Oracle Database 23ai Administration Associate 認定 1Z1-182 試験問題 (Q35-Q40):

質問 # 35
How do you validate that the database was migrated to Unified Auditing?

A. By querying the DBA_UNIFIED_AUDIT_OPTION view.
B. By using the LSINVENTORY Command to query the Oracle Database Software Library.
C. By executing DBMS_AUDIT_MGMT PL/SQL package in Verify mode.
D. By querying V$OPTION for parameter Unified Auditing.

正解：D

解説：
Unified Auditing is enabled at database creation or migration in 23ai. Let's analyze:
A . By querying V$OPTION for parameter Unified Auditing.
True. SELECT VALUE FROM V$OPTION WHERE PARAMETER = 'Unified Auditing'; returns TRUE if enabled. It's the definitive way to confirm Unified Auditing is active at the database level.
Mechanics:V$OPTION reflects compiled-in features; TRUE indicates the binary was linked with Unified Auditing (uniauflt=on during relink).
Practical Use:Quick, reliable check post-migration or upgrade.
B . By using the LSINVENTORY Command to query the Oracle Database Software Library.
False. LSINVENTORY (from OPatch) lists installed software components, not runtime features like auditing mode.
C . By querying the DBA_UNIFIED_AUDIT_OPTION view.
False. This view doesn't exist; DBA_AUDIT_POLICIES or UNIFIED_AUDIT_TRAIL show policies and records but not migration status.
D . By executing DBMS_AUDIT_MGMT PL/SQL package in Verify mode.
False. No "Verify mode" exists in DBMS_AUDIT_MGMT; it manages audit trails, not migration validation.

質問 # 36
Which two statements are true regarding Oracle database space management within blocks managed by Automatic Segment Space Management (ASSM)?

A. ASSM assigns blocks to one of the four fullness categories based on what percentage of the block is allocated for rows.
B. Update operations always relocate rows into blocks with free space appropriate to the length of the row being updated.
C. PCTFREE defaults to 10% for all blocks in all segments for all compression methods.
D. Insert operations always insert new rows into blocks with free space appropriate to the length of the row being inserted.
E. The first block with enough free space to accommodate a row being inserted will always be used for that row.

正解：A、D

解説：
A .True. ASSM categorizes blocks (e.g., 0-25%, 25-50%) for efficient space use.
B .False. Updates may cause chaining/migration, not always relocation.
C .True. ASSM optimizes inserts into suitable blocks.
D .False. ASSM uses a bitmap, not necessarily the first block.
E .False. PCTFREE is segment-specific, not universally 10%.

質問 # 37
In the SPFILE of a single instance database, LOCAL_LISTENER is set to LISTENER_1. The TNSNAMES.ORA file in $ORACLE_HOME/network/admin in the database home contains: LISTENER_1 = (ADDRESS = (PROTOCOL = TCP)(HOST = host1.abc.com)(PORT = 1521)). Which statement is true?

A. Dynamic service registration cannot be used for this database instance.
B. There are two listeners named LISTENER and LISTENER_1 running simultaneously using port 1521 on the same host as the database in LISTENERS.
C. LISTENER_1 must also be defined in the LISTENER.ORA file to enable dynamic service registration.
D. The LREG process registers services dynamically with the LISTENER_1 listener.
E. The definition for LISTENER_1 requires a CONNECT_DATA section to enable dynamic service registration.

正解：D

解説：
Dynamic service registration allows a database to automatically register its services with a listener without manual configuration in LISTENER.ORA. Let's analyze each option:
A . The definition for LISTENER_1 requires a CONNECT_DATA section to enable dynamic service registration.
False. The CONNECT_DATA section is part of a client-side TNSNAMES.ORA entry for connecting to a service, not for listener registration. Dynamic registration is handled by the database's LREG (Listener Registration) process, which uses the LOCAL_LISTENER parameter to locate the listener's address (e.g., host1.abc.com:1521). No CONNECT_DATA is needed in the listener address definition itself. This option confuses client connection syntax with listener configuration.
Mechanics:The listener address in TNSNAMES.ORA (LISTENER_1) is sufficient for LREG to find and register with it, as long as the listener is running at that address.
B . LISTENER_1 must also be defined in the LISTENER.ORA file to enable dynamic service registration.
False. Dynamic registration doesn't require the listener to be explicitly defined in LISTENER.ORA. The LOCAL_LISTENER parameter pointing to LISTENER_1 (resolved via TNSNAMES.ORA) tells LREG where to register services. If the listener is running on host1.abc.com:1521, LREG will find it without a LISTENER.ORA entry. However, LISTENER.ORA is needed tostartthe listener process, but that's separate from dynamic registration.
Practical Note:If LISTENER.ORA isn't configured, a default listener might run on port 1521, but the question implies LISTENER_1 is operational.
C . The LREG process registers services dynamically with the LISTENER_1 listener.
True. In Oracle 23ai, the LREG background process (replacing PMON's registration role in earlier versions) dynamically registers database services with listeners specified by LOCAL_LISTENER. Here, LOCAL_LISTENER=LISTENER_1 resolves to host1.abc.com:1521 via TNSNAMES.ORA. LREG periodically sends service information (e.g., service names, instance details) to the listener, enabling clients to connect without static configuration.
Mechanics:LREG uses the TNS alias (LISTENER_1) to locate the listener's IP and port, registers services like orcl or orclpdb, and updates the listener's service table. This happens automatically every 60 seconds or on significant events (e.g., instance startup).
D . Dynamic service registration cannot be used for this database instance.
False. The setup (LOCAL_LISTENER set and a valid TNSNAMES.ORA entry) explicitly supports dynamic registration. No blockers (e.g., REGISTRATION_EXCLUDED_LISTENERS) are mentioned, so LREG can function normally.
E . There are two listeners named LISTENER and LISTENER_1 running simultaneously using port 1521 on the same host as the database in LISTENERS.
False. The question mentions only LISTENER_1 in the SPFILE and TNSNAMES.ORA. There's no evidence of a second listener (LISTENER) or a LISTENERS configuration (possibly a typo). Two listeners can't share the same port (1521) on the same host due to port conflicts unless explicitly configured with different IPs, which isn't indicated here.

質問 # 38
Which two actions can you perform using DBCA for an existing database?

A. Create nonstandard block size tablespaces.
B. Change the character set.
C. Create an additional listener.
D. Create a template that can be used to clone the database.
E. Change the server mode from dedicated to shared, and vice versa.

正解：D、E

解説：
A .False. DBCA can't change character sets post-creation.
B .False. Listeners are managed via NetCA or lsnrctl.
C .True. DBCA can switch server modes for existing DBs.
D .False. Tablespaces are created via SQL, not DBCA for existing DBs.
E .True. DBCA can generate clone templates from existing DBs.

質問 # 39
Which four statements are true about the Oracle Server architecture?

A. A session represents the state of a user's login to an instance.
B. The buffer cache and the redo log buffer are held in the large pool.
C. Each server process or background process has their own Program Global Area (PGA).
D. A person or program can have more than one session with an instance by logging in with different users.
E. A connection represents the state of a user's login to an instance.
F. A person or program can have more than one session with an instance by logging in with the same user.

正解：A、C、D、F

解説：
A .True. Multiple sessions with different users are possible.
B .False. Buffer cache and redo log buffer are in SGA, not large pool.
C .True. Session tracks login state.
D .True. Each process has its own PGA.
E .False. Connection is the network link; session is the state.
F .True. Same user can have multiple sessions (e.g., via different terminals).
