C. It must be bigger than the largest SMALLFILE tablespace.
D. It will always have a 32K blocksize.
E. AUTOEXTEND is possible for the datafile.

Answer: A,E

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.

NEW QUESTION # 30
What is the result of the following command? ALTER PLUGGABLE DATABASE PDB1 DISCARD STATE;

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

Answer: A

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 # 31
Which three tasks are performed by background processes in an Oracle database instance?

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

Answer: C,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 # 32
Which four statements are true about the Oracle Server architecture?

A. A connection represents the state of a user's login to an instance.

D. A person or program can have more than one session with an instance by logging in with the same user.
E. The buffer cache and the redo log buffer are held in the large pool.
F. Each server process or background process has their own Program Global Area (PGA).

Answer: B,C,D,F

Explanation:
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).
