实际的。就是这样一直来到介意当我想到思科新推出的思科认证技师的一个压倒一切的字今日（CCT）证书公布。不过话又说回来，我一直是思科TAC的粉丝，这并不奇怪，通过TAC开发，一个非常特殊目的的证书，确实是实用的。所有这三个新的CCT证书的具体侧重于硬件的安装任务，包括热插拔，验证和故障排除。这个帖子着眼于这些新证书的基本知识。
The Core: Things Break, TAC Dispatches, Technicians Install
这些新证书背后的故事来自于思科服务的全中断/修复世界由思科技术支持中心（TAC）驱动。
当然，事情打破，无论是硬件还是软件。当硬件中断，根据不同的服务合同，思科可能不仅给你新的硬件，他们可能会为您安装它。所以，你有问题。你叫TAC。您都同意的硬件需要更换，所以他们送了硬件和技术人员用新的来取代旧的。
一些安装的只需要一点点知识，但有些需要比螺丝刀技能多。有时，技术人员只是替换一个机架安装盒与另一 - 删除旧的电缆，拧开盒子从机架上卸下，装上新的一个，并重新电缆就像它以前。但是他们仍然要确定正确的盒子，安装电缆的正确方法，等等。此外，一些安装需要更精明 - 例如，也许这是一个卡或在6500开关SUP，支持热插拔卡，以及技术人员需要按照一定的步骤。不遵循这些步骤可能会导致停电，或炒新卡，或炒所有的牌，所有坏的东西。也许这将是连接到CLI是一个好主意，请确保路由器或交换机识别新卡，离开工地前。
Finally, Cisco does not keep badged Cisco employees in every town or village of the world just waiting for a part to show up in the local shipping office. Instead, Cisco uses 3RD第三方服务公司谁做使工作人员在不同地区。很长一段时间过去，当TAC分派专人现场安装盒或卡，它并不总是一个大众品牌的思科员工即显示出来，而是它的一个承包商。
The 3RD方技术人员需要的技能，以及思科需要知道，他们派遣他们去现场之前拥有的技能。在过去的几年中，所有证明的技术人员的工作是通过思科及其合作伙伴之间的内部流程。
CCT：对什么思科始终是公开的认证证书完成
Cisco's new CCT certifications essentially create three different public certifications that the Cisco TAC will use for 3RD方技术人员。从思科的新闻稿引述：
由思科技术支持中心开发的，CCT认证验证的硬件现场工程师谁进行现场支持的工作技能，维护思科设备，并与思科技术支持中心有效地工作，以解决现场支持问题。
思科也说，他们将考虑其他CCT认证，但最初，这三个CCT证书是：
If you follow those links, and look at the exam topics, you'll see what's on each exam. Just based on that info, if I had to pick one word to describe my first impression, that word would have to be "practical". For instance, consider the RSTECH 640-692 exam, the exam that gets you a CCT R/S cert. Your job: install and troubleshoot routers and switches. So the exam topics include things like:
- 设置配置寄存器
- 使用ping，远程登录，SSH
- 识别不同类型的接口
- 升级IOS（TFTP，FTP，XMODEM等）
- 在笔记本电脑上的IP设置，以便您可以连接到该设备
In short, if you show up as the on-site technician, you need skills to get the hardware working well enough so that the remote TAC engineer can gain access, at a bare minimum. Ideally, you can confirm the problem the TAC already identified, replace the hardware, and verify it's working. It might even be routine, planned maintenance, but you need to do the work, and make sure the new card of box really works. Regardless, all the exam topics zero in on those practical tasks you better know how to do if you are the person, and the only person, onsite.
CCT Training Matches the Technician Workstyle
思科已经采取了不同的方法来相对于很多其他职业认证的CCT培训。对于CCT，训练时间较短，更加模块化和在线。
Focusing on CCT Routing and Switching for a moment, to get the skills to pass the CCT R/S exam, you can spend $299 directly with Cisco to get an e-learning course called RSTECH (which is the same name as the exam). You get a year's subscription. You can take the course from anywhere that you have a web browser and Internet access. It's modularized so you can take it in small chunks. And it's only 5-6 hours cumulative. So it's not going to require technicians to be out of the office for a week, and it lets them fit in the learning as time permits.
If you think about this from the TAC perspective, they obviously want their 3RD方技术人员有很强的实力，所以使训练容易获得艾滋病这一目标。雇主节省了旅行，并在$ 299，这个价格似乎没有不坏。
However, just like with their other certs, Cisco does not require that you take the course to take the exam. The exam is offered at Vue, just like most other Cisco exams. To take the exam, you register at Vue.com, and show up at a Vue testing center, just like you would for the CCENT, CCNA, or any other Cisco career cert exam. Per the pre-announce briefing info, it's a 90 minute exam, with 60-70 questions, of the same general style as CCENT (multichoice, testlets, and the like). In the US, the cost is $125 for the exam.
CCT R/S has no prerequisites, but CCT TP and CCT DC do: namely, they require CCT R/S. So, start with CCT R/S, and then take the other two as needed. For recert, you can re-take the same exam, or just pass most any of the other career cert exams - CCENT, CCNA, CCDA, CCNP, etc.
