Which three are true about the MRKT tablespace?

A.
The MRKT tablespace is created as a small file tablespace, because the file size is less than
the minimum required for big file files.

B.
The MRKT tablespace may be dropped if it has no contents.

C.
Users who were using the old default tablespace will have their default tablespaces changed to
the MRKT tablespace.

D.
No more data files can be added to the tablespace.

E.
The relative file number of the tablespace is not stored in rowids for the table rows that are

Explanation:

incorrect:
Not A: To create a bigfile tablespace, specify the BIGFILE keyword of the CREATE TABLESPACE
statement (CREATE BIGFILE TABLESPACE …). Oracle Database automatically creates a locally
managed tablespace with automatic segment space management.
You can specify SIZE in kilobytes (K), megabytes (M), gigabytes (G), or terabytes (T).
Not D: Although automatic segment space management is the default for all new permanent,
locally managed tablespaces, you can explicitly enable it with the SEGMENT SPACE
MANAGEMENT AUTO clause.
