NO.56 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?

The definition for LISTENER_1 requires a CONNECT_DATA section to enable dynamic service registration.

LISTENER_1 must also be defined in the LISTENER.ORA file to enable dynamic service registration.

The LREG process registers services dynamically with the LISTENER_1 listener.

Dynamic service registration cannot be used for this database instance.

There are two listeners named LISTENER and LISTENER_1 running simultaneously using port 1521 on the same host as the database in LISTENERS.

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.

NO.57 You must create a tablespace of nonstandard block size in a new file system and plan to use this command: CREATE TABLESPACE ns_tbs DATAFILE ‘/u02/oracle/data/nstbs_f01.dbf’ SIZE 100G BLOCKSIZE 32K; The standard block size is 8K, but other nonstandard block sizes will also be used. Which two are requirements for this command to succeed?

DB_32K_CACHE_SIZE must be less than DB_CACHE_SIZE.

DB_32K_CACHE_SIZE must be set to a value that can be accommodated in the SGA.

The operating system must use a 32K block size.

DB_32K_CACHE_SIZE should be set to a value greater than DB_CACHE_SIZE.

The /u02 file system must have at least 100G space for the datafile.

NO.58 Which two statements are true about the PMON background process?

It registers database services with all local and remote listeners known to the database instance.

It records checkpoint information in the control file.

It frees resources held by abnormally terminated processes.

It rolls back transactions when a process fails.

It frees unused temporary segments.

NO.59 What memory structure caches the data dictionary providing access to all database user processes?

The Large Pool

The Java Pool

The Streams Pool
