Question

In OpenStack, when a VM is terminated, which of the following resources are freed?

Answer 1

(c) Ephemeral storage, all IPs, RAM and vCPUs

Answer 2

OpenStack: OpenStack is a opensource cloud computing platform which is deployed as an Infrastructure as A Service. (IaAs)

They provide Virtual machine services.

Virtual Machine: A VM is a software application that works like a physical machine and runs the operating system.

So once the VM is terminated, all the resources including the Ephemeral storage, all IPs, RAM and vCPUs are freed. Because, the VM controls the entire OS. Ephemeral storage, all IPs, RAM and vCPUs run in the OS memory. So, upon termination of the VM all the resources are freed.

The answer is (c) Ephemeral storage, all IPs, RAM and vCPUs.
