Oracle 11G OCP 1Z0-052 34

（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.

答案：（C）

解析：

C，REMOTE_OS_AUTHENT指定遠端客戶端是否使用OS_AUTHENT_PREFIX引數的值來授權

D（X）. 引數名有誤，應為REMOTE_LOGIN_PASSWORDFILE，指定Oracle是否檢查口令檔案
