Which two partitioning methods are suitable for a parent table when using reference partitioning in Oracle Database 12c? (Choose two.)

Interval partitioning is not a supported partitioning method for the parent table when reference partitioning is used in Oracle 12c; the auto-extensible nature of interval partitions is incompatible with the reference partitioning mechanism.

List partitioning is not supported as a parent table partitioning strategy for reference partitioning in Oracle 12c; only range and hash are recognized parent strategies in this release.

System partitioning delegates partition management entirely to the application and has no partition key or constraint - making it structurally incompatible with the foreign-key-based inheritance required by reference partitioning.

Hash partitioning is a supported strategy for the parent table in a reference partitioning relationship. The child table inherits the same hash bucket count and distribution from the parent via the enforced foreign key, ensuring co-location of related rows.

Range partitioning is a supported strategy for the parent table in reference partitioning. The child table automatically inherits the parent's range boundaries through the foreign key constraint, allowing partition pruning and partition-wise joins without replicating the partition key in the child.
