34. A user, who is authenticated externally, logs in to a remote machine and connects to the database

instance. What action would you take to ensure that a user cannot connect to the database instance by

merely logging in to a remote machine?

A.Set REMOTE_OS_ROLES to FALSE.

B.Set the OS_ROLES parameter to FALSE.

C.Set the REMOTE_OS_AUTHENT parameter to FALSE.

D.Set the REMOTE_LOGIN_PASSWORD_FILE parameter to NONE.

Answer: C

答案解析：

限制远程数据库验证：默认情况下，REMOTE_OS_AUTHENT参数设置为FALSE。一定不要更改这个设置，除非可确保所有客户机都能适当地验证用户。在引入了安全外部口令存储(在Oracle Database 10g发行版2 中提供)后，允许远程操作系统验证就有了令人信服的理由。
