C .True. ACLs restrict network access precisely.
D .False. TRUE relaxes dictionary access, violating least privilege.
E .False. TRUE allows risky OS auth, weakening security.

• C. It supports diagnostics for Oracle Clusterware.
• D. It is held inside an Oracle database schema.
• E. The ADR base defaults to $ORACLE_HOME/rdbms/admin if neither DIAGNOSTIC_DEST nor ORACLE_BASE is set.

Answer: B,C

Explanation:
A .False. ADR is file-based, not in a schema.

NEW QUESTION # 38
You are going to perform a hot remote clone of PDB1 from CDB1 as TESTPDB in CDB2. Which of the following is a necessary prerequisite for the hot remote clone?

• A. TESTPDB must be in read-only mode after the cloning process is complete.
• B. Both CDBs need to be in local undo mode.
• C. PDB1 must be taken offline before the cloning process begins.
• D. PDB1 must be in read-only mode.

Answer: D

Explanation:
C .True. Hot cloning requires the source PDB (PDB1) to be read-only to ensure consistency during the clone. Others are not prerequisites.

NEW QUESTION # 39
What is the result of the following command? ALTER PLUGGABLE DATABASE PDB1 DISCARD STATE;

• A. It is unnecessary if the PDB is in the process of being upgraded.
• B. PDB1 is reverted to its default properties, which includes not to automatically open after a CDB restart.
• C. PDB1 is reverted to its default properties, which includes automatic opening after a CDB restart.
• D. It should be used whenever PDB1 open mode needs to be changed.

Answer: B

Explanation:
A .False. DISCARD STATE isn't tied to upgrades; it resets PDB startup behavior.
B .True. Discards saved state, reverting PDB1 to manual open mode (not auto-open) after CDB restart.
C .False. Default is not auto-open; it's manual unless explicitly saved as OPEN.
D .False. Used for state management, not general mode changes (e.g., OPEN READ WRITE).

NEW QUESTION # 40

• B. The Large Pool
• C. The Shared Pool
• D. The Streams Pool

Answer: C

Explanation:
D .True. The Shared Pool caches data dictionary metadata (e.g., table definitions) in the Library Cache and Dictionary Cache, accessible to all processes. Others serve different purposes (e.g., Large Pool for backups).

NEW QUESTION # 45
Which three tasks are performed by background processes in an Oracle database instance?

• A. Reading database blocks into the buffer cache.
• B. Registering services with Oracle Net listeners.
• C. Creating dedicated server connections.
• D. Writing redo to log files.
• E. Writing dirty database block images from the buffer cache.
• F. Reading database blocks into the buffer cache.

Answer: B,D,E

Explanation:
False. Server processes (foreground) read blocks into the buffer cache during user queries, not background processes.
Explanation:
Background processes manage core database operations. Let's break it down:
A : Creating dedicated server connections.
False. Dedicated server connections are created by the listener, not background processes. The listener hands off the connection to a server process (e.g., ora_s000), which isn't a background process.
B : Registering services with Oracle Net listeners.
True. The LREG process (Listener Registration, formerly PMON's role) registers services with listeners, using parameters like LOCAL_LISTENER.
Mechanics:LREG sends service details (e.g., orcl) to the listener every 60 seconds or on startup.
C : Writing redo to log files.
True. The LGWR (Log Writer) process writes redo entries from the redo log buffer to online redo log files, ensuring transaction durability.
Mechanics:Triggered by commits, log buffer fills, or checkpoints.
D : Writing dirty database block images from the buffer cache.
True. The DBWn (Database Writer) processes write modified (dirty) blocks from the buffer cache to data files, maintaining consistency.
Mechanics:Occurs at checkpoints or when free buffers are needed.

NEW QUESTION # 46
What are Oracle Database Metrics?

• A. Oracle Database Metrics are part of the Oracle Database Notification system to email information about major database events.
• B. Oracle Database Metrics are a set of statistics built in Oracle Enterprise Manager Cloud Control and used for automation.
• C. Oracle Database Metrics are a set of measured statistics per unit of time (per second), transaction, or sessions that are used to evaluate performance.
• D. Oracle Database Metrics monitor performance using thresholds to generate alerts.
• E. Oracle Database Metrics are part of Oracle Enterprise Manager Cloud Control's Notification system used to email alerts.

Answer: C,D

Explanation:
A .True. Metrics (e.g., V$SYSMETRIC) use thresholds for alerts.
B .False. Metrics aren't tied to email notifications directly.
C .True. Metrics measure rates (e.g., IOPS, transactions/sec).
D .False. EMCC uses metrics, but they're DB-level, not EM-specific.
E .False. Metrics exist in the DB, not just EMCC.

NEW QUESTION # 47
Which statement regarding PDBs (Pluggable Databases) is correct?

• A. You can drop a PDB as long as it is not the PDB seed.
• B. You cannot drop a source PDB of a refreshable PDB.
• C. You can drop an application root along with the associated PDBs.
• D. When the relocation of a PDB is finished, the source PDB must be dropped.

Answer: A

Explanation:
A .True. Any PDB except PDB$SEED can be dropped.
B .False. Source PDBs of refreshable clones can be dropped after cloning.
C .False. Dropping an application root requires explicit handling of PDBs.
D .False. Relocation doesn't mandate dropping the source PDB.
