1. What does the following figure represent?

a) vSquare cloud infrastructure
b) vCube cloud infrastructure
c) vSphere cloud infrastructure
d) None of the mentioned
View Answer

Answer: c
Explanation: vSphere is the branding for a set of management tools and a set of products previously labeled VMware Infrastructure.

2. Point out the wrong statement.
a) Some hypervisors are installed over an operating system and are referred to as Type 2 or hosted VM
b) All CPUs support virtual machines
c) On a Type 2 VM, a software interface is created that emulates the devices with which a system would normally interact
d) All of the mentioned
View Answer

Answer: b
Explanation: Not all CPUs support virtual machines and many that do require that you enable this support in the BIOS.

3. Which of the following type of virtualization is found in hypervisor such as Microsoft’s Hyper-V?
a) paravirtualization
b) full virtualization
c) emulation
d) none of the mentioned
View Answer

Answer: a
Explanation: It is the host operating system that is performing the I/O through a para-API.

4. In _______ the virtual machine simulates hardware, so it can be independent of the underlying system hardware.
a) paravirtualization
b) full virtualization
c) emulation
d) none of the mentioned
View Answer

Answer: c
Explanation: A guest operating system using emulation does not need to be modified in any way.

5. Point out the wrong statement.
a) Full virtualization requires that the host operating system provide a virtual machine interface for the guest operating system and that the guest access hardware through that host VM
b) Guest operating systems in full virtualization systems are generally faster than other virtualization schemes
c) A process virtual machine instantiates when a command begins a process
d) All of the mentioned
View Answer

Answer: a
Explanation: An operating system running as a guest on a paravirtualization system must be ported to work with the host interface.

6. In a ____________ scheme, the VM is installed as a Type 1 Hypervisor directly onto the hardware.
a) paravirtualization
b) full virtualization
c) emulation
d) none of the mentioned
View Answer

Answer: b
Explanation: All operating systems in full virtualization communicate directly with the VM hypervisor.

7. Which of the following operating system support operating system virtualization?
a) Windows NT
b) Sun Solaris
c) Windows XP
d) Compliance
View Answer

Answer: b
Explanation: This type of virtualization creates virtual servers at the operating system or kernel level.

8. Which of the following is a service that aggregates servers into an assignable pool?
a) VMware vStorage
b) VMware vNetwork
c) VMware vCompute
d) Application services
View Answer

Answer: c
Explanation: VMware vSphere is a management infrastructure framework that virtualizes system, storage, and networking hardware to create cloud computing infrastructures.

9. _________ is a service that creates and manages virtual network interfaces.
a) VMware vStorage
b) VMware vNetwork
c) VMware vCompute
d) Application services
View Answer

Answer: b
Explanation: VMware vStorage is a service that aggregates storage resources into an assignable pool.

10. Which of the following allows a virtual machine to run on two or more physical processors at the same time?
a) Virtual SMP
b) Distributed Resource Scheduler
c) vNetwork Distributed Switch
d) Storage VMotion
View Answer

Answer: a
Explanation: The virtualization layer that abstracts processing, memory, and storage uses the VMware ESX or ESXi virtualization server.

What is the physical machine that runs the VMs?

The physical machines, equipped with a hypervisor such as Kernel-based Virtual Machine (KVM), is called the host machine, host computer, host operating system, or simply host.

What is the name of the software that runs the virtual systems?

A hypervisor, also known as a virtual machine monitor or VMM, is software that creates and runs virtual machines (VMs). A hypervisor allows one host computer to support multiple guest VMs by virtually sharing its resources, such as memory and processing.

What is a physical hypervisor?

While a physical server is a single-tenant platform with dedicated resources, a hypervisor can support multiple virtual servers, allowing multiple applications to run simultaneously and share physical hardware capacity amongst themselves.

What is the virtualization software?

Virtualization uses software to create an abstraction layer over computer hardware that allows the hardware elements of a single computer—processors, memory, storage and more—to be divided into multiple virtual computers, commonly called virtual machines (VMs).
