A．create
B．created
C．creating
D．creative
正确答案：D
解析：软件设计是一个创造性的过程，它需要大量设计者的才能。设计从书本里是学不到的，它必须通过实践，从经验中学习，并且对现有的系统研究才能掌握。一个设计很好的软件系统易于实现、易于维护，而且容易理解和可靠性强。设计不佳的软件系统，尽管他们可能维护代价昂贵，但是却难以测试，并且可靠性差。 -
第2题：
Virtualization is an approach to IT that pools and shares(71)so that utilization is optimized and supplies automatically meet demand. Traditional IT environments are often silos, where both technology and human(72)are aligned around an application or business function. With a virtualized(73), people, processes, and technology are focused on meeting service levels,(74)is allocated dynamically, resources are optimized, and the entire infrastructure is simplified and flexible. We offer a broad spectrum of virtualization(75)that allows customers to choose the most appropriate path and optimization focus for their IT infrastructure resources.
A．advantages
B．resources
C．benefits
D．precedents
正确答案：B
解析：虚拟化是IT行业缓存和共享资源的一种方法，通过这种方法可以更好地利用资源，并且自动提供资源以满足需求。传统的IT环境通常是一个竖井，技术和人力资源都是围绕应用或商业功能来安排的。利用虚拟化的架构，人员、过程和技术都集中于满足服务的程度，生产量被动态地分配，资源得到优化，而且整个架构得以简化，变得很灵活。我们提供了广泛的虚拟化解决方案，允许客户为他们的IT资源的基础架构选择最适用的路线和优化的重点。 -

第5题：
A transport layer protocol has several responsibilities. One is to create a process-to-process (program-to-program) communication; TCP uses port (71) to accomplish this. Another responsibility of a transport layer protocol is to create a (72) and error-control mechanism at the transport level. TCP uses a sliding (73) protocol to achieve flow control. It uses the acknowledgment packet, time-out, and retransmission to achieve (74) control. The transport layer is also responsible for providing a connection mechanism for the application program. The application program sends (75) of data to the transport layer. It is the responsibility of the transport layer at the sending station to make a connection with the receiver.
