Routing Protocols and Concepts, CCNA Exploration Labs and Study Guide, 2/e
暫譯: 路由協議與概念：CCNA 探索實驗室與學習指南（第二版）

Description

Routing Protocols and Concepts, CCNA Exploration Labs and Study Guide is designed to support your learning routing protocols and concepts in Version 4 of the Cisco Networking Academy CCNA® Exploration curriculum. Each chapter contains a Study Guide section and a Labs and Activities section.

 

Study Guide

The dozens of exercises in this book help you learn the concepts and configurations crucial to your success as a CCNA exam candidate. Each chapter is slightly different and includes multiple-choice, fill-in-the-blank, and open-ended questions designed to help you:

• Review vocabulary
• Strengthen troubleshooting skills
• Boost configuration skills
• Reinforce concepts
• Research topics

 

Packet Tracer Activities: This icon identifies exercises interspersed throughout the Study Guide section where you can practice or visualize a specific task using Packet Tracer, a powerful network simulation program developed by Cisco.

 

Labs and Activities: The Labs and Activities sections begins with a Command Reference table and includes all the online curriculum labs to ensure that you have mastered the practical skills needed to succeed in this course.

 

Hands-On Labs: This icon identifies the hands-on labs created for each chapter. Work through all the Basic, Challenge, and Troubleshooting labs as provided to gain a deep understanding of CCNA knowledge and skills to ultimately succeed on the CCNA Certification Exam.

 

Packet Tracer Companion: This icon identifies the companion activities that correspond to each hands-on lab. You use Packet Tracer to complete a simulation of the hands-on lab.

 

Packet Tracer Skills Integration Challenge: Each chapter concludes with a culminating activity called the Packet

Tracer Skills Integration Challenge. These challenging activities require you to pull together several skills learned from the chapter, as well as previous chapters and courses, to successfully complete one comprehensive exercise.

 

Allan Johnson works full time developing curriculum for Cisco Networking Academy. Allan also is a part-time instructor at Del Mar College in Corpus Christi, Texas.

本書中的數十個練習幫助您學習對於成功通過 CCNA 考試至關重要的概念和配置。每一章略有不同，包含多選題、填空題和開放式問題，旨在幫助您：
- 複習詞彙
- 加強故障排除技能
- 提升配置技能
- 鞏固概念
- 研究主題

Packet Tracer 活動：此圖示標識了學習指南部分中穿插的練習，您可以使用 Packet Tracer 這個由 Cisco 開發的強大網路模擬程式來練習或可視化特定任務。

實驗室與活動：實驗室與活動部分以命令參考表開始，並包含所有在線課程實驗室，以確保您掌握成功完成本課程所需的實用技能。

動手實驗室：此圖示標識了為每一章創建的動手實驗室。按照提供的所有基本、挑戰和故障排除實驗室進行操作，以深入理解 CCNA 知識和技能，最終成功通過 CCNA 認證考試。

Packet Tracer 伴隨活動：此圖示標識了與每個動手實驗室相對應的伴隨活動。您使用 Packet Tracer 完成動手實驗室的模擬。

Packet Tracer 技能整合挑戰：每一章以一個名為 Packet Tracer 技能整合挑戰的綜合活動結束。這些具有挑戰性的活動要求您整合從本章以及之前的章節和課程中學到的多項技能，以成功完成一個綜合性練習。
