질문 # 25
Which of the following statements is true regarding the following output ofxl list:

정답：E

설명：
Explanation
The output of xl list shows the state of the domains. The domain with ID 6, Ubuntu, has a state of "b-". This means that the domain is blocked, which means it is idle or waiting for I/O.

질문 # 26
Which operating systems are compatible with cloud-init? (Select all that apply)

정답：B

설명：
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).


질문 # 27
What is the purpose of the commandvagrant init?

정답：D

설명：
The command vagrant init is used to initialize the current directory to be a Vagrant environment by creating an initial Vagrantfile if one does not already exist1. The Vagrantfile contains the configuration settings for the Vagrant box, such as the box name, box URL, network settings, synced folders, provisioners, etc. The command vagrant init does not execute any provisioning tool, start any box, install Vagrant on a Linux host, or download any box. Those actions are performed by other Vagrant commands, such as vagrant provision, vagrant up, vagrant install, and vagrant box add, respectively. References:

질문 # 28
Which container orchestration platform is often associated with automated scaling and load balancing?

정답：B

설명：
Kubernetesis the container orchestration platform most strongly associated withautomated scaling and load balancing. According to container orchestration documentation, Kubernetes provides built-in features such as Horizontal Pod Autoscaling, service-based load balancing, self-healing, and declarative deployment models.
Docker Compose and LXC are not orchestration platforms at scale, and while Amazon ECS supports scaling, Kubernetes is the industry-standard platform most commonly referenced for these capabilities.
Therefore, the correct answer isB.


질문 # 29
When using Packer to create machine images, what are some common sources for base images? (Select all that apply)

정답：A,D

설명：
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 imagesas the starting point for image creation. The most common sources includeofficial operating system imagesprovided by vendors such as Red Hat, Ubuntu, or cloud service providers, andcustom 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 supportscustom organizational imagesandofficial operating system imagesas the correct and recommended base sources for Packer image creation.
