F. Oracle Net Manager can be used to centrally configure listeners on any database server target.

Answer: A,B,D

Explanation:
A .False. Net Manager is local, not centralized.
B .False. NetCA can run standalone.
C .True. EMCC manages service names centrally.
D .True. EMCC configures listeners on managed targets.
E .False. lsnrctl starts a default listener if no listener.ora exists.
F .True. Net Manager configures local tnsnames.ora.

NEW QUESTION # 25
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 any user allowing remote database instance connection for selecting schema data.
C. A database link created in a database allows a connection from that database's instance to the target database's instance for selecting schema data.
D. Private database link creation requires the same user to exist in both the local and the remote databases.
E. A public database link can be created only by SYS.

Answer: C

Explanation:
A .False. Links can connect to non-Oracle DBs via gateways.
B .False. No such user requirement; authentication is separate.
C .False. Any user with CREATE PUBLIC DATABASE LINK can create one.
D .True. Links enable remote schema access (e.g., SELECT * FROM emp@remote).
E .False. Public links allow access, but privileges on remote objects are needed.

NEW QUESTION # 26
You execute the SHUTDOWN ABORT command. Which two statements are true?

A. Subsequent instance startup performs media recovery.
B. A checkpoint is written.
C. Data files are closed normally.
D. Uncommitted transactions are not rolled back by the shutdown.
E. Subsequent instance startup performs instance recovery.

Answer: D,E

Explanation:
A .False. No checkpoint occurs with ABORT.
B .False. Instance recovery, not media recovery, is needed.
C .True. Crash recovery rolls back uncommitted changes on startup.
D .False. Files aren't closed cleanly with ABORT.
E .True. Shutdown doesn't roll back; recovery does.

NEW QUESTION # 27
Which two statements are true about the tools used to configure Oracle Net Services?

A. Enterprise Manager Cloud Control can be used to centrally configure net service names for any database server target.

D. The Oracle Net Configuration Assistant is only used when running the Oracle installer.
E. Oracle Net Manager can be used to centrally configure listeners on any database server target.

Answer: A,C

Explanation:
A .False. lsnrctl can start a default listener without listener.ora.
B .True. EMCC provides centralized Net Services configuration.
C .False. NetCA can run standalone, not just during installation.
D .True. Net Manager configures local naming (e.g., TNSNAMES.ORA).
E .False. Net Manager is local, not centralized like EMCC.

NEW QUESTION # 28
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 is supported for any type of database user.
C. Operating System authentication may be used for system-privileged administrative users.
D. Password authentication must be used for system-privileged administrative users.
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.
