问题 WLANs are increasingly popular because they enable cost—effective connections among people and applications that were not possible in the past．For example，WLAN—based applications can enable fine—grained management of supply(16)t0 improve their efficiency and reduce(17)  ．WLANs can also enable entirely new business processes．To cite but one example，hospitals are using WLAN—enabled point—of-care(18)to reduce errors and improve overall patient care．WLAN management solutions provide a variety of other benefits that can be substantial but difficult to measure．For example，they can protect corporate date by preventing  (19)throuth rogue access points．They can improve overall network management by integrating with customers’existing systems．Fortunately，it isn’t necessary to measure these benefits to j ustify investing in WLAN management solutions，which can quickly pay for themselves simply by minimizing time-(20)deployment and administrative chores．(2008年上半年试题)

C、effective
D、connected
答案B
解析 译文：无线局域网(WLAN)日益普及起来，这是因为它能够在用户和应用之间有效地建立连接，这在过去是很难做到的。例如，基于WLAN的应用可以对供应链进行细粒度的管理，从而改进效率，减少开销。WLAN也可以创造全新的商业过程。仅举出其中的一个例子，医院使用基于WLAN的护理点应用来减少差错，全面改进病员护理。WLAN管理解决方案提供的各种实质上的好处是很难度量的。例如，它可以保护公司的数据，防止恶意的访问。它可以全面地改进网络管理，并集成到用户现有的系统中。幸好，我们无须量化这些收益来证明WLAN管理解决方案的合理性，因为它能很快地补偿由于部署这些应用和管理事务而付出的时间开销。
