CCIE全称Cisco Certified Internetwork Expert,是美国Cisco公司于1993年开始推出的专家级认证考试。被全球公认为IT业最权威的认证,是全球Internetworking领域中最顶级的认证证书。目前,CCIE持有者占思科认证总人数还不足3%,全球网络从业者的1%不到(思科官方数据)。Cisco认证主要提供工程师在今日快速变动的网络环境中驾驭Cisco设备所需的专业知识。CCIE是Cisco(除了新推出的CCA以外)最高级技术能力的认证,位于Cisco金字塔认证体系中塔尖,也是IT界公认的最权威、最受尊重证书之一,2003年被评为全球十大IT认证榜首,具有IT终极认证的美称。取得CCIE证书除了整个行业的认同之外,CCIE也是你不断持有最新网络知识的指标;你将会在你的专业技术领域中成为一位最具竞争力的人
CCIE认证分active和inactive两种状态,Cisco公司为了让CCIE能够跟踪新技术,并保持CCIE的专家水平,从通过CCIE认证开始,每两年就要进行一次重认证,否则你虽然仍然拥有你的CCIE number,但是你的状态就从active变成inactive,相应的享有在cisco公司赋予的一些权利就没了。苛刻的认证规则使CCIE成为IT业界中含金量最高的证书之一,当然也成了最受尊重、最难取得的证书之一。
Cisco公司从1993年开设CCIE考试,截止到2010年4月30日,全球共有CCIE 20860名,中国大陆共有CCIE 3560名,其中超过半数在国外工作。
获得CCIE认证不仅证明你的技术达到专家水平,得到业界认可与肯定,更是一种荣誉的象征,一种自我价值的体现。获得CCIE认证成为每位网络技术人员的梦想。
Cisco公司为了让客户获得专家级技术支持,在其认证代理体系中规定金银牌认证代理商必须拥有一定数量的CCIE,这直接刺激了对CCIE的需求,在1999年期间,在中国大陆CCIE的年薪高达80万RMB。现在在系统集成项目中,许多业主提出承包商必须拥有CCIE认证专家,才有资格承接项目,由此可见CCIE专家在业界中的认可程度。
通过苛刻的CCIE认证后,您将获得一个CCO帐号,直接得到Cisco 二级专家的支持,享受CCIE拥有的特权。如果您打算技术移民,通过CCIE认证可以获得额外的加分,在中国通过的CCIE超过半数已经移民到国外。目前,CCIE在美国年薪可达15万美元,还不包括股票期权和其他福利,在中国大陆,一位CCIE的年薪至少在10万元以上,如果加上奖金及其他福利将远远超过这个数目。
要想获得苛刻的CCIE认证,必须先通过笔试,获取资格后才可以参加实验考试。通过了实验才最终成为CCIE。 学习并获得CCIE认证途径大致有两种:第一,自学。要想通过自学方式获取CCIE认证您必须要有两年以上的工作经验,有充足的时间和精力,并要有一个完善的实验环境,此外最重要的是您必须具备坚忍不拔的毅力与永不放弃信念。第二,参加培训。找一家货真价实的培训机构利用业余或集中时间参加培训,充分利用培训机构的实验设备,在良好的学习氛围下,学员之间不但可以互相交流技术更重要的是还可以得到培训机构的CCIE专家辅导,提高学习效率,这是一种事半功倍的途径。
先修课程及考试 CCIE 认证是目前Cisco认证体系中最顶级的证书。要取得CCIE认证证书,需要取得以下课程考试:
1、CCIE资格考试(即笔试,2.5小时) 考试费:¥3000
2、CCIE实验考试(一天) 考试费:¥12000
3、CCIE面试(英文)
笔试部分考试在中国各个城市基本都能考,而实验室部分考试在世界范围内只有9个考场:研究三角园区(美)、圣何塞(美)、悉尼(澳)、香港(中)、北京(中)、班加罗尔(印)、东京(日)、布鲁塞尔(比)、圣保罗(巴)。 分类 Routing & Switching(R&S) 路由交换CCIE
