Oracle Database 23ai Administration Associate Sample Questions (Q71-Q76):

NEW QUESTION # 71
Which two statements are true about trace files produced by the Oracle Database server?

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

Answer: A,E

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 # 72
Which three statements are true about Deferred Segment Creation in Oracle databases?

A. It is supported for SYS-owned tables contained in locally managed tablespaces.
B. It is the default behavior for tables and indexes.
C. Indexes inherit the DEFERRED or IMMEDIATE segment creation attribute from their parent table.
D. It is supported for Index Organized Tables (IOTs) contained in locally managed tablespaces.
E. Sessions may dynamically switch back and forth from DEFERRED to IMMEDIATE segment creation.

Answer: B,C,E

Explanation:
A .False. IOTs require immediate segment creation.
B .False. SYS-owned tables don't use deferred creation.
C .True. Default since 11gR2, continued in 23ai.
D .True. Indexes inherit this attribute unless overridden.
E .True. Sessions can alter this via DEFERRED_SEGMENT_CREATION.

NEW QUESTION # 73
You have connected to a PDB to perform the administration operations of changing and verifying a system parameter that is PDB_MODIFIABLE. What is the appropriate mode to open the PDB to achieve this?

A. RESTRICTED WRITE ONLY
B. READ ONLY
C. RESTRICTED READ ONLY
D. READ WRITE

Answer: D

Explanation:
To change a PDB_MODIFIABLE parameter, the PDB must be in READ WRITE mode, allowing ALTER SYSTEM commands to modify parameters stored in the PDB's SPFILE or memory. READONLY modes prevent modifications, and no RESTRICTED WRITE ONLY mode exists.

NEW QUESTION # 74
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. A database link can be created only between two Oracle databases.
C. Private database link creation requires the same user to exist in both the local and the remote databases.
D. A public database link can be created only by SYS.
E. A public database link can be used by any user allowing remote database instance connection for selecting schema data.

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 # 75
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.CLEAN_AUDIT_TRAIL as a privileged user to manually purge audit records.
D. Only viewed audit records can be purged from Unified Audits.
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: C,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.
