The best way to repair a failure is to prevent it from happening in the first place. It is a well-known fact of life that failures occur at the most inopportune times. A little preventive maintenance can minimize the impact by either catching and repairing the failure before it happens, or preventing it altogether. Likewise, safety issues are prevalently featured throughout the A+ certification exam. In fact, one objective (10 percent) of the core exam is devoted to this subject. Because of their importance, this tutorial focuses on reviewing and expanding upon these issues.
