Explanation:
The failure resolution policy specifies what should happen on the primary database if all the standby databases ion the configuration are unable to archive the redo logs. To specify guaranteed protection, you must establish the PROTECTED mode for the primary database. The PROTECTED mode will establish a zero divergence and zero data loss configuration. Incorrect Answer:
1: The standby database is not protected against write operations by this operation. The standby database can be mounted for recovery or open as read-only database.
2: The primary database is not protected against write operations.
4: The primary, not standby, database is protected against data loss and data divergence.
