You execute this command: CONFIGURE RETENTION POLICY CLEAR; What is the retention policy set to after running the command?

Answer: A

Explanation: By default, RMAN keeps one full copy of the database. B is incorrect because a retention policy is defined. C is incorrect because there is no relationship between the RMAN records in the control file and the retention policy. D and E are incorrect because they are not the default values for the RMAN retention policy.
