Which of the following is a risk that stems from a virtualized environment? Response:

The ability to live migrate virtual machines between physical hosts, while a beneficial feature for resource balancing and maintenance, poses a security risk. This dynamic movement can complicate network security, making it harder to track VM locations for policy enforcement, potentially bypassing host-based firewalls, or creating "VM sprawl" where unmanaged VMs proliferate across the network without proper security controls.

Cloud data centers becoming a single point of failure is a risk associated with cloud computing generally, not specifically stemming from virtualized environments themselves, as virtualization can also be on-premises.

Difficulty in finding multiple utility providers relates to physical datacenter resilience, not a direct risk from the virtualization technology itself.

Stringent SLA demands are a business challenge with cloud providers but not a direct risk stemming from the virtualized environment technology.
