Oracle Database 23ai Administration Associate Sample Questions (Q67-Q72):

NEW QUESTION # 67
Which three statements are true about the tools used to configure Oracle Net Services?

A. The Oracle Net Configuration Assistant is only used when running the Oracle installer.
B. Enterprise Manager Cloud Control can be used to centrally configure listeners on any managed database server.
C. Oracle Net Manager can be used to centrally configure listeners on any database server target.
D. The lsnrctl utility requires a listener.ora file to exist before it is started.
E. Enterprise Manager Cloud Control can be used to centrally configure net service names for any database server target.
F. Oracle Net Manager can be used to locally configure naming methods on a database server.

Answer: B,E,F

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 # 68
Which three actions are ways to apply the principle of least privilege?

A. Setting the O7_DICTIONARY_ACCESSIBILITY parameter to TRUE.
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. Using Access Control Lists (ACLs).

Answer: C,D,E

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 # 69
Which two methods can be used to purge audit records of the Unified Audits?

A. Use DBMS_AUDIT_MGMT.CLEAN_AUDIT_TRAIL as a privileged user to manually purge audit records.
B. Only the owner of a Unified Audit Policy can purge audit records by resetting the policy.
C. Only viewed audit records can be purged from Unified Audits.
D. Use DBMS_AUDIT_MGMT.DELETE_AUDIT_RECORDS('POLICY_NAME') as a privileged user to manually purge audit records of a specified Unified Policy.
E. Use DBMS_AUDIT_MGMT.CREATE_PURGE_JOB as a privileged user to schedule an automatic purge job.
F. Use DBMS_AUDIT_MGMT.DELETE_AUDIT_RECORDS('POLICY_NAME') as a privileged user to manually purge audit records of a specified Unified Policy.

Answer: A,E

Explanation:
False. No such procedure exists in DBMS_AUDIT_MGMT. The package offers CLEAN_AUDIT_TRAIL and CREATE_PURGE_JOB, but nothing targets a specific policy's records by name in this format. You can filter records in UNIFIED_AUDIT_TRAIL by policy (e.g., SELECT * WHERE UNIFIED_AUDIT_POLICIES = 'POLICY_NAME'), but purging is all-or-nothing or time-based, not policy-specific via a single command.
Why Incorrect:This appears to be a fabricated or misinterpreted option, possibly confusing audit policy management with trail purging.
Explanation:
Unified Auditing in Oracle 23ai consolidates audit records into a single trail, managed via the DBMS_AUDIT_MGMT package. Let's evaluate each option with extensive detail:
A : Only viewed audit records can be purged from Unified Audits.
False. There's no concept of "viewed" audit records restricting purging. Unified Audit records (stored in UNIFIED_AUDIT_TRAIL) can be purged based on time, policy, or manual intervention, regardless of whether they've been viewed. This option misrepresents audit management capabilities.
Mechanics:Purging is controlled by retention policies or explicit commands, not view status. For example, records older than a set retention period (e.g., 90 days via DBMS_AUDIT_MGMT.SET_AUDIT_TRAIL_PROPERTY) are eligible for purging.
Why Incorrect:No Oracle documentation ties purging to viewing, making this a fabricated limitation.
B : Use DBMS_AUDIT_MGMT.CREATE_PURGE_JOB as a privileged user toschedule an automatic purge job.
True. This procedure creates a scheduled job to automatically purge audit records based on a retention policy or custom criteria. It's a standard method for ongoing audit trail maintenance, requiring privileges like AUDIT_ADMIN.
Mechanics:Example: BEGIN DBMS_AUDIT_MGMT.CREATE_PURGE_JOB(AUDIT_TRAIL_TYPE => DBMS_AUDIT_MGMT.AUDIT_TRAIL_UNIFIED, JOB_FREQUENCY => 'DAILY', JOB_STATUS => DBMS_AUDIT_MGMT.JOB_ENABLED); END;. This schedules daily purges of old records, using the retention period set by SET_AUDIT_TRAIL_PROPERTY.
Practical Use:Ideal for production environments to prevent the audit trail from growing indefinitely (e.g., avoiding tablespace exhaustion in SYSAUX).
Edge Case:If no retention period is set, the job purges nothing until configured, highlighting the need for prior setup.
C : Only the owner of a Unified Audit Policy can purge audit records by resetting the policy.
False. Audit policies don't have "owners" in the traditional sense; they're created by users with AUDIT_ADMIN and managed globally. Resetting or disabling a policy (e.g., NOAUDIT POLICY my_policy) stops auditing but doesn't purge existing records. Purging is a separate operation via DBMS_AUDIT_MGMT.
Why Incorrect:This conflates policy management with audit trail cleanup, which are distinct in Oracle.
D : Use DBMS_AUDIT_MGMT.CLEAN_AUDIT_TRAIL as a privileged user to manually purge audit records.
True. This procedure manually purges all Unified Audit records up to the current timestamp (or a specified time), requiring AUDIT_ADMIN privileges. It's a one-time cleanup tool.
Mechanics:Example: BEGIN DBMS_AUDIT_MGMT.CLEAN_AUDIT_TRAIL(AUDIT_TRAIL_TYPE => DBMS_AUDIT_MGMT.AUDIT_TRAIL_UNIFIED, USE_LAST_ARCH_TIMESTAMP => FALSE); END;. This clears the entire trail unless restricted by a timestamp.
Practical Use:Useful for immediate space reclamation or post-incident cleanup, unlike scheduled jobs.
Edge Case:If the audit trail is large, this may require significant undo space and time, potentially impacting performance.

