XK0-006 Practice Question: An administrator is configuring a chroot jail for…
An administrator is configuring a chroot jail for an SFTP user. Which directive in /etc/ssh/sshd_config is used for this purpose?
⚠ Common exam trap
A common mix-up: candidates confuse the directive that enables SFTP (Subsystem or ForceCommand) with the directive that actually creates the chroot jail (ChrootDirectory), leading them to select a functional but incomplete option.

Correct answer & explanation
✓
ChrootDirectory /home/%u
The ChrootDirectory directive in /etc/ssh/sshd_config specifies the path to the directory that will be used as a chroot jail for the user. When set to /home/%u, %u is replaced by the username, confining the SFTP user to their home directory. This is the standard way to restrict an SFTP user's file system access to a specific directory tree.
