T/F: Virtualization can create isolated environments, preventing guests from interfering with each other.

true

T/F: The JVM (Java Virtual Machine) allows programs to run across different platforms without the need for recompilation.

true

T/F: Virtualization only applies to operating systems and has no use for networks or storage.

false

T/F: Virtualization can help reduce power consumption by consolidating servers.

true

T/F: The primary purpose of the Xen hypervisor is to support full hardware virtualization without any modifications to the guest OS.

false

T/F: Virtualization is a technology that enables the creation of isolated environments for running untrusted applications.

true

T/F: Hyper-V requires an existing operating system installation to function as it is not directly installed on bare hardware.

true
