ANSWERS

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

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

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

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

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

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

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

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

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

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