질문 # 54
Which of the following values would be valid in the FROM statement in aDockerfile?

정답：C

설명：
The FROM statement in a Dockerfile specifies the base image from which the subsequent instructions are executed1. The value of the FROM statement can be either an image name, an image name with a tag, or an image ID1. The image name can be either a repository name or a repository name with a registry prefix2. For example, ubuntu is a repository name, and docker.io/ubuntu is a repository name with a registry prefix2. The tag is an optional identifier that can be used to specify a particular version or variant of an image1. For example, ubuntu:focal refers to the image with the focal tag in the ubuntu repository2. The image ID is a unique identifier that is automatically generated when an image is built or pulled1. For example, sha256:
9b0dafaadb1cd1d14e4db51bd0f4c0d56b6b551b2982b2b7c637ca143ad605d2 is an image ID3.
Therefore, the only valid value in the FROM statement among the given options is ubuntu:focal, which is an image name with a tag. The other options are invalid because:
* docker://ubuntu:focal is not a valid image name format. The docker:// prefix is used to specify a transport protocol, not a registry prefix4.
* registry:ubuntu:focal is not a valid image name format. The registry prefix should be a valid hostname or IP address, not a generic term2.
* file:/tmp/ubuntu/Dockerfile is not a valid image name format. The file: prefix is used to specify a local file path, not an image name5.
* http://docker.example.com/images/ubuntu-focal.iso
is not a valid image name format.
The
http:// prefix is used to specify a web URL, not an image name
5.

질문 # 55
Which of the following resources can be limited by libvirt for a KVM domain? (Choose two.)

정답：B,C


질문 # 56
How do containers share the host OS kernel?

정답：C

설명：
Containers operate bysharing the host operating system's kernelwhile running inisolated user spaces.
According to containerization documentation, Linux kernel features such asnamespaces and cgroupsprovide process isolation, resource control, and security boundaries between containers.
Each container has its own filesystem, process tree, and network stack, but all containers rely on the same underlying kernel. This design makes containers lightweight and efficient compared to virtual machines, which require separate guest kernels.
Options A and D are incorrect because containers do use the host kernel. Option C is incomplete because it does not mention isolation. Therefore, the correct answer isB.


질문 # 57
What is the same of the global configuration file for the xl tool stack?

정답：

설명：
/etc/xen/xl.conf
Explanation:
Thexl toolstackis the modern command-line management interface used for administering theXen hypervisor
, replacing the older xm toolstack. According to official Xen virtualization documentation, theglobal configuration filefor the xl toolstack is/etc/xen/xl.conf.
This configuration file definesdefault behaviors and policiesfor the xl management commands. It allows administrators to configure global settings such as default CPU scheduling behavior, memory handling, device model settings, and other operational parameters that affect how virtual machines (domains) are managed on a Xen host. These settings apply system-wide and influence the behavior of all xl commands unless overridden by per-domain configuration files.
The file /etc/xen/xl.conf is read by the xl toolstack at runtime and is part of the standard Xen configuration directory structure. Individual virtual machine definitions are typically stored as separate configuration files in
/etc/xen/, but xl.conf serves as thecentral, global configuration reference.
Virtualization notes emphasize that proper configuration of xl.conf is important for performance tuning, stability, and compliance in Xen-based environments. While many default installations function correctly without modifying this file, enterprise deployments often customize it to align with workload requirements and hardware capabilities.
Therefore, the correct and documented global configuration file for the xl toolstack is/etc/xen/xl.conf.


질문 # 58
What does IaaS stand for?

정답：C

설명：
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.
