NEW QUESTION # 24
Which two methods can be used to purge audit records of the Unified Audits?
- A. Only the owner of a Unified Audit Policy can purge audit records by resetting the policy.
- B. Use DBMS_AUDIT_MGMT.CLEAN_AUDIT_TRAIL as a privileged user to manually purge audit records.
- C. Use DBMS_AUDIT_MGMT.CREATE_PURGE_JOB as a privileged user to schedule an automatic purge job.
- 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. Only viewed audit records can be purged from Unified Audits.
- 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: B,C
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 # 26
You execute this command: [oracle@host01 ~]$ expdp system/oracle FULL=Y DUMPFILE=exp_db_full.dmp PARALLEL=4 LOGFILE=exp_db_full.log JOB_NAME=exp_db_full. During the export operation, you detach from the job by using CTRL+C and then execute this command: Export> STOP_JOB=IMMEDIATE. Are you sure you wish to stop the job ([yes]/no): yes. Which two statements are true about the job?
- A. It continues to run in the background.
- B. You cannot monitor it.
- C. It terminates.
- D. You can reattach to it and monitor it.
Answer: C,D
Explanation:
A .False. STOP_JOB=IMMEDIATE halts the job, not backgrounds it.
B .False. You can monitor before stopping or after restarting.
C .True. Before stopping, you can reattach with expdp attach=exp_db_full.
D .True. STOP_JOB=IMMEDIATE terminates the job instantly.
NEW QUESTION # 27
Which two statements describe why Database Auditing is a security requirement?

- B. To protect against data theft by a non-authorized user.
- C. To protect against data corruption.
- D. To monitor suspicious activity.
- E. To alert DBAs about system issues.
Answer: A,D
Explanation:
A .True. Auditing tracks suspicious actions.
B .False. That's monitoring, not auditing.
C .False. Auditing detects, doesn't prevent.
D .False. Corruption is a reliability issue.
E .True. Ensures privileged user compliance.

- A. One instance on one server mounting and opening multiple databases.
- B. One instance on one server mounting multiple databases.
- C. One instance on one server that has no database mounted.
- D. Two or more instances on separate servers all mounting and opening the same database.
- E. One instance on one server mounting and opening one database.
