D) all of the above

Question

All of the listed options are security concerns that can result from the use of virtualized systems.

A) Guest OS isolation: In a virtualized environment, multiple guest operating systems are running on a single physical machine. If one virtual machine (VM) is compromised, there is a risk that the attacker can move laterally to other VMs on the same host. Guest OS isolation helps to mitigate this risk by ensuring that each VM is contained within its own isolated environment.

B) Guest OS monitoring by the hypervisor: Monitoring the activity of guest operating systems is important for detecting and responding to security threats. The hypervisor is responsible for managing the virtualized environment, so it can monitor the activity of guest OSs running within that environment.

C) Virtualized environment security: A virtualized environment needs to be secured in the same way as a physical environment. This includes securing the host OS, the hypervisor, and the network connections between VMs.

Therefore, all of these options are valid security concerns that should be addressed when using virtualized systems.
