Examine the commands executed in a DBA session:
SQL> CREATE BIGFILE TABLESPACE MRKT
2 DATAFILE '/u01/app/oracle/oradata/orcl/mrkt.dbf' size 10M LOGGING
3 EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO;
Tablespace created.
SQL> ALTER DATABASE DEFAULT TABLESPACE MRKT;
Database altered.
Which two statements are true regarding the MRKT tablespace? (Choose two.)
A.No more data files can be added to the tablespace.
B.Segment space is managed by free lists in the tablespace.
C.A user created without being assigned a default tablespace uses this tablespace.
D.The tablespace can be dropped with the current setting with segments present in it.
BIGFILE 只能有一个数据文件，A 对
ALTER DATABASE DEFAULT TABLESPACE MRKT;将默认表空间修改成 MRKT，C 对
创建 MRKT 的时候，Oracle 自动创建本地管理表空间和自动段空间管理（ASSM）。 B 错
默认表空间不能直接 drop，D 错
