Section B: True or False
Read each statement below carefully and state whether false or true.
(10 Maries)
1. Emulators are most useful when you need to test how software interacts with the
attached input devices.
2. The hypervisor is a layer of software that resides above the virtual machines and
below the hardware.
3. In RAIDSwrite data transactions are very fast while read data transactions are
somewhat slower.
4. Virtual machines are configured to run with one or more processors, depending on
the anticipated demand on the system.
5. Each virtual machine can be configured with only one network interface cards that
represent a connection to a network.
6. Server Virtualisation solves the problem of tight coupling between CPUand RAM
7. Virtualization does not allow multiple OS's and workloads to run on the same
physical hardware.
8. Emulation allows developers to see the real-time interactions between different
hardware and software models.
9. Full virtualisation technique uses hardware emulation.
10. The main files that make up a VM are the configuration file and the virtual disk files.
