You need to look up a Red Hat Enterprise Linux (RHEL) system in Host Management.

Red Hat Enterprise Linux is an operating system distribution and version family, so the most precise Host Management filter is OS version . Platform would generally distinguish broad operating system families such as Windows, macOS, or Linux, but it would not narrow results specifically to RHEL. Type identifies host form factor or role, such as desktop, server, or domain controller. OU refers to Active Directory organizational unit membership, which applies to directory-joined assets rather than Linux distribution identity. The course guide’s Host Management and dynamic grouping filter list identifies OS Version as the field used for the installed operating system version. Therefore, to locate RHEL systems, OS version is the most appropriate filter.
