Mcqs question on version of oracle for multi-version read consistency

The latest release Oracle 11g supports multi-version read consistency.

Multiple versions of the data can be materialized and the following features are offered:

1)  The data obtained by a committed query is always consistent.

2)  No dirty reads is allowed where uncommitted data is read by a transaction.

3)  Database readers and database writers can't block each other.

For more details on Oracle consistency you should check Oracle official documentation.
