NEW QUESTION # 35
Which of the following statements is true about external tables?
- A. They describe how data is stored in the external source.
- B. They are read/write tables.
- C. They describe how the external table layer presents data to the server.
- D. They describe data stored in the database.
Answer: C
Explanation:
A .False. External tables are read-only.
B .True. Defines how external data (e.g., CSV) is mapped to SQL.
C .False. Data is external, not in the DB.
D .False. Storage is external; Oracle doesn't define it.
NEW QUESTION # 36
What is the result of the following command? ALTER PLUGGABLE DATABASE PDB1 DISCARD STATE;
- A. PDB1 is reverted to its default properties, which includes automatic opening after a CDB restart.
- B. It should be used whenever PDB1 open mode needs to be changed.
- C. PDB1 is reverted to its default properties, which includes not to automatically open after a CDB restart.
- D. It is unnecessary if the PDB is in the process of being upgraded.
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).
NEW QUESTION # 37
Examine this command: SQL> ALTER TABLE ORDERS SHRINK SPACE COMPACT; Which two statements are true?
- A. Dependent indexes become UNUSABLE.
- B. The SHRINK operation causes rows to be moved to empty space starting toward the end of the ORDERS segment.
- C. The high-water mark (HWM) of ORDERS is adjusted.
- D. Only queries are allowed on ORDERS while SHRINK is executing.
- E. The SHRINK operation causes rows to be moved to empty space starting from the beginning of the ORDERS segment.
- F. Queries and DML statements are allowed on ORDERS while the SHRINK is executing.
Answer: E,F
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.
NEW QUESTION # 38
Which two statements are true regarding Oracle database space management within blocks managed by Automatic Segment Space Management (ASSM)?
- A. The first block with enough free space to accommodate a row being inserted will always be used for that row.
- B. ASSM assigns blocks to one of the four fullness categories based on what percentage of the block is allocated for rows.
- C. Update operations always relocate rows into blocks with free space appropriate to the length of the row being updated.
- D. PCTFREE defaults to 10% for all blocks in all segments for all compression methods.
- E. Insert operations always insert new rows into blocks with free space appropriate to the length of the row being inserted.
Answer: B,E
Explanation:
A .True. ASSM categorizes blocks (e.g., 0-25%, 25-50%) for efficient space use.
B .False. Updates may cause chaining/migration, not always relocation.
C .True. ASSM optimizes inserts into suitable blocks.
D .False. ASSM uses a bitmap, not necessarily the first block.
E .False. PCTFREE is segment-specific, not universally 10%.
NEW QUESTION # 39
Which three statements are true about Deferred Segment Creation in Oracle databases?
- A. It is supported for SYS-owned tables contained in locally managed tablespaces.
- B. Indexes inherit the DEFERRED or IMMEDIATE segment creation attribute from their parent table.
- C. It is supported for Index Organized Tables (IOTs) contained in locally managed tablespaces.
- D. It is the default behavior for tables and indexes.
- E. Sessions may dynamically switch back and forth from DEFERRED to IMMEDIATE segment creation.
Answer: B,D,E
Explanation:
A .False. IOTs require immediate segment creation.
B .False. SYS-owned tables don't use deferred creation.
C .True. Default since 11gR2, continued in 23ai.
D .True. Indexes inherit this attribute unless overridden.
E .True. Sessions can alter this via DEFERRED_SEGMENT_CREATION.
