●下列对集成服务( IntServ)模型和区分服务(DiffServ)模型描述正确的是(24) 。(24)A.IP的Qos技术主要是集成服务模型和区分服务模型B.集成服务模型和区分服务模型无法进行结合C.集成服务扩展性好,可以应用在不同规模的网络中;区分服务扩展性差,不能应用在大型网络中D.集成服务模型可以针对单个业务(比如一路电话)进行Qos保证;区分服务模型不针对单个业务,而是针对一类业务进行Qos保证
●下列有关SAN与NAS的说法中错误的是:(64)。(64)ASAN采用FibreChannel协议,NAS采用TCP/IP协议BNAS主要应用于NFS和CIFS中的文件共享CSAN的优点是高可用性、高可扩展性DNAS距离限制多,不易于部署和管理
VPN网络部署QOS中,说法正确的是()。 A.QOS的流分类动作必须在VPN封装前完成B.带宽保证,队列调度等QOS功能需要在设备的出口处进行部署C.QOS可以在通过Internet组建的VPN网络中进行部署D.QOS的流分类动作可以在VPN封装完成后实施
以下关于DiffServ的说法,不正确的是( )。A.DiffServ最主要的优势是弱化了对信令的依赖B.DiffServ提供全网端到端的QoS保证C.DiffServ将QoS的一致性范围缩小到每个区域之中,从而降低了这种模型实现的复杂性。D.DiffServ无需像IntServ在每个路由器上为每个业务流保留"软状态",避免了大量的资源预留信息的传递,具有更好的可扩展性
