Lpi LPIC-3 Exam 305: Virtualization and Containerization Sample Questions (Q118-Q123):

NEW QUESTION # 118
Which of the following tasks is performed by Vagrant?

Answer: C

Explanation:
Vagrant is a tool designed toautomate the creation and provisioning of development virtual machines using a declarative configuration file called aVagrantfile. According to virtualization documentation, Vagrant simplifies setting up reproducible environments by automatically installing and configuring virtual machines based on this file.
Vagrant does not perform monitoring, reporting, hypervisor functions, or automatic VM migration. It integrates with providers such as VirtualBox, KVM, and VMware but is not itself a hypervisor.
Therefore, the correct answer isA.


NEW QUESTION # 119
Which file in acgroupdirectory contains the list of processes belonging to thiscgroup?

Answer: D


NEW QUESTION # 120
Which sub-command of xl changes the media inside a virtual CD-ROM drive of a Xen guest domain?
(Specify ONLY the sub-command without any path or parameters.)
Solution:
block-attach - or - xl cd-insert - or - cd-eject - or - xl cd-eject - or - cd-insert - or - xl block-attach - or - block-detach - or - xl block-detach Determine whether the given solution is correct?

Answer: B

Explanation:
According to official Xen xl toolstack documentation, thecorrect sub-commandsused to change media in a virtual CD-ROM drive arecd-insertandcd-eject. These commands are specifically designed for inserting or ejecting ISO media from a Xen guest's virtual CD-ROM device.
While commands such as block-attach and block-detach are valid xl sub-commands, they are used for attaching and detaching block devices in general and arenot specific to CD-ROM media operations. The provided solution lists multiple commands, including incorrect and unrelated ones, rather than specifying the correct sub-command precisely.
Because the solution does not accurately and exclusively identify the correct xl sub-command, it is considered incorrect. Therefore, the correct determination isB.
