问题 单项选择题

The European Union’s Barcelona summit, which ended on March 16th, was played out against the usual backdrop of noisy "anti-globalization" demonstrations and massive security. If nothing else, the demonstrations illustrated that economic liberalization in Europe--the meeting’s main topic--presents genuine political difficulties. Influential sections of public opinion continue to oppose anything that they imagine threatens "social Europe", the ideal of a cradle-to-grave welfare state.

In this climate of public opinion, it is not surprising that the outcome in Barcelona was modest. The totemic issue was opening up Europe’s energy markets. The French government has fought hard to preserve a protected market at home for its state-owned national champion, Electricite de France (EDF). At Barcelona it made a well-flagged tactical retreat. The summiteers concluded that from 2004 industrial users across Europe would be able to choose from competing energy suppliers, which should account for "at least" 60% of the market.

Since Europe’s energy market is worth 350 billion ( $ 309 billion) a year and affects just about every business, this is a breakthrough. But even the energy deal has disappointing aspects. Confining competition to business users makes it harder to show that economic liberalization is the friend rather than the foe of the ordinary person. It also allows EDF to keep its monopoly in the most profitable chunk of the French market.

In other areas, especially to do with Europe’s tough labor markets, the EU is actually going backwards. The summiteers declared that "disincentives against taking up jobs" should be removed; 20m jobs should be created within the EU by 2010. But only three days after a Barcelona jamboree, the European Commission endorsed a new law that would give all temporary-agency workers the same rights as full-timers within six weeks of getting their feet under the desk. Six out of 20 commissioners did, unusually, vote against the measure--a blatant piece of re-regulation--but the social affairs commissioner, Anna Diamantopoulou, was unrepentant, indeed triumphant. A dissatisfied liberaliser in the commission called the directive "an absolute disaster".

The summit’s other achievements are still more fragile. Europe’s leaders promised to increase spending on "research and development" from its current figure of 1.9% of GDP a year to 3%. But how will European politicians compel businesses to invest more in research Nobody seems to know. And the one big research project agreed on at Barcelona, the Galileo satellite-positioning system, which is supposed to cost 3.2 billion of public money, is of dubious commercial value, since the Europeans already enjoy free access to the Americans’ GPA system. Edward Bannerman, head of economics at the Centre for European Reform, a Blairite think-tank, calls Galileo "the common agricultural policy in space.\

We learn from the text that Edward Bannerman is probably()

A. an enthusiast in agricultural policy

B. a tough leader in social affairs

C. an doubter of spending on research

D. a pioneer in space exploration

阅读以下关于网络性能评估和规划方面的技术说明,根据要求回答问题1~问题6。
[说明]
某企业销售部和售后服务部的网络拓扑结构如图2-20所示。


这两个部门的员工抱怨由于新服务器的加入网络运行速率比以前慢了。网络规划设计师郭工在调查期间利用手持式诊断工具记录了如下信息。
(1)服务器A(Server A)同时是销售部和服务部的文件和打印服务器,其网络连接运行在78%的平均利用率上。
(2)销售部的网络平均利用率为45%。
(3)服务器B(Server B)是一台文件服务器,其上驻留了各种类型的文件,并允许销售部的工作站进行在线文件编辑。它占用销售部所有网络利用率的20%。
(4)销售部的两个有限授权用户经常以对等工作方式进行网络互联操作。他们占用了销售部所有网络利用率的5%。
(5)售后服务部的网络平均利用率为65%。
(6)服务器C(Server C)中有一套销售部和服务部员工频繁使用的图像库应用软件,它占用销售部、服务部两个部门的所有网络利用率的15%。
(7)流媒体服务器(Server D)中驻留一套流媒体应用软件,由服务部用于售后服务等培训工作。该应用占用了部门网络利用率的20%。
网络规划设计师郭工在调查中了解到该企业工程技术部门已花费了所有资金,已经没有了购买新的网络设备的预算资金。但该工程技术部可在三层交换机(Switch1)上提供6个1Gb/s交换端口,另外还可提供3台100Mb/s的交换机、4张1Gb/s网卡和一箱回收的10/100Mb/s网卡。

该企业进行子网规划IP地址块为:192.168.10.0/24。在表2-10中其他部门的工作站数量为60台,请将该表中的(1)~(5)空缺处可分配的主机地址范围或子网掩码填写完整。
