An application uses a single service account for all database access.One of the risks of this approach is:应用程序对所有数据库访问使用单个服务帐户。这种方法的风险之一是::()?
(A)It constrains the application from running parallel processes它限制应用程序运行并行进程
(B)The database runs out of threads数据库用完线程
(C)The application freezes more often应用程序更频繁地死机
(D)The ability to trace who made changes to the data能够跟踪谁对数据进行了更改
(E)The data becomes out of order数据变得无序 答案解析: service account指的是非操作人员帐户,如SQL SERVER中的SYSTEM帐户等,他们是没有密码的;如果所有数据库都用一个service account,如dev,prd,uat,那假设其中某个地方引致这个account出现问题(如拒绝访问WINDOW的某个目录,而这个目录刚好是保存数据的父目录),将会出现所有环境不能访问;又或者在修改后台服务帐户权限后,导至前台桌面应用不能访问(Tableau会有此问题) BTW:该题目不严谨,不需要深究,属1%的S+题目
