Oracle Database 23ai Administration Associate Sample Questions (Q28-Q33):

NEW QUESTION # 28
Which three actions are ways to apply the principle of least privilege?

A. Using Access Control Lists (ACLs).
B. Setting the REMOTE_OS_AUTHENT parameter to TRUE.
C. Revoking execute privilege on UTL_SMTP, UTL_TCP, UTL_HTTP, and UTL_FILE from the roles/users (assuming typo for duplicate option).
D. Enabling Unified Auditing.
E. Setting the O7_DICTIONARY_ACCESSIBILITY parameter to TRUE.

Answer: A,C,D

Explanation:
A .True. Auditing tracks privilege use, enforcing least privilege.
B .True. Revoking unnecessary PL/SQL access limits capabilities.
C .True. ACLs restrict network access precisely.
D .False. TRUE relaxes dictionary access, violating least privilege.
E .False. TRUE allows risky OS auth, weakening security.

NEW QUESTION # 29
Which three are benefits of using temp UNDO when performing DML on global temporary tables?

A. It reduces I/Os to the SYSAUX tablespace.
B. It reduces the amount of redo generated.
C. It permits DML on global temporary tables even if the database is opened read-only.
D. It reduces I/Os to the SYSTEM tablespace.
E. It reduces the amount of UNDO stored in the UNDO tablespace.

Answer: B,D,E

Explanation:
Temp UNDO, introduced in Oracle 12c and refined in 23ai, stores undo for global temporary tables (GTTs) in temporary tablespaces:
A . It permits DML on GTTs even if the database is opened read-only.False. In read-only mode, DML on GTTs is allowed regardless of temp UNDO, as GTT data is session-private, but temp UNDO doesn't specifically enable this.
B . It reduces the amount of UNDO stored in the UNDO tablespace.True. Temp UNDO stores undo in the temporary tablespace, reducing usage of the permanent UNDO tablespace.
C . It reduces I/Os to the SYSTEM tablespace.True. By avoiding permanent undo, it reduces metadata updates in the SYSTEM tablespace related to undo management.
D . It reduces the amount of redo generated.True. Temp UNDO changes are not redo-logged to the same extent as permanent undo, minimizing redo generation.
E . It reduces I/Os to the SYSAUX tablespace.False. SYSAUX is unrelated to undo management; temp UNDO affects temporary and SYSTEM tablespaces.

NEW QUESTION # 30
You have connected to a PDB to perform the administration operations of changing and verifying a system parameter that is PDB_MODIFIABLE. What is the appropriate mode to open the PDB to achieve this?

A. RESTRICTED WRITE ONLY
B. RESTRICTED READ ONLY
C. READ ONLY
D. READ WRITE

Answer: D

Explanation:
To change a PDB_MODIFIABLE parameter, the PDB must be in READ WRITE mode, allowing ALTER SYSTEM commands to modify parameters stored in the PDB's SPFILE or memory. READONLY modes prevent modifications, and no RESTRICTED WRITE ONLY mode exists.

NEW QUESTION # 31
Which two statements are true about User Authentication in an Oracle Database?

A. REMOTE_LOGIN_PASSWORDFILE must be set to EXCLUSIVE to permit password changes for system-privileged administrative users.
B. Password File authentication must be used for system-privileged administrative users.
C. Password authentication must be used for system-privileged administrative users.
D. Operating System authentication may be used for system-privileged administrative users.
E. Password File authentication is supported for any type of database user.

Answer: B,D

Explanation:
User authentication in Oracle 23ai determines how users (especially administrative ones) connect to the database. Let's analyze each option with extensive detail:
A . Operating System authentication may be used for system-privileged administrative users.
True. OS authentication allows users mapped to OS accounts (e.g., ops$oracle) to connect without a password, often used for administrative users like SYS or SYSTEM. This is configured by creating an externally authenticated user (e.g., CREATE USER "OPS$ORACLE" IDENTIFIED EXTERNALLY) and relies on the OS to verify identity.
Mechanics:When a user logs in via sqlplus / as sysdba, Oracle checks the OS user against the dba group (Unix) or ORA_DBA (Windows). If matched, no password is needed, leveraging OS security.
Practical Use:Common for DBAs managing local instances, reducing password management overhead.
Edge Case:Requires REMOTE_LOGIN_PASSWORDFILE=NONE for exclusive OS auth, but this isn't mandatory if a password file exists alongside.
Historical Note:Introduced in early Oracle versions, this remains a robust option in 23ai for local admin access.
B . Password authentication must be used for system-privileged administrative users.
False. "Must" is incorrect; password authentication (e.g., sqlplus sys/password) is an option, not a requirement. OS authentication or password file authentication can also be used for users like SYS. This option overstates the necessity of password-based login.
Why Incorrect:Oracle's flexibility allows multiple methods, contradicting the absolute phrasing here.
C . Password File authentication is supported for any type of database user.
False. Password file authentication is restricted to users with SYSDBA, SYSOPER, or similar system privileges (e.g., SYSBACKUP). Regular users (e.g., HR) can't use the password file (orapw<sid>); they rely on database authentication (passwords stored in the DB) or external methods.
Mechanics:The password file stores hashed credentials for privileged users, checked during remote AS SYSDBA logins.
Why Incorrect:Extending this to "any user" ignores Oracle's security model limiting password file usage.
D . REMOTE_LOGIN_PASSWORDFILE must be set to EXCLUSIVE to permit password changes for system-privileged administrative users.
False. REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE allows a dedicated password file for one instance, enabling password changes via ALTER USER SYS IDENTIFIED BY newpass. However, SHARED mode also permits changes for SYS, though not for other users added to the file. The "must" overstates the requirement; it's sufficient, not necessary.
Mechanics:EXCLUSIVE locks the file to one DB, while SHARED allows multiple DBs to use it, with restrictions on non-SYS users.
E . Password File authentication must be used for system-privileged administrative users.
True. For remote administrative access (e.g., sqlplus sys/password@orcl as sysdba), a password file is mandatory when REMOTE_LOGIN_PASSWORDFILE is EXCLUSIVE or SHARED. Local OS authentication is an alternative, but for network-based admin tasks, the password file is required, making this statement true in that context.
Mechanics:Set via orapwd (e.g., orapwd file=orapworcl password=oracle entries=10), enabling remote SYSDBA logins.
Edge Case:If REMOTE_LOGIN_PASSWORDFILE=NONE, only OS auth works locally, but this isn't the default or typical setup.

NEW QUESTION # 32
Which two statements are true about Fine-Grained Auditing (FGA)?

A. FGA policies can be created by a user having granted the CREATE_FGA_POLICY role.
B. FGA policies can be created by a user having EXECUTE privilege on the DBMS_FGA package.
C. FGA policies by default can be created by a schema owner on an object in their schema.
D. FGA policies can only be created by a user with SYSDBA privilege.
E. FGA policies can be created by a user having the AUDIT_ADMIN privilege.

Answer: B,E

Explanation:
A .False. Schema owners need EXECUTE on DBMS_FGA.
B .False. Not limited to SYSDBA.
C .True. AUDIT_ADMIN includes FGA creation rights.
D .False. No such role exists.
E .True. DBMS_FGA.ADD_POLICY requires this privilege.
