Oracle Database 23ai Administration Associate Sample Questions (Q76-Q81):NEW QUESTION # 76
Which three tasks are part of the predefined Automated Maintenance Tasks?
  • A. Automatic segment and segment statistics advisor tasks.
  • B. Automatic Backups of the database system files.
  • C. Automatic Optimizer Statistics Collection.
  • D. Automatic notification tasks.
  • E. Automatic SQL Plan Management advisor tasks.
  • F. Automatic error and failure log collection tasks.
Answer: A,C,E
Explanation:
A .False. Backups are via RMAN, not AMTs.
B .True. Stats collection is an AMT.
C .False. Error logging isn't an AMT.
D .True. SPM tasks are included.
E .False. Notifications aren't AMTs.
F .True. Segment Advisor is an AMT.

NEW QUESTION # 77
You must create a tablespace of nonstandard block size in a new file system and plan to use this command: CREATE TABLESPACE ns_tbs DATAFILE '/u02/oracle/data/nstbs_f01.dbf' SIZE 100G BLOCKSIZE 32K; The standard block size is 8K, but other nonstandard block sizes will also be used. Which two are requirements for this command to succeed?
  • A. DB_32K_CACHE_SIZE should be set to a value greater than DB_CACHE_SIZE.
  • B. The /u02 file system must have at least 100G space for the datafile.
  • C. DB_32K_CACHE_SIZE must be set to a value that can be accommodated in the SGA.
  • D. DB_32K_CACHE_SIZE must be less than DB_CACHE_SIZE.
  • E. The operating system must use a 32K block size.
Answer: B,C
Explanation:
A .False. No such restriction exists; DB_32K_CACHE_SIZE is independent of DB_CACHE_SIZE.
B .True. A nonstandard block size (32K) requires a corresponding cache (DB_32K_CACHE_SIZE) set to a non-zero value within SGA limits.
C .False. OS block size is irrelevant; Oracle manages its own block sizes.
D .False. No requirement for it to exceed DB_CACHE_SIZE.
E .True. The file system must have 100G available for the datafile.

NEW QUESTION # 78
Which statement is true about database links?
  • A. 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.
  • B. Private database link creation requires the same user to exist in both the local and the remote databases.
  • C. A public database link can be created only by SYS.
  • D. A public database link can be used by any user allowing remote database instance connection for selecting schema data.
  • E. A database link can be created only between two Oracle databases.
Answer: A
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 # 79
Which three actions are ways to apply the principle of least privilege?
  • A. Revoking execute privilege on UTL_SMTP, UTL_TCP, UTL_HTTP, and UTL_FILE from the roles/users (assuming typo for duplicate option).
  • B. Setting the O7_DICTIONARY_ACCESSIBILITY parameter to TRUE.
  • C. Using Access Control Lists (ACLs).
  • D. Enabling Unified Auditing.
  • E. Setting the REMOTE_OS_AUTHENT 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 # 80
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 File authentication is supported for any type of database user.
  • D. Password authentication must be used for system-privileged administrative users.
  • E. Operating System authentication may be used for system-privileged administrative users.
Answer: B,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.
