In Ansible, a playbook is a YAML file that defines tasks, configurations, and automation workflows. It is commonly used to deploy applications, configure systems, and manage infrastructure on Linux systems.

OpenSCAP is a framework that automates security compliance checking and vulnerability management by using standardized security content (SCAP). It helps administrators enforce policies and detect vulnerabilities.

CPU architecture must match because live migration requires CPU compatibility to continue running the virtual machine without errors.Disk storage path must match so the migrated VM can access its virtual disks seamlessly on the destination host.

The .bkp file here is a cpio archive, not a tar or zip. The correct way to extract it is by changing into the target directory (/var/www/html/) and using cpio -idv < /home/dev/web.bkp. The pushd and popd commands ensure the administrator returns to the original directory afterward.

The docker run -it command both creates a new container from the specified image and attaches to it interactively, which is exactly what the administrator needs.

The /proc filesystem is a virtual filesystem that provides process and kernel information. It is non-persistent and volatile, meaning its contents exist only in memory and are regenerated at each system boot.

Using ${num} ensures correct variable expansion, especially when variables are adjacent to other characters or hyphens. This prevents ambiguity and guarantees $num is properly expanded within the string.

Log aggregation is the process of collecting and consolidating logs from multiple sources into a single location, making it easier to analyze and manage system events.

The usermod -aG command appends (-a) the user to a supplementary group (-G) without changing their primary group. This is the correct way to add a user to the docker group.

The git reset command reverts changes in the local repository to a previous commit, effectively discarding the problematic modifications and restoring the application to a working state.
