Lesson 1: Deploying and Managing Server Images Flashcards
WDS
Windows Deployment Services
performs automated network-based installations based on network-based boot and installation media.
What can WDS be used to deploye?
Windows XP, Vista, 7, 8, Server 2003, 2012
Image File
a snapshot of a computer’s hard drive taken at a particular moment in time.
Image Files are also referred to as
install image
PXE
Preboot execution environment.
technology that boots computers using the network interface without a data storage device, such as a hard drive or an installed operating system.
For client computers to communicate with a WDS server without an operating system, the client computer must have support ____
PXE
PXE is pronounced
“pixie”
Windows PE
Windows Preinstallation Environment
minimal Windows operating system with limited services.
Used to install an OS over PXE using WDS
2 role services of WDS
Deployment Server
Transport Server
WDS – Deployment Server component
Provides full functionality of WDS, including an image repository.
WDS - Transport Server component
Allows for multicasting, which the deployment server component does not.
Network requirements before WDS can be run.
Server must be a member or the DC of the domain
Must have an active DHCP server on the network
Must have an active DNS server on the network
The WDS server has an NTFS file system partition to store images.
2 images required to deploy windows via WDS
Boot Image
Install Image
WDS - Boot Image
image used to boot the system to start the OS install
WDS - Install Image
image used by WDS to install the OS
2 types of image formats
Sector based image formats
file-based image formats
Sector-based image formats
each sector is stored within the file and each sector is the smallest unit of information. One common example of a disk image is the .ISO file used for a CD image and a DVD image.
file-based image formats
each file is the smallest unit. The advantage of using a file-based image is that it is hardware-independent and a file can be referenced multiple times within the file system tree.
Advantage of file-based image formats over sector-based image formats
By using a database, the system does not have to open and close several individual files during the data transfer.
What file format is used by WDS
WIM
WIM
Windows Imaging Format
File format used by WDS
Which image format type is WIM
file-based
allows a file structure (folders and files) to be stored inside a single WIM database.
Image Group
folder within the image repository of WDS that shares security options and file resources.
Images inherit their group’s security options and file resources
Two components of an image group
Res.wim file – contains resources and security options for all images in the group.
.wim file - Each .wim image file in the group
Besides using the install images that come on a Windows Installation disk, how do you create an image?
(For example, a customized image?)
Windows Deployment Services Capture Utility
Windows Deployment Services Capture Utility
will create an image file and write it to the computer’s drive, which will eventually be copied to the WDS server. You can then use it to be deployed to other computers.
If a PC does not support PXE, how can you set it up to boot to a WDS server?
Using a discover image, burned to DVD/CD – boot from that.
discover image
image file that you can burn to a CD-ROM or other boot medium. When you boot the client computer using the discover image disk, the computer loads Windows PE, connects to a specified WDS server, and proceeds with the operating system installation process.
Unlike other components of Server2012, you can’t use ___ to configure WDS
PowerShell
What command do you use to configure WDS, since there isn’t PowerShell support?
wdsutil
Answer Files
provide responses to the prompts that would normally appear during the Windows installation. Besides clicking the standard Next button used on most screens, the answer file can also be used to partition and format disk, install additional device drivers, and specify what Windows features to install.
System Image Manager (SIM)
a tool used to create and manage unat- tended Windows setup answer files using a graphical interface. SIM can also be used to check answer files.
DISM
Deployment Image Servicing and Management
a command-line tool that can be used to service a Windows image or to prepare a Windows PE image. With Dism, you can mount an image offline and then add, remove, update, or list the features, packages, drivers, or international settings stored on that image.
