Oracle 1Z1-182 Exam Syllabus Topics:

Topic	Details
Topic 1	Describe Oracle Database Architecture: This section of the exam measures the skills of Database Administrators and System Architects in understanding the Oracle database architecture. It covers the configurations of Oracle database instances, memory structures like SGA and PGA, and process structures such as background processes. It also explains the logical and physical database structures, including datafiles, control files, and redo log files.
Topic 2	Automated Maintenance: This section measures the skills of Database Administrators in describing automated maintenance tasks within Oracle databases. It focuses on applying automated features to streamline routine maintenance activities.
Topic 3	Describe Managing Database Instances: This section tests the knowledge of Database Administrators in performing essential tasks for managing database instances. It includes starting and shutting down databases, utilizing dynamic performance views, managing initialization parameter files, and using the Automatic Diagnostic Repository (ADR) for troubleshooting.
Topic 4	Introduction to Auditing: This domain tests the abilities of Compliance Specialists in implementing database auditing practices. It includes creating, modifying, and maintaining auditing policies while applying value-based auditing techniques like Fine-Grained Auditing (FGA).
Topic 5	Managing Undo: This domain measures the skills of Database Administrators in using undo data effectively. It compares undo data with redo data and explains temporary undo usage for efficient transaction management.
Topic 6	Managing Storage: This section tests the knowledge of Storage Engineers in managing storage features such as resumable space allocation, segment space-saving, and block space management. It also includes defining segment characteristics to optimize storage utilization.

Oracle Database 23ai Administration Associate Sample Questions (Q35-Q40):

NEW QUESTION # 35
Which three statements are true about an SPFILE?

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

Answer: B,C,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 # 36
Which three statements are true about roles?

A. The SET ROLE statement can disable one or more roles for a session.
B. Roles may be granted to other roles.
C. Roles must be password protected.
D. Object privileges may not be granted to roles.
E. The SET ROLE statement can enable one or more roles for a session.
F. All roles granted to a user are set on default when the user logs in.

Answer: A,B,E

Explanation:
Roles in Oracle manage privileges efficiently. Let's dive into each option:
A . Roles must be password protected.
False. Roles can be password-protected (e.g., CREATE ROLE mgr IDENTIFIED BY secret), but it's optional. Non-protected roles (default) are enabled automatically if granted, requiring no password.
Mechanics:Password-protected roles need SET ROLE mgr IDENTIFIED BY secret, enhancing security for sensitive privileges.
B . Roles may be granted to other roles.
True. Roles can form hierarchies (e.g., GRANT clerk TO mgr), allowing nested privilege management.
Mechanics:A user with mgr inherits clerk privileges indirectly. Revoking clerk from mgr cascades appropriately.
Practical Use:Simplifies complex privilege structures in large organizations.
C . The SET ROLE statement can enable one or more roles for a session.
True. SET ROLE role1, role2; activates specified roles for the session, assuming they're granted and not password-protected (or password is provided).
Mechanics:Enabled roles grant their privileges immediately within the session scope.
D . Object privileges may not be granted to roles.
False. Object privileges (e.g., GRANT SELECT ON emp TO clerk) are a primary use of roles, making this statement incorrect.
Why Incorrect:Roles are designed for this purpose, contradicting the option.
E . All roles granted to a user are set on default when the user logs in.
False. Only roles marked as DEFAULT ROLE (via ALTER USER ... DEFAULT ROLE role1) are enabled at login. Non-default roles require SET ROLE.
Mechanics:Check via SELECT * FROM DBA_ROLE_PRIVS WHERE DEFAULT_ROLE='YES'.
F . The SET ROLE statement can disable one or more roles for a session.
True. SET ROLE NONE disables all roles, or SET ROLE role1 implicitly disables others not listed, providing granular control.
Practical Use:Useful for testing or restricting privileges temporarily.

NEW QUESTION # 37
Which three Oracle database space management features will work with both Dictionary and Locally managed tablespaces?

A. Automatic data file extension (AUTOEXTEND).
B. Oracle Managed Files (OMF).
C. Online table segment shrink.
D. Online index segment shrink.
E. Capacity planning growth reports based on historical data in the Automatic Workload Repository (AWR).

Answer: A,B,E

Explanation:
Dictionary-managed tablespaces (DMTs) use the data dictionary for extent management, whilelocally managed tablespaces (LMTs) use bitmaps. Let's evaluate compatibility:
A . Capacity planning growth reports based on historical data in the Automatic Workload Repository (AWR).
True. AWR tracks space usage (e.g., DBA_HIST_TBSPC_SPACE_USAGE) regardless of tablespace type, enabling growth reports for both DMTs and LMTs.
Mechanics:MMON collects metrics like segment growth, stored in SYSAUX, accessible via EM or scripts.
Practical Use:Helps predict when to add data files, universal across management types.
B . Online table segment shrink.
False. ALTER TABLE ... SHRINK SPACE requires LMTs with Automatic Segment Space Management (ASSM), unavailable in DMTs, which lack bitmap-based free space tracking.
Why Incorrect:DMTs use freelists, incompatible with shrink operations.
C . Online index segment shrink.
False. Like tables, ALTER INDEX ... SHRINK SPACE requires LMTs with ASSM, not supported in DMTs.
Why Incorrect:Same limitation as B; DMTs can't compact online.
D . Oracle Managed Files (OMF).
True. OMF automates file naming and placement (via DB_CREATE_FILE_DEST) for both DMTs and LMTs, agnostic to extent management.
Mechanics:Example: CREATE TABLESPACE ts1; creates an OMF file in either type.
Edge Case:DMTs are rare in 23ai, but OMF still applies.
E . Automatic data file extension (AUTOEXTEND).
True. AUTOEXTEND ON allows data files to grow as needed, supported in both DMTs and LMTs since early versions.
Mechanics:ALTER DATABASE DATAFILE ... AUTOEXTEND ON NEXT 100M; works universally.

NEW QUESTION # 38
Which advisor is used to detect missing or stale object statistics?

A. SQL Access Advisor
B. SQL Performance Analyzer
C. SQL Statistics Advisor
D. SQL Tuning Advisor

Answer: C

Explanation:
B .True. The SQL Statistics Advisor (new in 23ai) identifies stale or missing statistics. Others focus on tuning, performance analysis, or access paths.

NEW QUESTION # 39
What are Optimizer Statistics?

A. Optimizer Statistics are table, column, index, and system statistics used for generating efficient SQL execution plans.
B. Optimizer Statistics are a set of data distribution statistics collected in real time as data is inserted, deleted, or updated, which are stored in AWR and used for generating SQL execution plans.
C. Optimizer Statistics are statistics about data distribution within Oracle Datafiles.
D. Optimizer Statistics are part of system performance statistics stored in AWR required for calculating SQL execution plans.

Answer: A

Explanation:
A .False. Not real-time; collected periodically.
B .False. Not about datafile distribution.
C .True. Includes table, column, index stats for plan generation.
D .False. Stored in data dictionary, not AWR.
