Lpi LPIC-3 Exam 305: Virtualization and Containerization Sample Questions (Q45-Q50):

NEW QUESTION # 45
What is the purpose of capabilities in the context of container virtualization?

Answer: E


NEW QUESTION # 46
What is the primary benefit of using Packer for creating machine images?

Answer: D

Explanation:
Packer is an image automation tool whose primary benefit is ensuring consistency across environments.
According to virtualization and DevOps documentation, Packer allows administrators to create identical machine images for development, testing, and production from a single configuration.
By using the same base image and build process, Packer eliminates configuration drift and ensures that environments behave consistently. This significantly reduces deployment issues caused by environmental differences and supports Infrastructure as Code best practices.
Packer does not monitor virtual machines or directly speed up application development. While it can indirectly simplify deployments, its main advantage is image consistency and repeatability.
Therefore, the correct answer is B.


NEW QUESTION # 47
Which operating systems are compatible with cloud-init? (Select all that apply)

Answer: C

Explanation:
Cloud-initis an initialization and configuration system designed primarily forLinux-based cloud instances.
According to official cloud-init documentation, it is supported on a wide range of Linux distributions, including Ubuntu, Red Hat Enterprise Linux, CentOS, Debian, and SUSE.
Windows systems use a separate project calledCloudbase-Init, which is not cloud-init itself. macOS and Android do not support cloud-init.
Therefore, the correct answer isC (Linux).


NEW QUESTION # 48
Which of the following values would be valid in the FROM statement in aDockerfile?

Answer: B


NEW QUESTION # 49
Which of the following statements are true regarding resource management for full virtualization? (Choose two.)

Answer: C,D

Explanation:
Resource management for full virtualization is the process of allocating and controlling the physical resources of the host system to the virtual machines running on it. The hypervisor is the software layer that performs this task, by providing each virtual machine with a virtual hardware of a defined capacity that limits the resources of the virtual machine. For example, the hypervisor can specify how many virtual CPUs, how much memory, and how much disk space each virtual machine can use. The hypervisor can also enforce resource isolation and prioritization among the virtual machines, to ensure that they do not interfere with each other or consume more resources than they are allowed to. The hypervisor cannot provide fine-grained limits to internal elements of the guest operating system, such as the number of processes, because the hypervisor does not have access to the internal state of the guest operating system. The guest operating system is responsible for managing its own resources within the virtual hardware provided by the hypervisor. For example, the guest operating system can create an arbitrary amount of network sockets, as long as it does not exceed the network bandwidth allocated by the hypervisor. Full virtualization can pose limits to virtual machines, and does not always assign the host system's resources in a first-come-first-serve manner. The hypervisor can use various resource management techniques, such as reservation, limit, share, weight, and quota, to allocate and control the resources of the virtual machines. The hypervisor can also use resource scheduling algorithms, such as round-robin, fair-share, or priority-based, to distribute the resources among the virtual machines according to their needs and preferences. All processes created within the virtual machines are not transparently and equally scheduled in the host system for CPU and I/O usage. The hypervisor can use different scheduling policies, such as proportional-share, co-scheduling, or gang scheduling, to schedule the virtual CPUs of the virtual machines on the physical CPUs of the host system. The hypervisor can also use different I/O scheduling algorithms, such as deadline, anticipatory, or completely fair queuing, to schedule the I/O requests of the virtual machines on the physical I/O devices of the host system. The hypervisor can also use different resource accounting and monitoring mechanisms, such as cgroups, perf, or sar, to measure and report the resource consumption and performance of the virtual machines.
