Which command allows users to check how a file’s security context is currently set?

The command that allows users to check how a file's security context is currently set is represented by the option that involves "ls -Z". This command lists the contents of a directory along with their SELinux security contexts. By using "ls -Z", users can see the security label attached to each file and directory, which provides crucial information about the file's security context, including its user, role, type, and sensitivity level.

The other commands listed serve different purposes. For instance, “getsebool” is used to query the current status of SELinux boolean settings, which control various security-related aspects of how SELinux behaves but do not provide information about individual file contexts. "restorecon" is a command utilized to restore the default SELinux context of a file based on the policy, serving as a corrective measure rather than a diagnostic one. “setsebool”, on the other hand, modifies the value of a specified SELinux boolean and does not display file security contexts.

Thus, "ls -Z" is specifically designed to display the current security context of files, making it the correct choice for this question.
