Red Hat Certified Technician & Engineer: Training Guide and Administrator's Reference

I bought this book to complement the Jang text in preparation for the RHCE. Strictly as a study guide for the RHCE, I would have some concerns. It is somewhat light on explaining theories and concepts before jumping into examples and steps to complete RHCT RHCE tasks. In addition, there are a few areas i.e., setting up an LDAP client where the task includes some unnecessary steps. I got the impression that these extra steps were probably good practice or driven by internal policy, but I rather thought that should have been explained.
