An application has three entities: the mapped super class person class entity, and the parent and child entities, which are subclasses of person. The application has created four entity Instances:

Person1 is a Person entity with a primary key of 50 Parent1 is a Parent entity with a primary key of 100 Child1 is a chi id entity with a primary key of 400 Child2 is a child entity with a primary key of 600 Caching has been enabled in the persistence unit, the persistence provider supports caching, and none of entities have the Cacheable annotation applied, or a cacheable XML element in persistence.xml. The application executes the following code:

Cache cache = . . . ; Cache.evict(person.class) Boolean result = cache.contains (Child.class, 400); Assume there is no concurrent activity involving the cache. Which two statements are correct? (Choose two)
