D .True. SGA is allocated at startup.
E .False. SYS access requires OPEN.

NEW QUESTION # 34
Which two statements are true about advanced connection options supported by Oracle Net for connection to Oracle?

A. Connect Time Failover requires the connect string to have two or more listener addresses configured.
B. Load Balancing can balance the number of connections to dispatchers when using a Shared Server configuration.
C. Connect Time Failover requires the use of Transparent Application Failover (TAF).
D. Load Balancing requires the use of a name server.
E. Source Routing requires the use of encrypted connections.

Answer: A,B

Explanation:
A .False. Connect Time Failover doesn't need TAF; TAF is for runtime failover.
B .False. Source Routing doesn't mandate encryption.
C .True. Needs multiple addresses (e.g., (ADDRESS_LIST=...)) for failover.
D .False. Load balancing works with tnsnames.ora, no name server required.
E .True. Balances connections across shared server dispatchers.

NEW QUESTION # 35
Which three statements are true about dynamic performance views?

A. They can be queried only when the database is open.
B. Data displayed by querying dynamic performance views is derived from metadata in the data dictionary.
C. Read consistency is not guaranteed.
D. V$FIXED_TABLE can be queried to display the names of all dynamic performance views.
E. They are owned by the SYSTEM user.

Answer: B,C,D

Explanation:
A .True. V$ views reflect real-time memory data, not consistent snapshots.
B .True. V$FIXED_TABLE lists all V$ views.
C .True. Data comes from memory structures and data dictionary metadata.
D .False. Owned by SYS, not SYSTEM.
E .False. Some V$ views are accessible in MOUNT state.

NEW QUESTION # 36
Which two statements are true about the configuration and use of UNDO?

A. UNDO_RETENTION specifies for how long Oracle attempts to keep expired and unconsumed UNDO.
B. UNDO_RETENTION specifies for how long Oracle attempts to keep unexpired UNDO.

C .False. Applies to unexpired, not expired UNDO.
D .False. Only unexpired UNDO is targeted.
E .True. UNDO_RETENTION sets the retention goal for unexpired UNDO.

NEW QUESTION # 37
Which three are benefits of using temp UNDO when performing DML on global temporary tables?

A. It permits DML on global temporary tables even if the database is opened read-only.
B. It reduces I/Os to the SYSTEM tablespace.
C. It reduces the amount of UNDO stored in the UNDO tablespace.
D. It reduces I/Os to the SYSAUX tablespace.
E. It reduces the amount of redo generated.

Answer: B,C,E

Explanation:
Temp UNDO, introduced in Oracle 12c and refined in 23ai, stores undo for global temporary tables (GTTs) in temporary tablespaces:
A . It permits DML on GTTs even if the database is opened read-only.False. In read-only mode, DML on GTTs is allowed regardless of temp UNDO, as GTT data is session-private, but temp UNDO doesn't specifically enable this.
B . It reduces the amount of UNDO stored in the UNDO tablespace.True. Temp UNDO stores undo in the temporary tablespace, reducing usage of the permanent UNDO tablespace.
C . It reduces I/Os to the SYSTEM tablespace.True. By avoiding permanent undo, it reduces metadata updates in the SYSTEM tablespace related to undo management.
D . It reduces the amount of redo generated.True. Temp UNDO changes are not redo-logged to the same extent as permanent undo, minimizing redo generation.
E . It reduces I/Os to the SYSAUX tablespace.False. SYSAUX is unrelated to undo management; temp UNDO affects temporary and SYSTEM tablespaces.
