What is the correct command to install the VDO driver for compression and deduplication on a storage device?

The correct command to install the VDO driver for compression and deduplication on a storage device is accomplished using the yum install command. This command is specifically designed for installing packages on systems that utilize the YUM (Yellowdog Updater, Modified) package manager, which is prevalent in Red Hat-based distributions.

When you use yum install vdo kmod-kvdo, it directs the package manager to locate and install the 'vdo' package, as well as the 'kmod-kvdo' kernel module. These components are essential for enabling VDO (Virtual Data Optimizer), which provides features like compression and deduplication that can significantly optimize storage use in environments where data is stored.

The structure of the command is also important: 'install' is the appropriate verb for adding new software packages, whereas the other options either incorrectly use verbs like 'get', 'add', or 'update', which do not align with the proper syntax or functionality for package installation in this context. Using the correct command ensures that the necessary components are downloaded from the appropriate repositories and installed on the system, setting up the environment appropriately for storage optimization tasks.
