NEW QUESTION # 87
How do containers share the host OS kernel?
Answer: D
Explanation:
Containers operate bysharing the host operating system's kernelwhile running inisolated user spaces.
According to containerization documentation, Linux kernel features such asnamespaces and cgroupsprovide process isolation, resource control, and security boundaries between containers.
Each container has its own filesystem, process tree, and network stack, but all containers rely on the same underlying kernel. This design makes containers lightweight and efficient compared to virtual machines, which require separate guest kernels.
Options A and D are incorrect because containers do use the host kernel. Option C is incomplete because it does not mention isolation. Therefore, the correct answer isB.
NEW QUESTION # 88
The commandvirsh vol-list vmsreturns the following error:
error: failed to get pool 'vms'
error: Storage pool not found: no storage pool with matching name 'vms ' Given that the directory/vmsexists, which of the following commands resolves this issue?
Answer: C
Explanation:
Explanation
The command virsh pool-create-as vms dir --target /vms creates and starts a transient storage pool named vms of type dir with the target directory /vms12. This command resolves the issue of the storage pool not found error, as it makes the existing directory /vms visible to libvirt as a storage pool. The other commands are invalid because:
* dd if=/dev/zero of=/vms bs=1 count=0 flags=name:vms is not a valid command syntax. The dd command does not take a flags argument, and the output file /vms should be a regular file, not a directory3.
* libvirt-poolctl new --name=/vms --type=dir --path=/vms is not a valid command name. There is no such command as libvirt-poolctl in the libvirt package4.
* qemu-img pool vms:/vms is not a valid command syntax. The qemu-img command does not have a pool subcommand, and the vms:/vms argument is not a valid image specification5.
* touch /vms/.libvirtpool is not a valid command to create a storage pool. The touch command only creates an empty file, and the .libvirtpool file is not recognized by libvirt as a storage pool configuration file6.

NEW QUESTION # 89
Which file in acgroupdirectory contains the list of processes belonging to thiscgroup?
Answer: E
Explanation:
The file procs in a cgroup directory contains the list of processes belonging to this cgroup. Each line in the file shows the PID of a process that is a member of the cgroup. A process can be moved to a cgroup by writing its PID into the cgroup's procs file. For example, to move the process with PID 24982 to the cgroup cg1, the following command can be used: echo 24982 > /sys/fs/cgroup/cg1/procs1. The file procs is different from the file tasks, which lists the threads belonging to the cgroup. The file procs can be used to move all threads in a thread group at once, while the file tasks can be used to move individual threads2. References:
* Creating and organizing cgroups cgroup2 - GitHub Pages
* Control Groups - The Linux Kernel documentation
NEW QUESTION # 90
Which of the following statements about the commandlxc-checkpointis correct?
Answer: D
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
