○

Reference / correct answer:

If a user jules is added with the user add jules command, a group called jules is also added. but no other user may be a member of that group.

A directory owned by a group to which several users belong, and which has the setgid fa turned on, has shared write access to all members of the group.

The User private Group scheme is enabled by default in Oracle Linux.

DF (not A): By default, Oracle Linux implements the user private group (UPG) scheme where adding a user account also creates a corresponding UPG with the same name as the user, and of which the user is the only member.

E: When setgid permission is applied to a directory, files that were created in this directory belong to the group to which the directory belongs, not the group to which the creating process belongs. Any user who has write and execute permissions in the directory can create a file there. However, the file belongs to the group that owns the directory, not to the user's group ownership.
