Title : Unified Communications Express AM
1. Telecommunications manager: "I have heard that the speech quality of VoIP is poor. I think I would rather wait until the technology has really been tested."
What is the most appropriate response to the telecommunications manager objection to deploying a Cisco Unified Communications solution?
Select the best response.
A. VoIP is already a proven technology and the speech quality would be as good as, if not better than, a traditional phone system.
B. Cisco Unified Communications is an enhancement of VoIP, so it offers better quality.
C. Today, there is enough bandwidth in the Internet, so QoS for speech would be guaranteed.
D. Policies applied to traffic on a Cisco Unified Communications network are set to give a higher priority to voice packets than to data packets, which guarantees that speech quality is as good as, if not better than, a traditional phone system.
Answer: D
我认为，获取 证书、学习CISCO技术有一个理由：即你掌握CISCO产品技术和你拥有网络相关使用经验的一种书面形式的保证。我并不认为所有获得思科证书的人的水平是一样的，那些学习并在实际工作中实践过的人比依靠考试资料而获得证书的人更应被选择为雇员。证书从来都不应被认为是经验的替代品。对那些刚刚入门或从事初级网络工作的人，有证书比没有证书好；但对于从事中级或高级网络技术工作的人，证书不如经验重要，尤其是对网络这个行业来说。
