Book Abstract

定发生的是什么问题（如用户的设备不响应或不可达）。
运营人员提供第2层支持，他们负责解决帮助台转来的问题以及主动监视网络。
在工程师团队不在时，运营人员还需代表他们实施变更。
网络工程师团队可能提供第3层支持，但他们的工作重点通常是设计工作，这包括规划新配置，以支持新场点和新功能。
网络设计师不像运营人员和工程师团队那样经常登录网络设备，其工作重点是从内部和外部客户那里收集需求，并根据这些需求确定网络设计方案。他们还可能进行概念验证测试，但将部署设计方案的具体工作留给网络工程师团队去完成。
当然，多少人承担上述每种角色随企业而异。在小型企业，可能只需要一名网络设计师和一名网络工程师，还需要两三名网络运营人员，这可能无法实现24×7覆盖，但也差不多。根据企业的规模，帮助台需要的人员可能最多，对所有这些人的技能要求都相同。
在最大的公司中，网络人员可能由多个部门的网络工程师组成。
无论如何，都需要有人承担上述每种职责，以提供妥善的支持。作为网络专业人员或网络工程师，您的职责是独立地工作，并向IT专业人员提供规划、文档和验证。

Introduction

认证概述以及如何获得成功
多年以来，职业认证已经成为计算业界的一个重要组成部分，并将变得更加重要。
这些认证的出现有多种原因，但最常被引述的原因是可信性。所有其他的原因都类似，那就是我们通常会认为，通过认证的雇员／顾问／求职者要比那些没有通过认证的人更有价值。
目标和方法
本书最重要的目标是帮助读者通过Cisco CCNP SWITCH考试（642-813）。事实上，如果不是这样，本书的书名将误导读者。然而，本书用于帮助通过SWITCH考试的方法也能让读者明白如何更好地完成工作任务。虽然本书及配套光盘包含很多备考任务和模拟考题，但它们并非要帮助读者记住尽可能多的考题和答案。
本书采用的方法是，帮助读者了解自己需要进一步复习的考试主题，完全理解和记住这些主题的细节，并证明自己掌握了关于这些主题的知识。所以，本书并不是通过记忆来帮助读者通过认证考试，而是让读者通过真正地学习和理解相关主题来达到目的。SWITCH考试是CCNP交换和路由认证的一项基础主题，其中包含的知识对于确认自己是否是娴熟的路由选择和交换工程师或专家非常重要。如果不能真正帮助读者学习知识，就是误人子弟。因此，本书通过下述方法帮助读者通过SWITCH考试：
涵盖所有的考试主题并帮助读者找出还未掌握的考试主题；
提供解释和信息以填补读者知识的空缺；
通过备考任务以及包含示意图和配置的网络示例加深记忆和提高推断答案的能力；通过配套光盘中的模拟题让读者进行练习和熟悉考试过程。
