OCP CBT Question 580

Please solve the following question.

A tablespace `APP_DATA` has a datafile `appdata01.dbf` of size 500MB. Due to increased data volume, you need to extend this datafile to 1GB. Which command will achieve this without taking the tablespace offline?

ALTER DATABASE DATAFILE '/path/to/appdata01.dbf' RESIZE 512M;

ALTER TABLESPACE APP_DATA ADD DATAFILE '/path/to/appdata02.dbf' SIZE 512M;

ALTER DATABASE DATAFILE '/path/to/appdata01.dbf' AUTOEXTEND ON MAXSIZE 1G;

ALTER DATABASE DATAFILE '/path/to/appdata01.dbf' RESIZE 1G;
