Oracle Database 23ai Administration Associate Sample Questions (Q59-Q64):

NEW QUESTION # 59
Which three statements are true about resumable space allocation in Oracle databases?

A. All sessions must have the same timeout value when waiting for resumable space allocations.
B. Resumable space allocation is only possible with locally managed tablespaces.
C. The AFTER SUSPEND event trigger can itself be suspended due to space conditions.
D. Resumable space allocation may be enabled for some sessions and not others.
E. A user's session may be suspended and resumed multiple times.
F. A user's session may be suspended even if the user has the UNLIMITED TABLESPACE system privilege.

Answer: D,E,F

Explanation:
A .True. Enabled per session with ALTER SESSION ENABLE RESUMABLE.
B .True. Multiple suspensions can occur in one session.
C .False. Works with dictionary-managed tablespaces too.
D .False. Timeout is session-specific.
E .True. Privilege doesn't prevent suspension; quota limits do.
F .False. Triggers execute but can't suspend themselves.

NEW QUESTION # 60
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. AUTOEXTEND is possible for the datafile.
C. It must be bigger than the largest SMALLFILE tablespace.
D. It will always have a 32K blocksize.
E. Additional data files may not be added.

Answer: B,E

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.

NEW QUESTION # 61
Which three relationships between instances and Oracle databases are possible without using Multi-tenant?

A. One instance on one server mounting multiple databases.
B. One instance on one server mounting and opening multiple databases.
C. One instance on one server mounting and opening one database.
D. Two or more instances on separate servers all mounting and opening the same database.
E. One instance on one server that has no database mounted.

Answer: C,D,E

Explanation:
A .False. One instance can't mount multiple DBs without multitenant.
B .True. RAC allows multiple instances to share one DB.
C .False. Same as A; not possible without CDB.
D .True. An instance can start in NOMOUNT with no DB.
E .True. Standard single-instance configuration.

NEW QUESTION # 62
Examine these commands:
[oracle@host01 ~]$ sqlplus u1/oracle
SQL> SELECT * FROM emp;
ENO ENAME DN
-------------------------
1 Alan 2
2 Ben 2
SQL> exit
[oracle@host01 ~]$ cat emp.dat
1, Alan, 2
3, Curl, 4
4, Bob, 4
[oracle@host01 ~]$ sqlldr u1/oracle TABLE=emp
Which two statements are true?

A. It overwrites the data for Alan and adds data for Curl and Bob.
B. It generates a log that contains control file entries, which can be used with normal SQL*Loader operations.
C. It overwrites all data in EMP with data from EMP.DAT.
D. It appends data from EMP.DAT to EMP.
E. It generates a SQL script that it uses to load data from EMP.DAT to EMP.

Answer: B,D

Explanation:
SQL*Loader (sqlldr) loads data from external files into Oracle tables. The command sqlldr u1/oracle TABLE=emp uses defaults since no control file is specified. Let's evaluate:
A . It overwrites the data for Alan and adds data for Curl and Bob.
False. SQLLoader's default mode is APPEND, not REPLACE. It doesn't "overwrite" existing rows unless REPLACE or TRUNCATE is specified in a control file. Here, row 1, Alan, 2 exists, and SQLLoader will either skip it (if a primary key rejects duplicates) or raise an error, but it won't overwrite. 3, Curl, 4 and 4, Bob, 4 are appended.
Mechanics:Without a control file, SQL*Loader assumes APPEND and matches columns positionally (ENO, ENAME, DN).
B . It generates a log that contains control file entries, which can be used with normal SQL*Loader operations.
True. SQL*Loader always generates a log file (e.g., emp.log) when invoked. With no control file specified, it auto-generates one internally and logs it, including entries like LOAD DATA INFILE 'emp.dat' APPEND INTO TABLE emp FIELDS TERMINATED BY ',' (ENO, ENAME, DN). This can be reused.
Practical Use:The log's control section is editable for future runs (e.g., changing to REPLACE).
C . It appends data from EMP.DAT to EMP.
True. Default behavior without a control file is APPEND, adding new rows (3, Curl, 4 and 4, Bob, 4) to EMP. Existing rows (1, Alan, 2, 2, Ben, 2) remain unless constrained (e.g., unique key violations).
Mechanics:SQL*Loader processes each line of emp.dat, skipping duplicates if constrained, appending otherwise.
D . It generates a SQL script that it uses to load data from EMP.DAT to EMP.
False. SQL*Loader doesn't generate SQL scripts; it uses direct path or conventional path loading, not SQL scripts. The log contains control file syntax, not a script.
E . It overwrites all data in EMP with data from EMP.DAT.
False. REPLACE or TRUNCATE would overwrite, but these require a control file with those options. Default APPEND preserves existing data.

NEW QUESTION # 63
Which two statements are true regarding Oracle database space management within blocks managed by Automatic Segment Space Management (ASSM)?

A. Insert operations always insert new rows into blocks with free space appropriate to the length of the row being inserted.
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. PCTFREE defaults to 10% for all blocks in all segments for all compression methods.

Answer: A,B

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%.
