NEW QUESTION # 74
Examine this command: SQL> ALTER TABLE ORDERS SHRINK SPACE COMPACT; Which two statements are true?

A. The SHRINK operation causes rows to be moved to empty space starting from the beginning of the ORDERS segment.
B. Only queries are allowed on ORDERS while SHRINK is executing.
C. Queries and DML statements are allowed on ORDERS while the SHRINK is executing.
D. The high-water mark (HWM) of ORDERS is adjusted.
E. The SHRINK operation causes rows to be moved to empty space starting toward the end of the ORDERS segment.
F. Dependent indexes become UNUSABLE.

Answer: A,C

Explanation:
A . Dependent indexes become UNUSABLE.False. SHRINK SPACE COMPACT does not affect index usability; only SHRINK SPACE without COMPACT may require index maintenance if CASCADE is omitted.
B . ... starting toward the end of the ORDERS segment.False. Rows are compacted toward the beginning of the segment, not the end.
C . Only queries are allowed ...False. Both queries and DML are allowed during SHRINK SPACE COMPACT as it's an online operation.
D . The high-water mark (HWM) of ORDERS is adjusted.False. COMPACT moves rows but doesn't adjust the HWM; the full SHRINK SPACE command is needed for HWM adjustment.
E . Queries and DML statements are allowed ...True. This is an online operation in 23ai, allowing concurrent access.
F . ... starting from the beginning of the ORDERS segment.True. Rows are moved to fill free space from the segment's start.

B. It is unnecessary if the PDB is in the process of being upgraded.
C. PDB1 is reverted to its default properties, which includes not to automatically open after a CDB restart.
D. PDB1 is reverted to its default properties, which includes automatic opening after a CDB restart.

Answer: C

Explanation:
A .False. DISCARD STATE isn't tied to upgrades; it resets PDB startup behavior.
B .True. Discards saved state, reverting PDB1 to manual open mode (not auto-open) after CDB restart.
C .False. Default is not auto-open; it's manual unless explicitly saved as OPEN.
D .False. Used for state management, not general mode changes (e.g., OPEN READ WRITE).

C. When the DBA revokes the CREATE VIEW privilege from USR2, it is revoked from USR3.
D. When the DBA revokes the CREATE VIEW privilege from USR1, it is neither revoked from USR2 nor USR3.
E. USR1 can revoke the CREATE VIEW privilege from USR3.

Answer: C,D

Explanation:
A .False. Revoking from USR1 doesn't cascade due to WITH ADMIN OPTION.
B .True. Revoking from USR2 cascades to USR3 because USR2 granted it.
C .False. DBA can revoke the full privilege, not just ADMIN OPTION.
D .False. USR1 can't revoke from USR3 directly; only the grantor (USR2) can.

D. They support DELETEs, which transparently deletes records in the file system as if they were table rows.
E. The results of a complex join or aggregating function or both can be unloaded to a file for transportation to other systems.

Answer: B,E

Explanation:
A .False. External tables are read-only; no DELETE.
B .False. Require OPEN state, unlike V$ views.
C .False. No UPDATE support; read-only.
