When ten containers are deployed on five virtual machines across two type 2 hypervisors, how many OS instances are running?

1. 2

2. 5

3. 7

4. 17

The correct answer is: 7

In this scenario, we need to consider the deployment of containers and how they relate to operating system instances. When using containers, each container shares the OS kernel with the host machine, allowing multiple containers to run on a single OS instance. Here, we have ten containers deployed across five virtual machines, which are managed by two type 2 hypervisors. Each virtual machine typically runs its own operating system instance as they simulate a complete hardware environment. Since there are five virtual machines, this indicates there are five separate operating system instances running on the hypervisors. To analyze further, while containers can run on a single OS instance, the key point is that they rely on the underlying virtual machines' operating systems. Since the deployment includes five virtual machines, it means there are five OS instances in total. Therefore, the correct understanding leads to a total of five operating system instances running alongside the ten containers spread across these virtual machines. Hence, the answer provided reflects the correct computation of OS instances based on the given information about the virtual machine allocation.
