C. EXCLUSIVE
D. REMOTE
Answer: B C
参考：http://docs.oracle.com/cd/B28359_01/server.111/b28320/initparams198.htm
REMOTE_LOGIN_PASSWORDFILE specifies whether Oracle checks for a password file.
Values:
l shared
One or more databases can use the password file. The password file can contain SYS as well as non-SYS users.
l exclusive
The password file can be used by only one database. The password file can contain SYS as well as non-SYS users.
l none
Oracle ignores any password file. Therefore, privileged users must be authenticated by the operating system.
Note:
When REMOTE_LOGIN_PASSWORDFILE is set to either exclusive or shared, but the password file does not exist, then the behavior is the same as setting REMOTE_LOGIN_PASSWORDFILE to none.来自 “ ITPUB博客 ” ，链接：https://blog.itpub.net/81227/viewspace-2124861/ ，如需转载，请注明出处，否则将追究法律责任。
