LPIC-3 Exam 300 (Mixed Environments) — Question 5

After adding a remote CIFS share to /etc/fstab, the share is mounted to the correct location in the file system. There, all files belong to the user and group root and are not readable or writable by any other users on the system. What should be done in order to permit distinct local user access to the mounted files?

Answer options

• A. The option root squash = yes should be added to the share in the Samba server's smb.conf to allow full access by the client.
• B. The mount.cifs options uid, gid, file_mode and dir_mode should be used to specify the ownership and permissions of the mount.
• C. The user should be added to the local user group smbusers, as mount.cifs by default restricts access to all CIFS mounts to member of this group in addition to the root account.
• D. The mount.cifs command should always be executed by user who will use the mount afterwards. The user should be granted the required permission in / etc/sudoers.

Correct answer: C

Explanation

The correct answer is C because adding the user to the smbusers group allows them to access the CIFS mount, which is restricted by default to root and members of this group. Options A and B do not address user access directly, and option D misleads by suggesting that the mount command must be executed by the user, which does not resolve the fundamental access restriction.
