Oracle Database 23ai Administration Associate Sample Questions (Q22-Q27):

NEW QUESTION # 22
Which three statements are true about row chaining and row migration done by Oracle database block space management?

A. A migrated row results in an update to any index on the table to point the row ID in the index to the row's new location.
B. Row pieces of a chained row must always reside in different blocks.
C. Insert statements can result in a migrated row.
D. Update statements can result in one or more migrated rows.
E. Update statements can result in one or more chained rows.

Answer: A,D,E

Explanation:
A .True. Migration updates index ROWIDs.
B .True. Updates can migrate rows if space is insufficient.
C .True. Large updates can chain rows across blocks.
D .False. Chained rows may span blocks but aren't required to.
E .False. Inserts don't migrate; they chain if too large initially.

NEW QUESTION # 23
Which statement is true about database links?

A. A database link can be created only between two Oracle databases.
B. A public database link can be used by a user connected to the local database instance to connect to any schema in the remote database instance.
C. A public database link can be created only by SYS.
D. Private database link creation requires the same user to exist in both the local and the remote databases.
E. A database link created in a database allows a connection from that database's instance to the target database's instance, but not vice versa.

Answer: E

Explanation:
Database links enable cross-database queries in Oracle. Let's analyze each option with extensive detail:
A . A public database link can be created only by SYS.
False. Any user with the CREATE PUBLIC DATABASE LINK privilege (not just SYS) can create a public link (e.g., CREATE PUBLIC DATABASE LINK remote_db CONNECT TO scott IDENTIFIED BY tiger USING 'orcl'). While SYS typically has this privilege, it's not exclusive to SYS.
Mechanics:Privilege is granted via GRANT CREATE PUBLIC DATABASE LINK TO user;. Public links are accessible to all users in the local DB.
Why Incorrect:Overly restrictive; Oracle's security model allows delegation.
B . A database link can be created only between two Oracle databases.
False. Database links can connect to non-Oracle databases using Oracle Heterogeneous Services or gateways (e.g., ODBC or JDBC drivers), such as linking to SQL Server. Example: CREATE DATABASE LINK mssql_link USING 'hsodbc';.
Mechanics:Requires configuration of hs_ parameters in init.ora and a gateway listener.
Historical Note:Heterogeneous links were introduced in 8i, expanded in 23ai for cloud integration.
C . A database link created in a database allows a connection from that database's instance to the target database's instance, but not vice versa.
True. A database link is unidirectional; it enables queries from the local instance to the remote instance (e.g., SELECT * FROM emp@remote_db), but the remote instance can't use it to query back unless a separate link is created there.
Mechanics:Stored in DBA_DB_LINKS, the link defines a one-way connection via a TNS alias or connect string.
Practical Use:Ensures controlled access; bidirectional access requires explicit configuration.
Edge Case:Loops are prevented unless explicitly designed with mutual links.
D . A public database link can be used by a user connected to the local database instance to connect to any schema in the remote database instance.
False. Public links allow all local users to use them, but access to remote schemas depends on the link's credentials (e.g., CONNECT TO scott) and the user's remote privileges. "Any schema" overstates it; access is limited to what the link's user can see.
Why Incorrect:Misrepresents privilege scope; remote schema access isn't universal.
E . Private database link creation requires the same user to exist in both the local and the remote databases.
False. A private link (e.g., CREATE DATABASE LINK my_linkCONNECT TO scott IDENTIFIED BY tiger USING 'orcl') requires the remote user (scott) to exist, but the local creator (e.g., HR) need not match. The link is owned locally and authenticated remotely.
Mechanics:Only the CREATE DATABASE LINK privilege is needed locally.

NEW QUESTION # 24
Which two statements are true about the UNLIMITED TABLESPACE system privilege and space quota?

A. By default, users have no quota on their default permanent tablespace.
B. It is overridden by a space quota specified for the user.
C. It allows a user to have unlimited space in any tablespace in the database.
D. It allows a user to have unlimited space only in their default permanent tablespace.
E. It allows a role to have unlimited space in any tablespace in the database.

Answer: B,C

Explanation:
A .True. Grants unlimited space across all tablespaces.
B .True. Explicit quotas override the privilege.
C .False. Not limited to default tablespace.
D .False. Roles can't have this privilege directly.
E .False. Default is zero quota unless specified.

NEW QUESTION # 25
Script abc.sql must be executed to perform a certain task. User HR with password HR exists in the target database and the account is unlocked. The TNSNAMES.ORA file is up to date. Examine this command attempted by the user: $ sqlplus hr/hr@orcl @abc. What will happen and why?

A. The command fails because the script must refer to the full path name.
B. The command fails and reports an error because @ is used twice.
C. The command succeeds and HR will be connected to the orcl database instance, and the abc script will be executed.
D. The command succeeds and HR will be connected to the orcl database and after logging out to the abc database.
E. The command succeeds and HR will be connected to the orcl database instance, and the abc script will be executed.

Answer: E

Explanation:
A .False. "Logging out to the abc database" is nonsensical; abc is a script, not a database.
B .False. SQL*Plus finds abc.sql in the current directory by default; a full path isn't required unless it's elsewhere.
C .False. The first @ specifies the TNS alias (orcl), the second runs the script (@abc); this is valid syntax.
D & E.True (identical options). The command connects to orcl via TNSNAMES.ORA, authenticates HR, and executes abc.sql.
Mechanics:sqlplus hr/hr@orcl resolves orcl to a listener address, connects, and@abc runs the script post-login.

NEW QUESTION # 26
You want to apply the principle of Least Privilege in all your live databases. One of your requirements is to revoke unnecessary privileges from all users who have them using Privilege Analysis. Which three types of analyses can be done using the DBMS_PRIVILEGE_CAPTURE package?

A. Analysis of privileges that a user has on their own schema objects that they did use.
B. Analysis of privileges that a user has on their own schema objects that they did not use.
C. Analysis of privileges granted directly to a role that are then used by a user who has been granted that role.
D. Analysis of all privileges used by all users but excluding administrative users in the database.
E. Analysis of all privileges used by all users including administrative users in the database.
F. Analysis of privileges granted indirectly to a role that are then used by a user who has beengranted that role.

Answer: A,B,F

Explanation:
A .True. Captures unused self-owned object privileges.
B .False. SYS is excluded from capture.
C .False. No exclusion option for admin users.
D .False. Direct role grants aren't separately analyzed.
E .True. Tracks indirect role privileges used.
F .True. Identifies used self-owned privileges.
