Box 2: Yes
A hybrid cloud is a combination of a private cloud and public cloud. Therefore, to create a hybrid cloud, you must deploy resources to a public cloud.

Box 3: No.
It is not true that a private cloud must be disconnected from the Internet. Private clouds can be and most commonly are connected to the Internet. “Private cloud” means that the physical servers are managed by you. It does not mean that it is disconnected from the Internet.
