Free LPI 305-300 Exam Actual Questions

Note: Premium Questions for 305-300 were last updated On Mar. 15, 2026 (see below)

Question #1

When using Packer to create machine images, what are some common sources for base images? (Select all that apply)

Reveal Solution Hide Solution
Correct Answer: C, D

Packer is an image automation tool used to create identical machine images for multiple platforms from a single configuration. According to virtualization and containerization documentation, Packer typically uses trusted and standardized base images as the starting point for image creation. The most common sources include official operating system images provided by vendors such as Red Hat, Ubuntu, or cloud service providers, and custom images created internally by an organization.

Using official images ensures that the base system is secure, properly maintained, and compliant with vendor standards. Organizations often build custom base images to enforce internal security policies, hardening standards, and preinstalled software, which Packer then extends into environment-specific images.

Physical servers are not considered common or practical base sources for Packer, as Packer operates on machine image artifacts rather than cloning live hardware systems. Images from untrusted sources are explicitly discouraged in virtualization documentation due to security and compliance risks.

Therefore, documentation clearly supports custom organizational images and official operating system images as the correct and recommended base sources for Packer image creation.


Question #2

Which of the following KVM parameters is identical to the KVM parameter -hdb file.img?

Reveal Solution Hide Solution
Correct Answer: D

In QEMU/KVM, the legacy parameter -hdb file.img attaches a disk image as the primary IDE slave device. According to QEMU documentation, this corresponds to an IDE device with index 1, media type disk, and interface IDE.

The modern equivalent using the -drive syntax is:

-drive file=file.img,index=1,media=disk,if=ide

Option D matches this mapping precisely. The other options use invalid or unsupported parameter combinations and do not correctly represent the IDE device mapping.

Therefore, the correct answer is D.


Question #3

What command is used to run a process in a new Linux namespace? (Specify ONLY the command without any path or parameters.)

Reveal Solution Hide Solution
Correct Answer: A

Question #4

What is the default path to the Docker daemon configuration file on Linux? (Specify the full name of the file, Including path.)

Reveal Solution Hide Solution
Correct Answer: A

Question #5

What command is used to run a process in a new Linux namespace? (Specify ONLY the command without any path or parameters.)

Correct Answer: A
