Exam 1Z1-182 Bible & 1Z1-182 Valid Dumps Sheet

Success in the test of the Oracle Database 23ai Administration Associate (1Z1-182) certification proves your technical knowledge and skills. The 1Z1-182 exam credential paves the way toward landing high-paying jobs or promotions in your organization. Many people who attempt the Oracle Database 23ai Administration Associate (1Z1-182) exam questions don't find updated practice questions. Due to this they don't prepare as per the current 1Z1-182 examination content and fail the final test.

Oracle Database 23ai Administration Associate Sample Questions (Q85-Q90):

NEW QUESTION # 85
In one of your databases, you create a user, HR, and then execute this command: GRANT CREATE SESSION TO hr WITH ADMIN OPTION; Which three actions can HR perform?

A. Log in to the database instance.
B. Revoke the CREATE SESSION privilege from other users.
C. Execute DML statements in the HR schema.
D. Revoke the CREATE SESSION privilege from user HR.
E. Grant the CREATE SESSION privilege with ADMIN OPTION to other users.
F. Execute DDL statements in the HR schema.

Answer: A,B,E

Explanation:
A .False. CREATE SESSION doesn't grant DML rights.
B .True. CREATE SESSION allows login.
C .True. WITH ADMIN OPTION allows revoking from others HR granted it to.
D .True. WITH ADMIN OPTION permits granting with the same option.
E .False. Users can't revoke their own privileges.
F .False. DDL requires additional privileges (e.g., CREATE TABLE).

NEW QUESTION # 86
Which three statements are true about an SPFILE?

A. It must exist for a database instance to start.
B. It can be used to create a PFILE.
C. It can be created by SYS from an idle instance.
D. It contains initialization parameters whose values can be changed using the ALTER SYSTEM statement.
E. It contains only static initialization parameters.

Answer: B,C,D

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 # 87
One of your database instances was shut down normally and then started in NOMOUNT state. You then executed this command: ALTER DATABASE MOUNT; Which two of these actions are performed?

A. Control files are read.
B. The initialization parameter file is read.
C. Oracle shared memory structures are allocated.
D. Online redo logs are opened.
E. The alert log has instance startup details written to it.
F. Online data files are opened.

Answer: A,E

Explanation:
A .False. Data files open in OPEN.
B .False. Redo logs open in OPEN.
C .False. PFILE/SPFILE is read at NOMOUNT.
D .False. SGA is allocated at NOMOUNT.
E .True. Alert log records mount event.
F .True. Control files are read in MOUNT.

NEW QUESTION # 88
Which two statements are true concerning logical and physical database structures?

A. A segment can span multiple data files in some tablespaces.
B. A segment's blocks can be of different sizes.
C. All tablespaces may have one or more data files.
D. Segments can span multiple tablespaces.
E. A segment might have only one extent.
F. A segment's blocks can be of different sizes.

Answer: A,E

Explanation:
False. All blocks in a segment use the tablespace's block size (e.g., 8KB). While a database can have tablespaces with different block sizes (e.g., 8KB, 32KB), a single segment's blocks are uniform, as it resides in one tablespace.
Explanation:
Logical structures (e.g., segments, extents) map to physical structures (e.g., data files, blocks). Let's dissect each option:
A : A segment can span multiple data files in some tablespaces.
True. A segment (e.g., a table or index) is a logical entity stored in a tablespace. In a smallfile tablespace (default in Oracle), a segment's extents can span multiple data files if the tablespace has multiple files and space allocation requires it. This is common in large tables or when autoextend adds new files.
Mechanics:Oracle allocates extents across available data files in a round-robin fashion (with ASSM) or as needed, ensuring the segment's data is distributed. This doesn't apply to bigfile tablespaces, which use a single data file.
Example:A 10GB table in a tablespace with two 5GB data files will span both.
B : Segments can span multiple tablespaces.
False. A segment is confined to a single tablespace. Oracle enforces this to maintain logical separation (e.g., a table's data stays in its assigned tablespace). Partitioned tables can have partitions in different tablespaces, but each partition is a separate segment.
Why Not:The segment header and extent map reside in one tablespace, preventing cross-tablespace spanning for a single segment.
C : A segment might have only one extent.
True. A segment starts with one extent upon creation (e.g., a small table or index). If no further growth occurs, it remains a single-extent segment. This is common with small objects or when INITIAL extent size suffices.
Mechanics:In locally managed tablespaces (default), the initial extent is allocated based on INITIAL or tablespace defaults (e.g., 64KB), and additional extents are added only as needed.
D : All tablespaces may have one or more data files.
False. Bigfile tablespaces are restricted to one data file (up to 128TB). Smallfile tablespaces (traditional) can have multiple data files (up to 1022), but the "all" phrasing makes this false due to bigfile exceptions.
Clarification:The question's intent may assume smallfile tablespaces, but Oracle 23ai supports both types.

NEW QUESTION # 89
At which two container database levels can COMMON Unified Audit Policies be used?

A. At the PDB level if the policy is created by a COMMON user.
B. At the Application Root level of an Application Container.
C. At the CDB level.
D. At any level by using the COMMON option in the policy.
E. COMMON Unified Audit Policies can only be created at CDB level to monitor DBA operation at any level.

Answer: A,C

Explanation:
A .False. Not limited to CDB; PDBs can use common policies.
B .True. Common policies apply at CDB level.
C .False. Application Root uses app-specific policies.
D .False. "COMMON option" isn't a feature; policies are common by creation context.
E .True. A common user can create policies for PDBs.
