This book will aid readers who are preparing for the new CompTIA 2006 certification in A+ or the current Network+ and Security+ certifications. It reviews all of the topics needed to master each exam in a concise format, covering each exam in about 150 pages. Because the objectives for the three A+ exams are redundant, the book covers them in one section. Each exam is covered in three parts, with an exam overview, a study guide, and practice questions. Tables, screenshots, and study notes are included. The exams covered include: A+ Essentials for A+2006 certification; Exam 220-602 for the A+ IT Technician specialization; Exam 220-603 for the A+ Remote Support Technician specialization; Exam 220-604 for the A+ IT Depot specialization; Exam N10-003 for Network+ certification; and Exam SYO-101 for Security+ certification. Bhardwaj is an independent technical trainer.
