Without a doubt, there is one thing that can assist them with perceiving this interest and clearing their Oracle Database 23ai Administration Associate (1Z1-182) exam with flying colors. Oracle 1Z1-182 dumps merge all that gigantic and the competitor doesn't require to purchase the aide or different books to review. They have this test material and need nothing else for planning Oracle Database 23ai Administration Associate exam.

Oracle Database 23ai Administration Associate Sample Questions (Q95-Q100):

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. Free space is managed using freelists.
C. It is a locally managed tablespace.
D. It uses the database default block size.
E. It must be smaller than the smallest BIGFILE tablespace.

Answer: C,D

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 are true about shrinking a segment online?

A. To shrink a table it must have a PRIMARY KEY constraint.
B. To shrink a table it must have a UNIQUE KEY constraint.
C. It must be in a tablespace that uses Automatic Segment Space Management (ASSM).
D. To shrink a table it must have row movement enabled.
E. It is not possible to shrink either indexes or Index Organized Tables (IOTs).

Answer: C,D

Explanation:
A .True. ROW MOVEMENT must be enabled for SHRINK SPACE.
B .False. Indexes and IOTs can be shrunk with CASCADE.
C .False. No such constraint requirement.
D .True. ASSM is required for online shrinking.
E .False. No primary key requirement.

NEW QUESTION # 97
Which three statements are true about Automatic Diagnostic Repository (ADR)?

A. It can be used for the problem diagnosis of a database when that database's instance is down.
B. It is only used for Oracle database diagnostic information.
C. The ADR base is specified in the DIAGNOSTIC_DEST database parameter.
D. It is held inside an Oracle database schema.
E. It is a file-based repository held outside any database.

Answer: A,C,E

Explanation:
A .True. ADR is a file system directory structure (e.g., /u01/app/oracle/diag), external to the database.
B .False. ADR also stores diagnostics for non-database components (e.g., ASM, listener).
C .False. It's file-based, not schema-based.
D .True. ADR logs (e.g., alert logs, trace files) are accessible even if the instance is down.
E .True. DIAGNOSTIC_DEST sets the ADR base directory.

NEW QUESTION # 98
Your data center uses Oracle Managed Files (OMF) for all databases. All tablespaces are smallfile tablespaces. SALES_Q1 is a permanent user-defined tablespace in the SALES database. The following command is about to be issued by a DBA logged in to the SALES database: ALTER TABLESPACE sales_q1 ADD DATAFILE; Which two actions independently ensure that the command executes successfully?

A. Ensure that DB_RECOVERY_FILE_DEST and DB_CREATE_FILE_DEST each specify locations with at least 50 MB of available space.
B. Ensure that DB_CREATE_FILE_DEST specifies a location with at least 100 MB of available space.
C. Add the AUTOEXTEND ON clause with NEXT set to 100M.
D. Ensure that DB_RECOVERY_FILE_DEST and DB_CREATE_FILE_DEST each specify locations with at least 50 MB of available space.
E. Specify a path in the DATAFILE clause of the command specifying a location with at least 100 MB of available space.

Answer: A,B

Explanation:
With OMF enabled, Oracle automatically manages file creation. The command ALTER TABLESPACE sales_q1 ADD DATAFILE without a file specification relies on initialization parameters:
A . Specify a path in the DATAFILE clause ... with at least 100 MB of available space.False. With OMF, explicitly specifying a path overrides OMF behavior, but it's not required for success if OMF parameters are set correctly.
B . Add the AUTOEXTEND ON clause with NEXT set to 100M.False. AUTOEXTEND is optional and affects file growth, not the initial creation success, which depends on available space in the OMF location.
C . Ensure that DB_RECOVERY_FILE_DEST and DB_CREATE_FILE_DEST each specify locations with at least 50 MB of available space.True. If both parameters are set,Oracle may use either for data files (depending on context), and sufficient space (e.g., 50 MB minimum for a smallfile) ensures success.
D . Ensure that DB_CREATE_FILE_DEST specifies a location with at least 100 MB of available space.True. This is the primary OMF parameter for data files; sufficient space (typically 100 MB minimum for a new file) guarantees the command succeeds.
E . Ensure that DB_RECOVERY_FILE_DEST and DB_CREATE_FILE_DEST each specify locations with at least 50 MB of available space.False. This is redundant with C; only one needs sufficient space, though C's phrasing makes it a valid independent action.

NEW QUESTION # 99
Which two account management capabilities can be configured using Oracle profiles?

A. The number of days for which an account may be inactive before it is locked.
B. The number of days for which an account may be logged in to one or more sessions before it is locked.
C. The ability to prevent a password from ever being reused.
D. The maximum number of sessions permitted for a user before the password must be changed.
E. The maximum amount of CPU time allowed for a user's sessions before their account is locked.

Answer: A,C

Explanation:
A .False. Session limits don't tie to password changes.
B .False. CPU limits don't lock accounts.
C .False. No direct "logged-in days" parameter.
D .True. PASSWORD_REUSE_MAX=UNLIMITED prevents reuse.
E .True. PASSWORD_LOCK_TIME sets inactivity lockout.
