Oracle Database 23ai Administration Associate Sample Questions (Q47-Q52):

NEW QUESTION # 47
Which two methods can be used to purge audit records of the Unified Audits?

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

Answer: D,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 # 48
Which data dictionary view describes the data sources of external tables?

A. DBA_ALL_USER_EXTERNAL_LOCATIONS
B. DBA_ALL_USER_TAB_COLUMNS
C. DBA_ALL_USER_EXTERNAL_TABLES
D. DBA_ALL_USER_TABLES

Answer: A

Explanation:
A .True. DBA_EXTERNAL_LOCATIONS (or prefixed variants) shows external table data sources (e.g., file paths).
B-D .False. These views cover columns or tables but not external sources specifically.

NEW QUESTION # 49
Which two statements are true about the DUAL table?

A. It can display multiple rows and columns.
B. It consists of a single row and single column of VARCHAR2 data type.
C. It can display multiple rows but only a single column.
D. It can be accessed only by the SYS user.
E. It can be accessed by any user who has the SELECT privilege in any schema.
F. It can be used to display only constants or pseudo columns.

Answer: B,E

Explanation:
A .True. DUAL is public; any user with SELECT can query it.
B .True. One row, one VARCHAR2 column (DUMMY).
C .False. Fixed at one row.
D .False. Not restricted to SYS.
E .False. One row, one column only.
F .False. Can return expressions, not just constants.

NEW QUESTION # 50
Which two statements are true about trace files produced by the Oracle Database server?

A. They can be written by background processes to a file system.
B. Trace file names are based on the database name concatenated with a sequential number.
C. They can be written by server processes to a file system.
D. They can be written by server processes to the Fast Recovery Area (FRA).
E. All trace files contain error information that requires contacting Oracle Support.

Answer: A,C

Explanation:
A .False. Not all trace files indicate errors; some log normal activity.
B .True. Server processes write traces (e.g., ora_s000_123.trc) to the file system.
C .True. Background processes (e.g., ora_lgwr_123.trc) also write traces.
D .False. Names include process type and PID, not just DB name and sequence.
E .False. Traces go to DIAGNOSTIC_DEST, not necessarily FRA unless configured there.

NEW QUESTION # 51
You execute this command: CREATE BIGFILE TABLESPACE big_tbs DATAFILE '/u01/oracle/data/big_f1.dbf' SIZE 20G; Sufficient storage is available in filesystem /u01. Which two statements are true about the BIG_TBS tablespace?

A. It must be bigger than the largest SMALLFILE tablespace.
B. Additional data files may not be added.
C. It will be a dictionary-managed tablespace by default.
D. AUTOEXTEND is possible for the datafile.
E. It will always have a 32K blocksize.

Answer: B,D

Explanation:
A .False. LMT is default in 23ai.
B .True. Bigfile tablespaces have one data file only.
C .True. AUTOEXTEND works with bigfile data files.
D .False. Block size defaults to DB_BLOCK_SIZE (e.g., 8K).
E .False. No size comparison requirement.
