Oracle OCP认证题库变了，052新考题更新整理-24
以前考OCP认证并不难，但今年Oracle对OCP考试进行了更新，OCP的三种题库全变了，比如052题库不光考题变了，而且还在不断的加入新考题，没有比较稳定的题库大大的增加了考试的难度，这里整理了一些052的新题，希望对大家有帮助。
24、YOUR DB_RECOVERY_FILE_DEST_SIZE Is 8G.
Currently, 5G of the space Is used of which 4G consists of obsolete backups.
You execute this command:
SQL> ALTER SYSTEM SET db_recovery_file_dest_size=2G;
What is the outcome?
A) It changes DB_RECOVERY_FILE_DEST_SIZE to 5G.
B) It changes DB_RECOVERY_FILE_DEST_SIZE to 2G without deleting valid backups.
C) It falls because DB_RECOVERY_FILE_DEST_SIZE is a static parameter.
D) It changes DB_RECOVERY_FILE_DEST_SIZE to 2G and deletes the obsolete backups.
E) It fails because the new size is less than 5G.
