Lpi LPIC-3 Exam 305: Virtualization and Containerization Sample Questions (Q62-Q67):

NEW QUESTION # 62
What is the purpose of the commandvagrant init?

Answer: A

Explanation:
Explanation
The command vagrant init is used to initialize the current directory to be a Vagrant environment by creating an initial Vagrantfile if one does not already exist1. The Vagrantfile contains the configuration settings for the Vagrant box, such as the box name, box URL, network settings, synced folders, provisioners, etc. The command vagrant init does not execute any provisioning tool, start any box, install Vagrant on a Linux host, or download any box. Those actions are performed by other Vagrant commands, such as vagrant provision, vagrant up, vagrant install, and vagrant box add, respectively. References:
* 1: vagrant init - Command-Line Interface | Vagrant | HashiCorp Developer


NEW QUESTION # 63
What kind of virtualization is implemented by LXC?

Answer: D

Explanation:
LXC implements system containers, which are a type of operating-system-level virtualization. System containers allow running multiple isolated Linux systems on a single Linux control host, using a single Linux kernel. System containers share the same kernel with the host and each other, but have their own file system, libraries, and processes. System containers are different from application containers, which are designed to run a single application or service in an isolated environment. Application containers are usually smaller and more portable than system containers, but also more dependent on the host kernel and libraries. Hardware containers, CPU emulation, and paravirtualization are not related to LXC, as they are different kinds of virtualization methods that involve hardware abstraction, instruction translation, or modification of the guest operating system. References:
* 1: LXC - Wikipedia
* 2: Linux Virtualization : Linux Containers (lxc) - GeeksforGeeks
* 3: Features - Proxmox Virtual Environment


NEW QUESTION # 64
Which of the following resources can be limited by libvirt for a KVM domain? (Choose two.)

Answer: A,B

Explanation:
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.

CPU Allocation
Memory Allocation

NEW QUESTION # 65
Which of the following statements are true regarding VirtualBox?

Answer: D


NEW QUESTION # 66
Which of the following statements about the commandlxc-checkpointis correct?

Answer: E

Explanation:
The command lxc-checkpoint is used to checkpoint and restore containers. Checkpointing a container means saving the state of the container, including its memory, processes, file descriptors, and network connections, to a file or a directory. Restoring a container means resuming the container from the saved state, as if it was never stopped. Checkpointing and restoring containers can be useful for various purposes, such as live migration, backup, debugging, or snapshotting. The command lxc-checkpoint has the following syntax:
lxc-checkpoint {-n name} {-D path} [-r] [-s] [-v] [-d] [-F]
The options are:
* -n name: Specify the name of the container to checkpoint or restore.
* -D path: Specify the path to the file or directory where the checkpoint data is dumped or restored.
* -r, --restore: Restore the checkpoint for the container, instead of dumping it. This option is incompatible with -s.
* -s, --stop: Optionally stop the container after dumping. This option is incompatible with -r.
* -v, --verbose: Enable verbose criu logging. Only available when providing -r.
* -d, --daemon: Restore the container in the background (this is the default). Only available when providing -r.
* -F, --foreground: Restore the container in the foreground. Only available when providing -r.
The command lxc-checkpoint uses the CRIU (Checkpoint/Restore In Userspace) tool to perform the checkpoint and restore operations. CRIU is a software that can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. It can then use the files to restore and run the application from the point it was frozen at1.
The other statements about the command lxc-checkpoint are not correct. It does not create a clone or an image of a container, nor does it double the memory consumption of the container. It can work on both running and stopped containers, depending on the options provided. References:
* Linux Containers - LXC - Manpages - lxc-checkpoint.12
* lxc-checkpoint(1) - Linux manual page - man7.org3
* CRIU4
