305-300 Exam Essentials: Frequently Asked Questions

Lpi LPIC-3 Exam 305: Virtualization and Containerization is an official LPI (Linux Professional Institute) certification exam, listed under the code 305-300. Clearing it earns the LPIC-3 certification, a Expert-level credential. It also ties into LPIC-3 Virtualization and Containerization, LPIC-2, which makes it a useful anchor for a longer certification plan. For employers, the value is simple: the vendor itself has verified what you know.

You will work through 60 questions in 90 minutes on the Lpi LPIC-3 Exam 305: Virtualization and Containerization exam. The content is only half the battle; the clock is the other half. Train both at once: set the ValidDumps test engine to full timed mode, practice skipping and returning to stubborn items, and repeat until finishing with minutes to spare feels normal rather than lucky.

Passing Lpi LPIC-3 Exam 305: Virtualization and Containerization requires 500 (scaled score, range 200-800), and the official registration fee is USD $132. Remember that a retake bills the same USD $132 all over again, so winging it is the most expensive strategy on the table. A better approach: benchmark yourself with the ValidDumps practice tests first, and schedule the real exam only once your scores sit comfortably and consistently above the requirement.

The candidate must have an active LPIC-2 certification to receive the LPIC-3 certification.

Requirements do evolve, so before you spend a registration fee, verify the current conditions on the official exam page.

Lpi LPIC-3 Exam 305: Virtualization and Containerization Sample Questions:

Question #1

Which command was used in Xen 3.x as a predecessor of the xl command?

Answer:

xm
Explanation:
In Xen 3.x, the primary command-line tool used to manage virtual machines wasxm. According to Xen virtualization documentation, xm was part of the original Xen management stack and provided commands to create, start, stop, migrate, and monitor Xen domains.
As Xen evolved, the xm toolstack was deprecated and replaced by thexltoolstack. The xl command interfaces directly with the Xen hypervisor and offers better performance, improved maintainability, and reduced complexity. Modern Xen installations no longer support xm, but it remains historically significant as the predecessor to xl.
Therefore, the correct answer isxm.

Question #2

Which of the following tasks is performed by Vagrant?

  • A. It migrates virtual machines automatically between host systems
  • B. It is a programming interface used to create reports from collected performance data
  • C. It is a hypervisor optimized for embedded ARM systems
  • D. It monitors the functionality of a virtual machine and restarts the VM in case of failure
  • E. It automates the installation of a virtual machine according to a configuration file describing the desired VM
Answer: E

Question #3

Which virsh subcommand is used to change the CD-ROM image file attached to a virtual machine?

Answer:

change-media
Explanation:
In libvirt-based virtualization environments, thevirsh change-mediasubcommand is used to change the media attached to removable devices such asCD-ROM drives. According to libvirt documentation, this command allows administrators to insert or eject ISO images from a running virtual machine without shutting it down.
This functionality is commonly used during operating system installations or software updates. The change- media command supports both live and persistent changes depending on the options used.
Therefore, the correct and documented answer ischange-media.

Question #4

In the command vzctl ____________ 105 /usr/bin/apt-get install wget, which subcommand of vzctl is missing in order to install wget in the OpenVZ container 105?

Answer:

exec
Explanation:
In OpenVZ virtualization, thevzctlcommand is used to manage containers. According to OpenVZ documentation, theexecsubcommand is required to execute a commandinside a running container.
The correct command syntax is:
vzctl exec 105 /usr/bin/apt-get install wget
The exec subcommand runs the specified command in the context of the container identified by its container ID (CTID), in this case105. Without exec, the command would not be executed inside the container environment.
Therefore, the missing and correct subcommand isexec.

Question #5

Which of the following commands lists all differences between the disk images vm1-snap.img and vm1.img?

  • A. virt-cp-in -a vm1-snap.img -A vm1.img
  • B. virt-delta -a vm1-snap.img -A vm1.img
  • C. virt-history -a vm1-snap.img -A vm1.img
  • D. virt-cmp -a vm1-snap.img -A vm1.img
  • E. virt-diff -a vm1-snap.img -A vm1.img
