A) Private clouds can be hosted at your datacenter or hosted by a third-party service. Private clouds offer advantages of flexibility, control, and scalability.
Microsoft defines private clouds as being able to be hosted at your datacenter or hosted by a third-party service. Microsoft considers private clouds as offering more flexibility, control, and scalability. Note: Other cloud vendors would not agree with those advantages of private clouds, but it is best to be aware of Microsoft’s view in case it comes up on the exam.
C) A hybrid cloud combines a public cloud (such as Azure) with on-premises infrastructure (private cloud).
Microsoft defines hybrid cloud as combining a public cloud (such as Azure) with on-premises infrastructure (private cloud).
D) In private clouds, services and infrastructure are always maintained on a private network, and the hardware and software are dedicated solely to your organization.
A private cloud consists of cloud computing resources used exclusively by one business or organization. The private cloud can be physically located at your organization’s on-site datacenter, or it can be hosted by a third-party service provider. But in a private cloud, the services and infrastructure are always maintained on a private network, and the hardware and software are dedicated solely to your organization.

C) At any time, as long as your resources or resource group are not locked by a related service
D) When all the resources in the resource group have stopped
C) At any time, as long as your resources or resource group are not locked by a related service
When a resource group is removed or deleted, all of the resources within it are deleted with it. You can remove resource groups at any time. To delete a resource group, you need access to the delete action. You also need delete for all resources in the resource group. If you have the required access, but the delete request fails, it may be because there’s a lock on the resources or resource group. Even if you didn’t manually lock a resource group, it may have been automatically locked by a related service. Or, the deletion can fail if the resources are connected to resources in other resource groups that aren’t being deleted. For example, you can’t delete a virtual network with subnets that are still in use by a virtual machine.
