Oracle Database 23ai Administration Associate Sample Questions (Q93-Q98):
NEW QUESTION # 93
Which two statements are true regarding Oracle database space management within blocks managed by Automatic Segment Space Management (ASSM)?
- A. PCTFREE defaults to 10% for all blocks in all segments for all compression methods.
- B. ASSM assigns blocks to one of the four fullness categories based on what percentage of the block is allocated for rows.
- C. The first block with enough free space to accommodate a row being inserted will always be used for that row.
- D. Update operations always relocate rows into blocks with free space appropriate to the length of the row being updated.
- 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 # 94
Which three statements are true about an SPFILE?
- A. It contains only static initialization parameters.
- B. It must exist for a database instance to start.
- C. It contains initialization parameters whose values can be changed using the ALTER SYSTEM statement.
- D. It can be created by SYS from an idle instance.
- E. It can be used to create a PFILE.
Answer: C,D,E
Explanation:
A .True. CREATE SPFILE FROM PFILE works when idle.
B .False. Includes dynamic parameters too.
C .True. CREATE PFILE FROM SPFILE generates a PFILE.
D .False. A PFILE can start the instance if no SPFILE exists.
E .True. Dynamic parameters (e.g., DB_CACHE_SIZE) are modifiable.
NEW QUESTION # 95
You execute this command: CREATE SMALLFILE TABLESPACE sales DATAFILE '/u01/app/oracle/sales01.dbf' SIZE 5G SEGMENT SPACE MANAGEMENT AUTO; Which two statements are true about the SALES tablespace?
- A. Any data files added to the tablespace must have a size of 5 gigabytes.
- B. It uses the database default block size.
- C. It is a locally managed tablespace.
- D. It must be smaller than the smallest BIGFILE tablespace.
- E. Free space is managed using freelists.
Answer: B,C
Explanation:
A . Free space is managed using freelists.False. The SEGMENT SPACE MANAGEMENT AUTO clause specifies Automatic Segment Space Management (ASSM), which uses bitmaps to track free space, not freelists (used in Manual Segment Space Management).
B . It uses the database default block size.True. The BLOCKSIZE clause is not specified in the command, so the tablespace inherits the database's default block size (typically 8K unless altered via DB_BLOCK_SIZE).
C . It must be smaller than the smallest BIGFILE tablespace.False. There's no such restriction; SMALLFILE and BIGFILE tablespaces differ in structure (multiple vs. single data file), not mandated size relationships.
D . It is a locally managed tablespace.True. In Oracle 23ai, all tablespaces created without an explicit EXTENT MANAGEMENT DICTIONARY clause are locally managed by default, using extent allocation bitmaps in the data file headers.
E . Any data files added to the tablespace must have a size of 5 gigabytes.False. The initial data file is 5G, but additional data files can have different sizes when added using ALTER TABLESPACE ... ADD DATAFILE.
NEW QUESTION # 96
Which two statements are true about advanced connection options supported by Oracle Net for connection to Oracle?
- A. Load Balancing requires the use of a name server.
- B. Source Routing requires the use of encrypted connections.
- C. Connect Time Failover requires the use of Transparent Application Failover (TAF).
- D. Load Balancing can balance the number of connections to dispatchers when using a Shared Server configuration.
- E. Connect Time Failover requires the connect string to have two or more listener addresses configured.
Answer: D,E
Explanation:
A .False. Connect Time Failover doesn't need TAF; TAF is for runtime failover.
B .False. Source Routing doesn't mandate encryption.
C .True. Needs multiple addresses (e.g., (ADDRESS_LIST=...)) for failover.
D .False. Load balancing works with tnsnames.ora, no name server required.
E .True. Balances connections across shared server dispatchers.
NEW QUESTION # 97
You execute this command: CREATE BIGFILE TABLESPACE big_tbs DATAFILE '/u01/oracle/data/big_f1.dbf' SIZE 20G; Sufficient storage is available in filesystem /u01. Which two statements are true about the BIG_TBS tablespace?
- A. It will be a dictionary-managed tablespace by default.
- B. Additional data files may not be added.
- C. AUTOEXTEND is possible for the datafile.
- D. It will always have a 32K blocksize.
- E. It must be bigger than the largest SMALLFILE tablespace.
Answer: B,C
Explanation:
A .False. LMT is default in 23ai.
B .True. Bigfile tablespaces have one data file only.
C .True. AUTOEXTEND works with bigfile data files.
D .False. Block size defaults to DB_BLOCK_SIZE (e.g., 8K).
E .False. No size comparison requirement.
