In addition, new features include "How To" quick references for step-by-step tasks; real-world examples and all-new illustrations; concise explanations with a focus on word usage and sentence structure for improved readability; and correlations to the CCNA exam in Chapter Objectives, Check Your Understanding questions, and new Challenge Activities.
