第3题：

NAC's(Network Access Control)role is to restrict network access to only compliant endpoints and(66)users. However, NAC is not a complete LAN(67)solution; additional proactive and(68)security measures must be implemented. Nevis is the first and only comprehensive LAN security solution that combines deep security processing of every packet at 10Gbps, ensuring a high level of security plus application availability and performance. Nevis integrates NAC as the first line of LAN security(69). In addition to NAC, enterprises need to implement role-based network access control as well as critical proactive security measures — real-time, multilevel(70)inspection and microsecond threat containment.

A．automated

B．distinguished

C．authenticated

D．destructed


正确答案：C
解析：网络访问控制(NAC)的作用是限制对网络的访问，只允许注册的终端和认证的用户访问网络。然而NAC不是一个完整的LAN安全解决方案，另外还要实现主动的和被动的安全手段。Nevis是第一个也是仅有的全面的LAN安全解决方案，它以10Gbps速率对每一个分组进行深度的安全处理，在提供高级别安全的同时能保证网络应用的可利用性和适当的性能。Nevis集成了NAC作为LAN的第一道安全防线。此外，企业还需要实现基于角色的网络访问控制以及起关键作用的主动安全测试——实时的多级安全威胁检测和微秒级的安全威胁堵截。集中的安全策略配置、管理和报告使其能够迅速地对问题进行分析，对用户的活动进行跟踪，这些都是实时可见的，也是历史可查的。