NEW QUESTION # 70
Which three statements are true about Automatic Diagnostic Repository (ADR)?

A. It is a file-based repository held outside any database.
B. It is only used for Oracle database diagnostic information.
C. It can be used for the problem diagnosis of a database when that database's instance is down.
D. It is held inside an Oracle database schema.
E. The ADR base is specified in the DIAGNOSTIC_DEST database parameter.

Answer: A,C,E

Explanation:
A .True. ADR is a file system directory structure (e.g., /u01/app/oracle/diag), external to the database.
B .False. ADR also stores diagnostics for non-database components (e.g., ASM, listener).
C .False. It's file-based, not schema-based.
D .True. ADR logs (e.g., alert logs, trace files) are accessible even if the instance is down.
E .True. DIAGNOSTIC_DEST sets the ADR base directory.

NEW QUESTION # 71
Which three statements are true about Oracle Managed Files (OMF)?

A. If DB_CREATE_ONLINE_LOG_DEST_1 is specified but DB_CREATE_FILE_DEST is not, new data files and temp files are stored in DB_CREATE_ONLINE_LOG_DEST_1 by default.
B. If only DB_CREATE_FILE_DEST is specified, only data files and temp files are Oracle managed.
C. If DB_RECOVERY_FILE_DEST is specified but DB_CREATE_ONLINE_LOG_DEST_n is not, the redo logs and control files are placed in DB_RECOVERY_FILE_DEST by default.
D. If DB_CREATE_FILE_DEST is specified but DB_CREATE_ONLINE_LOG_DEST_n is not, new redo logs and control files are stored in DB_CREATE_FILE_DEST by default.
E. If DB_RECOVERY_FILE_DEST is specified, at least two different locations must be specified for DB_CREATE_ONLINE_LOG_DEST_n.
F. If only DB_CREATE_ONLINE_LOG_DEST_1 is specified, only redo logs and control files are Oracle Managed.

Answer: A,C,D

Explanation:
A .True. Without DB_CREATE_ONLINE_LOG_DEST_n, redo logs and control files default to DB_RECOVERY_FILE_DEST.
B .False. If only DB_CREATE_FILE_DEST is set, redo logs and control files also use it unless overridden.
C .True. DB_CREATE_ONLINE_LOG_DEST_1 becomes the default for data files and temp files if DB_CREATE_FILE_DEST is unset.
D .True. DB_CREATE_FILE_DEST serves as the default for all file types if no log-specific parameter is set.
E .False. Data files and temp files would also use DB_CREATE_ONLINE_LOG_DEST_1 if no other parameter is specified.
F .False. No such requirement exists; DB_RECOVERY_FILE_DEST operates independently.
