Oracle Database 23ai Administration Associate Sample Questions (Q39-Q44):NEW QUESTION # 39
Which two statements are true concerning logical and physical database structures?
  • A. A segment might have only one extent.
  • B. A segment's blocks can be of different sizes.
  • C. Segments can span multiple tablespaces.
  • D. All tablespaces may have one or more data files.
  • E. A segment can span multiple data files in some tablespaces.
  • 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 # 40
Which two statements are true about User Authentication in an Oracle Database?
  • A. Password authentication must be used for system-privileged administrative users.
  • B. REMOTE_LOGIN_PASSWORDFILE must be set to EXCLUSIVE to permit password changes for system-privileged administrative users.
  • C. Operating System authentication may be used for system-privileged administrative users.
  • D. Password File authentication is supported for any type of database user.
  • E. Password File authentication must be used for system-privileged administrative users.
Answer: C,E
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 # 41
Which two statements are true about Fine-Grained Auditing (FGA)?
  • A. FGA policies can be created by a user having EXECUTE privilege on the DBMS_FGA package.
  • B. FGA policies can be created by a user having granted the CREATE_FGA_POLICY role.
  • C. FGA policies can only be created by a user with SYSDBA privilege.
  • D. FGA policies by default can be created by a schema owner on an object in their schema.
  • E. FGA policies can be created by a user having the AUDIT_ADMIN privilege.
Answer: A,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.

NEW QUESTION # 42
Which three statements are true about the Oracle Database server during and immediately after SHUTDOWN TRANSACTIONAL?
  • A. New connection requests made to the database instance are refused.
  • B. Uncommitted transactions are allowed to continue to the next ROLLBACK.
  • C. Uncommitted transactions are allowed to continue to the next COMMIT.
  • D. Instance recovery occurs automatically during the shutdown.
  • E. Sessions remain connected even if they are not running a transaction.
Answer: A,C,E
Explanation:
A .False. Recovery happens on startup, not shutdown.
B .False. TRANSACTIONAL waits for commits or rollbacks, then disconnects.
C .True. New connections are blocked during shutdown.
D .True. Inactive sessions persist until shutdown completes.
E .True. Active transactions can commit before disconnection.

NEW QUESTION # 43
In one of your databases, the user HR has the password HRMGR. You want to connect to a database instance whose listener listens on port 1531 by using this statement: CONNECT HR/HRMGR@orcl. No name server is used. Which statement is true about ORCL?
  • A. It must resolve to a valid connect descriptor in the server's tnsnames.ora file.
  • B. It must be the value of the SERVICE_NAMES parameter on the client side.
  • C. It must be the name of the database to whose instance HR wishes to connect.
  • D. It must be the name of the server running the database to whose instance HR wishes to connect.
  • E. It must resolve to a valid connect descriptor in the client's tnsnames.ora file.
Answer: E
Explanation:
A .False. ORCL is a TNS alias, not necessarily the DB name.
B .True. Must map to a connect descriptor (e.g., HOST=... PORT=1531) in tnsnames.ora.
C .False. It's not the server name but a network alias.
D .False. Client-side tnsnames.ora is used, not server-side.
E .False. SERVICE_NAMES is server-side, not client-side.
