질문 # 20
Which of the following tasks are part of a hypervisor's responsibility? (Choose two.)

A. Manage authentication to network services running inside a virtual machine.
B. Provide host-wide unique PIDs to the processes running inside the virtual machines in order to ease inter-process communication between virtual machines.
C. Create filesystems during the installation of new virtual machine quest operating systems.
D. Isolate the virtual machines and prevent unauthorized access to resources of other virtual machines.
E. Map the resources of virtual machines to the resources of the host system.

정답：D,E

질문 # 21
Which of the following commands deletes all volumes which are not associated with a container?

A. docker volume garbage-collect
B. docker volume orphan -d
C. docker volume prune
D. docker volume cleanup
E. docker volume vacuum

정답：C

설명：
Explanation
The command that deletes all volumes which are not associated with a container is docker volume prune. This command removes all unused local volumes, which are those that are not referenced by any containers. By default, it only removes anonymous volumes, which are those that are not given a specific name when they are created. To remove both unused anonymous and named volumes, the --all or -a flag can be added to the command. The command will prompt for confirmation before deleting the volumes, unless the --force or -f flag is used to bypass the prompt. The command will also show the total reclaimed space after deleting the volumes12.
The other commands listed in the question are not valid or do not have the same functionality as docker volume prune. They are either made up, misspelled, or have a different purpose. These commands are:
* docker volume cleanup: This command does not exist in Docker. There is no cleanup subcommand for docker volume.
* docker volume orphan -d: This command does not exist in Docker. There is no orphan subcommand for docker volume, and the -d flag is not a valid option for any docker volume command.
* docker volume vacuum: This command does not exist in Docker. There is no vacuum subcommand for docker volume.
* docker volume garbage-collect: This command does not exist in Docker. There is no garbage-collect subcommand for docker volume.

* docker volume prune | Docker Docs

질문 # 22
Which disk image formats are commonly used in Linux-based virtualization environments? (Select all that apply)

A. RAW
B. QCOW2
C. VMDK
D. VHD

정답：A,B,C,D

설명：
Linux-based virtualization environments support a wide range of disk image formats to ensure compatibility with multiple hypervisors and cloud platforms. According to virtualization documentation,RAW, VMDK, QCOW2, and VHDare all commonly used formats.
RAWimages are simple, unstructured disk files that offer maximum performance due to minimal overhead.
QCOW2(QEMU Copy-On-Write version 2) is the most widely used format in KVM environments because it supports advanced features such as snapshots, thin provisioning, compression, and encryption.VMDKis the native disk format for VMware products but is frequently used in Linux environments for interoperability and migration purposes.VHDis commonly associated with Microsoft Hyper-V but is also supported by QEMU and cloud platforms.
Virtualization notes emphasize that modern Linux virtualization tools like QEMU and libvirt are designed to work across multiple disk formats. This flexibility enables administrators to migrate workloads between different hypervisors and cloud providers without rebuilding virtual machines.
Therefore, all listed disk image formats are valid and commonly supported in Linux-based virtualization environments.

질문 # 23
Which of the following statements about the commandlxc-checkpointis correct?

A. It creates a clone of a container.
B. It writes the status of the container to a file.
C. It only works on stopped containers.
D. It doubles the memory consumption of the container.
E. It creates a container image based on an existing container.

정답：B

질문 # 24
What types of cloud-init data sources can be used to configure cloud instances? (Select all that apply)

A. Cloud-based configuration management tools
B. Metadata service
C. User data scripts
D. QR codes

정답：B,C

설명：
Cloud-init is a widely used initialization system for cloud instances, allowing configuration at first boot.
According to cloud-init documentation, the two primary data sources used to configure instances aremetadata servicesanduser data scripts.
Ametadata serviceprovides instance-specific information such as hostname, instance ID, networking details, and SSH keys.User data scriptsallow administrators to supply custom configuration instructions, commonly written as shell scripts or cloud-config YAML.
Cloud-based configuration management tools like Ansible or Puppet are not cloud-init data sources; instead, cloud-init may install or trigger them.QR codesare not supported data sources in cloud-init.
Virtualization and cloud documentation clearly identifies metadata and user data as the supported configuration mechanisms. Therefore, the correct answers areB and D.
