随着 IT 服务运营过程中知识的不断沉淀和积累、客户期望值的不断提高,必然带来不间断的服务改进需求,所以需要对 IT 服务进行持续改进,持续改进方法的过程中包括下面七个阶段(① ② ③④ ⑤ ⑥ ⑦未按顺序排列):①分析信息和数据;②实施改进;③识别改进战略/策略;④收集数据;⑤识别需要测量什么;⑥展示并使用信息;⑦处理数据。按照持续改进方法的正确过程顺序,下面 (2017.53) 是正确选项。
Typically, an IP address refers to an individual host on a particular network.IP also accommodates addresses that refer to a group of hosts on one or more networks.Such addresses are referred to as multicast addresses,and the act of sending a packet from a source to the members of a( 71 )group is referred to as multicasting.

Multicasting done ( 72 ) the scope of a single LAN segment is straightforward.IEEE 802 and other LAN protocols include provision for MAC-level multicast addresses.A packet with a multicast address is transmitted on a LAN Segment.Those stations that are members of the( 73 )multicast group recognize the multicast address and( 74 )the packet.In this case,only a single copy of the packet is ever transmitted.This technique works because of the( 75 )nature of a LAN:A transmission from anyone station is received by all other station on the LAN.
