문제2
What is the same of the global configuration file for the xl tool stack?
What is the same of the global configuration file for the xl tool stack?
정답:
/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.

What is the default path to the Docker daemon configuration file on Linux? (Specify the full name of the file, Including path.)
FILL BLANK
What is the default path to the Docker daemon configuration file on Linux? (Specify the full name of the file, Including path.)
정답:
/etc/docker/daemon.json
Explanation:
The default path to the Docker daemon configuration file on Linux is /etc/docker/daemon.json. This file is a JSON file that contains the settings and options for the Docker daemon, which is the service that runs on the host operating system and manages the containers, images, networks, and other Docker resources. The /etc
/docker/daemon.json file does not exist by default, but it can be created by the user to customize the Docker daemon behavior. The file can also be specified by using the --config-file flag when starting the Docker daemon. The file must be a valid JSON object and follow the syntax and structure of the dockerd reference docs12. References:
* Docker daemon configuration file - Medium3
* Docker daemon configuration overview | Docker Docs4
* docker daemon | Docker Docs5
