70 150分钟 100题 CCIE笔试
目前CCIE笔试部分的费用是$300USD，一般折合人民币是￥2700RMB。
LAB考试费用是$1250USD，折合人民币￥10375RMB。
CCNA认证(CCNA-思科网络安装和支持认证助理)是整个Cisco认证体系中最初级的认证，同时它也是获得CCNP认证、CCDP认证和CCSP认证的必要条件(CCIP认证、CCIE认证不强制要求)，而且许多Cisco专业认证(Cisco Qualified Specialist)也要求考生首先得具备的CCNA认证。
CCNA认证属于Cisco售后工程师认证体系的入门认证，通过CCNA可以证明你已掌握网络的基本知识，并能初步安装、配置和操作Cisco路由器、交换机及简单的LAN和WAN。CCNA认证表示经过认证的人员具有为小型办公室/家庭办公室(SOHO)市场联网的基本技术和相关知识。通过CCNA认证的专业人员可以在小型网络 (100或100以下个节点)中安装、配置和运行LAN、WAN和拔号访问业务。他们可以使用的协议包括(但不限于):IP, IGRP, IPX, Serial, AppleTalk, Frame Relay, IP RIP, VLAN, RIP, Ethernet, Access Lists.
[b]获得CCNA认证的先决条件[/b]
不需要考生持有任何证书即可报考CCNA，同时对考生的年龄、学历、外语水平均没有硬性规定;
[b]CCNA认证的考试[/b]
现在参加考试有2条途径:一、参加640-801 CCNA这一门考试;二、参加640-821 INTRO和640-811 ICND这两门考试;
[b]CCNA认证的有效期[/b]
CCNA证书的有效期为3年，3年之后需要参加再认证(Recertification)的考试，如果你在这2年时间内考取了更高级别的Cisco认证，则CCNA认证的有效期自动更新。
[b]CCNA的再认证考试[/b]
有效期满之后必须参加640-811 ICND的考试，或者参加任何一科CCNP、CCDP、CCIP、CCSP的考试，再或者参加Cisco专业认证(Cisco Qualified Specialist)中任何一科前缀为642-XXX的考试。 首先简要地说明一下，MCSE和CCNA是两个方向的认证，没有直接的可比较性，两者更多的是知识的互补性，但 www.ITExamPrep.com 还是将大多数初学者提出的问题整理归纳了以下几个方面的比较。 从基础要求来看:CCNA学习时间短
就一般人而言，CCNA涉及了基础的网络知识和设备，还需要CISCO设备的支持，学习周期大约在1-3个月左右
MCSE日常应用多易上手，而且单机就可以实现其大部分认证考试要求，7门科目的学习周期至少为3-6个月左右。
从学习成本来看:CCNA成本低
CCNA只涉及1门考试，考试费用在1250元，如果自学的话，再加上书本教材资料费用不会超过2000元;
而MCSE则有7门考试，光考试费用就为450×7=3150元。
从就业方向来看:CCNA专业性强
CCNA就业方向有系统集成、网络调试安装维护等。
MCSE适宜职位有系统管理员、网络管理员等。
从工作内容来看:CCNA要求动手能力
CCNA则是简单的CISCO设备调试和基础的网络知识;
MCSE是面向Windows环境下的网络、系统的管理、配置、维护;
就一般人而言，我们ITExamPrep.com建议对于急需证书的学员而言，可以选择CCNA，时间短、见效快、性价比高。 [b]CCNP认证概述[/b] CCNP认证(思科认证网络专业人员)表示通过认证的人员具有丰富的网络知识。获得CCNP认证的专业人员可以为具有100到500多个节点的大型企业网络安装、配置和运行LAN、WAN和拔号访问业务。他们可以使用的协议包括，但不限于IP, IGRP, IPX, Async Routing, AppleTalk, Extended Access Lists Route, IP RIP, Redistribution, RIP, Route Summarization,OSPF, VLSM, BGP, Serial, Frame Relay,ISDN, ISL, X.25, DDR,PSTN, PPP, VLAN, Ethernet, Access Lists, 802.10, FDDI, Transparent 和Translational Bridging.
考取CCNP认证的前提是必须首先通过CCNA认证。CCNP考试从1998年设立以来经过多次更改，目前考取最新CCNP有两种途径:一是801+811+821+831，另外一种是891+821+831。
