Three of the 55 questions in this pack

Question 1

What is the purpose of the command vagrant init?

  1. It executes a provisioning tool in a running box.
  2. It starts a Vagrant box.
  3. It creates a Vagrant configuration file.
  4. It installs Vagrant on a Linux host.
  5. It downloads a Vagrant box.
Show answer and explanation

Correct answer: C. It creates a Vagrant configuration file.

The vagrant init command creates a Vagrantfile, which is the configuration file that defines how a Vagrant environment should be set up. This file specifies the box to use, provider settings, networking, and provisioning instructions. It is the first step in setting up a new Vagrant project.

Why the other options are wrong

  • A. Provisioning is performed by vagrant provision, not vagrant init.
  • B. Starting a box is done with vagrant up, not vagrant init.
  • D. Vagrant is installed on the host system beforehand, not via vagrant init.
  • E. Downloading a box happens during vagrant up or with vagrant box add, not vagrant init.

Question 2

In order to use the option dom0_mem to limit the amount of memory assigned to the Xen Domain-0, where must this option be specified?

  1. In the bootloader configuration, when Xen is booted.
  2. In any of Xen’s global configuration files.
  3. In its .config file, when the Domain-0 kernel is built.
  4. In the configuration file /etc/xen/Domain-0.cfg, when Xen starts.
  5. In its Makefile, when Xen is built.
Show answer and explanation

Correct answer: A. In the bootloader configuration, when Xen is booted.

The dom0_mem parameter is a Xen hypervisor parameter that must be passed to the hypervisor at boot time. This is specified in the bootloader configuration (such as GRUB) so that the parameter is available when Xen starts and can allocate the specified amount of memory to Domain-0 before any domains are created.

Why the other options are wrong

  • B. Xen's global configuration files cannot pass parameters to the hypervisor at boot time.
  • C. The Domain-0 kernel's .config file controls kernel features, not hypervisor memory allocation.
  • D. Domain-0.cfg is used for Domain-0 virtual machine configuration, not hypervisor initialization parameters.
  • E. The Xen build Makefile controls compilation but not runtime hypervisor parameters.

Question 3

Which functionality is provided by Vagrant as well as by Docker? (Choose three.)

  1. Both can share directories from the host file system to a guest.
  2. Both start system images as containers instead of virtual machines by default.
  3. Both can download required base images.
  4. Both can apply changes to a base image.
  5. Both start system images as virtual machines instead of containers by default.
Show answer and explanation

Correct answer: A, C, D. Both can share directories from the host file system to a guest; Both can download required base images; Both can apply changes to a base image.

Vagrant and Docker both support sharing host directories with guests (A), downloading and using base images such as boxes or Docker images (C), and applying changes to base images through provisioners or Dockerfiles (D). However, they differ fundamentally in their default approach: Vagrant typically uses virtual machines while Docker uses containers, making options B and E incorrect as stated.

Why the other options are wrong

  • B. Docker starts containers by default, and Vagrant starts virtual machines by default; they are opposites.
  • E. This is contradictory to B and incorrect; Docker uses containers, not virtual machines by default.

What makes the 305-300 hard

This is the LPI exam where multiple choice is not the problem. The fill-in-the-blank questions are. 305-300 mixes multiple choice with fill in the blank, and on the blanks there is nothing to recognise and nothing to eliminate: the command, subcommand or option has to be typed and is either exactly right or worth zero. That means virsh subcommands, qemu-img flags, docker and lxc syntax, and cloud-init and Vagrant directive names all have to be in the fingers, not just familiar on sight.

The weighting is unusually top heavy: full virtualization is 25 points and container virtualization another 25, so those two topics make up 83% of the exam between them, while deployment and provisioning is only 10. Inside them, libvirt virtual machine management and Docker are the single heaviest objectives at 9 points each, then container concepts at 7 and virtualization theory at 6. Xen, QEMU, disk image management and orchestration platforms are worth 3 or 4 each, which is exactly why candidates over-study Xen and then run out of time on libvirt.

The exam is 60 questions in 90 minutes, and an active LPIC-2 is required to be awarded the LPIC-3 certification, though nothing stops candidates from sitting the 305 exam first. This pack has 55 practice questions mapped to the version 3.0 objectives.
