the following mechanisms are used by LXC and Docker to create containers? (Choose three.)

정답：A,C,E

설명：
Explanation
LXC and Docker are both container technologies that use Linux kernel features to create isolated environments for running applications. The main mechanisms that they use are:
* Linux Capabilities: These are a set of privileges that can be assigned to processes to limit their access to certain system resources or operations. For example, a process with the CAP_NET_ADMIN capability can perform network administration tasks, such as creating or deleting network interfaces. Linux
* capabilities allow containers to run with reduced privileges, enhancing their security and isolation.
* Kernel Namespaces: These are a way of creating separate views of the system resources for different processes. For example, a process in a mount namespace can have a different file system layout than the host or other namespaces. Kernel namespaces allow containers to have their own network interfaces, process IDs, user IDs, and other resources, without interfering with the host or other containers.
* Control Groups: These are a way of grouping processes and applying resource limits and accounting to them. For example, a control group can limit the amount of CPU, memory, disk I/O, or network bandwidth that a process or a group of processes can use. Control groups allow containers to have a fair share of the system resources and prevent them from exhausting the host resources.
POSIX ACLs and file system permissions are not mechanisms used by LXC and Docker to create containers.
They are methods of controlling the access to files and directories on a file system, which can be applied to any process, not just containers.

질문 # 126
Which of the following statements in aDockerfileleads to a container which outputs hello world? (Choose two.)

정답：A,D

설명：
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:
