Lpi LPIC-3 Exam 305: Virtualization and Containerization Sample Questions (Q24-Q29):

NEW QUESTION # 24
Which of the following are benefits of virtualization?

A. Simplified backup and recovery
B. Reduced software compatibility issues
C. Improved hardware utilization
D. Increased security

Answer: A,C,D

Explanation:
Virtualization provides several well-documented benefits in modern IT environments. One major advantage is improved hardware utilization(A), as multiple virtual machines can run on a single physical system, maximizing resource usage. Virtualization also enhancessecurity(C) through isolation between workloads, limiting the impact of failures or security breaches.
Another key benefit issimplified backup and recovery(D). Virtual machines are encapsulated into files, making it easier to snapshot, back up, clone, and restore entire systems. This significantly improves disaster recovery and testing workflows.
Option B is not universally true. While virtualization can help standardize environments, it does not inherently reduce software compatibility issues; in some cases, it may even introduce additional layers of complexity.
Virtualization documentation consistently highlightshardware efficiency, security isolation, and operational flexibilityas core benefits, makingA, C, and Dthe correct answers.

NEW QUESTION # 25
How does Packer interact with system images?

A. Packer downloads and extracts an image in order to make changes to the image's file system, repack the modified image and upload it again.
B. Packer installs a client within the image which has to be run periodically via cron in order to retrieve the latest template from the Packer server and apply it locally.
C. Packer periodically connects through the network to the Packer daemons of all running Packer images in order to re-apply the whole template to the running instance.
D. Packer has to be installed within the target image and is executed during the image's first boot in order to execute preparation tasks.
E. Packer creates an instance based on a source image, prepares the instance through a network connection and bundles the resulting instance as a new system image.

Answer: E

Explanation:
Explanation
Packer is a tool that automates the creation of identical machine images for multiple platforms from a single source configuration. Packer works by creating an instance based on a source image, which is a pre-existing image that serves as a starting point. Packer then connects to the instance through a network connection, such as SSH or WinRM, and runs various commands and scripts to install and configure software within the instance. Packer then shuts down the instance and creates a new system image from it, which can be used to launch new instances. Packer supports many platforms, such as AWS, Azure, VMware, Docker, and others.
Packer does not install any software or run any daemon within the target image, nor does it periodically connect to the running instances to re-apply the template. Packer also does not modify the source image directly, but creates a new image from the modified instance. References:

NEW QUESTION # 26
Which of the following values are valid in the type attribute of a<domain>element in a libvirt domain definition? (Choose two.)

A. Ixc
B. proc
C. namespace
D. kvm
E. cgroup

Answer: A,D

Explanation:
Explanation
The type attribute of a <domain> element in a libvirt domain definition specifies the hypervisor used for running the domain. The allowed values are driver specific, but include "xen", "kvm", "hvf" (since 8.1.0 and QEMU 2.12), "qemu" and "lxc"1. Therefore, the valid values among the options are C. kvm and E. lxc. KVM stands for Kernel-based Virtual Machine, which is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V)2. LXC stands for Linux Containers, which is an operating system-level virtualization method for running multiple isolated Linux systems (containers) on a single control host3. The other options are not valid values for the type attribute, asthey are either not hypervisors or not supported by libvirt. References:http://libvirt.org/formatdomain.html

NEW QUESTION # 27
What does IaaS stand for?

A. Infrastructure as a Service
B. Integration as a Service
C. Intelligence as a Service
D. Instances as a Service
E. Information as a Service

Answer: A

Explanation:
Explanation
IaaS is a type of cloud computing service that offers essential compute, storage, and networking resources on demand, on a pay-as-you-go basis. IaaS is one of the four types of cloud services, along with software as a service (SaaS), platform as a service (PaaS), and serverless12. IaaS eliminates the need for enterprises to procure, configure, or manage infrastructure themselves, and they only pay for what they use23. Some examples of IaaS providers are Microsoft Azure, Google Cloud, and Amazon Web Services.

What is the purpose of a .dockerignore file?

A. It must be placed in the top level directory of volumes that Docker should never attach automatically to a container
B. It specifies which parts of a Dockerfile should be ignored when building a Docker image.
C. It lists files existing in a Docker image which should be excluded when building a derivative image.
D. It specifies files that Docker does not submit to the Docker daemon when building a Docker image
E. It exists in the root file system of containers that should ignore volumes and ports provided by Docker.

Answer: D
