3g路由器 交换机模拟器和路由器的不同之处
思科认证一直被认为是IT业界一个金字招牌,目前路由器与交换机的应用非常广泛,今天我们主要介绍路由器与交换机的综合比较。
一、什么的模拟器
模拟器是使用软件来营造出一种虚拟的实验环境,其中包含了实验所需要的路由器与交换机连接方式,点击进入相关的设备即可进行操作,虽然模拟器个个价格不菲,但一来它是安装在电脑上,不必为经常跑实验室浪费时间而担忧,二来它以后还可以继续发挥作用,对学习超过教材范围的知识,只要模拟器能够支持,都可以学,让你体会到物超所值的感觉。
二、模拟器的分类
大家所接触的模拟器或者说算得上是模拟器的只有五种,它们分别是:RouterSim4.0、Sybex Virtual Lab、思科网络学院Flah Lab、CIM、Boson Netsim5.31。
三、思科职业证书
思科的这种职业证书的考试完全不像国内的传统考试,除了自适应之外,还有很多的操作题目,即给一个模拟的环境与配置条件,要求你在模拟界面进行正确的命令行操作,这一点怕是很多国内考生最头痛的地方,因为对于他们来说,没有太多这种真实的路由器与交换机的环境进行操作,自然动手能力要差很多,然而思科的认证对于考生的动手能力要求很高,这也是国际职业资格认证的一种趋势,因为对于这些证书对考生的要求就是:通过考试之后,就证明你有相当的技术水平与动手能力,而不是只有理论。从这一点上来说,如果能够拿到证书,就可以在工作中直接去做,而不必去花很长的时间去学习。
交换机模拟器和思科路由器都是经常用到的设备,熟练掌握也是网络工程师必须知道的技能。
