Oracle Database 23ai Administration Associate Sample Questions (Q79-Q84):

NEW QUESTION # 79
Which two statements are true about views used for viewing tablespace and datafile information?

A. V$TABLESPACE displays information that is contained in the control file about tablespaces.
B. Tablespace free space can be viewed in V$TABLESPACE.
C. Tablespace free space can be viewed in DBA_TABLESPACES.
D. V$TABLESPACE displays information about tablespaces contained in the data dictionary.
E. A datafile can be renamed when the database is in MOUNT state and the new file name is displayed when querying DBA_DATA_FILES after the database is opened.

Answer: A,E

Explanation:
A .False. V$TABLESPACE doesn't show free space directly.
B .False. It's from the control file, not the data dictionary.
C .True. Renaming in MOUNT state updates DBA_DATA_FILES post-open.
D .False. DBA_TABLESPACES shows attributes, not free space directly (use DBA_FREE_SPACE).
E .True. V$TABLESPACE reflects control file data.

NEW QUESTION # 80
Which three statements are true about roles?

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

Answer: A,B,C

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 # 81
Which three statements are true about Automatic Diagnostic Repository (ADR)?

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

Answer: A,B,D

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 # 82
Which two actions can you perform using DBCA for an existing database?

A. Create a template that can be used to clone the database.
B. Change the character set.
C. Create nonstandard block size tablespaces.
D. Create an additional listener.
E. Change the server mode from dedicated to shared, and vice versa.

Answer: A,E

Explanation:
A .False. DBCA can't change character sets post-creation.
B .False. Listeners are managed via NetCA or lsnrctl.
C .True. DBCA can switch server modes for existing DBs.
D .False. Tablespaces are created via SQL, not DBCA for existing DBs.
E .True. DBCA can generate clone templates from existing DBs.

NEW QUESTION # 83
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. A segment's blocks can be of different sizes.
E. A segment might have only one extent.
F. Segments can span multiple tablespaces.

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.
