    What is the end result of these commands if they are successful?
    RMAN> show retention policy;
    RMAN configuration parameters for database with db_unique_name
    ORCL are: CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
    Backup database tag=gold_copy plus archivelog tag=gold_copy delete input; Backup database
    tag=silver_copy plus archivelog tag=silver_copy delete input;
    A. Attempting to restore silver_copy will fail.
    B. Attempting to restore gold_copy will fail.
    C. Both backups will be available for restore without question.
    D. Attempting to restore gold_copy may or may not succeed.
    E. You will not be able to restore either gold_copy or silver_copy

      Since the retention policy is set to redundancy of 1,the gold_copy(obsolete) backup is not required to meet the retention criteria.Since the backup was not made in a way that will exclude or alter the retention criteria,then the gold_copy backup is no longer needed and may be removed at any time.It is possible that it will still be available for restore purposes,however.
