题目1
答案：B
解析：客户仅提供应用程序的代码，代码需要在供应商提供的计算平台上执行，这个云计算系统是平台即服务(PaaS)计算的例子。
Cloud computing systems where the customer only provides application code for execution on a vendor-supplied computing platform are examples of platform as a service (PaaS) computing.
题目2
答案：D
解析：数据中心的湿度应保持在40%至60%之间。低于此范围的值会增加静电风险，而高于此范围的值可能产生损坏设备的水分。
Data center humidity should be maintained between 40 percent and 60 percent. Values below this range increase the risk of static electricity, while values above this range may generate moisture that damages equipment.
题目3
答案：D
解析：Alex可以使用数字版权管理技术将PDF的使用限制在付费客户身上。虽然DRM很少是一个完美的解决方案，但在这种情况下，它可能符合其组织的需求。EDM是电子舞曲，他的顾客可能会欣赏它，但不能解决问题。加密和数字签名有助于保证文件的安全，并证明他们来自哪些人，但无法解决Alex正在需要处理的权利管理问题。
Alex can use digital rights management technology to limit use of the PDFs to paying customers. While DRM is rarely a perfect solution, in this case, it may fit his organization’s needs. EDM is electronic dance music, which his customers may appreciate but which won’t solve the problem. Encryption and digital signatures can help to keep the files secure and to prove who they came from but won’t solve the rights management issue Alex is tackling.
