ALTER TABLESPACE sales_q1 ADD DATAFILE;
Which are two actions, either one of which you could take to ensure that the command executes successfully? (Choose two.)

Ensure that DB_RECOVERY_FILE_DEST and DB_CREATE_FILE_DEST each specify with at least 50 Mb of available space.

Specify a path in the DATAFILE clause of the command specifying a location with at least 100M of available space.

Ensure that DB_CREATE_FILE_DEST specifies a location with at least 100 Mb of available space.
