Which statement about SQL Server security settings for CA ARCserve Backup is TRUE?

You must use Windows authentication for SQL Server 2000 when the database is running in a cluster.

For SQL Server authentication, you must specify a user account with system administrator access privileges.

In all cases, a Windows or domain administrator has system administrator access privileges for the database automatically.

If you change the authentication setting, if you are using SQL Server 2000 or later, you only need to update the setting for one instance of SQL Server.
