Cisco:CCNA安全、语音认证帮助

近日，公司发布三项新专项方向认证：安全（Security）、语音（Voice）和无线（Wireless）。若想获得专项方向的认证，除了要通过标准考试外，考生还需要通过一门专项附加的考试。安全考试(640-553) 和语音考试(640-460)目前已经在Pearson VUE考试中心生效，面对全世界所有考生开放，考试费用为250美元，和标准考试费用相同。而无线考试(640-721) 将会在7月26日开始实施。

教育产品开发部门高级经理斯汀.吉田（Christine Yoshida）表示，这三项考试是思科经过调查全球1500位人力资源部经理后决定推出的。吉田同时表示，调查结果显示众多雇主特别是在那些经济快速发展的国家，现在正在寻找在安全、语音、无线领域中走在前列的网络人才，并且，这些雇主都认为这些都是最紧俏的专业。

   “我们经过调查确实证实了这些专业的巨大需求”，据吉田介绍，这些专项考试在思科认证不断改进的考试改革中充当了很重要的角色。举例来说，一旦安全思科网络设备（SCND）在今年11月停考，安全专项认证将成为公司中级思科认证资深安全工程师（CCSP）的前提考试科目。同样的，语音专项认证将于2009年6月成为思科认证资深语音工程师（CCVP）认证所必须的先决条件。

   尽管思科目前还没有关于无线的资深认证，但吉田补充到，如果哪家公司创建了这个部门，那么的无线认证将会成为一个很好的敲门砖。

一.640-553 Q&A(安全)

Security meets the needs of IT professionals who are responsible for network security. It confirms an individual’s skills for job roles such as Network Security Specialists, Security Administrators, and Network Security Support Engineers. This validates skills including installation, troubleshooting and monitoring of network devices to maintain integrity, confidentiality and availability of data and devices and develops competency in the technologies that uses in its security structure.

Students completing the recommended training will gain an introduction to core security technologies as well as how to develop security policies and mitigate risks. IT organizations that employ Security-holders will have IT staff that can develop a security infrastructure, recognize threats and vulnerabilities to networks, and mitigate security threats.
