You want to estimate the size of a table by using the Oracle Enterprise Manager.  On which data is the size of the table NOT based？（）

A. creating a table in your schema and you exceed your allocated space quota on the tablespace
B. executing a long query that involves a sort operation and the statement runs out of temporary space
C. loading data into tables by using the SQL*Loader and the number of extents in the table reaches the maximum limit
D. creating a table in a dictionary-managed tablespace with an explicit MAXEXTENTS setting which results in an out of space error

A. ALTER DATABASE ADD LOGFILE MEMBER ’/disk1/oradata/redo01b.log’ TO GROUP 1；
B. ALTER DATABASE ADD LOGFILE MEMBER ’/disk2/oradata/redo01b.log’ TO GROUP 1；
C. ALTER DATABASE ADD LOGFILE MEMBER ’/disk1/oradata/redo02b.log’ TO GROUP 2；
D. ALTER DATABASE ADD LOGFILE MEMBER ’/disk2/oradata/redo02b.log’ TO GROUP 2；
E. ALTER DATABASE ADD LOGFILE MEMBER ’/disk1/oradata/redo3b.log’ TO GROUP 3；
F. ALTER DATABASE ADD LOGFILE MEMBER ’/disk2/oradata/redo3b.log’ TO GROUP3；

A. No warning level or critical level alert will be generated.
B. A warning level alert will never be generated， but a critical level alert will be generated when 97 percent space of the DATA1 tablespace is used.
C. A critical level alert will never be generated， but a warning level alert will be generated when 85 percent space of the DATA1 tablespace is used.
D. A warning level alert will be generated at 85 percent space usage of the DATA1 tablespace， and a critical level alert is generated at 97 percent space usage of the DATA1 tablespace.
