Hi Yamini,
Sorry for replying late, But Good to know things even after completion of the exam.
According to spec 10.1.3 Entity Bean Providers Programming Contract


The container-managed persistent fields and container-managed relationship fields must not be defined in the entity bean class. From the perspective of the Bean Provider, the container-managed persistent fields and container-managed relationship fields are virtual fields only, and are accessed through get and set accessor methods. The implementation of the container-managed persistent fields and container-managed relationship fields is supplied by the container.

So the answer to your question YES both CMP and CMR are virtual fields

Hope that helps.
