Module 2: Introduction to VMware Virtualization Flashcards
VMware VCP-DC 4 Certification
Virtualization is not:
Simulation
Emulation
As desktop and server processing capacity has increased, virtualization has helped:
- To simplify software development and testing
- To enable server consolidation
- To enhance datacenter agility and business continuity
What is simulation?
An imitation of a real thing or process
What is emulation?
Software that translates commands for the emulated hardware into commands the physical hardware can understand
What are the two types of VMware Virtualization architecture?
Hosted and Bare-metal hypervisor
The virtualization layer ________ _________ the available phyiscal resources (such as CPU, storage, memory, and I/O devices) across the virtual machines.
dynamically partitions
A host-based virtualization system requires an _________ to be installed on the computer.
operating system (such as Windows or Linux)
What are VMware host-based applications?
- VMware Server
- VMware Player
- VMware ACE
- VMware Workstation
- WMware Fusion
A bare-metal hypervisor system does not require an operating system. The ________ is the operating system.
hypervisor
In regards to hardware resources, why is a bare-metal hypervisor architecture more efficient?
It has direct access to the hardware
From the user’s prospective, what is a virtual machine?
A software platform that, like a physical computer, runs a operating system and applications
From the hypervisor’s prospective, what is a virtual machine?
A discrete set of files
What are the main virtual machine files?
- Configuration file
- Virtual disk file
- NVRAM settings file
- Log file
Virtual machines are ________. They can easily be backed up and cloned.
portable
A virtual machine is ________ of physical hardware and is ________ into files.
independent, encapsulated
Virtual machines are easy to manage because they are:
- isolated from other virtual machines
- insulated from hardware changes
vSphere consists of the following components:
- VMware vCenter Suite: The central point for configuring, provisioning, and managing virtualized IT environments.
- Application services: The services that provide application availability, security, and scalability
- Infrastructure services:The services that provide the virtual machine platform, storage capabilities, and network capabilities. ESX and ESXi are the virtualization platforms on which virtual machines run
