LFCS Question #329: Real Exam Question with Answer & Explanation

Question

Which command CANNOT be used to mount a shared filesystem in your Linux environment?

Options

• Amount.cifs //server/share /mnt -o user=user
• Bmount -t cifs //server/share /mnt -o user=user
• Cmount -t smbfs //server/share /mnt -o username=user
• Dsmbmount //server/share /mnt -o username=user
• Ecifsmount //server/share /mnt -o username=user

Explanation

The cifsmount command is not a standard Linux utility for mounting shared filesystems; other commands like mount.cifs, mount -t cifs, mount -t smbfs, and smbmount are valid.

Common mistakes.

• A. The mount.cifs command is a dedicated helper utility for mounting CIFS (SMB) shares and is part of the cifs-utils package.
• B. The mount -t cifs command uses the generic mount command with the -t option to specify the CIFS filesystem type, which is a standard way to mount CIFS shares.
• C. The mount -t smbfs command uses the generic mount command with the -t option to specify the smbfs filesystem type, which is an older but still valid way (often an alias to cifs) to mount SMB/CIFS shares.
• D. The smbmount command was an older, dedicated utility for mounting SMB shares and is still present or aliased in some systems for compatibility, making it a valid although potentially deprecated option.
